With Kaby Lake yet to see a retail release we’re already getting extreme overclocking results and it appears they seem to overclock reasonably well. There’s always guys who that it a step further, and with the help of some exotic cooling, you are bound to achieve success, in this case 7 GHz.
So with a Core i7-7700K sample at hand, overclocker Allen “Splave” Golibersuch reached that 7 GHz clock frequency. There’s a few things that need to be said though, first he had to disable HyperThreading to maintain stability, secondly, it was only on two cores as he had to disable two out of four of them to achieve a stable 7 GHz.
The 7700K was mounted on an ASRock Z170 OC Formula motherboard and managed that 7022.96 MHz with a combination of a multiplier of 69x with a 101.78 MHz base-clock.
The voltage needed was a scary 2.00v. Add the fact that two cores were deactivated the cpu managed to do a PiFast run in 9.02 seconds and SuperPi 2M in 4m 20.25 seconds. WPrime finished in 2.953 seconds and 32M run and finally wPrime 1034M in 1 minute and 33.171 seconds.
The blog post of the overclocker did not mention cooling, we assume it was dry ice or liquid nitrogen based on the massive 2.00 Volts on the CPU core.
