Among today's attractions at ASRock's booth at COMPUTEX 2013 was the three 'Masters of Overclocking' that showed how a 3.5GHz Intel Core i7-4770K CPU can be overclocked to 6.5GHz using a subzero cooling setup.
The overclockers used liquid nitrogen to chill the processor and Vaseline was applied to the surrounding microchips in orfer to avoid short-circuiting due to condensation.
The team managed to overclock a 3.5GHz Core i7-4770K to 6.5GHz. The Haswell chip was installed on an Asrock Z87M motherboard, which supported 2,800MHz DDR3 memory modules (RAM).
Previously, an ASRock Z87M OC Formula and Nick Shih, a master of overclocking and his friend John Lam from HKEPC OC, had broken a world record by overclocking a single Team Group - Xtreem-LV-2666 DDR3 4G memory module to an unearthly 4095MHz on the new motherboard.
