HP XW8400 Intel Motherboard Dual Xeon 380688-001 417716-001

HP XW8400 Dual Xeon Workstation Board

This HP XW8400 motherboard is built for dual-socket Xeon workstations using the 771 interface and a 1066 MHz front-side bus. It integrates a Broadcom 5752 Gigabit PCIe network controller and an LSI Logic LSISAS1064 SAS controller alongside SATA 3.0 Gb/s ports with NCQ. The board fits proprietary HP XW8400 chassis and uses part numbers 380688-001 and 417716-001.

Suits multi-threaded legacy workloads not

The eight memory slots and dual-socket design serve render farms, scientific codes or virtualisation hosts that scale across many cores. Builders who need modern instruction sets, high single-core frequency or consumer-grade form factors should look elsewhere. The PCI Express graphics slot runs at x16 while two additional x16 slots are wired x4 electrically, limiting modern GPU bandwidth.

Eight DDR-2 667 ECC slots max 32 GB validated 64

Memory capacity is the decisive spec: the board accepts eight modules at 667 MHz with ECC, validated to 32 GB and enabled for 64 GB. If the target workload demands more than 64 GB or requires faster memory speeds, this platform will not meet the requirement.
