Overclocking
ASRock's X99 Taichi was slightly more capable in our round of overclocking than MSI's X99A Tomahawk, reaching 4.2GHz on our retail i7 6800K sample. The final overclock is quite mediocre overall but based on our testing on a number of X99 motherboards this is CPU-limited rather than motherboard, as has been the case in most recent Intel CPU generations.
A voltage of 1.275 was needed to hold our overclock stable and ASRock's power management kept power consumption competitive at both idle and load when overclocked.
I was thinking either this one or Fatal1ty…Too tempted with the black and white.
