Intel Core i7-7700K gets overclocked beyond 7 GHz

Professional overclocker Allen “Splave” Golibersuch has managed to overclock a sample Intel ‘Kaby Lake’ Core i7-7700K processor to beyond 7 GHz. However, it should be noted that the overclocker managed to achieve a stable 7 GHz+ overclock only by disabling HyperThreading as well as two of the four physical cores of the processor. The overclocker hasn’t mentioned anything regarding the cooling in his blog post, so it isn’t clear if he used dry ice or liquid nitrogen to overclock the Core i7-7700K.

If you’re curious, the 7022.96 MHz overclock was achieved on an ASRock Z170 OC Formula motherboard with a 69x multiplier and a base-clock of 101.78 MHz. Unsurprisingly, it took a high 2.00V Vcore voltage to achieve the high overclock. As for performance numbers, the processor finished PiFast in 9.02 seconds, SuperPi 32M in 4 minute 20.25 seconds, wPrime 32M in 2.953 seconds, and wPrime 1024M in 1 minute 33.171 seconds.

The overclocked Core i7-7700K, combined with an ASUS GeForce GTX 1080 STRIX OC graphics card, managed a score of 643,316 points in Aquamark and 86,798 points in the 3DMark 05 graphics benchmark.

While most users will most probably never considering overclocking their Core i7-7700K to 7 GHz, it does show that the 7th Gen Core i7 processors do have excellent overclocking potential. As revealed by numerous tests published on the web recently, ‘Kaby Lake’ processors do not boast of any significant IPC gains over their ‘Skylake’ counterparts. So the main reasons to upgrade to ‘Kaby Lake’ would be higher overclocking potential and dedicated support for 4K HEVC encode/decode at 10-bit depth.
