There is not a Command Rate option setting yet in any ASRock Ryzen boards. It will be coming in a few weeks, or should be, once the new AMD AGESA CPU microcode has been added in a UEFI/BIOS update, along with new memory timing settings, including Command Rate.

Have you tried running your memory at 2133 for a few days and see if you still get random BSODs?

If you download the CPU-Z program, run it and click on the SPD tab, it will show you all the standard memory timing values programmed into it. That will show you what latency values are valid at each speed. There are only four memory timing parameters in the UEFI/BIOS now, which is very minimal, so it should be easy to match and set values.

Your memory is rated for 2400 at 1.2V, but a small increase to 1.25V won't harm anything. Ryzen systems seem to have trouble getting to the highest rated speed of some memory models, and since your memory is only rated up to 2400, it might have a little instability

You did not mention installing any drivers after installing Windows. Did you at least run the AMD All in One driver installation package?
