Test System and Driver Set-up

Getting this board up and running even with high-clocked memory to test the board's limits was no problem at all. The ASRock B450 Gaming-ITX/ac claims support for 3466 MHz+, and that "plus" most definitely applies as you can see in the screenshot above, although your processor does need to be capable of handling it, and above 3466 MHz might require some manual tweaking. It's important that these Mini-ITX boards and all boards that claim to be catering to an enthusiast with this platform offer such support as it has long been an established fact that getting the highest-clocked memory you can helps onboard GPU performance, since system RAM is still much slower than proper graphics-oriented GDDR or HBM. Fortunately, the ASRock B450 Gaming-ITX/ac has no problems with what I required of it in this regard.
