| Gigabyte WRX90 AI TOP motherboard supports up to 2 TB of ECC DDR5 memory. |
Gigabyte has officially unveiled its WRX90 AI TOP motherboard, a powerhouse platform designed specifically for AI workstations that demand massive memory capacity and multi-GPU configurations. Built for AMD's Ryzen Threadripper PRO processors, this E-ATX board is positioning itself as a serious contender for professionals running demanding local AI workloads.
Unprecedented Memory Support with Active Cooling
At the heart of the WRX90 AI TOP is its extraordinary memory capability. The board features eight DDR5 RDIMM slots operating across eight memory channels, supporting up to a staggering 2TB of ECC memory. What sets this motherboard apart is Gigabyte's innovative DDR Wind Blade XTREME Duo cooling module—a large dual-fan system positioned beside the DIMM slots that drives airflow directly across the memory modules, reducing temperatures by up to 43°C according to Gigabyte's claims.
This active cooling solution addresses a critical challenge in high-density memory configurations, where thermal management becomes essential for maintaining stability during sustained AI workloads.
Seven PCIe 5.0 Slots for Ultimate GPU Scaling
The WRX90 AI TOP doesn't hold back on expansion capabilities. The motherboard sports seven full-length PCIe 5.0 slots connected directly to the processor, with six supporting x16 bandwidth and the seventh operating at x8. Gigabyte demonstrated at Computex 2026 a remarkable configuration running up to nine GPUs, achieved by connecting two additional graphics cards externally through the board's dual MCIO 8i interfaces.
These MCIO connectors also support storage and other PCIe devices, though users should note that some connections share bandwidth. Specifically, one MCIO connector shares bandwidth with the two PCIe 5.0 M.2 slots, meaning those connections cannot all be used simultaneously.
Robust Power Delivery and Comprehensive Cooling
Powering this AI-focused platform is a 32+3+3+3-phase digital VRM design featuring 110A power stages built on a 14-layer server-grade PCB. The board incorporates Gigabyte's VRM Thermal Armor Advanced with extensive heatsinks and a high-conductivity 7 W/mK thermal pad, alongside the SYS Wind Blade system that provides active cooling for both the VRM heatsinks and chipset.
Connectivity and Remote Management
The connectivity suite includes dual server-grade Intel X710 10GbE LAN ports, a dedicated IPMI LAN for remote management traffic separation, two USB4 Type-C ports, and six rear USB 3.2 Gen 2 ports. An ASPEED AST2600 BMC controller enables full IPMI remote management, allowing administrators to monitor hardware, trigger power cycles, and perform system maintenance independently of the operating system.
Storage options comprise two PCIe 5.0 M.2 slots, one PCIe 4.0 M.2 slot, and four SATA ports, providing ample flexibility for high-speed storage solutions.
Software and Compatibility
The WRX90 AI TOP supports Windows 11 and Ubuntu 24.04 LTS, and integrates with Gigabyte's AI TOP Utility for local AI computing. The motherboard is part of the broader GIGABYTE AI TOP ecosystem, designed to provide a foundation for building custom local AI systems.
The board measures 305 × 330 mm in the E-ATX form factor. Gigabyte has not yet announced pricing or a retail availability date for the WRX90 AI TOP.
