We’ve said this a number of times already, but we’ll say it again, the Intel Core i7-6700K is a beast of a CPU.
Not only is it faster than its predecessor, the i7-4790K, as well as the much pricier i7-580K at stock clocks, but it’s one heck of an overclocker.
Having already reached 5.2 GHz with air cooling and 6.5 GHz with liquid nitrogen, Chi-Kui Lam, a professional overclocker, has reached 7 GHz (or just under) with liquid nitrogen.
6998.88 MHz is a massive 74.97% improvement over the i7-6700K’s 4 GHz stock clock, and no small feat to achieve.
In fact, it took 1.888 volts, an additional 0.688 V, and disabling Hyper-Threading as well as all but one of the cores to make it happen.
That’s a severely gimped processor by all accounts, but there’s no denying how impressive Lam’s achievement is.
To make it happen, he used an AsRock Z170 OC Formula motherboard, G.Skill’s Ripjaws 4 DDR4 memory and a 1300W PSU. Curiously, Lam chose not to use G.Skill’s Ripjaws 5 or Trident Z DDR4 memory.
Either way, he’s broken the record for the i7-6700K, but he’ll forgive us if we express our desire for someone to break that record and break the 7 GHz barrier.
