GIGABYTE B550M K (AM4) DDR4 Micro-ATX Motherboard

Description

Overview

The GIGABYTE B550M K is a compact Micro-ATX motherboard for AMD Socket AM4 processors. It brings the B550 chipset’s PCIe 4.0 support to a small form factor, making it a practical choice for budget-conscious gaming, productivity or home-office systems that still want current-generation connectivity.

Key features

• Support for AMD Ryzen 5000/4000 G-Series and 3000 Series processors (see Gigabyte CPU Support List for exact CPU/Bios requirements).
• Four DDR4 DIMM slots supporting up to 128 GB (supports XMP and a variety of DDR4 speeds up to listed overclocked frequencies).
• PCIe 4.0 x16 slot for discrete graphics when used with compatible Ryzen CPUs, plus one PCIe x1 slot.
• Dual M.2 sockets: one M.2 wired to the CPU (PCIe 4.0 x4 with compatible CPUs) and a second M.2 from the chipset (PCIe 3.0 x2), plus four SATA 6Gb/s ports.
• Rear HDMI and DisplayPort outputs for APUs with integrated Radeon graphics, Realtek 1GbE LAN and a Realtek HD audio codec.

Because Gigabyte produces multiple board revisions (for example Rev. 1.0 and Rev. 1.1) confirm the exact revision and BIOS version when pairing with newer Ryzen CPUs. Check the official Gigabyte product page and the CPU support list for the latest compatibility and BIOS downloads.
