Gigabyte B550M GAMING X WiFi 6 Micro-ATX Motherboard

The Gigabyte B550M GAMING X WiFi 6 delivers reliable performance for AMD Ryzen builds in a compact Micro-ATX form factor. Built on the AMD B550 chipset with AM4 socket support, this motherboard accommodates Ryzen 5000, 4000, and 3000 Series processors, providing a solid foundation for gaming and productivity systems.

Power Delivery and Memory

Equipped with a digital twin 5+3 phases VRM solution and VRM Thermal Armor Advanced cooling, the board ensures stable power delivery to your processor. Four DDR4 DIMM slots support up to 128GB of system memory with speeds up to DDR4-3200 MT/s in dual-channel configuration, with XMP profile support for enthusiast memory kits.

Storage and Expansion

Two M.2 sockets provide flexible NVMe storage options, with the primary M2A_CPU slot supporting PCIe 4.0 x4 on compatible Ryzen processors for maximum transfer speeds. The secondary M2B_SB slot offers PCIe 3.0 x2 connectivity. Four SATA 6Gb/s ports accommodate additional storage drives, with RAID 0, 1, and 10 support across both NVMe and SATA devices.

The PCIe UD Slot design features a reinforced PCIe 4.0 x16 slot with 10X strength for graphics cards, plus an EZ-Latch Quick Release mechanism for tool-free installation and removal. Two additional PCIe slots (x4 and x1) provide room for expansion cards.

Connectivity and Networking

Integrated Realtek WiFi 6 RTL8851BE delivers wireless connectivity with 802.11ax support across 2.4/5 GHz bands, complemented by Bluetooth 5.3. The WIFI EZ-Plug design simplifies antenna installation. Gigabit Ethernet via Realtek GbE LAN chip ensures stable wired networking.

USB connectivity includes four USB 3.2 Gen 1 ports on the rear panel, with additional ports available through internal headers including a USB Type-C header. The fitted I/O shield streamlines installation.

Graphics and Audio

Display outputs include one DisplayPort 1.4 supporting up to 5120x2880@60Hz and one HDMI 2.1 port supporting up to 4096x2160@60Hz, both with HDCP 2.3 and HDR support when using Ryzen processors with integrated graphics. Realtek ALC1220 codec provides high-definition audio with support for up to 7.1-channel configurations and DSD playback through the rear line-out jack.

Features and Software

Q-Flash Plus enables BIOS updates without CPU or memory installation. RGB Fusion 2.0 supports customizable lighting through addressable LED and RGB LED headers. APP Center software suite includes @BIOS, EasyTune, and Smart Backup utilities. The board supports Windows 11 and Windows 10 64-bit operating systems.
