Intel Xeon W workstation board

The GIGABYTE W790 AI TOP is an E-ATX motherboard built for the LGA 4677 socket and Intel Xeon W-3500, W-3400, W-2500 and W-2400 processors. It targets users who train local AI models, run multi-GPU compute or need massive storage bandwidth on a single desktop platform.

DIY install with EZ-Latch aids

PCIe EZ-Latch Plus gives screwless graphics-card removal and WIFI EZ-Plug simplifies the directional antenna. The eight 288-pin DDR5 slots are tightly packed so insert R-DIMMs before mounting the board. Using a W-2500 or W-2400 CPU disables the fourth and fifth x16 slots plus two M.2 connectors; plan the parts list around that constraint.

Verify CPU, memory and case fit

Confirm the chosen Xeon matches the required channel count: W-3500 and W-3400 enable eight-channel DDR5 up to 2 TB, while W-2500 and W-2400 provide four channels. The board needs an E-ATX chassis and a power supply capable of feeding the 16+2+2 phase VRM. Dual 10 GbE LAN, dual Thunderbolt 4 Type-C and Wi-Fi 7 are onboard.

Questions about this item

How can I verify the board is running at the full DDR5 5600 speed after I enable XMP 3.0?

Enter the BIOS, enable the Intel XMP 3.0 profile and confirm the memory frequency reads 5600 MT/s on the main screen or in the HWinfo power monitor.

What ships with the motherboard and what must I source separately for a working build?

The box contains the E-ATX board, I/O shield, Wi-Fi 7 antenna with EZ-Plug base, SATA cables, M.2 screws and documentation; you must add a LGA 4677 Xeon W processor, DDR5 ECC R-DIMMs, storage drives, graphics cards and a PSU.

Which processor choice determines whether all five PCIe 5.0 x16 slots and all six M.2 connectors are active?

A Xeon W-3500 or W-3400 CPU enables all five x16 slots and all six M.2 connectors; a W-2500 or W-2400 CPU disables the fourth and fifth x16 slots and the third and fourth CPU-attached M.2 connectors.
