That's what I would've thought too but the system would stay on the orange light for about 2 minutes before shutting itself off.Flashed to a 2 month old BIOS (3024 for X670E-I), which posted fine. Kept moving to a newer and newer BIOS and eventually ...

Running a similar setup, X670E-I on BIOS 3057, moved from 7950X3D to 9800X3D. System won’t post no matter what I try.
