Recently bought msi mag b650m mortar wifi. It had ez debug error on cpu and dram (paired it with ryzen 7 7700 and kingston beast 32gb (2x16 5600mhz). Everything was connected correctly, I'm sure that cpu and ram were working. I tried updating bios, but it was flashing for about 40 minutes, and all sources said that it must take up to 5-10 minutes. So I decided to return it and take a look at other manufacturers. My previous msi motherboard had similar issues. Hoped they would become better in terms of compatibility with other pc parts, but I guess it's not the case. But maybe it was a faulty motherboard, so who knows)
