Intel LGA 4677 Platform & Xeon W Compatibility

At its core, the Pro WS W790-ACE features the Intel LGA 4677 socket, fully optimized for Intel Xeon W‑3400 and W‑2400 workstation processors. These CPUs deliver exceptional multi‑threaded performance, advanced security features, and enterprise‑class reliability for professional applications. The motherboard supports CPU and memory overclocking to push performance beyond stock limits, ideal for users who need maximum throughput for intensive tasks. Combined with the Intel W790 chipset, the platform provides high bandwidth, low latency, and extensive I/O capabilities to support professional workflows without bottlenecks.

High‑Capacity DDR5 ECC Memory Architecture

Memory performance and stability are critical in workstations, and the Pro WS W790-ACE delivers with 8×DIMM slots supporting 4‑channel DDR5 ECC R‑DIMM memory at 2 DIMMs per channel (2DPC). It supports up to 2TB of ECC memory, which automatically detects and corrects data corruption in real time, drastically reducing system crashes and data errors in long‑duration workloads. ASUS has optimized the memory trace layout for signal integrity and overclocking headroom, allowing users to run DDR5 at higher frequencies while maintaining rock‑solid stability. Whether you are working with massive datasets, high‑resolution media assets, or virtual machines, this memory subsystem ensures fast access and smooth multitasking.

Robust 12+1+1 Power Stage Design

Stable power delivery is essential for Xeon processors and multi‑GPU configurations. The Pro WS W790-ACE uses a 12+1+1 phase VRM design with high‑quality power stages to provide clean, efficient power under full load. An additional 8‑pin PCIe power connector improves stability when using multiple high‑power graphics cards, preventing voltage drops and system instability during intense rendering or simulation. Massive VRM heatsinks with dense fins and high surface area keep power components cool, maintaining consistent performance even during extended 100% load scenarios. This power solution ensures the motherboard can sustain maximum performance for hours without throttling.

Ultra‑Fast Connectivity: PCIe 5.0, Networking, USB & Storage

PCIe 5.0 Expansion

The board comes with 5×PCIe 5.0 x16 SafeSlot slots, reinforced with ASUS SafeSlot technology for enhanced strength and shear resistance. These slots support multiple high‑performance GPUs for parallel computing, 3D rendering, AI acceleration, and video production. PCIe 5.0 doubles the bandwidth of PCIe 4.0, ensuring future‑proofing for next‑generation workstation graphics cards, RAID cards, and accelerator cards.

High‑Speed Networking

For fast data transfer and network integration, the Pro WS W790-ACE includes dual high‑speed Ethernet ports:
– 1×Marvell AQC113CS 10G LAN for NAS, high‑speed file sharing, and server connectivity
– 1×Intel I226‑LM 2.5G LAN for daily networking, streaming, and uploads
This dual LAN configuration improves workflow efficiency by separating high‑speed storage traffic from general network usage.

USB 3.2 Gen 2×2 Type‑C

The motherboard features front and rear USB 3.2 Gen 2×2 Type‑C ports delivering up to 20Gbps bandwidth—twice the speed of standard USB 3.2 Gen 2. These ports offer fast transfers for external SSDs, high‑resolution cameras, and portable work devices, with reversible connectivity for convenience.

Flexible Storage Options

Storage flexibility meets high performance:
– 2×M.2 slots (22110 + 2280) supporting PCIe 4.0 x4 NVMe SSDs with dedicated heatsinks to prevent thermal throttling
– 3×SlimSAS ports for enterprise SSDs and server‑grade storage via PCIe 4.0/3.0
