Micro-ATX server board for AMD Ryzen

The ASRock Rack B550D4U-2T is a micro-ATX motherboard built for single-socket AMD Ryzen processors. It fits 9.6 by 9.6 inch chassis and targets compact servers that need dual 10GbE networking. The board accepts Ryzen 5000, 4000 G-Series and supported 3000 series desktop CPUs in Socket AM4.

Four DDR4 slots with ECC and IPMI

Four 288-pin DDR4 slots run at 3200 and support ECC or non-ECC UDIMM modules. An Aspeed AST2500 controller provides dedicated IPMI management over its own LAN port. Rear I/O includes HDMI, VGA, two USB 3.2 Gen1 Type-A ports, two 10GbE RJ45 ports and a serial header for console access.

Dual 10GbE via Intel X710-AT2

The defining feature is two RJ45 ports driven by an Intel X710-AT2 controller delivering 10Gbps Ethernet. This gives the board high-throughput networking without add-in cards. Builders who need more than two 10GbE links or a different network controller should look elsewhere.

Questions about this item

What practical throughput does the dual 10GbE Intel X710-AT2 controller deliver?

The Intel X710-AT2 provides two RJ45 ports each rated at 10Gbps, giving up to 10 Gbps per link for server or storage traffic.

What chassis clearance and mounting pattern does the 9.6" x 9.6" Micro-ATX board require?

The board fits any Micro-ATX or ATX case with standard 9.6-inch square mounting holes and sufficient height for the I/O shield and full-height expansion cards.

How is the Aspeed AST2500 IPMI configured on first boot, and what step is often missed?

Connect the dedicated IPMI LAN port, set a static IP in the BMC BIOS, then enable KVM-over-IP; forgetting to tag the IPMI VLAN or leaving the default password unchanged are common oversights.
