Socket sTR5 workstation board

The ASRock WRX90 WS EVO is a server motherboard built around the AMD WRX90 chipset for Socket sTR5 processors. It accepts AMD Ryzen Threadripper PRO 9000 and 7000 WX-Series CPUs and provides eight DDR5 DIMM slots with eight-channel architecture. Registered ECC memory up to 2 TB is supported.

For multi-GPU compute, not compact builds

This board suits users who need seven PCIe 5.0 x16 slots for accelerators, dual 10 GbE networking and extensive NVMe or SAS storage. Builders requiring a smaller form factor, consumer-grade audio or integrated Wi-Fi should look elsewhere.

Eight-channel DDR5 Registered ECC

The defining specification is the eight-channel DDR5 controller with support for Registered ECC modules up to 7600 MT/s OC. If your workload demands maximum memory bandwidth and capacity with error correction, this platform delivers; otherwise a dual-channel desktop board will suffice.

Highlights

  • Supports AMD Ryzen Threadripper PRO 9000/7000 WX-Series processors
  • 18+3+3 power phase design with 110A SPS for VCore
  • Eight-channel DDR5 ECC registered memory up to 7600 MT/s and 2 TB capacity
  • Seven PCIe 5.0 x16 slots with 15 µm gold contacts
  • Dual Intel 10 Gigabit LAN plus dedicated IPMI management port

Questions about this item

How do I decide between the seven PCIe 5.0 x16 slots when one runs at x8?

Use the six full x16 slots for GPUs or high-bandwidth add-in cards; the x8 slot still provides Gen5 bandwidth for NVMe adapters or secondary devices.

What does the DDR5 7600 (OC) rating mean once modules are installed?

The board supports eight-channel DDR5 ECC Registered memory up to 2 TB; 7600 MT/s is the validated overclock ceiling, actual speed depends on the CPU and DIMM combination.

What real throughput does the dual 10 Gigabit LAN deliver?

The Intel X710-AT2 controller provides two RJ-45 ports at 100/1000/2500/5000/10000 Mb/s with PXE support for network boot.
