Bios + DMI . If it doesn`t work check for loose ram slot pins

DMI is not at the right offsets.

Unfortunately none ot these bioses didn't work for me. Pins in ram slots and also ram chips are checked and good.
Is there antything else to check, or APU is dead?

You can try a few older bios versions. Read the guides and you can find and extract them yourself
