Gigabyte B850M DS3H ICE AM5 Micro‑ATX DDR5 Motherboard
GA-B850M-DS3H-ICE
The Gigabyte B850M DS3H ICE is a high-performance, white-themed Micro‑ATX motherboard built around the AMD B850 chipset and Socket AM5, compatible with Ryzen 9000 / 8000 / 7000 series processors. Engineered for both gamers and creators, it features a refined 8+2+2 digital VRM design, support for DDR5 memory up to 8200 MT/s, and two ultra-fast M.2 SSD slots (one PCIe 5.0 x4). Additional robustness comes via M.2 Thermal Guard, EZ-Latch ROI support, Smart Fan 6 cooling, dual DisplayPort + HDMI outputs, and 2.5GbE LAN connectivity. Plus, X3D Turbo Mode (BIOS-based) improves gaming performance for all Ryzen CPUs without needing a premium X3D model.
