The Gigabyte B550M DS3H AC R2 is a feature-rich micro-ATX motherboard designed for AMD Ryzen 3000, 4000, and 5000 series processors. Built on the AM4 socket with the B550 chipset, this board delivers PCIe 4.0 performance for next-generation storage and graphics expansion while maintaining excellent value for budget-conscious builders.
This motherboard supports up to 128GB of DDR4 memory across four DIMM slots, with support for speeds up to DDR4-4733MHz. The board features 2x M.2 NVMe slots (one PCIe 4.0 x4, one PCIe 3.0 x4) for fast SSD storage, plus 4x SATA 6Gb/s ports for traditional drives. Connectivity includes HDMI 2.1 (supporting 48Gb/s bandwidth and 21:9 cinematic ratio) and DisplayPort for video output, Gigabit Ethernet LAN, and Wi-Fi 5 AC with antenna for wireless connectivity. The board includes 3x RGB LED headers and 2x ARGB headers for customizable lighting, plus Smart Fan 6 technology with dual fan curve modes (Slope and Stair) for precise thermal management.
Additional features include a 5+3 phase digital VRM with thermal armor, 4x USB 3.0 ports and 2x USB 2.0 ports on the rear I/O, 3x PWM/DC fan headers supporting up to 24W per header, and support for AMD StoreMI technology for optimized storage performance. The compact micro-ATX form factor (244mm x 244mm) makes it ideal for smaller builds while maintaining excellent expansion options.
