Windows OS Configuration = CSMUsually the m.2 closest to the socket. on x570 you'll have one with pcie lanes direct to the cpu and one or two that go through the chipset. Not sure it actually matters, but that's the one that worked for me.

Thanks for your input.

DDR timing defaults with BIOS 188.8.131.52 are horrible.
Had to toss my previous timings.
