Liquid nitrogen-cooled Haswell chip hits 6.5GHz
The guys from Asrock shows how a 3.5GHz Intel Core i7-4770K CPU can be
overclocked to 6.5GHz using a sub-zero cooling setup at Computex.
TAIPEI–The CPUs in most computers are usually cooled using a
combination of fans and heatsinks. PC enthusiasts go one step further by
using liquid cooling as shown in the rig above. This allow them to push
the processor to run beyond its normal operating speeds so as to
achieve better performance, without overheating the chip.
The folks at Asrock cools a Haswell chip using liquid nitrogen.
Professional overclockers, however, use sub-zero cooling to achieve extreme processing speeds. In
most setups, liquid nitrogen is used to chill the processor and has to
be topped up regularly, while Vaseline is applied to the surrounding
microchips. This prevents them from short-circuiting due to
Using this technique, the team from Asrock managed to overclock a 3.5GHz
Core i7-4770K to 6.5GHz at Computex. This high-end Haswell processor is
paired with an Asrock Z87M motherboard, which supports 2,800MHz DDR3
memory modules (RAM). In comparison, Intel is officially supporting RAM
modules of up to 1,600MHz.
