Intel pushes its K-series processors as the only overclocking-friendly chips in its lineup but as usual the motherboard makers found a way around this and over the past couple of months we've seen a string of BIOS updates that unlock overclocking on non-K series Skylake processors.
This may be coming to an end as reports indicate that Intel is preparing the rollout of a new BIOS update that will close this loophole:
According to a report from the Chinese site, Benchlife, Intel is preparing to release a new BIOS update that will stop motherboards from being able to overclock Intel’s non-K processors. Evidence of this has apparently been found in the code for a recent BIOS update, which was rushed out in order to squash a bug with Prime95.
There is no word on when this new BIOS update will be released and officially, we don’t know for sure that it will be, so take this information with a pinch of salt.
