With all chip New to the world always found those who tried to push it on, far beyond what they defined in the factory. We gathered here today to summarize 10 years in the field. OverclockingOf course.
In 2001, the processor market was on the rise, and with it the processor processor field also developed. If once you upload a frequency processor of 100 MHz to a frequency of 166 MHz is considered respectable, today speaking in terms of 4.5 GHz and more. And yet, at the time, the field was smaller and more complicated,Willamette (Pentium 4 Intel) had difficulty switching Overclock, And tended to burn if you took them too far.
Despite this,Willamette With a nice legacy: my body Cooling Third Party. The processors were warming up, and end users realized very quickly that the original heat sink was having a hard time dealing with them (and when it did, it's like standing next to a fighter jet taking off). Thus was born the third-party heat sink market, which is flourishing to this day, and allows the performance of a processor from a popular processor to the high-end market.
The birth of Xiani Obercluk
At the end of the scale there are users who buy the most expensive processors, the most sophisticated motherboards, the fastest memories, and use the most extreme cooling devices they can (and we will detail below), all for breaking frequency records or performance. Once the Internet became accessible to everyone, it was also made easy Tell the world All about the crazy frequency to which you brought your new processor, and that's how the Overclocker was born to do it to set records.
In order to bring the processors to a frequency that exceeds more than ten percent of its original frequency, there is usually a need for means Cooling Which can fall below room temperature, meaning gas coolers, liquid nitrogen, liquid helium, or dry ice. Cooling The gas, which is popular for setting records, uses the same principle as a home air conditioner, and basically moves the heat away from the processor, leaving its temperature far below the 0.

Liquid nitrogen cooling is based on the fact that in the aggregate nitrogen gas liquid reaches a temperature of up to 210-° C. The cooling is done using a copper or aluminum pot connected to the processor (through the connections on the motherboard designed for the heat sink). The pot is filled with liquid nitrogen, refueling occasionally, and erupts.

At first the hardware vendors did not like The new sport, Despite the defense mechanisms that had been added to the processor in the meantime and would be extinguished in a moment of overheating. Hardware enthusiasts have discovered that these mechanisms are interfering with them, and just shut them off before rushing. This has undermined the reliability of processor manufacturers, who preferred to try to block the possibility than to continue handling the returns of processors Processors Burned.
productive Processors Against, manufacturers motherboards for
Motherboard makers thought otherwise. For them, if someone was able to break a frequency record on Motherboard Her product was a great honor. This is how we saw motherboard manufacturers switching from using gimpers to change the settings,BIOS Itself and add additional advanced settings.
If ever it was rare to find Motherboard Which allows you to change the parts of memories, today you can control even how much voltage passes through the crystal that determines the frequency of the processor, turn off cores, control the frequencies of the surrounding components, and more.
How much motherboard makers liked the sport, you can see In our review section: There is no single review in which we did not relate to the field of overclocking, And we even set one review To the field,2 Core Duo The legendary. To this day, motherboards from home ASUS Breaking Oracleok records to the left and right, and so deserve their salute.
Memory manufacturers also noticed the phenomenon, and began to release memories to consume work at high frequencies, beyond the original ones. ChipsBH5 They are a good example of this. Despite the power consumption that sometimes reached the 4 volts (the memories are a huge voltage, for comparison, more than 2.4 Volt-DDR2 May kill them without proper cooling), these chips made a force during the rapid attempt, and could also accompany Processors Breakthrough.
Today's cooling towers
The biggest response to Overlock has been seen in the last 10 years by cooling manufacturers. If once a small aluminum block with a fan was enough, the day has We have real cooling towers.
Two new technologies have improved the performance of the heat sink: heat pipes (HeatPipes), And theDHT. The heat pipes, usually made of brass or brass coated with nickel, contain gas in them, which, in response to the heat emitted by a climber along the pipe, reaches up and cools in the heat sink, and so on. The "DHT Allows you to connect the direct heat pipes to the processor, and improves the heat sink performance.
