ATX Server Motherboard for Threadripper PRO

The ASRock Rack WRX80D8-2T is an ATX form-factor server motherboard built around the AMD WRX80 chipset. It accepts a single AMD Ryzen Threadripper PRO processor in the sWRX8 socket, covering both the 5000WX and 3000WX series. Eight DDR4 DIMM slots provide eight-channel memory architecture with support for ECC and registered modules.

Workstations needing seven full-length PCIe 4.0

This board suits builders who require seven PCIe 4.0 x16 expansion slots driven directly by the CPU, plus two OCuLink connectors that can operate as PCIe 4.0 x4 or four SATA 6Gb/s ports. Dual 10GbE RJ45 ports from an Intel X710-AT2 controller and an Aspeed AST2500 video chipset complete the feature set. Buyers who need more than one processor socket or a different CPU family should look at alternative platforms.

Maximum memory capacity depends on module type

ECC and non-ECC UDIMM, RDIMM and LRDIMM configurations are validated up to 128GB, while RDIMM-3DS modules can reach 256GB pending validation. Memory speed is DDR4 3200 across all supported types. Selecting the correct module format determines the total capacity the system can address.

Highlights

  • Supports AMD Ryzen Threadripper PRO 5000WX and 3000WX series processors
  • Eight DDR4 3200 channels with ECC up to 256 GB RDIMM-3DS capacity
  • Seven PCIe 4.0 x16 slots for high-bandwidth expansion cards
  • Dual 10 GbE Intel X710-AT2 ports for fast network throughput
  • Twelve SATA 6 Gb/s plus two M.2 PCIe 4.0 x4 and two OCuLink connectors

Questions about this item

How do I install the Threadripper PRO CPU into the sWRX8 socket without bending pins?

Align the gold triangle on the processor with the socket corner marker, lower it vertically without pressure, close the retention frame and torque the captive screws in a cross pattern to the specified value.

Which DIMM modules from the QVL should I use if I later need to replace a failed stick?

The qualified list includes Micron 64 GB RDIMM MTA36ASF8G72PZ-3G2B2VI, Samsung 64 GB RDIMM M393A8G40AB2-CWEGY and SMART 128 GB RDIMM ST1637RD440465-SM at DDR4 3200.

At what point does the Aspeed AST2500 video output become the bottleneck during sustained headless operation?

The AST2500 provides basic 2D console graphics only; it does not accelerate compute workloads, so the limit appears immediately when any GPU-accelerated task is redirected to it.
