razgon-processora-biosMany owners of old PCs and laptops want to somehow speed up the operation of these devices with the least investment of money. One of the most popular methods to improve performance is overclocking the CPU through the BIOS. In this topic, we will tell you what overclocking is and how to overclock a processor through the BIOS of Asus, Gigabyte and its other versions.

What is overclocking?

Overclocking a processor means increasing its clock frequency. Clock speed is the number of operations that the CPU processes in one second of real time (that is, it is one clock cycle per second). Based on this, the higher the clock frequency of the CPU, the correspondingly more clock cycles per unit of time it is able to process.

The frequency of any CPU in a PC or laptop consists of two important parameters: the multiplier product and the bus frequency. Bus frequency is the clock frequency (that is, the speed) at which data is exchanged between the CPU and the computer's RAM. The multiplier is the number by which the bus frequency is multiplied.

We get that multiplier * bus frequency = processor clock speed. Going back a little, we find that to overclock the processor, you need to increase some of these values. Knowing what these parameters are and their values, you can better understand how the processor works and what is needed to improve its speed.

Such operations can be performed both through the BIOS and by using third-party programs. In this topic, we will discuss the first option.

CPU overclocking

Before starting to describe the whole process, we want to clarify that there are several BIOS variations, in which the appearance, the name of the partitions and their location may differ. One way or another, they are more or less similar one to one. Therefore, if you do not have the same points that we are talking about, then try to find something similar for yourself. As a result, no matter what version of BIOS you work with, you will still only change two parameters, which are available in all versions and have the same name. Here we will describe overclocking using the AMI BIOS as an example.

BIOS setup for overclocking the processor is carried out as follows:

  1. You need to enter BIOS. This can be done when starting the PC by constantly pressing a certain key or a combination of them. Usually, this is the "Del", "F2" or "F8" button (for laptops, these can be combinations of these keys with the Fn button pressed at the same time), but these buttons may differ from developer to developer.
  2. Select the "Advanced" tab.
  3. Set the “Ai Overlock Tuner” to “Manual”. This will give you access to the previously hidden CPU settings. BIOS-overlock-tuner-manual
  4. Pay attention to the two parameters that appear:
    • "CPU Ratio Rating" - multiplier
    • "FSP Frequency" - bus frequency

    ration-setting-i-frequency

If you missed the information about what it is, then return to the beginning of the topic, where we explained it as clearly as possible. By increasing the values ​​of these fields, you will speed up the processor.

To the question "Which of these two parameters is best to increase?" there is an extremely simple answer. First, on very old processors, the multiplier can be completely locked for changes. In this case, you have only one option.

If the multiplier is unlocked, then it is recommended to change it, because it will be safer for the system. Accelerating the bus frequency will affect other components and their operating speed, as a result of which something may simply burn out.

If you have already changed something, you want to return everything back, but do not know how - just reset the BIOS settings to the factory settings.

When adjusting the BIOS for overclocking, do it very carefully: adjusting the same multiplier, gradually add its value up by one, then save the changes and restart the PC. After that, conduct a stress test and conclude whether you need to increase more (the same with frequency).

Outcome

We hope, after reading this material, you now know how to overclock a processor via BIOS from Asus, Gigabyte or any other. Most likely, during the process you will have questions - write them under this topic and we will help you cope with all the difficulties in your work.

How to overclock the processor in BIOS

By the term "overclocking" most users mean exactly the increase in the performance of the central processor. In modern models of motherboards, this procedure can also be carried out from under the operating system, but the most reliable and universal method is setting through the BIOS. It is about him that we want to talk today.

Overclocking the CPU through BIOS

Before starting the description of the techniques, we will make several important notes.

The actual BIOS setup begins with entering the interface shell. If you do not know how this is done on your device, use the guide on the link below.

Good day! After you have learned what overclocking is, it would be logical to dwell on the question in more detail, how to overclock the processor and what is it all about CPU overclocking ... And very soon you will learn how to overclock your RAM. Yes, you can do that too! And we finally have an article about overclocking a video card.

By overclocking the processor, you risk permanently incapacitating it. Be careful and attentive. The site administration is not responsible for your actions after reading this article.

Additional utilities for overclocking the processor

First of all, in order to overclock the processor, you need a small set of utilities that will help you monitor the state of your system and its stability, as well as the temperature of the processor. Below we list a list of utilities and programs and briefly describe what they are responsible for.

CPU-Z - a small but very useful utility that will show all the basic technical information of your CPU. Useful for tracking frequencies and voltages. Free.

How to overclock a processor?

CPU-Z

CoreTemp - another free utility, somewhat similar to CPU-Z, but does not go deep into technical indicators, but displays the temperature of the processor cores and their load.

Speccy - shows detailed technical information not only about the processor, but also about the entire computer as a whole. There is also information about the temperatures of various components of the system.

LinX - a free program that we need to test the stability of the system after each stage of increasing processor performance. It is one of the best stress test software. It loads the processor at 100%, so do not be alarmed, sometimes it may seem that the computer is frozen.

Overclocking the processor

Before learning how to overclock a processor, I highly recommend stress-testing your computer in a non-overclocked state (for example, with the program FurMark ). This is necessary in order to determine the approximate potential for overclocking and generally check the system for errors.

Overclocking the processor. FurMark stress test

If in the non-overclocked state the test gives any errors or the temperature during testing is prohibitively high, then it is better to finish your "overclocking" at this point.

If everything works stably and the processor temperature is normal, then we can continue. And you better note for yourself the key characteristics of an overclocked system, such as minimum CPU temperature, maximum CPU temperature, voltage, etc. Better yet, take a screenshot of the screen or take a picture on your phone so that you have detailed information at hand, just in case. This is necessary to analyze the deviations of indicators from the nominal. Not critically important, but very useful and curious.

In general, you can overclock the processor in two ways - manually through the BIOS and using special programs. These methods are equally easy to use, but there are people who are afraid to go into the BIOS, so we will tell you how to overclock the processor in both ways.

Also, do not forget that insufficient power supply unit power can prevent processor overclocking. It is better to take a power supply unit with a small power reserve when buying a computer. This will allow you to painlessly upgrade your hardware, and also, as in today's topic, will provide an opportunity for overclocking.

Overclocking the processor via BIOS

First of all, I will tell you how to overclock the processor through BIOS. On our website, we have already repeatedly told how you can go to the BIOS settings. It depends on the manufacturer of your computer's motherboard. When turning on (or restarting) the computer, even before the operating system starts loading, you need to press key to enter BIOS settings. You can find out which key to press from the prompt when you turn on the computer or in the instructions (documentation) of your motherboard. Most often these are keys: Del , F2 or F8 but there may be others.

How to overclock a processor via BIOS

After you get into the BIOS, you need to go to the Advanced tab. Next, I will tell you on the example of my computer, but everything should be very similar for you. Although, of course, there will be differences. This is due to different BIOS versions and different processor settings available. Perhaps this tab will be called, for example, CPU Configuration or something else. You need to wander through the BIOS and understand which section you have is responsible for configuring the central processor.

How to overclock a processor via BIOS

Overclock Tunner by default is in position Auto ... Move it to position Manual in order for you to access additional manual settings for the processor.

After that, note that you will have the FSB Frequency item, in which you can adjust the base frequency of the processor bus. In fact, this frequency multiplied by the CPU Ratio gives us the full frequency of your processor. That is, an increase in frequency can be achieved either by increasing the bus frequency, or by increasing the multiplier value.

Is it better to increase the bus frequency or a multiplier?

A very topical question for beginners. Let's start with the fact that not on all processors you will be able to increase the multiplier value. There are processors with a locked multiplier, and there are processors with an unlocked one. For Intel processors, processors with an unlocked multiplier can be identified by the suffix “ K" or " X"At the end of the processor name, as well as the Extreme Edition series, and AMD has the suffix" Fx »And the Black Edition series. But it is best to carefully look at the detailed characteristics, because there are always exceptions. Please note that the entire line of Intel Core i9 processors has an open multiplier.

If possible it is best to overclock the processor by increasing the multiplier value ... It will be safer for the system. But overclocking the processor by increasing the bus frequency is highly discouraged, especially for overclocking beginners. Why? Because by changing this indicator, you not only overclock the central processor, but also affect the characteristics of other components of the computer, and often these changes can get out of control and harm your computer. But if you are aware of your actions, then everything is in your hands.

Stages of overclocking the processor through BIOS

In principle, there is nothing complicated about this. But you need to do everything slowly and carefully. So, for example, if you are planning to overclock your processor to the maximum, then you should not increase the processor frequency by 500 MHz at once, increase gradually, first by 150 MHz, conducted a stress test, made sure that everything is working stably. Then raise the frequency by another 150-100 MHz and so on. Toward the end, it is better to reduce the step to 25-50 MHz.

When you reach the frequency at which the computer cannot cope with the stress test, go to the BIOS and return the frequencies to the last successful stage. For example, at a frequency of 3700 MHz the computer passed the stress test successfully, but at a frequency of 3750 MHz it has already failed the test, which means that its maximum possible operating frequency will be 3700 MHz.

Of course, you can still go through various specific tests and identify the "weak link" (power supply or cooling system), but why do we need these extremes, right?

Overclocking the processor with special programs

In general, I would recommend overclocking the processor in BIOS manually, but if the BIOS environment is alien to you, then you can use special programs to overclock the processor. There are many such programs. Some of them are more suitable for INTEL processors, while others are more suitable for AMD processors. Although the principle of operation is almost identical. So let's find out how to overclock a processor using special programs .

How to overclock a processor using SetFSB

Utility SetFSB designed for overclocking the processor over the bus. This is clear from the name. The developers are proud that SetFSB is lightweight and perfectly fulfills all its functions.

IMPORTANT INFORMATION!!! I downloaded the program from the "official site" and from the SOFTPORTAL portal. The contents of the archives are very different. If the archive on the softportal weighs less than 200 KB and has instructions for its use in addition to the utility, then on the "official site" the archive contains another archive containing a suspicious .exe file weighing more than 5 MB and there are no additional instructions. When the file starts, Windows says that the license is verified, but the license belongs to some Ukrainian shipbuilding company, judging by the name "SUDNOBUDUVANNYA TA REMONT, TOV". I decided to cancel the installation.

Download the program from the SOFTPORTAL site, not from the official one. Apparently the official website is fake.

So, before entering the program, it is highly recommended to check the list of motherboards with which this utility works. This list is in the file setfsb.txt ... If you find your motherboard, continue. If not, then you are at great risk by continuing to use this utility.

How to overclock a processor using SetFSB

When starting SetFSB, you will need to enter a temporary ID in the required field. Just retype the name of the little box in the box in it. Why is this? The creators assume that if you have not read the instructions, then you will not be able to go beyond this window and go to read the instructions to find out what you need to enter into it, and at the same time read other useful information that can prevent damage to your processor (and motherboard).

How to overclock a processor using SetFSB

Next, the most difficult thing is to choose your parameter Clock Generator ... To find out, you need to disassemble the computer and carefully examine the motherboard in search of a chip with a name starting with the letters " ICS ". There may be other letters, but these are found in 95% of cases.

When you do this, click on the Get FSB button and the sliders will be unlocked. And you will need to move the first slider to the right quite a bit, each time pressing the SET FSB button, so that example = thread the changed parameters. And you will have to do so until then, until you reach the desired characteristics of the processor frequency. If you overdo it, the computer will freeze and you will have to start all over again.

Overclocking the CPU with CPUFSB

Utility CPUFSB not much different in functionality from the SetFSB just reviewed. However, there is something to praise her for. The first and rather significant plus is that the utility is completely Russified, which is very convenient, you must agree. The program is more tailored for Intel processors, but it can also be applied to AMD processors.

How to overclock a processor using cpufsb

To overclock the processor in the CPUFSB program, you will need to sequentially:

  1. Specify the necessary information about your motherboard and the type of clock (Clock Generator).
  2. Then click on " Take frequency ".
  3. Move the slider to the right to change the frequency of the sample.
  4. At the end, click on “ Set frequency ".

There is nothing complicated. You can intuitively figure out the settings even without prompts.

Other programs for overclocking the processor

We have considered in more or less detail the most frequently used programs that are used to overclock the processor. However, the list of programs does not end there. But we will not describe them in detail, because the principle of their operation is similar to the previous ones. Here is a small list of overclocking programs that you can use if the first ones did not suit you or you could not download them.

  1. Over drive
  2. Clockgen
  3. ThrottleStop
  4. SoftFSB
  5. CPUCool

Output

Now you know how to overclock the processor, or maybe you even tried to do it yourself while reading the article. I hope everything went well for you and without any unpleasant consequences. Remember the golden rule - Better tit in hand than pie in the sky ! Therefore, do not overclock, otherwise you will have to buy a new processor, and maybe even a motherboard.

We always write about overclocking: our articles, news, thoughts - everything is about overclocking. The site has a "Reference" section where there is general information about overclocking and we publish many articles from which you can learn the details and features of overclocking on specific systems. In fact, this is quite enough to get into overclocking for the first time, and everything else will come with experience. However, I can well imagine the confusion of a newbie, in front of whom lies an ocean of information, and he simply does not know where to start. It's good when there is a more experienced friend nearby who can explain and suggest, but if not? In this case, even such an elementary operation as entering the BIOS is comparable to a feat for a beginner. In my mail, the number of letters that ask to show "which buttons to poke on" in order to overclock the processor does not decrease. Today's article is about buttons.

Of course, the thoughtless "push-button" approach to overclocking is fundamentally wrong. Before you press, you need to understand what you are pressing for and what consequences your actions can lead to. And although the danger of overclocking is greatly exaggerated, nothing is impossible and there is a very real possibility of disabling your computer. Therefore, it is customary to precede articles of this kind with long introductions, in which it is supposed to list all the dangers and warn the user about responsibility. However, long boring introductions still skip everything, and I believe that reasonable people read us, so we will do without prefaces, we will assume that I warned you.

So, today it is extremely easy to overclock a processor, for this you just need to increase the frequency at which it operates. There are many programs with which you can overclock directly from Windows, for example, ClockGen.

There are several different versions of the utility, designed for different motherboards and chipsets. In addition, many motherboard manufacturers offer their own overclocking utilities like Gigabyte's EasyTune5 ...

... or MSI's CoreCenter:

Such programs can be found on the driver CD that comes with the motherboard, and updated versions are easy to download from the motherboard manufacturer's website. Can I use these or similar utilities? Of course it is possible, sometimes this is the only way to decently overclock the processor if the motherboard has limited overclocking capabilities from the BIOS. However, despite the seeming simplicity and convenience of such overclocking, I prefer not to use such utilities, and there are several reasons for this. First of all, any program is not free from errors, but why do we need extra problems? Overclocking from BIOS allows you to overclock the processor immediately after starting, and programs will start working only after starting Windows. In addition, the very procedure of starting a computer and then loading Windows can serve as a preliminary test for the stability of an overclocked processor. In general, if you want to overclock with the help of programs, then I don't think that you will have serious difficulties: you can first read the description of the program on the manufacturer's website or in the manual for the motherboard, but today we are only considering overclocking from the BIOS.

How to get there? To do this, when starting the computer, it is usually enough to press the "Delete" key, you can do this several times so as not to miss. Do not hesitate to read the inscriptions that appear on the screen, as well as pre-scroll through the manual for the board, because sometimes a different key or a combination of them is used to enter the BIOS, and to access all the options on Gigabyte motherboards, for example, after entering the BIOS, you need press Ctrl-F1. As a result, you should see something like this:

Do not be afraid of the abundance of unfamiliar words, despite the difference in BIOS versions, as well as the fact that the same options can be called differently, we can easily find what we need.

To overclock, we need to increase the processor frequency, which is the product of the multiplier and the bus frequency. For example, the nominal frequency of the Intel Celeron D 310 processor is 2.13 GHz, its multiplier is x16, and the bus frequency is 133 MHz (133.3x16 = 2133 MHz). This means that we need to increase either the multiplier, or the bus frequency (FSB), or both parameters at the same time. Modern Intel processors do not allow changing the multiplier (some older models can reduce it to x14 using energy saving technologies), some AMD processors can do this, but first, let's consider the general case - overclocking by increasing the bus frequency, especially since this way allows more increase overall system performance.

Why? Because a lot of things are interconnected and synchronized in a computer. For example, by increasing the frequency of the processor bus, we simultaneously increase the frequency of the memory, the speed of data exchange increases, and due to this, the performance additionally rises. True, there is also a downside here, because by overclocking the processor and memory at the same time, we can stop ahead of time. It often turns out that the processor is still capable of further overclocking, but the memory is gone. Currently, only motherboards based on the NVIDIA nForce4 SLI Intel Edition chipset are able to overclock the processor regardless of memory, there are very few such motherboards so far, which means, most likely, you have something different. Therefore, before overclocking the processor, we need to take care in advance that we are not limited by memory or something else.

We are looking for an option in the BIOS, which is responsible for the memory frequency. It can be in different sections and have different names, so it's a good idea to check this in the manual for the motherboard beforehand. Most often this option is found in two sections: either related to overclocking and memory timings, or to processor overclocking. The first one can be called Advanced Chipset Features or simply Advanced, like in ASUS. Here the parameter is called Memclock index value and is measured in megahertz:

Or it can be located in the POWER BIOS Features section, like in EPoX, called System Memory Frequency or simply Memory Frequency and designate the memory frequency as DDR400, DDR333 or DDR266, or maybe PC100 or PC133.

For us, all this does not play the slightest role, our task is to find this parameter and set the minimum value for it. The choice of the desired value can take place in different ways, which depend on the BIOS version and manufacturer. You can, for example, press Enter and select the required value from the list that appears using the arrows on the keyboard, and sometimes you can cycle through the values ​​using the Page Up, Page Down, "+" or "-" keys.

Why do we set the minimum memory frequency, because it is, most likely, not so weak and capable of more? When overclocking the processor, we will increase the FSB frequency, the memory frequency will also rise, but there is a hope that increasing from the minimum possible value, and not from the nominal value, it will remain within the acceptable limits for our memory and will not limit processor overclocking. To be sure, you can set more timings for the memory than those that are set by default.

First, it will push the limit of stable performance even further for our memory. Secondly, when automatically setting the timings, it is possible that the motherboard mistakenly sets too low, inoperative values, and so we can be sure that guaranteed working timings are set for the memory. To make sure of this, you need to remember to save the changes in the BIOS and restart. To do this, select the Save & Exit Setup parameter or press F10 and confirm the seriousness of our intentions by pressing the Enter or "Y" (Yes) key in older BIOS versions.

In most cases, setting the memory to a low frequency is enough and you can start overclocking the processor right away, but we will not rush and make sure that nothing stands in our way.

When I said that many things are interconnected in a computer, I did not mention that simultaneously with the processor bus frequency, not only the memory frequency increases, but also other frequencies, for example, on PCI, Serial ATA, PCI-E or AGP buses. In small limits, this is even good, since it slightly speeds up the system, but if the frequencies are significantly exceeded above the nominal, the computer may refuse to work. The nominal frequencies of the PCI bus are 33.3 MHz, AGP - 66.6 MHz, SATA and PCI Express - 100 MHz. Almost all modern chipsets are able to fix the frequencies at the nominal values, but just in case it is better to make sure of this yourself. To do this, you need to find a parameter, which is usually called AGP / PCI Clock, and select a value of 66/33 MHz for it.

The above is true for Intel chipsets designed for Pentium 4 processors, as well as for NVIDIA chipsets and the latest SiS chipsets, but this is not the case for early Intel, SiS and VIA chipsets, right up to the very latest. They do not know how to fix frequencies at the nominal value. In practice, this means that if your motherboard is based on the VIA K8T800 chipset, for example, you will hardly be able to exceed the FSB frequency of 225 MHz during overclocking. Even if your processor is capable of more, you will have to stop due to the fact that hard drives will no longer be detected or the sound card integrated on the board will refuse to work. However, you can try and we'll talk about this later.

For NVIDIA chipsets designed for AMD processors with Socket 754/939, the frequency of the HyperTransport bus is of great importance. By default, it is equal to 1000 or 800 MHz, it is advisable to reduce it before overclocking. Sometimes its real frequency is written, but more often a multiplier of x5 is used for a frequency of 1000 MHz and x4 for 800 MHz.

The parameter can be called HyperTransport Frequency, or HT Frequency, or LDT Frequency. You need to find it and reduce the frequency to 400 or 600 MHz (x2 or x3).

So, we reduced the memory and HyperTransport bus frequencies, fixed the PCI and AGP bus frequencies at the nominal, and it's time to start overclocking the processor. To do this, we need to find the Frequency / Voltage Control ...

... which EPoX may call POWER BIOS Features ...

... for ASUS - JumperFree Configuration ...

... and ABIT's name is μGuru Utility:

The difference in names will not hurt us, we are looking for the item CPU Host Frequency, or CPU / Clock Speed, or External Clock, or a parameter with another similar name that controls the FSB frequency. We will change it upwards.

How much to increase? I do not know. Much depends on your processor, motherboard, cooling system, and power supply. Start small, try increasing the frequency from the nominal by 10 MHz - in most cases it should work. Do not forget to save the changed parameters, boot into Windows, make sure that the processor is actually overclocked using a utility like CPU-Z, and check the stability of the overclocked processor in some program (Super PI, Prime95, S&M) or a game. Of course, you first need to make sure that this program or game works perfectly stable with an overclocked processor. Do not forget to control the processor temperature, it is highly undesirable to exceed 60 ° Celsius, but the lower it is, the better.

Owners of Intel Pentium 4 and Celeron processors based on them should definitely use ThrottleWatch, RightMark CPU Clock Utility, or something similar. The fact is that when overheated, these processors can run into throttling, which is reflected in a noticeable decrease in performance. "Overclocking" with throttling does not make sense, since the speed can drop even below those values ​​that the processor produces in the nominal mode. Utilities will be able to warn about the beginning of throttling, which means that you will need to take care of better cooling or reduce overclocking.

If everything went well, then you can slightly increase the frequency and so on until the system remains stable. As soon as the first signs of overclocking appear: freezes, program crashes, errors, blue screens or the temperature rises too high - you need to reduce the frequency and again make sure that the system is working stably under the new conditions.

Often the results published in our CPU Overclocking Statistics will help you navigate. You can roughly estimate to what frequencies your processor is capable of overclocking. Just be careful, do not forget that not only the name of the processor matters, but also the type of kernel on which it is based and even its revision. In addition, even processors from the same batch have different overclocking potential, so do not rush to set the maximum frequency from what you have seen, it is safer and more reliable to gradually rise from lower to higher.

However, exceptions are possible. Remember when I talked about old chipsets that cannot fix AGP and PCI frequencies at nominal? This is so, they really cannot support the nominal frequencies of these buses in the entire FSB frequency range, but they must keep them nominal at the standard frequencies for processors. And they do it with dividers that switch automatically depending on the set FSB frequency. The standard frequencies are 100, 133, 166 and 200 MHz.

Suppose that when the Duron processor was overclocked from 100 to 120 MHz on the bus, it showed iron stability, and when the FSB was increased to 125 MHz, the system began to glitch or refused to start at all. It is quite possible that the processor overclocking limit has been reached, but it may well be that the limit is still far away, and we are hindered by the increased frequencies on the AGP and PCI buses. It's very easy to check - you just need to set the frequency to 133 MHz. In this case, the motherboard uses other dividers, which will set the nominal bus frequencies. If your processor is capable of such overclocking, then you can go even higher.

Do I need to increase the voltage supplied to the processor? Sometimes it can really help to move further, but not always. But this always dramatically increases heat dissipation, which already grows with overclocking, so I would not recommend starting with a rash increase in voltage. However, the computer is yours and if you don’t feel sorry for it, do what you want. Only then don't complain.

As for changing the processor multiplier, AMD processors with Socket A (462), released before the 40th week of 2003, AMD Athlon FX processors have a free multiplier, and AMD processors with Socket 754/939 (except for the younger Semprons) can reduce his. Changing the multiplier allows you to overclock more flexibly. For example, if you have an old motherboard that does not know how to fix AGP and PCI frequencies, then you can overclock only by increasing the multiplier, and not with the bus, in this case the frequencies will remain at their nominal value. Another situation is possible: if you have a processor with a sufficiently high multiplier, then it can be reduced to overclock it more on the bus, because this promises some "free" performance gain. Some AMD Socket A processors have a locked multiplier, but they can be unlocked or turned into mobile ones, which will also open up access to changing the multiplier. In this article I cannot tell you about everything, there are several works on this topic on our website, information is available in the conference - you will find it if you need it.

But what if the system is overclocked, incorrect parameters are set and the board does not even start, or does it start up and soon freezes? A number of modern motherboards monitor the startup process and if it is interrupted, the board automatically restarts, setting the nominal values ​​for the processor and memory. You just have to enter the BIOS again and correct your mistake.

Sometimes it helps to start with the Insert key pressed, in this case the board also resets the parameters to the nominal, which contributes to a successful start. If all else fails, then you need to find the Clear CMOS jumper on the board, with the power off, switch it to two adjacent contacts for three seconds and put it back in place. In this case, absolutely all parameters are reset to their nominal value. Next time, be moderate in your appetites.

So, the processor is successfully overclocked, but your work is not finished yet, because the system performance depends not only on the processor frequency. Have you forgotten that at the very beginning we reduced the memory frequency? Now it's time to raise it, find the optimal timings. Only experiments and advice from friends will help in this, not always a high frequency guarantees high performance. Change the parameters one at a time and immediately test the resulting changes. If you play games, the next step is to overclock your video card.

As you can imagine, it is impossible to tell everything in one article. There are many nuances, but there is nothing difficult in overclocking and, over time, you will figure it out. Our articles, study of conference materials, advice from friends will help. Feel free to ask and use the search. Most likely, the answer to your seemingly insoluble question has already been found by someone else. Before you overclock at random, think about it, because an overclocked, but working computer, much better than overclocked to complete inoperability. The main thing is to act deliberately, gradually, and you will succeed.

If you are not satisfied with the speed of the PC, then upgrade it. First of all, a more modern processor is installed. But this is not the only way. You can get a more powerful computer without replacing its components, without spending money. To do this, the processor is overclocked, which means in slang - "overclocking". How to overclock the processor through BIOS, we will tell in our article.

Why overclocking is possible

Machine power depends on the number of operations performed per unit of time. It is set by the clock frequency, the higher it is, the greater the performance. Therefore, the progress of computer technology was accompanied by a constant increase in this characteristic. If in the first computers, assembled on relays and lamps, it was several hertz, today the frequency is measured already in gigahertz (10 9 Hz).

The default value, which is automatically set by the generator on the motherboard, is set by the manufacturer for this processor model. But this does not mean that it cannot work faster. There is always a 20-30 percent reinsurance, so that all microcircuits in the batch work stably even in adverse conditions. The frequency can be raised, and this is done in hardware, without making changes to the electrical circuit.

What, apart from the speed of work, changes during acceleration

More intense work requires more energy. Therefore, when overclocking the laptop processor, it is worth considering that the battery will drain faster. For desktop machines, you need a power reserve. The heating of the microcircuit also increases, therefore, when deciding to overclock, make sure that a powerful cooling system is installed, the standard cooler of your computer may not cope with the increased temperature.

From the above, we can conclude that a more powerful power supply and cooling system will be required, it is necessary to control the temperature and stability of the equipment.

Is overclocking dangerous

Early BIOS and processor models did not include temperature control. Overclocking the machine too much could burn the processor, so few took the risk. Today, such a probability is small, if overheating occurs, then the system itself switches to standard clock frequencies.

Overclocking using programs and through BIOS, which is better

Overclocking the processor can be done in two ways:

  • Using programs or utilities. They can be easily downloaded from the Internet and often come with a motherboard driver disc. This method is a little simpler, but not without its drawbacks. The speed increase does not start until Windows starts. The program itself takes up the processor resource, albeit insignificantly.
  • Overclocking through BIOS. In this case, you will have to deal with the settings, and, as a rule, the BIOS menu is not Russified. But the system increases performance immediately after switching on. In addition, a running operating system is an excellent test of stability. If something is wrong, then it is better to moderate your appetite and slow down.

How to enter BIOS

We will try at least this is a little difficult, since the BIOS versions differ for different motherboards, give the most detailed instructions:

  1. It is required to enter the BIOS. To do this, when you start the machine, press Delete, usually to get to the right moment, you need to repeat this action quickly several times. If it doesn't work, then try the combination Ctl + F1. It should work.
  2. It is not the Windows boot splash screen that is displayed, but a menu with several columns and inscriptions in English or very rarely in Russian. This means that the BIOS has loaded. You can put the mouse aside and forget about the touchpad. They do not work now. Moving between items is done with the help of arrows, confirmation of the selection - with the "Enter" key, cancellation - ESC. To save the entered parameters in the BIOS at the end of the manipulations, it is necessary to select the item " Save & Exit »(Save and exit) or press F10.
  3. You start to conjure with parameters. There are two ways to choose - increase the bus frequency and increase the multiplier.

Overclocking by raising the bus frequency

This way is more profitable. It is also the only method for Intel processors that do not support upward multiplier adjustments. At the same time, not only the processor is overclocked, but also the rest of the system components. But there is one thing, but not always the RAM can work at an increased frequency, and the operation of the machine will be disrupted not due to the fact that the processor is not stable at an increased frequency, but due to a memory failure. True, many motherboards also allow you to adjust the clock speed of the RAM.

Now in more detail what to do:

  1. Find the item " CPU Clock "Or" CPU Frequency "," FSB Frequency "," Frequency BCLK "," External Clock "(It's all the same) and there you increase the frequency. At the same time, do not rush, do it gradually, in steps of about 3-5%. After each step, check the stability and temperature of the processor. It is undesirable for it to heat up to more than 70 degrees. To control the temperature, you can use the utility SpeedFun or the like. Thus, find the optimum value for the bus frequency.
  2. If overclocking does not work due to memory problems, then try setting a lower clock frequency for it. Find the menu item responsible for this parameter in the sections " Advanced "(" Advanced Chipset Features ") or " Power BIOS Features ". It will be called “ Memclock index value " or " System Memory Frequency ". Set it lower than the default value, you can generally reset it to a minimum, since as the bus frequency increases, so does it. Then again you repeat all the bus overclocking operations, achieving fast and stable computer operation.

Multiplier overclocking

The processor operating frequency is a multiple of the bus frequency. This parameter is set by hardware multiplier. For example, the bus operates at 133.3 MHz, and the processor at 2.13 GHz - the frequency factor is 16. Changing the frequency factor to 17, we get 133.3 * 17 = 2266 - 2.26 GHz - the operating frequency of the processor. By changing the multiplicity, we do not touch the bus, so only the processor is overclocked, all other elements of the system work stably, just like before overclocking. Overclocking the processor through the BIOS using this method somewhat limits the frequency range that can be set, but this is not critical.

In order to perform this operation, you need to find this parameter in the BIOS settings. His signatures are different - " CPU Clock Multiplier "," Multiplier factor "," CPU Ratio "," CPU Frequency Ratio "," Ratio CMOS Setting ". Similarly, we increase this parameter and look at the stability of operation and temperature. It is not necessary to conjure with the frequency of the RAM. It's a pity that this method does not work for all processors.

How to cancel overclocking

If something went wrong, then you can reset the BIOS settings through the menu item " Load Optimized Default ". If, due to the settings, the BIOS itself has stopped loading, then you can exit to standard mode using the following operations:

  1. Hold down the Insert key while turning on the computer.
  2. Take out the battery on the motherboard for a few minutes, then replace it.
  3. Find the contacts bridged by the chip (jumper), which are signed by Clear CMOS. Remove the jumper and connect two adjacent pins with it. The operation is performed with the power off.

What else needs to be considered when overclocking

Let's talk more about small overclocking nuances:

  • Almost always, during overclocking, you can improve the stability of the processor by raising its supply voltage. This can be done in the menu item " CPU Voltage "," VCORE Voltage "," CPU Core ". But at the same time be sure to control the temperature and proceed in small steps no more than a thousandth of a volt.
  • When the processors overheat, they, as a rule, are done to protect them, enter the throttling mode with minimal parameters. The system will be stable, but slow. therefore you cannot cross this threshold otherwise, why overclock.

Conclusion

This article talks about overclocking the processor, which can be done in two ways: through the BIOS or using special utilities, about which read our article on programs for overclocking the processor. More attention was paid to overclocking via BIOS, increasing the bus frequency or multiplier. This should be done gradually. It is necessary to monitor the temperature of the processor and check its stability. That's all we wanted to tell you about overclocking. We hope our article will help you increase the performance of your system.

By the term "overclocking" most users mean exactly increasing the performance of the central processor. In modern models of motherboards, this procedure can also be carried out from under the operating system, but the most reliable and universal method is setting through the BIOS. It is about him that we want to talk today.

Overclocking the CPU through BIOS

Before starting the description of the techniques, we will make several important notes.

  • Processor overclocking is supported in special motherboards: designed for enthusiasts or gamers, so budget motherboards often lack such options, just like in laptop BIOS.
  • Overclocking also increases the percentage of heat generated, therefore it is strongly recommended to install serious cooling before increasing the operating frequency and / or voltage.

See also: Making high-quality processor cooling

  • Some CPU models do not provide overclocking, which is why even changing the firmware settings has no effect. This statement is true for budget decisions.
  • The actual BIOS setup begins with entering the interface shell. If you do not know how this is done on your device, use the guide on the link below.

    Attention! All further actions you take at your own peril and risk!

    Text BIOS

    Even with the popularity of the UEFI solution, many manufacturers still use the text interface option.

    AMI For a long time, solutions from American Megatrends provided a wide range of processor overclocking functionality.

      Enter the firmware interface, then go to the tab "Advanced" ... Use the option "CPU Configuration" .

    After that go to parameter "Ratio CMOS Setting" ... The numerical value in this option is the multiplier used by the processor when setting the frequency. Accordingly, a higher multiplier should be selected for better performance.

    Next, go to item "CPU Frequency" ... Here you set the minimum value from which the above multiplier works. In some cases, the frequency can be manually preset, but in most solutions, fixed values ​​are available. The ratio is also clear: the higher the minimum frequency, the higher the maximum, taking into account the multiplier.

    It will also be useful to configure the power supply - go to step "Chipset Configuration" .

    Go to voltage options - memory, processor and power. There are no universal values, and you need to set them based on the specifications and capabilities of the components.

  • After making changes, go to the tab "Exit" where use clause Save Changes & Exit .
  • Award

      After entering BIOS, go to the section MB Intelligent Tweaker and open it.

    As in the case of the AMI BIOS, it is worth starting overclocking by setting the multiplier, paragraph "CPU Clock Ratio" ... The BIOS under consideration is more convenient in that next to the multiplier it indicates the actually received frequency.

    To set the start frequency of the multiplier, switch the option "CPU Host Clock Control" into position "Manual" . Next, use the setting "CPU Frequency (MHz)" - select it and press Enter. Write down the desired starting frequency. Again, it depends on the processor specifications and the capabilities of the motherboard.

    Additional voltage configuration is usually not required, but this parameter can also be adjusted if necessary. To unlock these options, switch "System Voltage Control" in position "Manual" . Set the voltage separately for processor, memory and system buses.

  • After making changes, press the key F10 on your keyboard to bring up the save dialog, then press Yto confirm.
  • Phoenix This type of firmware is most often found in the form of a Phoenix-Award, since the Phoenix brand has been owned by the Award company for many years. Therefore, the settings in this case are very similar to the one mentioned above.

      When entering the BIOS, use the option "Frequency / Voltage Control" .

    First of all, set the required multiplier (the available values ​​depend on the CPU capabilities).

    Next, set the starting frequency by entering the desired value in the option "CPU Host Frequency" .

    If necessary, adjust the voltage - the settings are inside the submenu "Voltage Control" .

  • After making changes, leave BIOS - press the keys F10 then Y.
  • We draw your attention - often the options mentioned can be located in different places or have a different name - it depends on the manufacturer of the motherboard.

    UEFI graphic interfaces

    A more modern and widespread version of the firmware shell is a graphical interface, which can also be interacted with using a mouse.

    ASRock

      Call BIOS, then go to the tab OC Tweaker .

    Find the parameter "CPU Ratio" and switch it to mode "All Core" .

    Then in the field "All Core" enter the desired multiplier - the larger the entered number, the higher the resulting frequency will be. Parameter "CPU Cache Ratio" should be set to a multiple of "All Core" : for example 35 if the base value is 40.

    The base frequency for multiplier operation should be set in the field "BCLK Frequency" .

    To change the voltage, if necessary, scroll the parameter list to the option "CPU Vcore Voltage Mode" to be switched to "Override" . After this manipulation, the custom settings for processor consumption will become available.

  • Saving parameters is available when exiting the shell - you can do this either using the tab "Exit" , or by pressing the key F10 .
  • ASUS

      Overclocking options are only available in advanced mode - switch to it with F7 .

    Move to the tab "AI Tweaker" .

    Toggle the parameter AI Overclock Tuner into mode "XMP" ... Make sure the function "CPU Core Ratio" is in position "Sync All Cores" .

    Adjust the frequency multiplier in the line "1-Core Ratio Limit" according to the parameters of your processor. The starting frequency is adjusted in line "BCLK Frequency" .

    Also set the coefficient in the parameter "Min. CPU Cache Ratio " - as a rule, it should be below the multiplier per core.

    Voltage settings are in the submenu Internal CPU Power Management .

  • After making all the changes, use the tab "Exit" and paragraph Save & Reset to save the parameters.
  • Gigabyte

      As in the case with other graphical shells, in the interface from Gigabyte you need to switch to the advanced control mode, which is called here "Classic" ... This mode is available by the main menu button or by pressing the key F2 .

    Next, go to the section "M.I.T." , in which we are primarily interested in the block "Advanced Frequency Settings" , open it.

    First of all, select a profile in the parameter "Extreme Memory Profile" .

    Next, select a multiplier - enter the number suitable for the specifications in the paragraph "CPU Clock Ratio" ... You can also set the base frequency value, option "CPU Clock Control" .

    Voltage settings are in the block "Advanced Voltage Control" tabs "M.I.T." . Change the values ​​to suit the chipset and processor.

  • Click on F10 to call the dialog for saving the entered parameters.
  • MSI

      Press the key F7 to switch to advanced mode. Then use the button "OC" to access the overclocking section.

    The first parameter that should be adjusted for overclocking is the base frequency. The option is responsible for this. "CPU Base Clock (MHz)" , enter the desired value into it.

    Next, select the multiplier and enter it in the line "Adjust CPU Ratio" .

    Make sure the parameter "CPU Ratio Mode" is in position "Fixed Mode" .

    The voltage parameters are located below the list.

  • After making changes, open the block "Setting" in which select the option Save & Exit ... Confirm the exit.
  • Conclusion

    We reviewed the methodology for overclocking the processor through the BIOS for the main shell options. As you can see, the procedure itself is simple, but all the required values ​​must be known exactly to the last digit.

    Thank the author, share the article on social networks.

    Good day! After you have learned what overclocking is, it would be logical to dwell on the question in more detail, how to overclock the processor and what is it all about CPU overclocking ... And very soon you will learn how to overclock your RAM. Yes, you can do that too! And we finally have an article about overclocking a video card.

    Additional utilities for overclocking the processor

    First of all, in order to overclock the processor, you need a small set of utilities that will help you monitor the state of your system and its stability, as well as the temperature of the processor. Below we list a list of utilities and programs and briefly describe what they are responsible for.

    CPU-Z - a small but very useful utility that will show all the basic technical information of your CPU. Useful for tracking frequencies and voltages. Free.

    CoreTemp - another free utility, somewhat similar to CPU-Z, but does not go deep into technical indicators, but displays the temperature of the processor cores and their load.

    Speccy - shows detailed technical information not only about the processor, but also about the entire computer as a whole. There is also information about the temperatures of various components of the system.

    LinX - a free program that we need to test the stability of the system after each stage of increasing processor performance. It is one of the best stress test software. It loads the processor at 100%, so do not be alarmed, sometimes it may seem that the computer is frozen.

    Overclocking the processor

    Before learning how to overclock a processor, I highly recommend stress-testing your computer in a non-overclocked state (for example, with the program FurMark ). This is necessary in order to determine the approximate potential for overclocking and generally check the system for errors.

    If in the non-overclocked state the test gives any errors or the temperature during testing is prohibitively high, then it is better to finish your "overclocking" at this point.

    If everything works stably and the processor temperature is normal, then we can continue. And you better note for yourself the key characteristics of an overclocked system, such as minimum CPU temperature, maximum CPU temperature, voltage, etc. Better yet, take a screenshot of the screen or take a picture on your phone so that you have detailed information at hand, just in case. This is necessary to analyze the deviations of indicators from the nominal. Not critically important, but very useful and curious.

    In general, you can overclock the processor in two ways - manually through the BIOS and using special programs. These methods are equally easy to use, but there are people who are afraid to go into the BIOS, so we will tell you how to overclock the processor in both ways.

    Also, do not forget that insufficient power supply unit power can prevent processor overclocking. It is better to take a power supply unit with a small power reserve when buying a computer. This will allow you to painlessly upgrade your hardware, and also, as in today's topic, will provide an opportunity for overclocking.

    Overclocking the processor via BIOS

    First of all, I will tell you how to overclock the processor through BIOS. On our website, we have already repeatedly told how you can go to the BIOS settings. It depends on the manufacturer of your computer's motherboard. When turning on (or restarting) the computer, even before the operating system starts loading, you need to press key to enter BIOS settings. You can find out which key to press from the prompt when you turn on the computer or in the instructions (documentation) of your motherboard. Most often these are keys: Del , F2 or F8 but there may be others.

    After you get into the BIOS, you need to go to the Advanced tab. Next, I will tell you on the example of my computer, but everything should be very similar for you. Although, of course, there will be differences. This is due to different BIOS versions and different processor settings available. Perhaps this tab will be called, for example, CPU Configuration or something else. You need to wander through the BIOS and understand which section you have is responsible for configuring the central processor.

    Overclock Tunner by default is in position Auto ... Move it to position Manual in order for you to access additional manual settings for the processor.

    After that, note that you will have the FSB Frequency item, in which you can adjust the base frequency of the processor bus. In fact, this frequency multiplied by the CPU Ratio gives us the full frequency of your processor. That is, an increase in frequency can be achieved either by increasing the bus frequency, or by increasing the multiplier value.

    Is it better to increase the bus frequency or a multiplier?

    A very topical question for beginners. Let's start with the fact that not on all processors you will be able to increase the multiplier value. There are processors with a locked multiplier, and there are processors with an unlocked one. For Intel processors, processors with an unlocked multiplier can be identified by the suffix “ K" or " X"At the end of the processor name, as well as the Extreme Edition series, and AMD has the suffix" Fx »And the Black Edition series. But it is best to carefully look at the detailed characteristics, because there are always exceptions. Please note that the entire line of Intel Core i9 processors has an open multiplier.

    If possible it is best to overclock the processor by increasing the multiplier value ... It will be safer for the system. But overclocking the processor by increasing the bus frequency is highly discouraged, especially for overclocking beginners. Why? Because by changing this indicator, you not only overclock the central processor, but also affect the characteristics of other components of the computer, and often these changes can get out of control and harm your computer. But if you are aware of your actions, then everything is in your hands.

    Stages of overclocking the processor through BIOS

    In principle, there is nothing complicated about this. But you need to do everything slowly and carefully. So, for example, if you are planning to overclock your processor to the maximum, then you should not increase the processor frequency by 500 MHz at once, increase gradually, first by 150 MHz, conducted a stress test, made sure that everything is working stably. Then raise the frequency by another 150-100 MHz and so on. Toward the end, it is better to reduce the step to 25-50 MHz.

    When you reach the frequency at which the computer cannot cope with the stress test, go to the BIOS and return the frequencies to the last successful stage. For example, at a frequency of 3700 MHz the computer passed the stress test successfully, but at a frequency of 3750 MHz it has already failed the test, which means that its maximum possible operating frequency will be 3700 MHz.

    Of course, you can still go through various specific tests and identify the "weak link" (power supply or cooling system), but why do we need these extremes, right?

    Overclocking the processor with special programs

    In general, I would recommend overclocking the processor in BIOS manually, but if the BIOS environment is alien to you, then you can use special programs to overclock the processor. There are many such programs. Some of them are more suitable for INTEL processors, while others are more suitable for AMD processors. Although the principle of operation is almost identical. So let's find out how to overclock a processor using special programs .

    How to overclock a processor using SetFSB

    Utility SetFSB designed for overclocking the processor over the bus. This is clear from the name. The developers are proud that SetFSB is lightweight and perfectly fulfills all its functions.

    Download the program from the SOFTPORTAL site, not from the official one. Apparently the official website is fake.

    So, before entering the program, it is highly recommended to check the list of motherboards with which this utility works. This list is in the file setfsb.txt ... If you find your motherboard, continue. If not, then you are at great risk by continuing to use this utility.

    When starting SetFSB, you will need to enter a temporary ID in the required field. Just retype the name of the little box in the box in it. Why is this? The creators assume that if you have not read the instructions, then you will not be able to go beyond this window and go to read the instructions to find out what you need to enter into it, and at the same time read other useful information that can prevent damage to your processor (and motherboard).

    Next, the most difficult thing is to choose your parameter Clock Generator ... To find out, you need to disassemble the computer and carefully examine the motherboard in search of a chip with a name starting with the letters " ICS ". There may be other letters, but these are found in 95% of cases.

    When you do this, click on the Get FSB button and the sliders will be unlocked. And you will need to move the first slider to the right quite a bit, each time pressing the SET FSB button, so that example = thread the changed parameters. And you will have to do so until then, until you reach the desired characteristics of the processor frequency. If you overdo it, the computer will freeze and you will have to start all over again.

    Overclocking the CPU with CPUFSB

    Utility CPUFSB not much different in functionality from the SetFSB just reviewed. However, there is something to praise her for. The first and rather significant plus is that the utility is completely Russified, which is very convenient, you must agree. The program is more tailored for Intel processors, but it can also be applied to AMD processors.

    To overclock the processor in the CPUFSB program, you will need to sequentially:

    1. Specify the necessary information about your motherboard and the type of clock (Clock Generator).
    2. Then click on " Take frequency ".
    3. Move the slider to the right to change the frequency of the sample.
    4. At the end, click on “ Set frequency ".

    There is nothing complicated. You can intuitively figure out the settings even without prompts.

    Other programs for overclocking the processor

    We have considered in more or less detail the most frequently used programs that are used to overclock the processor. However, the list of programs does not end there. But we will not describe them in detail, because the principle of their operation is similar to the previous ones. Here is a small list of overclocking programs that you can use if the first ones did not suit you or you could not download them.

    1. Over drive
    2. Clockgen
    3. ThrottleStop
    4. SoftFSB
    5. CPUCool

    Output

    Now you know how to overclock the processor, or maybe you even tried to do it yourself while reading the article. I hope everything went well for you and without any unpleasant consequences. Remember the golden rule - Better tit in hand than pie in the sky ! Therefore, do not overclock, otherwise you will have to buy a new processor, and maybe even a motherboard.

    Avid gamers, people who work with bulky multimedia, and those who need complex computing processes often face a lack of power in their equipment. And if they do not want to spend money on upgrading equipment, or there is no need for a dramatic increase in performance, then overclocking or overclocking the processor, video card or RAM will help.

    How to overclock a processor

    Overclocking or overclocking is an increase in the performance of components of a personal computer by software or physical manipulations.

    Sources of additional power

    All devices operate normally at 50-80% of maximum power. Restrictions are imposed by manufacturers and are designed to extend the life of the device. There are several ways to remove or work around these restrictions. True, this will significantly increase the load, and, consequently, reduce the service life of the device.

    Thus, by taking the right actions, you can increase the performance of your processor, video card or RAM by 20-50%. It is quite difficult to achieve the maximum possible productivity - this is already the area of ​​professional activity. But a 20-30% increase can be obtained without delving into the constructive jungle.

    IMPORTANT: Overclocking a processor on a laptop is an extremely risky step and it is strongly not recommended to take it.A weak cooling system does not prevent the consequences of a rise in temperature. Therefore, you need to think carefully before overclocking a laptop processor.

    The following will provide tips on how to properly overclock the processor. On motherboards with built-in overclocking utilities, it is difficult to damage your computer. Special software fuses, when an excess of normal temperature is detected, reset the settings to their original state.

    Despite all the precautions, it is better to play it safe and provide additional cooling before overclocking the processor.

    Overclocking the processor correctly

    Correct CPU overclocking

    There are two ways to effectively increase the processor clock speed: adjusting the BIOS settings and special software. Both methods are relatively safe and accessible to users with modest computer knowledge.

    IMPORTANT: Before increasing processor performance, it is better to think carefully. If there are doubts about the successful completion of the overclocking procedure, then it is better not to proceed with it. Incorrect actions are fraught with damage to devices.

    Correcting BIOS settings

    Before overclocking the processor through the BIOS, you must carefully study the instructions for the motherboard. All the required values ​​can be found in it. In addition, it indicates the presence of special switches on the board that are responsible for increasing performance. Using them can also improve system performance.

    The increase in the clock frequency using the BIOS is due to the change in the FSB multiplier. This feature is only supported by open multiplier processors. Otherwise, you will have to resort to software overclocking or soldering contacts. The technical documentation for the motherboard should contain information about the FSB bus multiplier.

    To overclock the processor through the BIOS, you must perform the following steps:

    1. Go to BIOS (Del or F12 key, depending on the motherboard and the installed BIOS version);
    2. Select the appropriate menu section (MB Intelligent Tweaker, M.I.B, ​​Quantum BIOS, Ai Tweaker). There are a lot of options, all of them cannot be described in one article. You can determine the required parameter by specifying the motherboard model on specialized forums and sites;
    3. Find an item containing information about the clock frequency of the FSB bus (this will be a three-digit number with the prefix mHz, in some BIOS versions this item is designated as "CPU Bus");
    4. Find the item CPU Ratio (bus performance multiplier); Overclocking the processor via BIOS
    5. Set the multiplier to the required value (you can calculate the required value as follows. Nominal clock frequency + 20-30%, divide the result by the FSB multiplier and get the required coefficient);
    6. Exit BIOS and save changes.

    If after loading the operating system a blue screen appears or disks, sound cards or other elements are not recognized, then the overclocking threshold has been exceeded. You need to reduce the ratio and try again.

    After completing these steps, you need to check the processor temperature (special programs like Everest or HWmonitor will help). The maximum allowable value at peak loads - 900C ... If the indicator exceeds the permissible value, then it is necessary to reduce the coefficient or provide sufficient cooling.

    It is better to gradually increase productivity, increasing the final value in a certain increment. After reaching the required frequency, you can stop, or you can continue to increase it. When the maximum value is reached, the computer will stop turning on.

    How to properly overclock your processor on a PC

    To restore normal operation, you must reset the BIOS settings. This can be done by pulling out the battery on the motherboard for ten seconds. If the computer still does not turn on, remove the battery and close the jumper labeled CCMOS. It is usually located next to the battery slot.

    Having found the optimal value, you need to work at the computer for half an hour. If during this time the temperature has not increased, the system has not malfunctioned, then everything is in order - the overclocking was successful. Now there is no need to worry about how to speed up the processor.

    Software overclocking

    The debate about how best to overclock the hardware continues. Security advocates sin on the unreliability of software, while those who prefer to overclock the processor through a program fend off its simple use. With the right actions, any method will be effective.

    There are several manufacturers of motherboards. Overclocking software is also targeted at various manufacturers. Overclocking an intel processor with the wrong utility can cause serious damage to the system. The places where such programs are downloaded usually contain information about the list of supported models of processors and motherboards. Therefore, before overclocking an intel processor, it is best to check the above list.

    Программы для разгона процессора

    ASRock OC Tuner

    Simple and functional program for overclocking the processor. OC Tuner combines overclocking and monitoring functions. With its help, you can not only overclock the processor, but also get information about the state of the system, monitor the voltage in various elements of the system.

    To change the processor frequency and bus frequency multiplier in the Over Clocking section, just set the required parameters in the appropriate fields and click the Go! Button. Along with the processor performance, you can also adjust the PCIE bus frequency. Voltage control works on the same principle, only there are more input fields (CPU, RAM, VTT, chipset bridges). Suitable program for overclocking an Intel processor.

    MSI Control Center II

    The program is designed to control the state of the system and its overclocking. The entire interface of the utility is divided into two main sections: "Oveclocking" and "Green Power". The overclocking functions are grouped in the first section. It also contains information about the status of devices: temperature, power consumption, and more.

    The second section "Green Power" contains information on the overall energy efficiency of the system. Also from this menu, you can turn on and off the LED indicators of the motherboard.

    ASUS TurboV EVO

    Program for overclocking motherboards manufactured by ASUS. Owners of motherboards from this manufacturer can instantly overclock their devices without learning the BIOS and other subtleties. All you need to do is install TurboV EVO. Moreover, in some versions of the EFI BIOS, the utility is embedded.

    With TurboV EVO, you can monitor the processor clock speed and adjust the memory frequency. The program also supports the function of voltage control in various elements of the system. The possibility of automatic system overclocking is provided.

    AMD OverDrive

    How to overclock an AMD processor? There is an excellent AMD OverDrive utility for this. The program has several levels of settings. They adjust to the user's level of awareness. Inexperienced users will have access to monitoring the system operation. Those with a sufficient level of knowledge will be able to adjust the bus frequencies and the clock frequency multiplier.

    In addition to fine-tuning the frequency of each core, OverDrive allows you to test the system with the selected settings. The monitoring features make overclocking the AMD processor a lot easier. OverDrive turned out to be a powerful utility for fine-tuning systems to fit your needs.

    Another useful program for overclocking a processor is CPU-Z. It is a good tool for monitoring system health. AMD processor overclocking software provides information on how it works. Its model, total clock speed and frequency of each core, bus multiplier and much more information.

    CPU-Z is a portable program that does not require installation. System information is available immediately after launch. In addition, the utility has a function for publishing and comparing the results obtained, which allows you to monitor the progress of other users who have decided to overclock the processor.

    Adequate PC performance for many novice users is ephemeral. Because each user has their own ideas about how fast their computer should be. However, at some point (for example, when installing a resource-intensive program), the user observes a strange and, say the truth, inconvenient in terms of the properties of its manifestation, the behavior of a computer - the computer starts to slow down mercilessly. At such moments, the implemented process can help the user - overclocking the processor through the BIOS. Read here and now how this is done correctly in practice, what should be taken into account at the time of such an overclocking operation and how to avoid irreparable errors when overclocking the CPU!

    An introduction to thermal safety

    Any increase in the clock frequency of the central processor inevitably leads to one thing - an increase in temperature indicators. In simple words, an overclocked processor will heat up more than a normal CPU (stable default settings).

    original

    Exclusively in view of the latter factor, it is necessary to increase the tactical and technical characteristics of the CPU with extreme caution. Moreover, the correctness and reliability of the overclocking process can only be guaranteed by your own accuracy and consistency in actions. Last but not least, before starting the practical overclocking of the CPU, you should carefully study a number of technical issues, namely:

    • Check out the characteristics of the installed processor (manual and other kind of reference information can be easily downloaded from official sources - the manufacturer's website).
    • Investigate the overclocking potential of a specific CPU modification (unfortunately, manufacturers do not like to share secret overclocking data, so valuable information on CPU overclocking can be found exclusively on specialized sites and forums).
    • Study the motherboard specifications carefully - update BIOS to the latest version .

    After you have complete information about the processor, have an idea of ​​what the reserve potential of an individual PC component means, and your mind and heart are filled with confidence in the well-being of the upcoming event, - start acting!

    How to overclock my processor: step by step algorithm of actions

    bez-imeni-111

    First of all, you need to download several specialized programs:

    • Download the CPU-Z utility (after installing the application, carefully read the table of CPU operating parameters - more details about the process of interacting with the program will be written a little later).
    • Download this software to your computer - AIDA64 (you can download this software here ).

    This is the benchmark software minimum. The use of this software arsenal will allow you, dear readers, to visually monitor changes in the system and, in simple words, not to make trouble.

    Monitoring of operating parameters after the operations of a software upgrade of the CPU (also relevant for other system components) is a mandatory and undeniably useful process, in view of the criticality of overclocking operations of computer components.

    Step # 1: Entering the basic BIOS settings menu

    Depending on the version of the microsystem used, the section in which you, dear friends, have to make changes, may have a name different from that indicated in the example described below. However, it is not difficult to grasp the meaning of the correctness of the selected item in view of the specifics of the applied standardization in the names of the BSVV options.

    161201151244

    In our case, the new BIOS / UEFI interface version 2603 from the company is used as an example. American Megatrends Inc ... (the most common variant in modern computers).

    We will focus on the traditional option - when turning on the PC, press the "F2" or "Delete" service key several times.

    Step # 2: Which overclocking scenario to apply?

    So, after you have entered the BIOS, activate the "F7" key, after which you will find yourself in the menu for additional settings of the basic microsystem.

    • Go to the "Ai Tweaker" tab to the section you need.

    161201145654

    Here you should choose a specific scenario for overclocking, the implementation of which should be justified by your own "discretion" regarding the question of how hard you will drive the processor. The most painless way to tweak the cogs of speed optimization is the “Ai Overclock Tuner” option with the “Auto” option active.

    • We set the value to automatic mode, save the changes in the BIOS setting (F10) and reboot the system.

    This option has a number of advantages, the BIOS system will automatically set the values ​​of increased performance, reserving the right to allocate system resources according to the conditions laid down by the manufacturer. In other words, by activating the mentioned mode, you will maximally protect yourself and the system from unforeseen errors that may be made during the manual overclocking process, which is described in more detail below.

    Manual method of overclocking the CPU through BIOS

    161201145642

    What are the advantages of this method of upgrading the CPU:

    • Increasing multiplier values implemented by an arbitrary method.
    • You can increase the operating frequency of the CPU core at your own discretion.
    • The use of a manual method for correcting the voltage parameters of the specified PC component to achieve stability in the CPU operation is also permissible in the "Manual Overclocking" mode.

    The last example is the most dangerous and is associated with a possible damage to the functional part of the CPU. As you understand, dear readers, if you want to achieve the maximum effect in terms of a software upgrade of the CPU, there is nothing to do here without confidence and firm conviction in the correctness of the settings applied.

    161201145812

    Otherwise, you just simply “fry the flint”. In other words, you will burn the processor. However, as a rule, BIOS will not give a run to obviously harmful installations, your system simply will not start.

    To eliminate the "last trouble", it will be necessary to return the BIOS settings to their original state.

    Step # 3: Checking the hardware after the applied overclocking scenario

    So, after you've tapped into the overclocking potential of your processor, a comprehensive analysis of the performance of the CPU is required. In other words, it is necessary to examine the "patient" for his healthy state:

    • Open the previously installed CPU-Z utility and carefully read the list of the parameters involved.

    snimok-ekrana-111

    • Go to the "Test" tab into the check window and launch the service utility by pressing the "Stress CPU" button.

    snimok-ekrana-113

    The process of the subsequent test, to determine the proper level of stability, is carried out through another program - AIDA64.

    • Run the previously downloaded software.

    snimok-ekrana-105

    • Go to the sensors section, make sure that the temperature values ​​are normal.

    Attention: it should be borne in mind that such characteristics as the thermal capacity of the processor and the effective ability of the cooling cooler to remove the heat generated by the CPU are inseparable concepts. Because without proper cooling, the whole overclocking venture is simply doomed to failure. Make sure the cooling system matches the applied CPU overclocking scheme.

    snimok-ekrana-107

    • Next, you should conduct a series of tests for the stability of the overclocked component - go to the "Service" section, and activate the item "System stability test" from the drop-down menu of the program.

    If the test for "survivability" passed in a positive way, then you can be congratulated. However, it should be understood that the life of a component that operates at maximum permissible speeds is reduced. Therefore, before you rejoice at the fantastic efficiency of an overclocked CPU, think about how expedient it is to "fly quickly into the abyss of digital death."

    Software overclocking of the processor

    There is an alternative overclocking method: you can optimize the CPU using special utilities.

    For AMD CPU, this is the AMD OverDrive program (you can download it from the official website - http://www.amd.com/ru-ru/innovations/software-technologies/technologies-gaming/over-drive ).

    Intel processors are chased by this program - SetFSB (to download the software, click on this link - http://www13.plala.or.jp/setfsb ).

    In both the first and second cases, the desired effect is achieved only if the processor's multiplier complies with the "Unlocked" standard. Unfortunately, there is no other way.

    As an example, let's see how AMD's processor overclocks ...

    We have just such a CPU with the promising Black Edition addition.

    1111111119

  • So, let's run the overclocking program.
    • Go to the "Clock / Voltage" tab.
    • Activate the "Turbo Core Control" button and uncheck the "Enable Turbo Core" item.

    snimok-ekrana-97

    • The next step is to increase the value of the multiplier.
    • We will also increase the power parameters - voltage.
    • After you enter the above values, click the "Apply" button, then "OK".

    snimok-ekrana-99

    • The changes will take effect after you affirmatively agree to the request for a service message by pressing the "OK" key.

    In order to make sure that the settings are stable, a test is required (you already know how to do this!).

    In conclusion

    In this article, we have only scratched the surface of the "overclocking issue". Overclocking computer components is a rather specific topic that requires a lot of knowledge in the case of practical overclocking operations. However, you got the basic concepts.

    So, how the processor is overclocked through BIOS is no longer a secret for you. Well, if you need it - it's up to you! Nevertheless, be aware that the most effective increase in CPU performance is achievable only when the user understands all the subtleties of the "behavior" of the main computing component of the computer - the central processor. Be selective and don't overclock experiments. Remember, you drive quieter - you will continue!

    A source

    Overclocking (overclocking) processors is one of the most affordable ways to increase the performance of a workstation without impressive financial costs. However, beginners often do not understand how to approach this business and are worried about the system's performance in case of improper overclocking. In fact, basic overclocking is fairly easy to do with the right hardware.

    Where to start

    It should be noted right away that almost all processors from AMD (Ryzen or FX) are overclocked, while Intel will have models with the “K” or “X” index (for example, Intel Core i9-9900K or Core i7-9700K). You will also need a motherboard with a suitable chipset for overclocking.

    Without going into details about the chipset, we can say that for overclocking Intel will need motherboards with a chipset marked "Z" or "X" (Z99, Z390, X99, X299, etc.). For "overclocking" processors from AMD of the Ryzen family, any AM4 motherboard socket on B350, B450, X370, X470 or X570 chipsets is suitable. The exception is the A320 chipset, which does not support overclocking AMD processors.

    The principle of overclocking any processor

    Each processor consists of multiple cores that run at a specific clock speed, measured in GHz (MHz). This value shows the number of processor cycles per second and is obtained by multiplying the processor multiplier by the bus frequency (a certain trunk channel that provides interaction between the processor and the chipset). The bus frequency is now a constant value. Thus, we get the base frequency of the processor (or the frequency of all cores), for example, the Intel Core i3-9100F processor, according to the characteristics, has a base frequency of 3.6 GHz, that is, its base multiplier is 36:

    36 (multiplier) x 100 MHz (const bus frequency) = 3600 MHz.

    In addition to the base frequency, almost any modern processor has a Turbo Boost mode, when the multiplier automatically changes, overclocking the processor cores. For the same i3-9100f, this value is 4.2 GHz, that is, according to the formula, the processor multiplier in the load changes to 42 instead of 36.

    The principle of overclocking processors is to increase the processor multiplier by a value greater than the manufacturer's specified, thereby increasing the clock frequency of the processor cores or increasing system performance by increasing the number of operations processed by the processor per second.

    However, everything turns out to be not so simple. For each processor, there is a certain frequency threshold that it cannot overcome without the threat of core degradation. This threshold is influenced by voltage and associated temperature.

    Features of power consumption of processors

    In order for the processor to operate at higher frequencies, it will require increased power consumption, that is, an increase in voltage. This will cause the processor temperature to increase exponentially. As a rule, processors from AMD or Intel start to overheat and, as a result, turn off or skip clock cycles in order to cool down a little, at around 85-95 degrees Celsius. This is the main limiting factor for overclocking processors.

    Typically, the voltage of processors is in the region of 1.2 V – 1.3 V. At these values, the cooling system is able to dissipate the heat generated by the processor, allowing the system to work stably. To overclock, you will need to increase the voltage above these values, but it is highly undesirable to set it above 1.45 V, especially with a weak cooling system.

    Thus, the whole overclocking process consists in finding the "golden mean" between the maximum processor frequency and the minimum voltage (and, accordingly, temperature) required for stable system operation at a given processor frequency.

    Cooling requirements

    The processor, like any other element of the computer, heats up during operation, so it is necessary to provide the CPU with high-quality cooling. Depending on the architecture, frequency and core voltage, each processor has its own TDP (Thermal Design Power), which is measured in watts and shows the power for which the cooling system should be designed. For example, the Ryzen 7 3700X has an out-of-the-box TDP of 65 watts. This means that a 95W cooler is too much for the overclocked 3700X.

    During overclocking, the heat dissipation of the processor increases, so you should always take a cooling system with a margin. For overclocking powerful multi-core processors, tower air and two-section (or more) liquid cooling systems are well suited.

    Choosing a motherboard

    As already mentioned, overclocking the processor increases its power consumption and the load on the motherboard power circuits. Therefore, for safe overclocking, it is recommended to select a board with high-quality power elements.

    If you wish, you can, of course, overclock even on an entry-level motherboard with a 4-pin processor power connector and 3 power phases. The main thing is that the frequency settings can be changed in the BIOS. However, such experiments can end in tears, because in this mode the iron works "for wear and tear", and it is not known how long it will live under increased load.

    Processor power

    4-pin is suitable for powering processors up to 120W. The computer will continue to work even with a higher power consumption, but the excessive load will negatively affect the state of both the power supply unit and the motherboard (4-pin can simply melt and burn out). Four 12 V wires are double the cross-section of two, which increases the load carrying capacity of the cables.

    It should be noted that even a board with 8 + 4 connectors can be powered via a 4-pin connector, and everything will work. The increased number of contacts is only intended to reduce the load on each element and, consequently, the heating. Therefore, overclocking requires an 8-pin CPU connector, because it is enough for any processor from the mainstream market. Fortunately, in 2020, most power supplies have an eight-pin connector.

    Power phases

    The power supply of the processor on the motherboard must be suitable for overclocking. Since 12 volts passes through the 8-pin connector, and the normal voltage to the processor is 1.2 V – 1.3 V, an element is needed that corrects the processor power supply. This role is taken over by the VRM (Voltage Regulator Module). It supplies power to the processor with the required parameters.

    The multi-phase VRM reduces ripple and electronics stress, which has a positive effect on power system performance. Information on the number of phases can be found on the motherboard manufacturer's website, or by counting the number of chokes. The more phases there are, the less the load on each of the transistors in the network, therefore, the less the total heat dissipation. High temperature affects the resistance of the elements, which negatively affects the operation of the system and may ultimately lead to the failure of the board.

    Cooling of power elements

    In order for the power phases of the motherboard to work stably during overclocking, they need cooling. Therefore, when choosing a motherboard, you need to pay attention to the radiators located on the mosfets. They must be massive enough to dissipate the generated heat and prevent overheating of the power circuits.

    Overclocking process for Intel and AMD processors

    When the requirements have been sorted out, you can start overclocking. It should be said that the principle of overclocking AMD and Intel processors is the same. The only difference, perhaps, will be in the ability to overclock the BCLK bus in AMD Ryzen, i.e. increasing the same constant within 5–8%, but this is a creative process and is completely unnecessary if there is no desire to precisely adjust the RAM frequency, voltage and frequency of the bus itself.

    First of all, you need to go to the BIOS of the motherboard. To do this, you need to start the PC and press the "Delete" key on the keyboard. After that, an interface with a large number of windows will open, but first you need to switch to Advanced Mode. Next, look for the "Advanced" / "CPU Features" tab and disable (Disabled) energy saving technologies, such as:

    • Intel Speed ​​Shift Technology
    • CPU Enhanced Halt (C1E)
    • C3 State Support
    • C6 / C7 State Support
    • C8 State Support
    • C10 State Support

    Next, we are looking for the CPU Load-Line Calibration (LLC) setting in the same tabs. This setting has several levels and is intended for voltage control in loads. It is necessary to choose a level at which the LLC graph will be flat, that is, the voltage at idle and in the load will be approximately at the same level. For different motherboards, LLC levels and their number are different. If there is no graph next to this setting, it is worth looking for such a graph on the Internet for a specific board or experimenting manually by running stress tests to check for voltage fluctuations.

    After the primary settings have been made, you can start overclocking.

    In the BIOS, you need to find the "Overclocking" tab (or different variations of this setting, depending on the motherboard). After that, we transfer the multiplier adjustment mode to advanced (Advanced / Expert / Manual). The field "CPU Ratio" becomes available, initially we set the multiplier equal to the frequency of the processor's turbo boost (for example, for Intel Core i7-8700K this value is 4.7 GHz or the multiplier 47), and we also set the voltage "CPU Core Voltage" to 1.2 V It should be noted that on some motherboards it is necessary to synchronize the change of the multiplier for all cores: the field "CPU Core Ratio" / "Ratio Apply Mode".

    After that, press the F10 key, the settings are saved and the computer restarts. If the system has booted successfully, run a processor stress test (for example, AIDA64) and wait 20-30 minutes. With stable operation and optimal temperatures (preferably up to 90 degrees), you can continue overclocking, increasing the processor multiplier by one until the system stops stably passing the stress test or does not start at all. Then we increase the voltage by 0.01 V. By the way, if the system does not start, and, when turned on, the black screen is on, you need to turn off the PC and remove the CMOS battery from the motherboard (or close the jumper), then the BIOS settings will return to the factory settings, and the overclocking process have to repeat.

    The question of how to overclock a processor is most often asked by people who are unable to upgrade their computer. Done right, PC performance can increase by 10-20 percent. At the same time, overclocking your processor is not always advisable: often it is enough to just increase the amount of RAM. It should be remembered that overclocking can lead to failure of the hardware installed in the computer.

    Security measures

    Increasing the cpu frequency can damage the chips of the chip. That is why novice users need to exercise the utmost care and carefully study the technical characteristics of the equipment used. If you have no experience in overclocking, you should heed a few recommendations:

    • Novice users do not need to increase the voltage of the chip and limit themselves to increasing its frequency.
    • Raising the processor frequency should be phased in steps of 100 or maximum 150 MHz.
    • After making each change to the operation of the system, it must be tested. Pay particular attention to the CPU temperature.
    • Increasing the processor supply voltage should be carried out with the minimum step that is possible on the motherboard, most often 0.05 V. It should also be remembered that an increase in this indicator by more than 0.3 V can pose a serious danger.
    • As soon as the stability test of the system has failed, it is necessary to stop all further overclocking attempts.

    You should immediately warn that the answer to the question of whether it is possible to overclock the processor in a laptop will be negative. Nearly all models under $ 1,000 do not have a good cooling system. In such devices, chips are most often used, the technical characteristics of which differ significantly from the CPU for desktop PCs.

    Overclocking recommendations

    The characteristics of the CPU declared by the manufacturers differ from the maximum by an average of 50-80 percent. This is done deliberately so that in the event of a chip failure during normal operation, the user cannot make claims. If we are talking about overclocking a CPU from Intel, then it should be done only on processors with the "K" index, since the multiplier is unlocked in them.

    Also, a lot depends on the motherboard here, because in some chipsets the overclocking option is simply absent.

    Intel is releasing chipsets for multiple sockets, the most popular of which is now LGA1151. On "motherboards" with this type of connector, overclocking is possible if they are based on a set of microcircuits of the "Z" series (Z 170, Z 270, Z 370).

    Preparatory stage

    Asking the question of how to overclock a processor on a pc, you must first carry out certain preparatory measures. It is not recommended to do this if a boxed cooler is installed on the processor. It must be replaced in advance with a better one. Then you should download a set of utilities designed for stress testing and benchmarking. You cannot do without software that allows you to control the heat dissipation of the CPU. Among the most famous programs of this class are the following:

    • CPU - Z is an extremely popular utility that allows you to find out not only the processor frequency and voltage on it, but also other useful information.
    • Prime 95 is a stress test program.
    • LinX is another benchmarking utility capable of 100% chip load.
    • CoreTemp is a real-time CPU temperature monitoring program.

    Before starting overclocking, it is recommended to conduct a trial benchmarking in order to obtain the initial data for further comparison of the results. You also need to make sure that the multiplier is unlocked, otherwise overclocking will not be possible.

    All actions for the correct overclocking of the processor will be carried out in the BIOS and you need to go into it for review.

    This can be done by pressing the "Del" key when the POST screen appears. However, some motherboards use other buttons such as "F2", "Esc", "F10", etc.

    In older PCs, two versions of BIOS were used, and there are some differences in working with them:

    • AMI (American Megatrend Inc.) - you need to go to the "Advanced" menu and select the item "JumperFree Configuration" or "AT Overclock".
    • Phoenix AWARD - the "Frequency / Voltage Control" tab is used, which can be called to another, for example, "Overclock".

    Modern PCs use the UEFI BIOS, which has a full-fledged graphical interface. The overclocking menus may be called "AI Tweaker" or "Extreme Tweaker" depending on the motherboard manufacturer.

    Via BIOS

    And now about how to properly overclock the processor in the simplest way - by increasing the frequency in the BIOS. First, you need to reduce the speed of the memory bus to avoid possible errors in the operation of the RAM. In older versions, this menu may be called "Memory Multiplier" or "Frequency DDR". Finding the option you need in the new BIOS will be easy. Then you should select the minimum value, and after that you can increase the CPU frequency by no more than 10% (100-150 MHz).

    It will most likely be marked as FSB (Front Side Bus) - bus speed. Its indicator is multiplied by the set multiplier, and the result of this arithmetic operation determines the full frequency of the chip core. After that, the computer must be restarted and a stress test must be performed using the previously downloaded utilities, running them for several work cycles.

    At the same time, the CPU temperature monitor program must be activated. If there are no problems, you can continue to increase the processor frequency. It should be remembered that when the temperature of the chip rises to 85 degrees, overclocking should be stopped. If the system stops working stably after the next change, you should roll back the settings by one step and repeat the stress test.

    Using the multiplier

    This overclocking method can be used on motherboards with an unlocked multiplier. You should first reset the base frequency in order to make a more accurate adjustment of this parameter.

    Beginning overclockers need to remember that with a low frequency and a large multiplier, the system works more stable compared to the opposite situation.

    However, with a higher frequency and a lower multiplier, you can achieve a greater increase in computer performance.

    After lowering the base frequency, you need to go to the BIOS tab called "CPU Ratio" or "CPU Multiplier". There is another possible designation for this option. When the multiplier parameter is brought to a minimum and the system is overloaded, a stress test is performed. You can repeat these manipulations until the first failures begin to appear in the computer.

    Chip voltage boost

    The last in the list is the answer to the question of how to properly overclock the processor using the most dangerous method - changing the chip supply voltage. The option most often needed by an overclocker is called "CPU Voltage" or "VCore". If the first two methods can only lead to the failure of the CPU, then in this situation the motherboard is also at risk. This suggests that the chip supply voltage can be increased only with a minimum step.

    It should be recalled that the maximum limit will be an increase in the base value by 0.3 V. After each change in the operation of the OS, a stress test must be performed. If you have problems with system stability, you can try to decrease the multiplier or the bus frequency. Experienced overclockers use all three methods in combination to achieve excellent results.
