Despite the lack of official support for motherboards on the Intel Z170 and Z270 Coffee Lake-S (Refresh) chips, professional overclockers continue to experiment in that direction.
It was found that thanks to the modified UEFI firmware on the old motherboards, the six processors can be used in the LGA1151 design. Finnish enthusiast Luumi decided to go further and recently released a video about eight-core Intel Core i9-9900K overclocking process at the ASRock Z170M OC Formula.
We point out that this board proved to be one of the best solutions for these purposes and helped put more than one overclocking record in tandem with a six-core Intel Core i7-8700K.
Ultimately, Luumi managed to overclock the Intel Core i9-9000K at 5.5 GHz, armed with a liquid cooling system. For system stability testing, Prime95 and Cinebench R15 were used. By the way, in the last benchmark we managed to achieve more than 2,400 points.
Anyone who wants to repeat their experiment, the Finnish overclocker is called VRM heating monitoring. Eight core-energy refreshment cores significantly overrides those processors for which this motherboard is designed.
Recall that Intel itself explains the incompatibility of the Coffee Lake-S processor with older power-hungry boards, which has led to a change in the allocation of some LGA1151 contact plates. Moreover, the budget products on the H110 chipset, as well as the Z170 and Z270 logic sets, referred to the masters of sports overclocking, were out of business.
