GIGABYTE W790 AI TOP E-ATX Motherboard (LGA4677)

Description

Overview

The GIGABYTE W790 AI TOP is an E‑ATX workstation motherboard built around the Intel W790 chipset and LGA4677 socket. It is designed for Intel Xeon W‑series processors and for systems that require high memory capacity, multiple PCIe 5.0 expansion lanes and fast networking for data‑intensive workloads.

Key features

• Socket LGA4677 — supports Intel® Xeon® W‑3500 / W‑3400 / W‑2500 / W‑2400 series processors (refer to CPU support list for exact models).
• Memory: 8× DDR5 DIMM slots with support for RDIMM (ECC) up to 2 TB total; 5600(O.C.) / 4800 MHz support and XMP compatibility.
• Expansion: up to five PCIe x16 slots (PCIe 5.0 via CPU), with multiple slots and M.2 connectors becoming unavailable depending on CPU family.
• Storage: 4× CPU‑direct M.2 (PCIe 5.0 x4, 2280) + 2× chipset M.2 (PCIe 4.0 x4) and 8× SATA 6Gb/s; RAID 0/1/5/10 for SATA and NVMe.
• Connectivity: Dual Intel® X710‑AT2 10GbE, Intel® Wi‑Fi 7 (BE200NGW) with Bluetooth 5.4, and 2× USB4 / Thunderbolt™ 4 Type‑C on the rear I/O.
• Rear I/O includes DP In ports, multiple USB 3.2/3.1 ports and optical S/PDIF; Realtek HD audio (up to 7.1). 30.5 × 33.0 cm E‑ATX form factor.

Because certain CPU families (W‑2500/W‑2400 series) change available memory channels, PCIe and M.2 assignments, verify the exact CPU model when planning builds to ensure required slots and memory channels remain available.
