Hi Neil, here are few suggestions from fellow MSI MEG/2990WX owner:
- Did you update to latest bios ?
7B92v13 https://www.msi.com/Motherboard/support/MEG-X399-CREATION#down-bios- Are you running latest chipset drivers ? Windows doesn't install them correctly.
https://www.msi.com/Motherboard/support/MEG-X399-CREATION#down-driver - Keep your memory at 2933 CL15/16. 4x 16 GB
could be stable at 3200, but it would require higher end bins and those are expensive (3200 CL16 is common average Hynix/Micron). The supplied XMP profile for 3200 is only stable on Intel x299.
- But if your PC is freezing at default 2133, then it isn't memory controller issue. Since they are also fully detected, it's not issue with seating either. But you can always try with single DIMM for a test.
- Did you try different GPU if you have on lying around? Is your GPU connected with auxiliary PCIe power cables as well?
