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.

Questions about this item
Will a Ryzen 5000 series CPU run the primary PCIe slot at 4.0 x16?
Yes, Ryzen 5000 and 3000 series processors enable PCIe 4.0 x16 mode on the top slot, while G-series CPUs run it at 3.0 x16.
Can I populate all four memory slots with 32 GB modules for 128 GB total?
The board supports up to 128 GB across four DDR4 slots, so four 32 GB unbuffered DIMMs will reach the maximum capacity.
Does the M.2 slot accept SATA as well as PCIe SSDs?
With a Ryzen 5000 or 3000 series CPU the M.2 connector supports both SATA and PCIe 4.0 x4 or x2 drives; G-series CPUs limit it to PCIe 3.0.
