cpu noteMSI's spec page lists 1st-3rd Gen Ryzen only. AMD's AM4 chipset table lists Ryzen 5000 as supported on B450, and AMD notes support may require a BIOS upgrade; check MSI's CPU support list for the minimum BIOS before installing a Ryzen 5000 CPU.

Good to know
  • AMD: not all processors are supported on every chipset, and support may require a BIOS upgrade. Check the board maker's CPU support list for the minimum BIOS before buying.
  • Ryzen 5000 runs on X570, B550, A520 and on 400-series boards (X470, B450) per AMD's chipset table, but a 400-series board whose BIOS predates Ryzen 5000 must be updated before it will boot one.
  • On 300-series boards (X370, B350, A320) AMD marks Ryzen 5000 as 'Selective Beta BIOS update needed' - only some boards got that BIOS.
  • AM4 processors do not fit AM5 boards and AM5 processors do not fit AM4 boards.
  • Low-profile coolers that replace the stock AMD backplate (e.g. Noctua NH-L9a-AM4, NM-AM4-L9aL9i kit) fit AM4 but not AM5.
  • Noctua notes some AMD boards violate AMD's 96x114 mm keep-out zone; check RAM and VRM-heatsink clearance with large coolers.
