Single-socket SP5 server board

The ASRock Rack TURIND8UD-2T/X550 is a Deep-Micro ATX motherboard built around the SP5 socket for AMD EPYC 9004 and 9005 series processors including 3D V-Cache and 97x4 models. It targets single-processor deployments that need high core density and PCIe 5.0 bandwidth in a compact 10.4 by 10.5 inch footprint.

4 TB DDR5 ceiling and 16 SATA lanes

Eight DDR5 288-pin slots accept registered DIMMs up to 6400 MT/s, scaling to 4 TB total capacity for memory-heavy workloads. Storage connectivity reaches 16 SATA 6 Gb/s ports plus two M.2 slots wired for PCIe 5.0 x4, while four full-length PCIe 5.0 x16 slots also support CXL 2.0 for accelerator or memory-expansion cards.

10 GbE dual-port and flexible power input

Dual RJ45 ports driven by the Intel X550-AT2 controller deliver 2 x 10 Gbps networking without an add-in card. Rear I/O includes D-Sub video and two USB 3.2 Gen 1 Type-A ports; onboard headers add two more USB 3.2 Gen 1 connections. Power delivery uses a 24-pin ATX adapter cable, three 8-pin 12 V connectors and a 6-pin HDD power header for drive arrays.

Questions about this item

Will my existing PCIe 4.0 add-in cards work in the four PCIe 5.0 x16 slots without changing the slot configuration?

Each slot runs at PCIe 5.0 x16 and is backward compatible with PCIe 4.0 cards; install the card and the link will negotiate to the card's maximum speed.

How can I confirm the Intel X550-AT2 10GbE ports are operating at full 10 Gbps after installation?

Check the link speed in the OS network adapter settings or switch port LEDs; both RJ45 ports should show 10 Gbps when connected to a 10 Gbps partner with Cat6a or better cabling.

Does the box include the ATX 24-pin adapter cable for the 4-pin ATX PSU signal connector and the 6-pin HDD power cable?

The 4-pin ATX PSU signal connector ships with an ATX 24-pin adapter cable; the 6-pin HDD power connector is onboard and uses a standard cable from your power supply.
