Intel Core i7 7700K Overclocked to 7 GHz

Published by


As you guys know we tested the Core i5 7600K already, Kaby Lake  shows little IPC gains.  They do overclock reasonably well. There's always guys who that takes 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.

He popped that proc on an ASRock Z170 OC Formula motherboard and thus managed that 7022.96 MHz with a combination of a multiplier of 69x with a 101.78 MHz base-clock.

The voltage needed ? Well, you can get scared now .. it was 2.00V. The 7700K with it's two cores active managed to do a PiFast run in 9.02 seconds and SuperPi 2M in 4 minutes 20.25 seconds. wPrime finished in 2.953 seconds 32M run and last but not least wPrime 1024M in 1 minute 33.171 seconds. 

The blog post of the overclocker did not mention coolling, we assume it was dry ice or liquid nitrogen based on the massive 2.00 Volts on the CPU core.
