Discussion about Ryzen 3 3000 (Zen 2)
The Ryzen 3 3000 CPUs from the Zen 2 lineup should work on B450-M motherboards without needing a BIOS update. You can go ahead with your plan to get a 3300X and pair it with a budget-friendly B450-M board.
Request the shop to refresh the BIOS—most handle it without charge. Others demand a small fee, usually around ten dollars.
