Problem with RAM slot connection.
Problem with RAM slot connection.
Hey there, I'm facing a tricky problem with my MSI MPG Z790 Carbon WiFi board. After installing new CPU, my monitor wouldn't show anything, and the board displayed error code 55 (Memory not installed). What I did: checked various RAM sticks and slots, found one slot isn't connecting properly. I let the PC run for about 15 minutes to warm up, then restarted with memory training enabled. RAM was detected and the system booted fine. But when I shut it down completely and waited for cooldown, the issue came back. Appreciate any help!
