Dual AMD EPYC 9005/9004 barebone server

The GIGABYTE R283-Z96-AAJ1 is a 2U rackmount barebone designed for dual AMD EPYC 9005 and 9004 series processors. It provides 24 DDR5 RDIMM slots across twelve memory channels per socket. The chassis integrates 24 front-access 2.5-inch Gen5 NVMe hot-swap bays and four rear 2.5-inch SATA/SAS-4 hot-swap bays. No CPU or memory is installed.

Suited for high-density NVMe storage workloads

This platform suits builders who need maximum Gen5 NVMe density in a 2U form factor with dual-socket compute. It is not for buyers who require more than two processors, or who need a single-socket configuration. It also does not suit teams lacking infrastructure for 2U rackmount deployment and high-wattage cooling.

24 front Gen5 NVMe hot-swap bays

The defining specification is the 24 front 2.5-inch bays wired for PCIe Gen5 NVMe drives. This bay count and interface combination determines whether the chassis matches the storage throughput and capacity targets of the deployment.

Questions about this item

Will my existing DDR5-4800 RDIMMs work in the 24 slots of this R283-Z96-AAJ1?

Yes — the board accepts 24 DDR5-4800 registered DIMMs across 12 channels, so your current modules will install and run at their rated speed.

How can I verify both EPYC processors are recognised after I populate the dual SP5 sockets?

The Aspeed AST2600 BMC provides a web UI and IPMI-over-LAN; log in and check the FRU/SEL pages — each socket will show its own CPU model, core count and temperature sensors.

Which drives and accessories are included with the barebones chassis?

The unit ships with the 2U chassis, motherboard, dual-SP5 backplane, 24 front NVMe bays, 4 rear SATA/SAS-4 bays, two M.2 slots, one FHHL PCIe Gen5 x16 slot and one OCP NIC 3.0 slot — CPUs, memory, storage drives and rails are not included.
