Product overview

Released in September 2020 as part of GIGABYTE’s AMD B550 AM4 lineup, the B550M DS3H AC targets Ryzen 3000/4000G/5000 systems and brings PCIe 4.0 to a compact micro‑ATX board with built‑in 802.11ac Wi‑Fi. It’s a mainstream B‑series option that exists to deliver essential B550 features—PCIe 4.0 x16 and dual M.2 (one PCIe 4.0, one PCIe 3.0/SATA)—at low cost. It’s well‑suited to everyday Ryzen builds needing two NVMe drives, four DDR4 slots (up to 128 GB, ECC/Non‑ECC UDIMM), Realtek GbE, and APU video outs (HDMI + DVI) in a mid‑tower or compact case. Notable convenience: Q‑Flash Plus enables BIOS updates without a CPU, RAM, or GPU installed.
