Socket AM4 server board for Ryzen CPUs

The ASRock Rack X470D4U2-2T is a micro-ATX server motherboard built around the AMD X470 chipset and Socket AM4. It accepts Ryzen 5000, 4000, 3000 and 2000 series desktop processors, including G-Series models with Radeon graphics and PRO variants. Four DDR4 slots support up to 128 GB of ECC or non-ECC UDIMM in dual-channel mode. The board provides dual 10 GbE ports via an Intel X550-AT2 controller plus a dedicated IPMI LAN port for remote management.

Suits dense 1U or 2U builds needing 10 GbE and IPMI

This board fits administrators deploying web hosting or cloud nodes that require two 10 GbE links and out-of-band KVM over a dedicated management port. The splittable PCIe 3.0 x16 slot and a second x8 slot allow GPU, storage or networking add-in cards. Builders who need more than six SATA ports, integrated Wi-Fi, or a larger ATX form factor should look elsewhere.

Dual 10 GbE via Intel X550-AT2 decides fit

The pair of RJ45 10G base-T ports driven by the Intel X550-AT2 is the defining connectivity feature. If the deployment can use dual 10 GbE copper uplinks, this board matches the requirement; if only 1 GbE or fibre uplinks are available, a different platform is appropriate.

Highlights

  • Supports AMD Ryzen 5000, 4000, 3000 and 2000 series CPUs on AM4 socket
  • Dual 10 Gigabit Ethernet ports driven by Intel X550-AT2 controller
  • Up to 128 GB DDR4 ECC UDIMM across four 288-pin slots
  • Six SATA3 6.0 Gb/s ports including one SATA DOM plus two M.2 slots
  • IPMI 2.0 with KVM over dedicated RTL8211E LAN and Aspeed AST2500 video

Questions about this item

Does the board include a CPU cooler or do I need to buy one separately?

The motherboard is sold without a CPU cooler; you must supply a Socket AM4 compatible cooler yourself.

Which memory capacity should I choose if I want the maximum supported?

The board supports up to 128 GB across four DDR4 ECC or non-ECC UDIMM slots in dual-channel mode.

What does the dual 10G LAN spec mean for actual network throughput?

Two Intel X550-AT2 ports provide two 10 Gigabit Ethernet connections over RJ45, each capable of 10 Gb/s line rate.
