Biostar B550MH AM4 DDR4 Micro-ATX Motherboard
The Biostar B550MH AM4 DDR4 Micro-ATX Motherboard steps up from entry-level AM4 boards with the AMD B550 chipset, PCIe 4.0 graphics and storage support, and dual-channel DDR4 memory reaching high overclocked speeds. It suits a gaming build or a productivity desktop where a fast graphics card and a PCIe 4.0 SSD matter, in a Micro-ATX case.
Key Specifications
- AMD B550 single chip architecture with AM4 socket for 3rd Gen Ryzen (Matisse and Renoir) and 4th Gen Ryzen (Vermeer) processors, with support for future Ryzen processors via BIOS update
- 2 x DIMM DDR4 slots, DDR4-4933+(OC), 4800(OC), 4600(OC), 4400(OC), 4000(OC), 3800(OC), 3600(OC), 3200, 2933, 2667, 2400, 2133 and 1866, up to 64GB

PCIe 4.0 Graphics and M.2 Bandwidth on a Compact Board
The B550MH's headline advantage is bandwidth: a PCIe 4.0 x16 slot for a modern graphics card and a PCIe 4.0 M.2 socket for a high-speed NVMe drive give a mid-range gaming PC the same fast lanes found on larger boards, while the four SATA ports still cover bulk storage.
- Pair the board with a Matisse Ryzen processor to unlock PCIe 4.0 graphics and storage speeds
- Install dual-channel DDR4 memory up to 64GB across the two DIMM slots
- Fit a PCIe 4.0 NVMe SSD in the M.2 socket for the operating system and games
- Install a graphics card in the PCIe 4.0 x16 slot for gaming or GPU work
- Expand with SATA SSDs or hard drives on the four SATA III connectors
