It's bad luck on your end. I have 3 AMD-based "desktops", never had a single problem with any of them. I just throw whatever memory in and it just works. These are being used more as servers than desktops, with large RAID arrays, HBA cards, tape drives, etc. They're consumer-level systems - Ryzen 7 5700G, Ryzen 5 2600, Ryzen 7 7800X3D.
