How to overclock the processor via BIOS

Improving the performance of a computing system by increasing the clock frequency of some hardware components provided by the manufacturer is called overclocking or to break the processorAs a rule, when it comes to such an operation, it implies the consideration of the question: "How to overclock the processor?". Although the term “overclocking” is much more capacious and includes an increase in the frequency of operation of the memory modules, video cards and even the adjustment of the modes of microcircuit-bridges (recently lost its relevance). Moreover, if we talk about the computational core, then there are both special utilities for overclocking the processor and methods for making hardware changes. In other words, the chip can be “overclocked” with programs, as well as with jumpers on some motherboards.

How to overclock the processor: programs

In this article we will talk about how to do it programmatically - through the BIOS, but it is also worth pointing out one of the most popular applications of this kind.overclocking toolsAmong them are Right Mark Cpu Clock, Set FSB, CPU FSB and specialized programs, often supplied on disks with drivers for motherboards of various manufacturers. There is nothing complicated in using this group of applications: a slider for selecting the reference (or resultant) frequency, a multiplier, the core supply voltage — even a person without computer experience will quickly understand them.

How to overclock the processor through the BIOS

One of the most effective ways to increase the performance of a central microcircuit by increasing the frequency of its operation is to make changes to the BIOS of the motherboard. A BIOS is a collection of small programs stored on one of the mainboard chips. Each time the computer is turned on (even before the operating system is loaded), these programs are activated and perform a number of simple tasks — configure the operating modes of the components, perform basic testing, and organize low-level interaction. The user can make valid changes to the configuration algorithm, thereby achieving the desired results. In order to get to the settings menu, you must immediately after powering on the system unit, press and hold the Delete button (in laptops this could be F2, etc.).In the list that appears, you need to find a section with the settings of the processor - FSB, multiplier, voltage. It is impossible to accurately indicate the location, since it depends on the version of BIOS and the manufacturer.

From theory to practice

CPU overclocking on a laptopIt is impossible to consider how to overclock the processor, without at least a general understanding of the process itself. The frequency of the microcircuit is formed by multiplying any fundamental (reference, FSB) frequency by a multiplier factor. So, a 1 GHz processor can actually work as 200 MHz * 5. Thus, for overclocking there are two ways - to increase the FSB and / or ratio. More productive first option. Usually in the BIOS window you can see what the base value of the reference frequency is. For example, 200 MHz. First you need to set 205, save the changes (the dialog appears after pressing Esc) and check the stability of the system. Then repeat the operation, raising a little more. "Ceiling" depends on many factors. When it is reached, it is necessary to reduce the result by 5-10 MHz - for stability. If after the next upgrade the computer does not turn on, then you need to reset the BIOS settings (jumper on the board, specified in the instructions), and then set the detected "ceiling".For further increases, it may be necessary to increase the voltage in minimum steps.

Use multiplier

It is also possible to overclock the processor using a multiplier. The algorithm is the same. This feature is realized only in special models of processors, where it is clearly indicated (AMD Black Edition).
