Technical specifications.
Platform & memory
- Chipset / socket
- AMD B850 / AM5
- CPU support
- AMD Ryzen 9000, 8000 and 7000 desktop processors
- Memory
- 4 × DDR5 UDIMM / up to 256GB / dual channel
- Memory tuning
- Up to 8200+ MT/s OC / AMD EXPO
- Form factor
- Micro-ATX / 243.84 × 243.84mm
Expansion & storage
- Expansion
- PCIe 5.0 x16 / PCIe 4.0 x4 / PCIe 3.0 x1
- M.2 slots
- 1 × Gen5 x4 / 1 × Gen4 x4
- SATA
- 4 × SATA 6Gb/s
Connectivity & audio
- Networking
- Realtek 8126VB 5G LAN / Wi-Fi 7 / Bluetooth 5.4
- Rear USB
- 3 × USB-A 10Gbps / 2 × USB-C 10Gbps / 3 × USB-A 5Gbps
