ASRock Rack
EEB server motherboard for single AMD EPYC 9004 or 9005 CPUs up to 500W TDP, eight DDR5 DIMM slots, seven PCIe 5.0 x16 slots plus one x8, and two M.2 sockets
The ASRock Rack TURIND8X-2T/500W is an EEB form-factor server motherboard measuring 12.63 by 13 inches. It uses the SP5 socket (LGA 6096) and accepts AMD EPYC 9004 and 9005 series processors with TDPs up to 500 watts. Eight DDR5 RDIMM slots operate in a 1DPC layout and support RDIMM-3DS modules for a maximum of 128GB of memory.
Seven full-length PCIe 5.0 x16 slots are provided, four of which also carry CXL 2.0 signalling, alongside one PCIe 5.0 x8 slot. Two M-key M.2 sockets accept 2280 or 22110 modules; one runs at PCIe 5.0 x4 or four SATA 6Gb/s lanes, the other at PCIe 5.0 x4 only. This density suits GPU-heavy or accelerator-heavy builds but leaves no room for legacy PCIe 3.0 or 4.0-only add-in cards.
The 500-watt TDP ceiling demands a cooler rated for that thermal load and a chassis with sufficient airflow depth for the EEB footprint. Confirm that your power distribution can deliver the required EPS connectors and that the backplane or drive cage wiring matches the six MCIO ports offering up to sixteen SATA 6Gb/s connections.

The board accepts DDR5 RDIMM and RDIMM-3DS modules in a 1 DIMM per channel layout across 8 slots, with a total capacity limit of 128GB.
Yes, the seven PCIe 5.0 slots — six x16 and one x8 — are backward compatible with PCIe 4.0 cards, which will operate at their native 4.0 speeds.
Check the BIOS or operating system device manager to verify the M.2 slot reports a PCIe 5.0 x4 link width for the installed drive.
