AM5 board with four DDR5 slots and three M.2 NVMe slots. M2_2 depends on CPU series; M2_3 shares bandwidth with PCI_E2.
Key specifications
| Socket | AM5 |
|---|---|
| Chipset | AMD B650 |
| Memory | DDR5 UDIMM, 4 DIMM slots |
| PCB revision | Not independently verified in this record |
| CPU-less BIOS update | Manufacturer lists a Flash BIOS button |
Do not infer exact CPU support from the socket
The board’s CPU support list and minimum BIOS must be checked for each processor. This record does not invent missing BIOS versions.
CPU support
The manufacturer specification names Ryzen 9000, Ryzen 8000, Ryzen 7000 at series level. This does not establish support for an exact CPU SKU or BIOS. Search the exact CPU SKU in the board’s own support list for a boot verdict.

Memory and QVL
DDR5 UDIMM is the documented module generation and form. An exact kit QVL entry, tested module count and EXPO/XMP speed still need separate confirmation.
M.2 slot map
| Slot | Protocol | Length | PCIe | Condition |
|---|---|---|---|---|
| M2_1 | NVMe | 22110, 2280 | 4.0 x4 | Check manual for additional conditions |
| M2_2 | NVMe | 2280, 2260 | 4.0 x4 | Ryzen 8500, Ryzen 8300 |
| M2_3 | NVMe | 2280, 2260 | 4.0 x4 | Both M2_3 and PCI_E2 run at x2 when occupied together. |
Fit, firmware detection and bootability are separate checks. Heatsink clearance has not been verified here.
Next checks
- Confirm the exact PCB revision on your board.
- Check the CPU support list and installed BIOS.
- Check the exact RAM kit SKU in the QVL.
