It should have been running and trying to boot at JEDEC 2133 MHz all along since I was starting from a fresh CMOS cleared state. It’s just basic Micron E-die that my 3700x can OC to 3600+ MHz with tightened timings. So I thought about buying some new ram at MC and trying that but feel like I shouldn’t have to, given that this stuff is quality.Have you tried a different brand of DDR4-3200 memory? What about if you use the default (non-XMP) setting for the memory in the BIOS, is it stable then on the 5900x?
Definitely, always started from a fresh cleared CMOS state. I just checked and the memory is not on the qvl for either Zen 2 or Zen 3 on either board — but if the IMC can’t run or even boot decent standard Micron E-die even at 2133 :/ think it’s probably going back unfortunately. Maybe I’ll exchange if they have one, otherwise just stick with what I have. Works great and quite fast.Have you tried to reset CMOS?
Is the RAM on your mobo compatibility list (even if it worked before, if it isn't on the QVL list, then it's possible -- though admittedly not probable -- that it will work with some hardware configurations and not others)?
