ASRock Uses External Clock Generators to Circumvent Intel non-K BClk OC Limits
 

ASRock discovered a novel workaround to Intel's recent base-clock overclocking restrictions for its 6th generation Core "Skylake" processors. The company announced the Fatal1ty H170 Gaming K4 HYPER and Fatal1ty B150 Gaming K4 HYPER motherboards, which are based on a common PCB, but differ with chipset - H170 Express and B150 Express. The two use an external clock-generator chip to give cadence to the CPU, circumventing the on-die clock-generator Intel has been using for the past several generations of Core processors.

With this contraption, you can increase base clock frequency on non-K Core processors in fine increments of 0.0625 MHz, as well as tweak memory clock. Its star attraction aside, the two "HYPER" series motherboards offer mid-range feature-sets, that are nearly identical to those of the Fatal1ty H170 Gaming K4 and the Fatal1ty B150 Gaming K4 boards.
