Performance and expandability
Supports Intel Xeon W-3200 (up to 28 cores / 56 threads, up to 64 PCIe 3.0 lanes in single-socket) and Intel Xeon Scalable processors on LGA3647. Suitable for compute-intensive tasks such as AI training, deep learning, 3D rendering, media production, simulation and visualization.

Multi-GPU and storage
Design allows four double-decked GPUs with full Gen3 x16 bandwidth on supported slots. NVMe expansion via an ASUS NVMe riser card (expandable to up to four NVMe SSDs) and Intel® VROC support (VROC HW key required for NVMe RAID functionality).

Reliability and memory
ECC memory support for single-bit error detection/correction and 12 DIMM slots enabling very large memory capacities (up to 1.5 TB) for stable professional workloads.

Cooling and thermal design
Multiple dedicated heatsinks, metal-fin-array VRM heatsink, interconnected heat-pipe paths and an M.2 heatsink to lower component temperatures and improve longevity.

Management and software
Includes ASUS Control Center (ACC) for centralized IT management: remote BIOS updates, system monitoring and simplified software deployment.
