One ambitious overclocker has managed to push a sample version of Intel’s Core i7-7700K beyond the 7GHz threshold, with the aid of some liquid nitrogen, reports TechPowerUp. Professional overclocker Allen “Splave” Golibersuch managed the impressive feat by disabling hyperthreading and two of the chip’s four cores, increasing the clock multiplier to 69x, a base clock of 101.78MHz, and pumping up the Vcore voltage to 2.00V. The result, when using the liquid nitrogen to supercool the overclocked processor, and paired with an ASRock Z170 OC Formula motherboard, was a stable 7022.96MHz clock.
“The chip crunched PiFast in 9.02 seconds, SuperPi 32M in 4 minutes 20.25 seconds, wPrime 32M in 2.953 seconds, and wPrime 1024M in 1 minute 33.171 seconds. Paired with an ASUS GeForce GTX 1080 STRIX OC graphics card, it scored 643,316 points in Aquamark, and 86,798 points in 3DMark 05,” TechPowerUp explained.
For the sake of comparison, the average desktop processor crunches the wPrime 32M benchmark in around 10 seconds. While many overclockers have expressed their disappointment with the Core i7-7700K’s performance – the lack of IPC gains is a common complaint – crunching the wPrime 32M benchmark in under 3 seconds is an impressive feat.
In our review of the Intel Core i7-7700K, we found the processor to be sold if uninspired, with only minor performance gains, though its video streaming and power consumption capabilities are impressive.
