2U Dual-Socket EPYC Barebone

The GIGABYTE R283-Z97-AAF1 is a 2U rackmount server barebone designed for AI, ML and HPC workloads. It accepts up to two AMD EPYC 9004 or 9005 series processors in SP5 sockets with a cTDP up to 240W. The platform provides 24 DDR5-4800 RDIMM slots across 12 memory channels per CPU. No processors or memory are installed.

Verify CPU, Memory and Drive Compatibility

Confirm that your chosen EPYC 9004 or 9005 CPUs match the SP5 socket and 240W cTDP limit. Source 288-pin DDR5-4800 registered DIMMs to populate up to 24 slots. The front bays accept 3.5-inch or 2.5-inch Gen5 NVMe, SATA or SAS-4 drives, while rear bays take 2.5-inch SATA or SAS-4 units. Two M.2 slots per CPU are occupied for SATA use.

Dual-Slot GPU Support and OCP Networking

The chassis includes two full-height full-length PCIe Gen5 x16 slots rated for dual-slot Gen5 GPUs, plus two full-height half-length Gen5 x16 slots and two OCP NIC 3.0 Gen5 x16 slots. An Aspeed AST2600 provides baseboard management graphics. Dual 1GbE LAN ports via Intel I350-AM2 handle standard network traffic.

Questions about this item

Does the barebone include any CPUs, memory modules or drives, or must I supply them all?

The unit ships with no EPYC processors, no DDR5 RDIMMs and no storage installed; you must add up to two Socket SP5 CPUs, 24 DDR5 4800 modules and your choice of drives.

Which EPYC 9004-series processor should I choose for this 2U chassis?

Any Socket SP5 AMD EPYC 9004 or 9005 CPU up to 240 W cTDP is supported; pick core count and clock to match your AI, HPC or general compute workload.

What does the 12-channel DDR5 4800 specification mean for real-world memory bandwidth?

Each socket provides twelve DDR5 4800 channels, so a dual-CPU configuration delivers 24 channels of registered ECC memory for maximum throughput in memory-intensive tasks.
