Guy Overclocks Intel’s Core i7-7700K Kaby Lake Beyond 7GHz Barrier


Short Bytes: A professional overclocker named Allen “Splave” Golibersuch has been able to overclock a 7th Generation Intel Core i7 7700K processor to a clock frequency of 7022.93 MHz. He disabled HyperThreading technology and two physical cores of the CPU.

The 7th generation Intel Core processors – based on the 14nm architecture called Kaby Lake – promise 4K out of the box. Intel announced the processors a couple of months ago, and it’s highly likely for desperate overclockers to test the real potential of these next-generation CPU’s.

A yet-to-be-launched Intel Core i7 7700K desktop processor was put on the test bed by overclocker Allen “Splave” Golibersuch for the Russia-based website OCLabs. He bumped the CPU clock frequency to a staggering 7GHz after combining it with an ASRock Z170 OC Formula motherboard and using liquid nitrogen as a coolant.

For the processor, having a base-clock of 101.78 MHz, a multiple of 69x was applied to push the CPU past the 7GHz milestone and achieve a clock frequency of 7022.96 Mhz.

Splave kicked out a bunch of key features. He disabled Hyperthreading and two cores of the quad-core i7 7700K. He set the Vcore voltage to 2V, which is around 1.2V depending on the processor.

Regarding benchmarks, the overclocked CPU was a breeze. With the overclocked speed, the CPU is currently a world record holder for the SuperPi 32m benchmark with 4m 20 sec calculation time. SuperPi asks the CPU to calculate the value of Pi to a particular number of digits. The CPU ended up with 2.953 seconds for wPrime 32M and 1m 33.171 sec for wPrime 1024M.
