World record overclocking requires an optimized motherboard and liquid nitrogen cooling. The overclocker that goes by Hicookie has combined both with LN2 cooling and the Gigabyte Z590 AORUS TACHYON motherboard to overclock the Intel 11th gen Core i9-11900K to 7314 MHz, currently holding the world record.

The Gigabyte Z590 AORUS TACHYON motherboard was designed to overclock with many features tailored to overclockers. The most important, the power delivery, is a 12+1 direct phases solution that delivers 1300 amps with the DrMOS power stage design. On top of that, the VRM also implements a full tantalum capacitor matrix for a better overclocking experience.
