1U Rack Server with Dual-Slot Gen5 GPU Support
The GIGABYTE R163-SG2-AAC1 is a 1U barebone server designed for compute-intensive workloads. It accommodates a single 5th or 4th Generation Intel Xeon Scalable processor or an Intel Xeon CPU Max Series with HBM. The platform provides 16 DDR5 RDIMM slots across eight channels and includes a PCIe 5.0 x16 slot for a full-height, full-length dual-slot GPU. Ten hot-swap 2.5-inch drive bays and an M.2 slot complete the storage foundation.
Suited for AI Inference and HPC.
This server targets teams deploying GPU-accelerated AI inference, deep learning, or high-performance computing in a dense 1U form factor. It suits builders who need Gen5 NVMe speed and a single high-TDP processor up to 350 W. Buyers requiring dual-processor scaling, more than one double-width accelerator, or 3.5-inch drive carriers should evaluate alternative chassis.
Single LGA 4677 Processor with 350 W TDP Limit
The platform supports exactly one processor in an LGA 4677 socket with a thermal design power ceiling of 350 W. This constraint determines which Xeon Scalable or Xeon CPU Max Series parts can be installed and directly governs the cooling and power infrastructure the build requires.

Questions about this item
Should I pick the 4 x 2.5" Gen5 NVMe/SATA/SAS-4 bays or the 8 x 2.5" SATA/SAS-4 bays for my storage pool?
Use the 4 Gen5 bays for NVMe drives that need PCIe 5.0 bandwidth; the 8 SATA/SAS-4 bays suit high-capacity hard drives or SATA SSDs where Gen5 speed is not required.
What does the 5600 MT/s DDR5 figure mean once the server is built?
With a 5th Gen Xeon and one DIMM per channel the memory runs at 5600 MT/s; populating two DIMMs per channel drops the speed to 4400 MT/s.
How does the OCP 3.0 Gen5 x16 slot limit network card choices?
The slot provides a PCIe 5.0 x16 link to the CPU, so any OCP 3.0 NIC that operates at Gen5 x16 or lower will run at its rated throughput.
