The board includes M.2 and SATA III interfaces for HDD and SSD storage, supporting RAID levels 0, 1, 5, and 10. It offers multiple Ethernet options including 2.5, 5, and 10 Gigabit Ethernet, making it ideal for high-performance PC builds.

## Long description

The ASRock W790 WS R2.0 is an Extended ATX workstation motherboard for Intel Xeon W and compatible LGA 4677 processors. It supports quad-channel DDR5 RDIMM ECC memory across 8 DIMM slots with up to 2048 GB capacity, multiple PCIe Gen5 x16 slots for high-performance GPUs and add-on cards, and a variety of high-speed storage and network interfaces including PCIe Gen5 M.2, SATA3, mini‑SAS and Aquantia 10Gb/s Ethernet.
Advantages
The board uses a 20+2 power phase Dr.MOS design with Smart Power Stage (SPS) monitoring to provide stable, low-temperature power delivery suitable for overclocking and sustained workloads. A server-grade ultra low loss 14-layer PCB improves signal integrity and energy efficiency, enabling full PCIe 5.0 support for graphics and M.2 devices and increasing memory overclock potential. Reinforced steel PCIe slots and SMT-type PCIe connectors ensure mechanical strength and signal stability at Gen5 speeds. Integrated features such as front USB 3.2 Gen2x2 Type-C, BIOS Flashback and Auto Driver Installer simplify setup and maintenance.
Suitable for
Workstations for professional design, rendering and simulation
Deep learning and compute-heavy applications with multiple GPUs
Enterprise or prosumer servers requiring ECC memory and high capacity (RDIMM ECC up to 2048 GB)
High-speed storage setups using PCIe Gen5 M.2 SSDs and mini‑SAS/SATA arrays

Front I/O: USB 3.2 Gen2x2 Type-C (up to 20 Gbps)
How to use
Install the motherboard into a compatible Extended ATX chassis, secure the LGA 4677 CPU following the processor and socket manufacturer's instructions, and populate memory modules in recommended DIMM slots for quad-channel operation. Connect storage devices to M.2, SATA or mini‑SAS interfaces as needed and insert PCIe Gen5 cards into the reinforced x16 slots. Connect power connectors from a suitable PSU, attach front-panel and rear I/O cables, then power on and enter BIOS to configure memory profiles, boot order and RAID settings if required. Use the BIOS Flashback feature if you need to update BIOS without CPU or memory installed.
Usage recommendations
For stable operation under heavy workloads, use ECC RDIMM modules validated for workstation or server use, ensure adequate cooling for VRM and CPU, and employ high-quality power supplies. When installing multiple high-power GPUs, verify chassis clearance and use the reinforced PCIe slots. Use Cat6 or better cabling to achieve 10Gb/s Ethernet performance and update drivers via the Auto Driver Installer after the first OS boot.
