Overview
The GIGABYTE B550M Gaming X WiFi 6 is a Micro ATX motherboard built on the AMD B550 chipset for the AM4 socket, offering a capable platform for AMD Ryzen 3000, 4000, and 5000 series processors — including G-Series APUs. Designed with the DIY gaming builder in mind, it balances modern connectivity and solid power delivery in a compact 24.4 cm x 24.4 cm form factor that fits a wide range of mid-tower and Micro ATX cases. Power delivery is handled by a digital twin 5+3 phase VRM solution paired with VRM Thermal Armor Advanced, helping maintain stable voltages under sustained loads. Four DDR4 DIMM slots support dual-channel configurations with up to 128 GB of system memory (32 GB per DIMM), and speeds spanning DDR4 2133 through 3200 MT/s including XMP profiles. ECC unbuffered memory is also supported for workstation-adjacent use cases. Storage options are versatile: two M.2 connectors (type 2280) cater to both SATA and NVMe drives, with the CPU-attached M.2 slot supporting PCIe 4.0 x4 speeds on Ryzen 5000 and 3000 Series processors. Four SATA 6 Gb/s connectors round out the storage suite, and RAID 0, 1, and 10 configurations are available for both NVMe and SATA arrays. Wireless connectivity is provided by a Realtek Wi-Fi 6 RTL8851BE module with Bluetooth 5.3, covering 2.4 GHz and 5 GHz bands at 802.11ax with 80 MHz channel support. A WIFI EZ-Plug header simplifies antenna installation. Wired networking uses a Realtek GbE LAN chip for 1 Gbps connectivity. The primary PCIe x16 slot (CPU-attached) supports PCIe 4.0 x16 on Ryzen 5000/3000 non-G processors and features GIGABYTE's PCIe UD Slot reinforcement design with EZ-Latch for tool-assisted GPU removal. Display output is available via integrated AMD Radeon graphics using the rear HDMI 2.1 port (up to 4096x2160 @ 60 Hz) and DisplayPort 1.4 (up to 5120x2880 @ 60 Hz), both with HDCP 2.3 and HDR support. Audio is managed by a Realtek ALC1220 CODEC with High Definition Audio and up to 7.1-channel support. USB connectivity includes four USB 3.2 Gen 1 Type-A ports on the rear panel, plus a front-panel USB Type-C header (USB 3.2 Gen 1). RGB and ARGB headers (two each) plus a CPU cooler LED header allow addressable lighting control via GIGABYTE RGB Fusion software.
