Finished Looks

Fortunate for users who aren't too keen on all the RGB LEDs most products seem to have these days, ASRock has kept the provided RGB LEDs on most of its X299 boards to a minimum, with only the chipset cooler getting some LEDs that surround it, giving off a decent glow from underneath the metal cooler.


You only get a minor glow that peeks out from under the VGA card installed into the topmost PCIe slot, giving off just enough light to highlight whatever M.2 device you may have installed in that upper M.2 port.

Test System

The ASRock X299 Killer/ac boots up with very standard Turbo profiling. Once again we see a reduced BCLK here at default, like we did with the ASRock X299 Gaming i9. Memory compatibility is actually pretty good with this board. I did test with the most recent beta BIOS, v1.30A, available for download on the board's products page at the time of writing.
