Perhaps many people know, and who does not know, we will tell that the speed of any computer can be significantly increased not only by replacing the existing hardware with a new one with higher performance, but also by overclocking the old one.
Overclocking or overclocking means increasing the performance of such PC hardware components as a processor, video card, RAM, motherboard by improving their nominal characteristics. In the case when the processor will be overclocked, we will increase its clock frequency, multiplier, and also the supply voltage.
How to increase the frequency
So, how to overclock an intel processor? Talking about methods of this type, let's start with increasing the frequency response. Where does this opportunity come from? The fact is that manufacturers of microprocessor technology always supply their products to the market with a certain margin of safety, the value of which is in the range from 20 to 50% of the characteristics declared in the passport. For example, the Intel 2.5 GHz installed in your PC has a maximum clock speed of 3 GHz.
In other words, in the course of a properly performed overclocking process, it is possible to achieve an increase in its characteristics to a value of 3 GHz. However, this does not mean at all that in this mode it will work longer than at its passport frequency. The peak frequency when the processor is very hot is reset to the minimum values. In addition, there are absolutely no guarantees that you will be able to increase this figure, however, some simple manipulations will allow you to increase it by 20-30% without any problems.
Each processor is characterized by the presence of such a parameter as a multiplier. If we multiply the value of this parameter by the frequency of the FSB bus (BCLK), we will find out the frequency. Therefore, the simplest and absolutely safe method of overclocking Intel is to increase the frequency of the system bus FSB (BCLK).
The availability and simplicity of this method boils down to the fact that the FSB (BCLK) can be changed directly in the BIOS, as well as programmatically, using a step of 1 MHz for this purpose.
In more "ancient" models, the use of such a method could result in sad consequences - the processor could simply burn out. Today, in order to "kill" a modern multi-core Intel only by increasing its clock frequency, incredible efforts will be required. But we do not set ourselves such a goal, and, therefore, this method is quite safe.
In the event that a novice overclocker even overdoes it with the setting, the system will instantly reset the settings, reboot and will function in its normal mode. To change the bus frequency, enter the BIOS, then find the value of the CPU Clock value, press the "Enter" key within this value, and then enter the value of the bus frequency.
Attention! It is recommended to overclock only desktop processors. Processors in laptops are best left in the current state, because. they can not cope with the increased heat dissipation of processors under overclocking. To enter the BIOS, the “Del” key is usually used when booting the PC. Read this article: . But only to get acquainted with the frequency and other parameters.
So, we enter the BIOS, open the information about the CPU and see:
In the settings of the FSB or BCLK line, set new values. In this screenshot, BCLK is equal to 100 MHz, which, when multiplied by a factor of 33, gives a processor frequency of 3300 MHz. If you set the BCLK value to 105, then the final frequency will be 3465 MHz. Be aware that most modern Intel processors are sensitive to changing this value. It is better to overclock them by increasing the multiplier. Read more about multipliers below.
In order for the result of overclocking to be as efficient as possible, it is necessary to replace the existing cooler with a more efficient one. To determine the effectiveness of a particular fan model, you should measure the Intel temperature at its maximum load. This will help programs such as Everest, 3D Mark. If the temperature value at maximum load is 65-70°С, it is necessary to either increase the fan performance to the maximum value, or reduce the FSB bus frequency (BCLK).
How to change the multiplier
Also, performance can be increased by changing the multiplier. This is only possible if the existing "stone" is unlocked with a multiplier. As a rule, such devices are labeled "Extreme". If the version of the existing Intel does not belong to this category, you should not be upset, since the first option will be enough to get it. Or you can not do without increasing the voltage.
We change the multiplier up from the standard one, as in the screenshot.
No need to immediately set large multipliers. Try adding 2-3 units to start with. Save and restart your computer. If it works stably, you can add another unit. And so on until stability is broken. Let's assume that the computer freezes when turned on after setting the multiplier to 45. Then it is better to set the Final multiplier to 43. This way the computer will work stably.
If the motherboard itself cannot reset the settings, help it. You need to remove the round battery on the motherboard. If you don't know what it looks like, you'd better not overclock your CPU!
How to increase the supply voltage
How to overclock an intel processor by increasing the processor voltage? The principle of increasing productivity by increasing voltage is quite simple. To implement it, you just need to increase the power of the device. In order to translate the desired into reality, it is necessary:
- install a more efficient cooler;
- do not increase the voltage value higher than 0.3 V from the nominal value.
In order to increase the voltage, you need to go into the BIOS, find here an item called "Power Bios Setup => Vcore Voltege" or something similar, increase the supply voltage by 0.1 V. Then, you need to set the cooler to the maximum value and set a higher FSB frequency (BCLK) or multiplier.
When individual PC components no longer meet modern system requirements, they are usually changed. However, some users approach this issue more flexibly. Instead of purchasing, for example, an expensive processor, they prefer to use overclocking utilities. Competent actions help to achieve excellent results and postpone the purchase for some time in advance.
There can be two ways to overclock the processor - changing the parameters in the BIOS and using special software. Today we want to talk about universal programs for overclocking processors by increasing the frequency of the system bus (FSB).
This program is great for users with a modern but underpowered computer. At the same time, this is an excellent program for overclocking the intel core i5 processor and other good processors, whose power is not 100% realized by default. SetFSB supports many motherboards, and it is its support that you need to rely on when choosing a program for overclocking. The full list can be found on the official website.
An added benefit to choosing this program is that it can determine its own PLL information. Knowing its ID is simply necessary, because without this overclocking will not take place. Otherwise, in order to identify the PLL, it is necessary to disassemble the PC and look for the corresponding inscription on the chip. If computer owners can do this, then laptop users are in a difficult situation. With SetFSB, you can find out the necessary information programmatically, and then start overclocking.
All settings obtained by overclocking are reset after Windows restarts. Therefore, if something went wrong, the chance to do something irreversible is reduced. If you think that this is a minus of the program, then we immediately hasten to say that all other overclocking utilities work on the same principle. After the found overclocking threshold has been found, you can put the program into autoload and enjoy the resulting performance boost.
The minus of the program is the special "love" of the developers for Russia. We will have to pay $6 to purchase the program.
CPUFSB
The program is similar to the previous one. Its advantages are the presence of a Russian translation, work with new parameters until reboot, as well as the ability to switch between the selected frequencies. That is, where maximum performance is needed, we switch to the highest frequency. And where you need to slow down - we reduce the frequency in one click.
Of course, one cannot fail to mention the main advantage of the program - support for a huge number of motherboards. Their number is even greater than that of SetFSB. This means that owners of even the most obscure components get a chance to overclock.
Well, from the minuses - you have to learn the PLL yourself. Alternatively, use SetFSB for this purpose, and overclock CPUFSB.
SoftFSB
Owners of old and very old computers especially want to overclock their PC, and there are programs for them too. The same old ones, but working. SoftFSB is just such a program that allows you to get the most valuable% in performance. And even if you have a motherboard whose name you see for the first time in your life, there is a good chance that SoftFSB supports it.
The advantages of this program include the absence of the need to know your PLL. However, this may be necessary if the motherboard is not on the list. The software works in the same way, from under Windows, autorun can be configured in the program itself.
Minus SoftFSB - the program is a real antique among overclockers. It is no longer supported by the developer, and it will not be able to overclock your modern PC.
We told you about three great programs that allow you to unlock the full potential of processors and get a performance boost. In conclusion, I would like to say that it is important not only to choose a program for overclocking, but also to know all the subtleties of overclocking as an operation. We recommend that you familiarize yourself with all the rules and possible consequences, and only then download the program for overclocking your PC.
There are two most popular ways to overclock a processor. Using UEFI/BIOS or using software running on the operating system. The second method is simpler and allows using specialized utilities to perform overclocking as needed.
Useful Tools
Before overclocking, you should stock up on tools that allow you to view all the necessary parameters of the motherboard and processor and control them in the process of performing operations. A universal example of such a tool is the program CPU-Z. It works on Windows and Android operating systems. Below in the figure, for example Intel Core i5, you can see what characteristics this program can read. The program is constantly updated, modern processors are added to it, and it will perfectly cope with the latest models. Intel Core i7 and AMD Ryzen.
Despite the fact that overclocking is planned to be carried out using software, it will not be superfluous to first update the BIOS to the latest version. This will add functionality to the motherboard anyway.
And it goes without saying that you need to be sure that the cooling system of your electronic friend will cope with the increased loads and is also ready to overclock.
Having completed these preliminary activities in advance, you can begin to explore the possibilities of specialized software.
SetFSB
The first program with which we will begin to study software for overclocking will be SetFSB. As the name implies, it is intended to overclock the processor on the system bus. You can download it on the official website. This utility differs in small size and is delivered as a zip-archive. After unpacking the archive, let's look at its contents, which are presented below.
In the program folder you can find a text file setfsb.txt. By opening it, you can examine the list of motherboards with which it is able to work. It is worth studying it carefully to find your model and make sure that when you run it on your computer, you get the expected result.
During launch, a small window will first appear in which you will need to enter the code indicated at the top of it. According to the developer, this will serve as additional confirmation that you understand how to overclock the processor with this program and take on all the consequences of your actions.
The next window is already the main one for this program, and in it you will need to select the type of clock generator, which is determined by the motherboard model and is registered in the setfsb.txt file, which was studied above.
By selecting the correct Clock Generator parameter, you will have access to change its parameters and, accordingly, you will be able to adjust the frequency of the FSB bus. The program will store the selected characteristics until the OS is rebooted. If you want to automate this operation, you will need to place a bat file specially created in a text editor into autoload.
Another version of the program for overclocking the Intel processor is. Its functionality is almost similar to the one we have already considered. SetFSB, for the better, it differs only in the presence of the Russian interface. Therefore, it may well be suitable for beginner overclockers as a fact-finding one.
The work is based on the same principle, that is, on interaction with the hardware of the motherboard. Supported boards in this utility are visible directly in the drop-down list, which is quite convenient. It is required to select a manufacturer and then specify the type of PLL generator, which is responsible for increasing the frequency of the system bus.
After the necessary input parameters have been specified, you can start overclocking the processor through the program.
AMD overclocking software
At one time, AMD, which had somewhat lost its position in the processor market, made a good marketing move. It released a series of unlocked FX processors and developed its own overclocking software. The program for overclocking the AMD processor is called AMD OverDrive and we will now get to know it in more detail.
AMD Overdrive
So, the first thing you will see after running this program for overclocking AMD processors will be the traditional warning from manufacturers. In a nutshell, its content boils down to the fact that the operations performed to change the parameters of the processor can lead to failures in the operation of your computer, and by performing them, you are aware of your actions and accept responsibility. Of course, you have to agree with this. By pressing the OK button, the main program window will open with the main parameters of the processor installed in the system.
As can be seen below, this information is similar to that obtained using the program CPU-Z and gives general, but exhaustive, information about the characteristics of a given processor.
The tools of this program for overclocking AMD processors that interest us are located in the section on the left " performance control". In it, you must select the item " Clock/Voltage» and proceed to the analysis of the method of operation of the device.
In the figure above, we see the performance of the processor before overclocking and, accordingly, the parameters available for adjustment. To access the value change, you will need to enable the required function using the Turbo Core Control button, which will have a green selection highlight before the operation.
In the window that opens, check the box next to " Enable Turbo Core».
Thus, access to the processor parameters has been obtained, and you can proceed directly to overclocking. The figure clearly shows that when the slider is moved to the right in the " clock» The multiplier indicator increases by the available 3 points. A little higher, you can see how the frequency indicators of the processor cores shift from 3300 to 3900.
Utility test CPU Speed Professional, shows the effective frequency of the processor with a multiplier of 16.5, set by default.
The figure below shows the result of our manipulations. A CPU with a multiplier parameter of 19.5 overclocks at 600 MHz.
The work of the utility was considered in sufficient detail. AMD OverDrive. I must say that this software from the manufacturer works great with the entire line of processors and speeds up their work, starting with processors AMD Athlon.
Motherboard Utilities
Let's pay attention to one more area of development of software designed for overclocking. These are specialized utilities that are placed by some motherboard manufacturers on the included driver disk.
The three largest players in this market offer the following programs:
You can also look for analogues of such programs on disks from lesser-known motherboard manufacturers, with the only exception that they usually come only with products of the upper price segment.
Direction of software development
Above we have considered the most popular solutions for working with processors from the leading manufacturers in this market - Intel and AMD. It is worth noting that such a solution as a program for overclocking the processor directly from the operating system is dying. This is the result of modern trends in the development of basic systems that control the operation of the hardware. Over the past ten years, there has been a significant expansion of BIOS functions and the transition of all motherboard manufacturers to use UEFI, its extended version.
Actually UEFI itself became an operating system in miniature. It has an attractive graphical interface and mouse support. If earlier, to edit the parameters of the basic input-output system, the user needed certain knowledge and skills in working with keyboard switches, now there is no need for this anymore.
The conclusion from this is the following. Owners of AMD processors should not worry in the near future. The manufacturer himself has developed and maintains a high-quality overclocking utility, and the latest models of devices in the series Ryzen are produced with good potential in this area. If you have an Intel processor, then in the light of recent events in the motherboard industry, you should pay attention to studying UEFI. In the next few years, old motherboards will go to their well-deserved rest and overclocking of the Intel platform will be possible only in this way. Even despite the release of the "K" series of processors with an unlocked multiplier, Intel prefers to work with its brainchild - UEFI, and third-party developers in such conditions simply curtail their activities.
Conclusion
According to the tradition that has developed among overclockers, we recall once again that all the consequences of switching the processor to an accelerated mode of operation lie only with the user, and not a single manufacturer is obliged to accept claims in case of unsuccessfully performed actions, and will not. Don't forget this and always be careful. It is better to achieve a small but stable result than to rush and get nothing.

What is overclocking (overclocking)? This is a change in the normal mode of operation of computer devices in order to increase their speed and improve the overall performance of the system. Apart from extreme overclocking, which aims to get the most out of a component and set a record, overclocking makes it possible to meet the growing needs of applications and games without replacing hardware with more powerful hardware.
Today I will tell you how to overclock the processor (CPU). Let's consider the methods and tools used to determine the performance and stability of an overclocked system, as well as a simple way to return it to the "pre-overclocked" state.
Before you start
Any modern processors, even mobile ones, are capable of overclocking, although the latter, according to their creators, is contraindicated due to the inability to provide adequate cooling. Yes, an overclocked "stone" (now and further we will mean desktop PC processors) consumes more energy and generates more heat, so the first thing to take care of is a good cooling system. It can be both air and liquid type, the main thing is that the value of its heat sink ( TDP) matched or exceeded the thermal power of the "stone". For small and intermittent overclocking, the boxed cooler that was sold with the CPU is enough, but under increased load, it will most likely annoy you with loud noise.
The second important detail is the power supply unit (PSU). If his strength is barely enough for the current power consumption of devices, he will not be able to overclock. To calculate the required PSU power, taking into account overclocking, use: select the components that are installed on your PC from the lists and click " Calculate».
Calculator version " Expert” allows you to take into account the voltage and cycles of the CPU after overclocking, as well as the percentage of load on it (CPU Utilization). Choose the last one to the maximum - 100%.
Successful experiments!

How to overclock a processor updated: April 4, 2016 by: Johnny Mnemonic
The frequency and performance of the processor may be higher than indicated in the standard specifications. Also, over time the system is used, the performance of all major PC components (RAM, CPU, etc.) may gradually decrease. To avoid this, you need to regularly “optimize” your computer.
It must be understood that all manipulations with the central processor (especially overclocking) should be carried out only if you are convinced that he will be able to “survive” them. This may require system testing.
All manipulations to improve the quality of the CPU can be divided into two groups:
- Optimization. The main emphasis is on the competent distribution of the already available resources of the cores and the system in order to achieve maximum performance. It is difficult to do serious damage to the CPU during optimization, but the performance gain is usually not very high.
- Overclocking Manipulations directly with the processor itself through special software or BIOS to increase its clock frequency. The performance increase in this case is very noticeable, but the risk of damaging the processor and other computer components during unsuccessful overclocking also increases.
Find out if the processor is suitable for overclocking
Before overclocking, be sure to view the characteristics of your processor using a special program (for example). The latter is shareware in nature, with its help you can find out detailed information about all the components of the computer, and in the paid version, even carry out some manipulations with them. Instructions for use:
Method 1: Optimizing with CPU Control
To safely optimize the performance of the processor, you will need to download CPU Control. This program has a simple interface for ordinary PC users, supports the Russian language and is distributed free of charge. The essence of this method is to evenly distribute the load on the processor cores, because. on modern multi-core processors, some cores may not participate in the work, which leads to a performance loss.
Instructions for using this program:
Method 2: Overclocking with ClockGen
is a free program suitable for accelerating the performance of processors of any brand and series (with the exception of some Intel processors, where overclocking is not possible by itself). Before overclocking, make sure that all CPU temperatures are normal. How to use ClockGen:
Method 3: Overclocking the CPU in the BIOS
A rather complicated and “dangerous” way, especially for inexperienced PC users. Before overclocking the processor, it is recommended to study its characteristics, first of all, the temperature during normal operation (without serious loads). To do this, use special utilities or programs (AIDA64 described above is quite suitable for these purposes).
If all parameters are normal, then you can start overclocking. Overclocking for each processor may be different, so below is a universal instruction for performing this operation through the BIOS:
Method 4: Optimizing the OS
This is the safest method to increase CPU performance by cleaning startup applications from unnecessary applications and defragmenting disks. Autoload is the automatic inclusion of a particular program / process when the operating system boots. When too many processes and programs accumulate in this partition, then when you turn on the OS and continue working in it, too much load may be placed on the central processor, which will disrupt performance.
Cleanup Startup
Applications can be added to startup either independently, or applications / processes can be added themselves. To avoid the second case, it is recommended to carefully read all the items that are ticked during the installation of a particular software. How to remove existing items from Startup:
Defragmentation
Disk defragmentation not only increases the speed of the programs on this disk, but also slightly optimizes the processor. This happens because the CPU processes less data, because. during defragmentation, the logical structure of volumes is updated and optimized, and file processing is accelerated. Instructions for defragmentation:
Optimizing the CPU is not as difficult as it seems at first glance. However, if the optimization did not give any noticeable results, then in this case the central processor will need to be overclocked on its own. In some cases, overclocking is not necessary through the BIOS. Sometimes the processor manufacturer may provide a special program to increase the frequency of a particular model.
