## Long description

The ASRock WRX90 WS EVO is a workstation motherboard for AMD WRX90 platforms with Socket sTR5, built for high-speed computing and professional workloads. It supports AMD Ryzen Threadripper PRO processors, up to 8 DDR5 RDIMM ECC modules with a maximum capacity of 2 TB, multiple high-speed storage options including PCIe Gen5 M.2, and professional networking with dual 10GbE ports. The board uses a server-grade low-loss, 14-layer 2oz copper PCB and a composite VRM heatsink design to provide stable signals, improved overclocking potential and effective thermal dissipation for reliable, long-lasting operation.
Advantages
The motherboard offers seven PCIe Gen5 x16 expansion slots for maximum throughput to GPUs and add-in cards, support for DDR5 ECC memory for improved data integrity, and PCIe Gen5 M.2 support for up to 128 Gb/s transfer speeds. Server-grade storage connections such as SlimSAS (SFF-8654) and MCIO are included for scalable storage expansions. Additional features include USB4 Type-C with up to 40 Gbps, fast charging via PD 3.0 (up to 9V@3A, 27W), Intel X710-AT2 dual 10GbE LAN, onboard Polychrome RGB headers, Aspeed AST2600 BMC for remote management, and a Multi PSU adaptor option for multi-power-supply configurations.
Suitable for
Professional workstations for 3D rendering and CAD
Deep learning and simulation servers requiring multiple GPUs
High-performance storage and NAS servers using SlimSAS/MCIO
Content creation systems with fast NVMe storage and 10GbE networking

How to use
Install the ASRock WRX90 WS EVO into an EEB-compatible chassis and mount an AMD Ryzen Threadripper PRO processor on the Socket sTR5 according to the processor and chassis manufacturer instructions. Populate memory modules across the eight DDR5 RDIMM ECC slots following the recommended slot population for optimal channel balance. Connect power using the main ATX and auxiliary CPU/board power connectors; add a secondary power supply with the Multi PSU Adaptor Cable if needed. Install GPUs and add-in cards into the PCIe Gen5 x16 slots and attach NVMe SSDs to the PCIe Gen5 M.2 connectors or expand storage via SlimSAS/MCIO. Configure network settings for the Intel X710-AT2 10GbE interfaces and, if remote management is required, enable and configure the Aspeed AST2600 BMC through IPMI.
Usage recommendations
For stable multi-module memory operation and optimal performance, use ECC-registered DDR5 modules listed on ASRock’s memory support list, ensure adequate chassis cooling for the composite VRM heatsink and multiple expansion cards, and use CAT6A or better cabling to achieve full 10GbE throughput.
