Hello, just switched over to the Classified K and I have a 970 evo (works fine) and a 1Tb WD Blue SATA M.2 (not shown in bios or windows, WD's ssd utility looks like it tries to find it but it crashes). I've fiddled around in the BIOS and don't exactly know what's going on... I thought this board supported SATA M.2's?
Specs:
i7 9700k
z370 Classified K on 1.12 BIOS
32 Gb Crucial RAM
