I just received a brand new MSI X470 Gaming Pro motherboard, AMD 2600X CPU, and Corsair LPX Vengeance DDR4 (CMK16GX4M2B3200C16) today.
I'm going to build a system for my kids.
Anyhow, I removed an Asrock x370, AMD 1600, with Corsair LPX Vengeance DDR4 from my tower. I then installed the above components in my tower. All over components remained the same (850W PSU, XFX 5700XT GPU, hard drives, etc).
The motherboard, and Windows, don't always recognize all 16GB of RAM. It's odd. The board came with a Bios from Jan 2019 installed. The system booted up with 7.9GB of Total RAM. The BIOS does not allow for settings for memory mapping that I can find. So I swapped the DDR4 DIMMS around. Suddenly I now have 16GB. Tried playing an existing install of Red Dead Redemption 2 (obviously I installed all the lastest drivers from MSI's site, updated my GPU driver to the latest, etc). I can play for about 2 minutes and the game crashes. So I tried another working game. It crashes 2 minutes in as well.
So I took the Corsair DDR4 3000 dimms out of my other motherboard. Put those in this new system. Same issues with the BIOS not always seeing 16GB.
It seems if I set the BIOS to "default settings" it only sees 8GB of RAM. But if I select an XMP profile or manually set frequency it then sees all 16GB. (Default sets RAM at 2133MHZ).
Windows has blue screened on me a few times giving Stop Code: "Memory Management" and "IRQL Less than or Equal".
I've updated to the latest E1 BIOS from MSI. Doesn't fix the issue. So I downgraded to the D1 BIOS. Doesn't fix it either.
Bought the parts through Amazon. So I can probably send them back if need be. But I've never run into an issue like this before. Not sure what else to check.
