So according to the manual for the ASRock AB350 Pro 4 MB(and others) the maximum memory speed with 1 module is 2667, 2 modules is 2400-2667 and 4 modules is 1866 - 2133. See:

https://www.asrock.com/mb/AMD/AB350%20Pro4/index.asp#Manual

Is this normal for AMD? Normal for B350 chipset? Normal for ASRock? Motherboard got decent reviews, and I'm only planning on 2 modules for now, but would like it to support expansion in the future.

Thanks for the help!
 
Solution
Completely normal for the Chipset/AMD.

That's just "official" spec though and not to say higher speeds cannot be achieved manually/via XMP.
