My story is long and drawn out. To sum it up I have to identical kits of the 32Gig Dominator Both branded the same:
CMT32GX4M2C3200C16
But when both kits are installed, iCue showed they crashed and never recovered correctly. Red Triangle and freezing. But was able to run XMP on them on an ASUS x570 board. Fast Forward to a Motherboard swap. Now an MSI X570 board, XMP would fail and the RGB would fail. Submitted a ticket and doing research.
So I found a Reddit post about XMP problems. basically it said to check the PHYSICAL version numbers on the RAM module itself. One kit is version 4.31 with Samsung Chips and the other kit is version 3.31 with Hynix Chips. So I began checking possible combinations, each individual kit did what it was supposed too. Run the applied XMP profiles along with no problems with iCue.
Till today. I have the Hynix version 3.31 kit in my media server and one stick the RGB failed stuck on 2 red LED's at either end.
Possible a faulty stick was all my problems? But it would not explain the XMP profiles working with the individual kits on all my boards. But XMP only failing on just the MSI x570.
FYI: Media server is an MSI B450I board.
