GIGABYTE R263-S33-AAF1 barebone server 12 bays 16 DIMMs 3 GPUs

High-density GPU server barebone

The GIGABYTE R263-S33-AAF1 is a 2U rackmount barebone built for workloads that demand heavy GPU acceleration and local storage density. It accepts a single LGA 4677 processor from the 4th or 5th Gen Intel Xeon Scalable families, including the Xeon CPU Max Series. The chassis delivers twelve hot-swap 3.5 or 2.5 inch SATA/SAS bays and room for three dual-slot Gen5 GPU cards. A 2400W redundant power supply and dual ROM architecture complete the platform.

Suited for AI training and visual computing

This server targets teams running AI training, AI inference, visual computing or other high-performance computing tasks that benefit from up to three modern GPUs and twelve drive bays in a 2U form factor. The single-socket design and sixteen DDR5 DIMM slots support up to 2TB of ECC memory for large datasets. Organisations needing dual-processor scaling, more than three GPU slots, or connectivity beyond the single 1GbE LAN port should consider other chassis designs.

Sixteen DDR5 DIMM slots define memory capacity

The board provides sixteen RDIMM slots across eight channels, enabling a maximum of 2TB of DDR5 ECC memory with a single processor. Population rules and supported speeds follow the chosen Xeon Scalable CPU, so the final memory ceiling is set by the processor SKU rather than the barebone alone. Verify the specific CPU memory specifications before ordering DIMMs.
