Our take on the ASRock W790 WS Gaming Motherboard

The ASRock W790 WS is a workstation motherboard for Intel's 4th Gen Xeon W-3400 and W-2400 processors on LGA 4677. It stands out with four PCIe 5.0 x16 slots, four PCIe 5.0 M.2 sockets, eight DDR5 ECC registered slots up to 2 TB, and dual 10 GbE plus 2.5 GbE networking. That puts it against workstation boards like the ASUS Pro WS W790-ACE and Gigabyte MW34-SP0, with more PCIe 5.0 lanes and M.2 than most rivals. It suits workstation builders running CAD, simulation, rendering or local AI work who need memory capacity and fast storage more than gaming features.

Pros
  • Four PCIe 5.0 x16 slots for multi-GPU and add-in cards
  • Four PCIe 5.0 x4 M.2 sockets plus a U.2 port and eight SATA
  • Eight DDR5 ECC registered slots, up to 2 TB
  • Dual 10 GbE and 2.5 GbE LAN built in
  • Two USB4 Thunderbolt 4 Type-C ports
  • 20+2 phase, 90A power design on a 14-layer PCB
Cons
  • LGA 4677 limits you to Xeon W-2400 and W-3400 chips
  • Extended ATX size needs a large case
  • Workstation platform costs far more than mainstream desktop boards
  • No DDR4 option; registered ECC DDR5 is required for full capacity
  • Overclocking headroom is modest compared with consumer boards

Questions and answers

Which CPUs does the ASRock W790 WS support?
It supports 4th Gen Intel Xeon W-3400 and W-2400 processors on the LGA 4677 socket. Consumer Core chips do not fit.
How much memory can it take?
Eight DDR5 slots support up to 2 TB of registered ECC memory in quad channel. Overclocked speeds reach around 6800 MT/s.
Does it support multiple GPUs?
Yes. Four PCIe 5.0 x16 slots allow multi-GPU setups, though lane sharing depends on how many cards you install.
Is Thunderbolt included?
Yes, two USB4 Thunderbolt 4 Type-C ports are on the rear I/O. You still need a compatible Thunderbolt device and cable.
What case fits this board?
It is Extended ATX, so you need a full-tower or workstation case that lists E-ATX support. Check clearance for the 10 GbE ports and large coolers.
Is it good for gaming?
It works for gaming, but Xeon W chips favor multi-core workstation work over high frame rates. A mainstream Z790 board is a better fit for pure gaming.
