Intel intends to gradually cover the loophole that allows to overclock Skylake-S processors without the free multiplier at the expense of increasing the frequency of the base generator. This systematic campaign will be implemented with the acquiescence of motherboard manufacturers are now forced to release a BIOS update to combat the problems of Skylake processors, caused by the launch of the utility Prime95. Some of these updates just will deprive the owners of features overclocking Skylake-S processors.
However, some BIOS update will be happy to leave the possibility of increasing the frequency of the base generator and fix the vulnerability associated with Prime95 and other utilities.
