EU Gigabyte Mainboard MC12-LE0 Re1.0 AMD B550 AM4 Ryzen

[Civiloid]

I used the CPU and RAM from the QVL, and they worked very well on an Asrock board.

They don't specify since what version of BIOS one or the other CPU/RAM was supported, therefore if you can I'd suggest you to try to update the BIOS to the latest version, or try to find early Ryzen 7000 CPU and also to try to boot it with one stick of RAM installed (consult the manual, but likely you need the black slot that is furtherest away from the CPU). That might help to make it stalbe enough to update BIOS. Oh, also try to find how to reset the BIOS as you never know what settings previous owner had and how they've cleaned them (if at all) before selling.

Thank you for the advice. The board came with the latest BIOS, which is visible in BMC. I also reset the BIOS using a jumper and a battery. Neither method helped. I also tried another RAM stick from my gaming PC, but it had the same result. The seller is very supportive. He said the board was repaired and offered to repair it again, but I don't want to deal with it anymore. The MC12 was known for being sensitive to RAM, and nowadays it's easier to find a compatible motherboard than to select compatible RAM. It will be sent back to Germany today.
