The GIGABYTE B550M GAMING X is a Micro ATX motherboard built around the AMD B550 chipset for desktop PCs. Its AM4 socket supports AMD Ryzen 3000, 4000, and 5000 Series processors. Four DDR4 DIMM slots accommodate up to 128 GB of unbuffered memory in a dual-channel configuration, with supported memory speeds of up to 3200 MHz. Storage connections include four SATA III ports and two M.2 slots, supporting both PCIe 4.0 and PCIe 3.0 devices.
Expansion is provided by two physical PCIe x16 slots — one running at PCIe 4.0 x16 and the other at PCIe 3.0 x4 — plus a PCIe 3.0 x1 slot for an additional expansion card. A single Gigabit Ethernet port handles wired networking; Wi-Fi is not built in. The rear panel offers HDMI 2.1 and DisplayPort 1.4 outputs for processors with integrated graphics, though actual availability depends on the installed CPU. Power is delivered via a 24-pin ATX connector and an 8-pin CPU connector.
Key Features:- Four rear USB 3.2 Gen 1 Type-A ports and two USB 2.0 ports for peripheral connections.
- Two internal USB 3.2 Gen 1 headers and one USB 2.0 header for front-panel USB.
- RAID 0, 1, and 10 support for storage array configuration.
- Realtek ALC1220 audio codec with a front-panel audio header for onboard audio.
- One CPU-fan header and two chassis-fan headers for system cooling.
- An RGB LED header for connected lighting hardware.
- A TPM connector for an optional TPM module.
