(knock on wood). So if you had similar problems to what I had, this might be the BIOS version for you to try updating again. The USA support page for this board.

I had contacted MSI support twice for two of those BIOS updates and they thought it was some sort of regression in the BIOS code. I just now tried 7E16v1C7 that came out on 10-22-2025. It appears to be working fine!
