GIGABYTE B550M GAMING X WIFI6 AMD motherboard

Socket AM4 B550 micro-ATX board

The GIGABYTE B550M GAMING X WIFI6 is a micro-ATX motherboard built on the AMD B550 chipset for Socket AM4 processors. It supports Ryzen 3000, 4000G and 5000 series CPUs, including G-series APUs. Four DDR4 slots accept up to 128 GB of memory at speeds up to 3200 MHz. Integrated Wi-Fi 6 and 1 Gbps LAN provide wireless and wired connectivity.

Builders needing one PCIe 4.0 x16 slot and one M.2

This board suits builders who want a single PCIe 4.0 x16 graphics slot and one CPU-attached M.2 2280 slot that runs at PCIe 4.0 x4 with Ryzen 5000 or 3000 series CPUs. A second x16-sized slot runs at PCIe 3.0 x4 and a PCIe 3.0 x1 slot rounds out expansion. Four SATA 6 Gb/s ports support RAID 0, 1 and 10 for both NVMe and SATA drives. Users requiring multiple M.2 slots or more than one PCIe 4.0 x16 slot should look at full-size ATX alternatives.

One CPU-attached M.2 2280 slot at PCIe 4.0 x4

The decisive specification is the single M.2 connector (M2A_CPU) that delivers PCIe 4.0 x4 bandwidth only when paired with a Ryzen 5000 or 3000 series processor. With Ryzen 5000G, 4000G or 3000G APUs the same slot falls back to PCIe 3.0 x4. If your build depends on two high-speed NVMe drives or a second PCIe 4.0 x16 lane, this board will not meet that requirement.
