Socket AM5 for Ryzen 9000 series

This motherboard targets builders who want a compact M-ATX board that accepts AMD Ryzen 9000, 8000 and 7000 desktop processors. The B850 chipset unlocks PCIe 5.0 lanes for graphics and storage while keeping the footprint at 24.5x24.5cm. Onboard WiFi6E and a 2.5Gbps Ethernet port handle networking without extra cards.

192GB DDR5 across four slots

Four 288-pin DDR5 slots support up to 192GB of memory with AMD EXPO profiles up to 7000 MT/s. Dual-channel topology keeps latency low when all slots are populated, and the board validates 4800-7000 MT/s overclocked speeds on Ryzen 8000 and 9000 series CPUs. This capacity ceiling is the decisive spec for workstations that need large datasets in RAM.

19-phase power delivery under load

The 19-phase VRM feeds the CPU socket through extended workloads without throttling, backed by four 4-pin fan headers for active cooling. Three M.2 slots — one PCIe 5.0 x4 and two PCIe 4.0 x4 — sustain high throughput for sequential reads and writes. Rear I/O includes HDMI, DisplayPort, a 10Gbps Type-C link via the Type-E header and legacy PS/2 and COM ports.

Questions about this item

What does the 7000 MT/s DDR5 rating mean once the board is in a real machine?

The board supports DDR5 up to 7000 MT/s via AMD EXPO profiles, so compatible kits can run at that speed without manual tuning when installed in the four 288-pin slots.

How does the PCIe 5.0 M.2 slot limit drive performance in practice?

One M.2 slot is wired for PCIe 5.0 x4, giving a theoretical ceiling of roughly 16 GB/s, while the other two M.2 slots operate at PCIe 4.0 x4 speeds.

What does the board need to fit and mount in a case?

It uses the M-ATX form factor measuring 24.5 cm by 24.5 cm, so any case that accepts micro-ATX motherboards will accommodate it.
