CMW32GX4M4Z3200C16 DOCP won't POST


Recommended Posts

Hi all,


I recently completed a new build with the following specs:


  • Ryzen 9 3900X
  • Asus Strix X570-F Motherboard
  • Corsair Vengeance RGB Pro 32GB (4x8GB, CMW32GX4M4Z3200C16, Ryzen compatible)
  • RTX 3080


My issue is that I can't seem to get the RAM to run at it's XMP/DOCP speed of 3200MHz. The PC will reboot but not POST, with the DRAM error LED illuminated. I then have to do a CMOS reset to get going again.


The RAM defaults to 2666MHz speed otherwise.


I have attached a screenshot from Thaiphoon Burner and I suspect that it is misreading the kit's IC based on the XMP timings. It looks more like Samsung C-Die than B-Die.


Any suggestions on how I can get this kit working at it's rated XMP speeds? I did try to get timings from DRAM Calculator for Ryzen, but it doesn't support Samsung C Die.
