GIGABYTE B550M DS3H AC R2 - Motherboard

GIGABYTE B550M DS3H AC R2 - Motherboard arrives as a versatile micro-ATX board built for AMD Socket AM4 systems and modern Ryzen CPUs, offering broad compatibility with the Ryzen 3000, 4000 and 5000 series.

This motherboard is powered by the AMD B550 chipset and supports both DDR4-SDRAM in a 4-slot DIMM configuration and dual-channel memory architecture, giving you up to 128 GB of unbuffered RAM (up to 32 GB per slot) and XMP-like speeds up to 4733 MHz for high-performance multitasking and gaming.

Storage is flexible with two M.2 slots (one with PCIe 4.0 x4 support and the other at PCIe 3.0), four SATA III ports and support for up to six drives overall, as well as RAID 0/1/10 options for performance and redundancy. The board supports both HDDs and SSDs to match a range of storage needs.

Connectivity covers modern essentials with Wi‑Fi 5 (Realtek RTL8821CE) and Bluetooth 5.0 built in, a Gigabit Ethernet port driven by Realtek RTL8111H, multiple USB ports including USB 3.2 Gen 1 Type-A, and legacy PS/2 support. Video outputs include HDMI 2.1 and DisplayPort 1.4 for up to 5120 x 2880 resolution when using a compatible APU or external GPU.

Audio and expansion are well catered for by the Realtek ALC1220-VB codec delivering 7.1 channels, two PCIe x16 slots (one Gen4 x16 and one Gen3 x16), a PCIe x1 slot and five RGB headers for lighting customization. System health monitoring and multiple fan headers help maintain stable temperatures with passive cooling on the board itself.

Practical for builders, the micro ATX form factor (244 x 244 mm) keeps systems compact while providing solid feature density; a CR2032 battery, included antenna, screws and bundled Norton® Internet Security (OEM) make setup straightforward. The motherboard supports Windows 10 x64 and Windows 11 x64 and includes a 3-year warranty for peace of mind.

Use cases include a compact gaming rig with a Ryzen 5000 CPU and a PCIe 4.0 NVMe SSD for fast load times, a content-creation workstation with 128 GB of RAM for multitasking, or an office PC with integrated Wi‑Fi and Gigabit LAN for reliable connectivity. With RAID options, multiple storage bays and robust connectivity, this board fits both enthusiast and professional builds.
