Asrock WRX90 WS EVO

ASRock WRX90 WS EVO – Professional WRX90 / sTR5 workstation motherboard for Threadripper PRO platforms

The ASRock WRX90 WS EVO is a high-performance workstation motherboard designed around the AMD WRX90 chipset and the sTR5 socket. It supports AMD Ryzen Threadripper PRO 7000 and 9000 WX-Series processors up to 96 cores, offering enterprise-class reliability, extensive PCIe 5.0 expansion, ECC RDIMM memory support, flexible storage connectivity and dual 10 GbE networking. This platform is engineered for heavy compute workloads such as multi-GPU rendering, AI and ML training, scientific simulation, virtualisation and professional workstation-server hybrid builds.

CPU and memory architecture

• Socket: sTR5; Chipset: AMD WRX90
• Supports Threadripper PRO 7000 WX and 9000 WX CPUs
• Up to 96 cores depending on processor model
• Eight DDR5 RDIMM / RDIMM-3DS slots
• ECC-only memory configuration with up to 2 TB capacity
• Eight-channel memory architecture with high bandwidth and stability

The memory subsystem delivers the throughput required for large datasets, simulations, multi-application workflows and virtualisation environments, ensuring stability and integrity under continuous operation.

Power delivery and reliability

The WRX90 WS EVO features an 18+3+3 phase VRM built with 110A Smart Power Stages and premium server-grade components. A 14-layer PCB with 2 oz copper internal layers improves power stability and signal integrity. These elements provide sustained performance under heavy CPU loads, making the board suitable for long-duration rendering, compute-intensive analysis and enterprise applications.

PCIe 5.0 expansion and multi-GPU support

• Seven PCIe 5.0 x16 slots
• Six slots support full x16 bandwidth, one x8 depending on layout
• Designed for multi-GPU configurations, accelerators and high-speed I/O

This configuration enables sophisticated compute systems including multi-GPU render stations, AI/ML training nodes, simulation environments or hybrid workstations requiring both GPU acceleration and additional PCIe-based storage or networking expansion.

Storage capabilities

• 1 × M.2 PCIe 5.0 x4 slot (2280/22110)
• 1 × M.2 PCIe 4.0 x4 slot (2280/22110)
• 2 × MCIO connectors (configurable as PCIe 5.0 or SATA)
• 2 × SlimSAS SFF-8654 connectors (PCIe 4.0 x4 or SATA)
• 4 × SATA 6 Gb/s ports
• RAID support for performance or redundancy

The flexible storage architecture supports high-speed NVMe arrays, hybrid NVMe/SATA layouts, multi-drive backplanes and enterprise drives, making the platform suitable for large datasets, media workflows, virtualisation storage or scratch disks for compute applications.

Networking and connectivity

• Dual 10 GbE LAN (Intel X710-AT2)
• Dedicated IPMI LAN port for remote management
• Two USB4 Type-C ports on rear I/O
• Multiple USB 3.2 Gen2 / Gen1 Type-A ports
• Internal headers for USB-C, USB-A and USB2.0 front-panel connectivity
• Realtek ALC1220 audio subsystem

With integrated dual 10 GbE, the board is ready for high-bandwidth environments such as render farms, shared storage systems or distributed compute clusters. IPMI remote management enables full out-of-band control, which is essential for professional deployments and headless workstation-server setups.
