Over­clock­ing

We first tweaked the CPU mul­ti­plier ra­tio and raised the volt­age ac­cord­ingly. Af­ter as­cer­tain­ing that the achieved clock speed was sta­ble, we then pro­ceeded to in­crease the BCLK value to get smaller over­clock in­cre­ments. This also en­abled us to take ad­van­tage of the new over­clock­ing ca­pa­bil­i­ties of Sky­lake CPUs, which al­low a wider range of BCLK val­ues. Chang­ing the BCLK val­ues also over­clocks the RAM, so we throt­tled the speed ac­cord­ingly to main­tain sys­tem sta­bil­ity.

The ASUS moth­er­board was the most ca­pa­ble over­clocker here and we man­aged to hit a top speed of 4.83GHz, which trans­lated to around a 17 per­cent im­prove­ment over de­fault speeds. The ASRock and MSI moth­er­board also per­formed de­cently, com­ing in se­cond and third, re­spec­tively. Un­for­tu­nately, the Gi­ga­byte moth­er­board didn’t live up to its whop­ping 22-phase power de­sign at all, man­ag­ing a top over­clock of just 4.66GHz from our tri­als.
