https://forum-en.msi.com/index.php?threads/bios-debug-hex-codes-decoded.263610/ Those codes seem to be for memory, 2 of them, and CPU for the other. You may want to reseat the RAM and CPU to make sure it's not just a poor contact somewhere. Another thing to try is updating the BIOS, that would help clear any sort of data corruption issues with the BIOS itself.

May 26, 2025 -

Is this normal for this motherboard to be displaying debug codes all the time? My PC doesn't seem to crash or anything so I am just confused why it's giving me these codes.

like when I am idle it gives code 54 and 55. which apparently means code 55 "memory not installed" which doesn't make any sense because my PC is running and I am on google chrome right now lol. And Code 54 means memory initialization error.

and when I am gaming its showing codes 57 and 58 which means

57- CPU mismatch
