Overclocking

I was pleasantly surprised when overclocking with the ASRock X299 Killer SLI/ac. My standard testing of simply changing a couple of options in BIOS and watching what the board does was automatically met with great results, although the provided voltage to the CPU could have been a wee bit lower (which isn't that big of a deal as it can be adjusted manually easily enough). XMP support worked well, and I was able to get 4000 MHz memory working with relative ease as well, although my particular CPU does require a drop in CPU clocks when pushing memory over 3866 MHz. ASRock's digital VRM design present on all of their X299 motherboards has proven itself when pushing those maximum CPU clocks, every time, even with only 11 phases instead of 13.
