What is an overclocker. A brief explanation of a steep overclocker who is such an overclocker

ClockGen (temporarily unavailable)

To monitor the overclocked system, most often use:

- Basic information about computer components
Native Specialist - Full IPF information about AMD64 processors
NextSensor - Monitoring of temperatures and voltages

Most modern video adapters support the change in clock frequencies graphic processor (video processor) from operating system. IN recent versions ATI and NVIDIA video adapter drivers are able to accelerate the video card without resorting to the help of third-party utilities. To overclock the popular video adapter models from under Windows, utilities are used:

- Overclocking and testing stability video cards NVIDIA
ATI Tool - acceleration and testing of the stability of ATI video cards, test stability and NVIDIA video cards
ATI Tray Tools - Acceleration and Testing Stability ATI video cards
FURMARK - He "Bublik" - testing stability. Loads the system to the maximum, it is not recommended to use even in standard modes with weak power blocks.

From third-party utilities for overclocking and configuring the video subsystem, you can highlight the popular PowerStrip program that supports multiple video cards of various manufacturers.

RAM acceleration (operational storage device)

The direct acceleration of RAM is reduced either to an increase in the nominal clock frequency of the microcircuit of the memory modules (MeMCLK), or to change the delays of the main control signals - synchropulse or "timing" (from Ang. Timings - time delays), such as TCAS #, TRAS #, TRCD # and others. To achieve higher memory operating frequencies, taking into account stable operation, as a rule, increase the nominal operating voltage on the memory modules (VDDIO). Changing MEMCLK frequency values \u200b\u200band sync pulses is possible in BIOS Setup motherboard either from under Windows OS using appropriate programs, such as Brain Identifier, AMD Overdrive (for AMD64) MEMSET (Intel architecture processors).

To continuously fix the modified values \u200b\u200bof the frequency-temporal parameters of the operating, you must resort to partial reprogramming of the SPD content (Serial Presence Detect) microcircuit of the memory module. For these purposes, either hardware or software method is used. The latter most simple and does not require any additional fixtures and programming devices. Overwriting and editing SPD data SPD microcircuits, as well as upgrading EPP and XMP profiles firmware, SDRAM architecture modules, DDR SDRAM, DDR2 SDRAM and DDR3 SDRAM is carried out using the Thaiphoon Burner utility.

Criterion stability of overclocked components

The main criterion for the stability of the overclocked components of the computer is their ability to withstand any computational load with a statistical probability of issuing an error in calculations that does not exceed that for components operated in normal mode. Since in most cases the computational load on the components of the computer is much smaller than the potential computing power, special tests are used to identify errors in the operation of the overclocked component (instability).

Improving the stability of the overclocked system

To increase the stability of overclocked systems, an increase in supply voltage (and, as a result, an increase in the supplied and dispersed capacity) is used), as well as improved heat outlet (cooling) and a decrease in temperature.

Raising supply voltages from BIOS

The BIOS of most modern motherboards allows you to change the processor voltage (Vcore, VCPU parameters), the northern bridge from the motherboard chipset (VDD parameter), as well as memory modules (VDIMM, VMEM parameters). It should be remembered that raising the voltage, especially with insufficient cooling, can cause the computer component output.

Increase the supply voltage by voltmode

Sometimes the voltage adjustment range provided motherboardIt turns out not enough. In this case, as well as to control the voltages of the graphics processor and the memory of video adapters, it is resorted to the modification of the supply schemes (Volt-modification, Volt-mod from the English. volt.age. mod.ification is a change in voltage). For this, such constructive changes contribute to the power scheme that lead to an increase in voltages on the outputs of these schemes. Often for the volt modification, it is sufficient to change the rating of the resistor in the power scheme.

There are also industrialized devices for modifying the supply voltage components of the computer.

Cooling system used overclockers

Air cooling systems

Air cooling in the overclocked system

The absolute majority of overclockers use the most affordable, air cooling systems. They are based on a classic radiator or cooler.

Radiators Usually used to cool the memory chips and chipsets of motherboards, since they have sufficiently modest heat sink capabilities. There are exceptions (for example, the Ninja radiator produced by Scythe), when the radiator with a developed surface of the heat exchange can be used to cool the overclocked central processor.

CoolersUsed overclockers, most often have a developed heat exchange surface (exceeding 3000 cm 2), and can also be equipped with large (more than 80 mm) fans, thermal tubes, thermoelectric elements (Peltier element) or other devices that increase the power that the cooler is capable of dispel.

Homemade

Famous trademarks of coolers used by overclockers:

Liquid cooling systems

The second place in popularity is occupied by liquid cooling systems, the main coolant in which is liquid. Most commonly used water cooling systems (His) in which the working body is water (distilled, often with various additions of an anti-corrosion character). Typical it consists of a water block (Waterblock, from the English. waterblock.), in which heat is transmitted from the processor to the coolant, pump, pumping water along a closed circuit of the system, radiator, where heat recovery from the coolant air, the tank (serves to fill it with water and other service needs) and connecting hoses.

One of the variants of the liquid cooling of the computers is the dive of the computer entirely or its components into the oil (suggested by Tom "s Hardware Guide).

Others (extreme) cooling systems

To cool the computer components, overclocked to the frequencies close to the technological limit, can be applied extreme cooling systems. These include systems using liquid nitrogen, dry ice, various refrigerants (for example, freon), as well as cascading cooling systems. In most cases, ensure the continuous functioning of extreme cooling systems, their creators are not in a position, therefore their usual application is to obtain maximum results in benchmarks and participation in various overclocker competitions.

Check the stability of overclocked components

To check the stability of overclocked computer components, a number of program tests are used. None of them in itself guarantees 100% of the stability of the system, however, if the test revealed a failure in the system or cannot pass to the end, acceleration should be considered unsuccessful. Most tests create an intensive computing load on various blocks Central processing, system memory, graphics processor and system logic set. Only a combination of several tests can serve as a basis for confidence in the stable operation of the computer. Here are some of the most popular stability tests.

Overclocker - a person who wields the frequency of the central processor several times higher than its possibilities of software. You can "overclock" by increasing the supplied voltage, the frequency of memory or tire and the installation of new drivers.

The need for overclocking appears when the car bought out a few years ago, and there is no possibility to change it to new desires. And then the overclocker artificially improves the work of his PC.

What are the types of "overclocking"

With the factory form, all the necessary components manufacturer produced himself, slightly increasing their parameters. Custom acceleration provides only overclocking actions. Here everything will depend on the possibilities of the user and his desires. It can choose a minimum of parameters that are responsible for overclocking, or dwell on automatic acceleration, acting through software or BIOS motherboard. Such an acceleration involves an increase in the frequency of the system bus without changing other settings.

With a reasonable method, the user significantly increases the clock frequencies, not reaching limit values. In this case, the car can work for a long time in this mode, and not stopping. For the embodiment of desires to life, both BIOS and software methods can be used. And it is possible, without being causing a sly, arm the soldering iron and change the frequency of the clock generator, multipliers of secondary devices that accelerate along with the bus, the supply voltage of the processor, its architecture and special parameters of a particular chipset. In addition, the change can be subjected to the change random access memoryDepending on the system tire, and timings. Often the resulting "stove" requires a reliable cooling system.

With an extreme form of overclocking, the overclocker increases the work parameters to the proceedable values. Here, without a cooling system, it is definitely not to do. To this end, freon cooling, liquid vacuum, liquid helium, liquid nitrogen, cascade systems and others are used. But even this will not save the car from the need to replace pale iron.

The back of the medal

Such technical improvement requires an increase in voltage. Together with increasing temperature, the lifetime of the PC is reduced directly proportional to the overestimation. Therefore, after a few years this work will have to buy a new computer.

This dictionary was compiled on the basis of the current experience of the author specifically for steep overclockers, who wanted to assemble or steeply dispersed their already cool computer.

Mother, Momka, motherboard, motherboard - main device in a computer. It is intended for stuck in it all other devices and stones. Cooling is determined by the price, the manufacturer's friendship, the amount of diarmatal applied and overclocking capabilities.

Hands - the main tool of overclocking. Cooling is determined by the degree of directness or curvature. At the initial stage, the degree of curvature is increased, with an increase in the number of twisted boards, it decreases, which, however, does not exclude the possibility of its repeated jump-like growth.

Stone, processor - the main object of overclocking. Cooling is determined by the frequency, cache size, manufacturer and degree of dispersion. The relationship does not have a relationship.

Greetings! Today's article I want to start a small series of articles on overclocking. Since the article is basic, then we will consider only the basic concepts, but let us touch this topic in more detail in the following articles. And today you will learn what overclocking is and why it is needed.

What is overclocking? (This article)

What is overclocking with ordinary words?

According to the already established tradition, I will tell you what is overclocking so that everyone is understandable. No dwarf phrases.

Overclocking (or overclocking a computer) is a process during which the PC performance increases physical or programmatically.

Speaking about the dispersal of the computer, it means overclocking the three components - the central processor, the video card and RAM. This is all done on their own and absolutely free, so many users of the obsolete PC are first trying to "squeeze all the juices from it" and only when this becomes not enough - buy new equipment (make an iron upgrade). Read more, and this year.

The only thing for which you have to pay when the computer is accelerated is for stronger cooling. Why? Yes, because with increasing performance, the heat generation of overclocked components is very much. If you neglect the improvement of cooling, then such a computer does not work for a long time, because when heated, the wear of the computer components is enhanced. Yes, electronics loves comfortable temperatures. That is why, by the way, manufacturers of any electronics warn that it is impossible to allow direct sunlight onto it.

What is needed for overclocking?

As I said, overclocking increases computer performance. Accordingly, it is needed primarily to those people who are critical of the PC power is critical, but there is no wishes for the purchase of new components (or opportunities).

Gamers may well be such people. For example, a new game came out, which only goes on the minimum graphics settings or slows down. You can overclock the computer and enjoy this game. In addition, it will be possible to save a little on the heating of the room.

There are also people who are simply evaluated from overclocking and accelerate everything they fall into hand, and then measure the results with the other such acceleration fans. There are special forums and sites dedicated to this topic. Even the most topical processors accelerate just to see what you can squeeze. Once I try to overclock your computer, you can completely lose control of yourself and join the society of such enthusiasts. Keep yourself in your hands. In everything you need to know the measure.

How does the overclocking work at all?

How does ovelocking work? Or it will be correct to ask a question like this: due to what resources is accelerated? And everything is very simple. Manufacturers are always laid in a product of a productivity in the product so that this product will work without any problems.

That is, the same processor can work with different frequency, but manufacturers select such a basic frequency for the processor at which it is reduced to a minimum of the likelihood of achieving its critical temperature in which it can burn.

It is for this reason that it is very important to take care of if you thought about the acceleration of the computer.

Extreme overclocking

Output:

If you want to know what overclocking is in practice, I advise you to stay with us. The following articles will consider special programs for overclocking the processor and video cards, as well as other overclocking methods.

Drawing up the computer acceleration at home, follow the golden rule "Cherry you go - you will go further." Otherwise, your delight from productivity growth may be short. Sometimes it is possible to output not only an accelerated video card or processor, but also a motherboard with a power supply.
