Product overview

Released in August 2020, Gigabyte’s B550 Gaming X V2 is part of AMD’s 500‑series B550 family for AM4, bringing PCIe 4.0 from the CPU and support for Ryzen 3000/4000G/5000 processors. It continues to receive BIOS updates as recently as April 14, 2026.

Positioned as a mainstream ATX board, it exists to deliver affordable PCIe 4.0 graphics and NVMe plus sensible I/O without extras like onboard Wi‑Fi. Four DDR4 DIMMs (up to 128 GB), one PCIe 4.0 x16 slot for a GPU, dual NVMe M.2 (one up to PCIe 4.0 x4), Realtek 1 GbE, rear HDMI/DVI, and a front‑panel USB‑C header make it a solid base for first‑time builders, expansion/multi‑M.2, overclocking, and high‑speed memory. Unique: HDMI 2.1 output when using a Ryzen APU.
