Information

The GIGABYTE B550M DS3H AC R2 is a compact Micro-ATX motherboard built around the AMD B550 chipset, designed to work with AMD Ryzen 3000, 4000, and 5000 Series processors. Finished in a sleek black design, this board fits neatly into smaller builds without compromising on performance or connectivity. It supports up to 128GB of DDR4 memory across four DIMM slots in dual-channel configuration, with memory speeds reaching up to 4733MHz via overclocking. For display output, it features both an HDMI 2.1 port and a DisplayPort 1.4 connection, supporting resolutions up to 5120 x 2880 pixels with HDCP compatibility.

Storage and Expansion
The B550M DS3H AC R2 offers versatile storage options, including two M.2 slots both supporting up to 2280 form factor drives, with one slot running on PCIe 4.0 and the other on PCIe 3.0. Additionally, four SATA III connectors provide ample connectivity for traditional drives. Expansion is further supported by one PCIe 4.0 x16 slot and one PCIe 3.0 x1 slot, giving users flexibility for additional components.

Connectivity and Audio
Wireless connectivity is covered with built-in Wi-Fi supporting standards up to Wi-Fi 5 (802.11ac), complemented by Bluetooth and two antenna jacks for optimal signal performance. Wired networking is handled by the Realtek RTL8111H Gigabit LAN controller. Audio performance is delivered through the Realtek ALC1220-VB chip, enabling 7.1-channel surround sound output. The board also includes a TPM connector, front panel audio header, and USB 3.1 Gen 1 headers for additional connectivity options.
