How to overclock the processor on a laptop and desktop computer

Why and in what cases it is necessary to break up the computer's CPU

Why do I need to overclock the processor? The main message of acceleration - is the ability to squeeze the maximum performance out of it. This is one of the nuances of savings on the purchase. That is, the CPU is taken, potentially ready to overclocking, increasing its performance, and the result is a more powerful and productive system for less money.

Especially overclocking AMD and Intel processors

Specific differences in the dispersal of Intel and AMD processors do not. Both can be dispersed in two ways: increasing the reference frequency or the tire increase factor if it is not locked. With regard to individual versions of models of processors, those who have an unlocked multiplier, can pursue to higher values.

How to determine whether the multiplier is unlocked? For such stones both brands have developed a special line: AMD Black Edition, and Intel Extreme Edition. All processors have these consoles have an unlocked multiplier, and they are able to "chase." Also determine the ability to overclock possible by Liter K in the designation of Intel processors and the index of FX from AMD. This method is not universal, as there are models that do not follow these rules, however, have an unlocked multiplier. In the end, we have compiled a list of the processors, for clarity, so that you can understand how to overclock Intel Core i5 processor, the i3 or model from AMD.

How to overclock the processor via BIOS

At the beginning of a bit of theory. To understand how overclocking the system, it is necessary to turn to the history of production of processors. The fact that the manufacture of silicon chips in the end is not always possible to achieve the same frequency. Therefore, manufacturers are testing the resulting products, and already the basis of the results of their mark. In other words, one party processors can get a model with different frequencies. At first, the company did so: those processors, the frequency of which appears to be very low, fell into line inefficient, and those who had higher were considered as the top-end. Computer enthusiasts have quickly realized that even the cheapest processor you can try to disperse or closing the legs or by increasing the frequency of the bus.

First-time producers do not pay attention to such overclocking. Soon, however, it began to use the speculators. They bought cheap processors with good overclocking potential, upgrades and sold them already as a line of more expensive models. Naturally, the producers did not like it. And since then they have become a multiplier block. That is, the acceleration was possible only by increasing the bus frequency. However, for enthusiasts and overclockers later special series of processors have been released, has good overclocking potential. True, they cost much more expensive. Modern acceleration - the busy roads and little interest. Basically these are addicted overclockers and booms.

Well, consider the option of overclocking the CPU through the Bios.

computer stress test

Stress test - a test of the stability of the system. The high load test mode are supplied to units of the system are measured frequency readings, voltage and temperature. Stress test is very useful in overclocking. Since it can be found weaknesses in the system and how it remains stable after rising characteristics. For the implementation of stress tests using different tools. One of the most interesting of them - AIDA64. Although its main function - to display information about the system, which may be useful, for example, to determine the current temperatures before overclock the Intel Core i3 processor, in my toolbox and it is a good test stability. You can even use the program to recommend Overclock Checking Tool. She sharpened it was mostly under stress testing. During acceleration, it is desirable to drive similar software system after each change of parameters, it will allow both safer to overclock the processor as possible. If the stability of the falls, it is necessary to go back to smaller values.

Correction factor or bus settings

BIOS many modern motherboards in its composition has a handy tool for the manipulation of the crackdown. In older versions, you can do it manually by changing the multiplier, the frequency and voltage. Before you overclock the processor on the computer and to change the frequency of the bus, you need to go into the BIOS and find an item that is responsible for the physical configuration of the tire. It may be called differently in different BIOS versions. In any case, the bus frequency is usually called Frequency CPU or CPU Clock.

This is the base value on which via multiplier formed processor operating frequency. In order to have an opportunity to change the value, most likely, will have to rearrange the frequency control from automatic to manual mode. Usually it is responsible for this CPU Host Clock Control option. It is necessary to translate it in Manual mode. Increase the frequency of the system bus is recommended in small portions of about 5-10 MHz.

After every change you need to save them in the BIOS, restart the operating system and to carry out a stress test. The can and does run a resource-intensive application or a game as a more accurate test. If the system is stable, it is possible to continue experiments and even to increase the frequency. As soon began to observe any problems, it is necessary to return to the previous stable value. In this case, you need to carefully monitor the temperature. Although most systems are equipped with automatic emergency shutdown mechanism, overheating, sometimes still happens.

If the CPU multiplier is unlocked, along with an increase in the base rate can achieve productivity gains by using it. In the BIOS it is usually referred to as the CPU Clock ratio. We need to increase gradually, one step at a time. He increased the value saved, reloaded, check the system for stability, and if all is well, you can improve on. Manually changing the settings will help to disperse the old models of processors, such as Intel Core 2 Duo, and their modifications. Newer usually fit motherboards with existing acceleration profiles.

A little bit about how to overclock the RAM

Performance of the memory depends on two main factors: the frequency and timings. The frequency will depend on the general bus frequency. That is, unless you have overclocked your system by increasing the base clock, you thereby unwittingly increased and the speed of the RAM. As for timing, the detailed instructions for overclocking and setting worthy of a separate article. But there is a more optimal and operational decisions. Many modern motherboards, especially UEFI-supporting, already contain the profiles to configure high-performance memory. Inside the BIOS, they can look like XMP or EPP with appropriate actions, such as: Load XMP. In Russian BIOS embodiments may be present and such point - "Extreme memory profile", which can be converted into mode "Enabled". This is the most effective way to overclock the RAM as one of the components of the system, and in general the whole computer.

How to overclock the processor special programs

Not so long ago it was possible to overclock the processor to perform only under the BIOS. Now there is plenty of software products that allow you to safely guide the system performance and processor without leaving the operating system. Consider a few options for the most popular and affordable solutions on how you can overclock the CPU without the BIOS.

How to speed up the processor via SetFSB

As you might guess from the name, this program changes the basic frequency of the bus. It is quite easy to use, however, has its own characteristics and limitations. In particular, it concerns not all support systems. In order to understand whether or not your system is suitable for overclocking this utility, you need to know what PLL-chip set. Learn it can be to your specification of the motherboard or the CPU-Z and Everest utilities.

After starting the program the main window opens. In it we are interested in «Control» tab. In the drop-down menu «Clock Generator» you need to specify certain previously PLL-chip. If it is not found in the list, it means that your system is not supported. After selecting the chip you have to press the button «GetFSB». Activated sliders responsible for changing the frequency of the system bus. Move them to the desired position and fix the value of the button «SetFSB». That's because, quite simply need to improve system performance. It is worth mentioning that the program allows you to change the characteristics only until the next reboot.

Overclocking via CPUFSB program

An alternative version of the program for the acceleration of the system and processor. Like the previous tool is used for this technique increase the base frequency of the bus. The program's interface, at first glance, a bit confused, but by studying it, we can see that the program is simple and functional. In "Take rate" dropdown menu, select the motherboard used, the identifier PLL-chip and pressed.

After that activates the ability to change the value of the arrows. you have to press "Set Frequency" after selecting the desired value. The program allows you to use the saved optimization settings, not only for the current session, but after reboot. To do this, there is an item "Set FSB On the next start." In general, as in the previous program, overclock CPUFSB quite simple.

Acceleration processor via OverDrive Utility

This program is for overclocking, AMD processors. Developed by them, so you can download it from the official site. The program is quite complicated for a beginner, but you can understand it. The program interface consists of two panels. Left are categories on the right - the parameters of your search. Overclocking you need to go into the category Clock / Voltage. To activate the slider, responsible for the setting, you need to click on the Turbo Core Control button. After adjusting the desired frequency, it remains only to apply the changes.

It is worth noting that this utility allows you to not only increase the performance of the system, but also to monitor its condition. This can be very helpful before you start overclocking processors from AMD, as it allows you to roughly estimate the full potential of the system. If you do not know how to overclock the CPU cooler, this utility will install the RPM speed values ​​manually, for example, always to the maximum.

Asus TurboV EVO

This program will help to optimize the system on motherboards from Asus. Overclocking the CPU and the memory can be made without departing from Windows. Stylish and intuitive interface is so simple that describe step by step acceleration method does not make sense. The program itself will lead to the desired result.

Is it possible and if you need to overclock the CPU on a laptop

Generally, overclock the CPU on a laptop - employment risk and unpromising. Special performance gain will not achieve because of the fixed power supply system and the limited cooling. This procedure can be carried out more or less on older notebook models, which are not sorry to lose, and you want to squeeze the maximum performance out of them. However, in most cases, overclocking leads to instability.

Simple overclocking Windows tools

This acceleration, in fact, it is not overclocked. This is only a simple optimization of the supply system. First we need to go to "Power and sleep mode" control panel. Depending on the version of Windows, you can get there in different ways. Here interested item "Advanced power settings".

It includes a power management circuit. The default is a balanced option, which improves performance and reduces power consumption when not in use, if necessary. To see all the possible schemes need to click the arrow to "Show additional plans." The list to choose high performance. This mode at the expense of greater power consumption will use the CPU and the entire system for peak performance.

Overclocking via BIOS

Special differences from overclocking via BIOS is not a desktop computer. Technology and technique are the same. Just should bear in mind that the power supply and cooling of the notebook is not designed for higher performance. Therefore, if you increase the frequency of the bus, it should be done very small steps, each time checking the stability of the system and paying attention to the temperature. Generally, when you've decided on this, you can install additional cooling pad with good cooling factor. This is at least to some extent, it helps keep the laptop from overheating.

The list of processors with unlocked multiplier

We have prepared for you a small table, which presents the processors overclocking potential, ie with an unlocked multiplier.

We are sure that after reading this article questions about how to properly, safely, and effectively speed up your processor, you will have less. If you know of any additional tweaks and PC overclocking techniques, we will be happy if you share your knowledge with other readers of our portal.
