The GIGABYTE B550M GAMING X WIFI6 is a Micro-ATX motherboard built for AMD Ryzen processors using the AM4 socket. Powered by the AMD B550 chipset, it combines DDR4 memory support, PCIe expansion, dual M.2 storage and integrated Wi-Fi 6 connectivity for gaming and everyday desktop systems.
AMD Ryzen AM4 Platform
The motherboard supports selected AMD Ryzen 3000, Ryzen 3000 G-Series, Ryzen 4000 G-Series, Ryzen 5000 and Ryzen 5000 G-Series processors. Its 5+3 digital VRM design provides processor power delivery, while the motherboard's thermal design supports stable operation under compatible system configurations.
DDR4 Dual-Channel Memory
Four DDR4 DIMM slots support up to 128GB of system memory in a dual-channel configuration. The board supports XMP memory profiles and standard DDR4 memory speeds up to 3200 MT/s. Actual supported speeds depend on the installed processor and memory configuration.
PCIe Expansion and Dual M.2 Storage
The primary PCIe x16 slot supports PCIe 4.0 with compatible Ryzen 3000 and Ryzen 5000 processors. Supported G-Series processors operate this slot at PCIe 3.0 x16. Additional expansion is provided by a PCIe 3.0 x16-length slot operating at x4 and a PCIe 3.0 x1 slot.
Two M.2 connectors provide options for NVMe and SATA SSDs. The CPU-connected M.2 slot supports PCIe 4.0 x4/x2 with compatible processors, while the chipset-connected M.2 slot supports PCIe 3.0 x2 and SATA SSDs. Four SATA 6Gb/s connectors provide additional storage connections.
Wi-Fi 6 and Bluetooth
The onboard Realtek RTL8851BE wireless module supports Wi-Fi 6 across the 2.4GHz and 5GHz bands, together with Bluetooth 5.3. A Realtek Gigabit Ethernet controller provides wired networking for systems that use a network cable.
Display and Audio Connectivity
Rear display connections include DisplayPort 1.4 and HDMI 2.1. These outputs require a compatible AMD processor with integrated Radeon graphics. Audio is provided by the Realtek ALC1220 codec, with support for multichannel HD audio.
Cooling and RGB Lighting
Smart fan control features provide temperature monitoring and fan-speed management through supported headers. Three addressable RGB Gen2 LED headers and one standard RGB LED header allow connection of compatible lighting components.
