As the title says. My daughters 5600G refuses to work on her new B550m Mortar motherboard. When booting up the PC stucks on a black screen and the CPU debug led is solid red. Both the CPU and the motherboard works. The 5600G works fine on a A520 motherboard, and the B550 motherboard works with both a 3700X and a 5900X. I even tried 3 different sticks of RAM. All 3 modells works with all parts as long as i don't pair the 5600G with the B550m mortar. So all the parts does work as intended minus this combo. The BIOS version on the B550m Mortar is 7C94v19 from 2021-12-20. So it definitely has support for the 5600G. Is this a common issue?
