ASRock turns to an external clock generator for BCLK overclocking
 

ASRock just won't do what Intel tells it to. The company may have issued BIOS updates that removed its SkyOC base-clock (or BCLK) overclocking features from many of its motherboards, but it's not abandoning the locked-CPU overclocking dream just yet. This time around, the company is taking the battle to the hardware. Its Fatal1ty H170 Performance/Hyper and Fata1ty B150 Gaming K4/Hyper boards both rely on an external clock generator for the BCLK signal. This generator appears to allow for base-clock overclocking of locked chips on these motherboards.
