Asus sponsors an event known as Absolute Zero, which basically gathers all the top class overclockers from the world, and during the recent event gathering, a German overclocker managed to take Intel Core i7-7700K to 7.2GHz clock speed.
The 7.2GHz clock speed was achieved through liquid helium cooling method that costs around €4,000 euros for 100 liters. The code name of German overclocker is ‘der8auer’. You can check out the recorded video below.
Asus’ Absolute Zero events focus on processors that can function at very low temperatures. With that being the case, participating overclockers not only turn to liquid nitrogen, but also liquid helium. It’s more expensive but is also cooler at around -269C (about 70C lower than liquid nitrogen).
German overclocker ‘der8auer’ explains in the video that the first part is to get used to the hardware. Asus has a team of engineers that attend these events and who can offer support. However, the overclockers are not given any guidance on things like how far they can increase the voltage.
So, after getting used to the new motherboards, overclockers embark on playing with the CPUs. But, amidst all the voltage tests and cooling tests, some of the hardware gets destroyed throughout the process.
He further adds that overclocking process is as hectic as it gets. There is a lot of trial and error involved in finding out voltage limits. Overclockers also have to figure out which CPUs work best with certain cooling methods and benchmarks. This can take days of testing.
German overclocker ‘der8auer’ finally concludes that he managed to push Intel Core i7-7700k to 7.2GHz by leaving all cores enabled and leaving Hyper Threading turned on.
However, it must be noted that this usually is not the case when doing extreme overclocking, but regardless, this is what worked for him in this case and took Intel Core i7-7700K to 7.2GHz.
