O verclocking is the art of running a computer above its rated speed. The speed rating of a processor, graphics card, or even memory is not necessarily a number cast in stone, but rather a speed which is guaranteed by the manufacturer to run flawlessly within a given power and temperature target. That speed can normally be increased to higher levels, but the faster you run a component the hotter it gets and often requires the use of higher end air or liquid coolers. Once you get past that stage you get to the world of extreme overclocking, 12 The OverClocker Issue 43 | 2018 where hobbyists emp loy dry ice (-78.5’C), liquid nitrogen (-196’C) or even liquid helium (-269’C) to further lower the temperature of these select components. Operating components at these low temperatures has a secondary effect, which is that you can operate a GPU for example, at a higher frequency and employ higher voltages than you could using a standard air or AIO liquid cooler. As such, these extreme cooling measures are key to competitive overclocking at this level. While Liquid Nitrogen cooling does have its disadvantages, it is certainly not practical for day to day use, in as much as the power unit of an F1 car is not suitable for everyday use. At this level however, liquid nitrogen makes possible new levels of performance that is otherwise unattainable using every day cooling mechanisms. Competitive overclocking at GOC and such events however, isn’t about getting down to the lowest temperature possible. Care must be taken to keep temperatures within the correct range for operation for a stable system. It is this delicate balance, monitoring and dealing with frost build up, and more which the highly skilled
