Dual-Socket EPYC Barebones Server

The GIGABYTE R283-Z97-AAL1 is a 2U rackmount barebones chassis designed for dual AMD EPYC 9004 and 9005 series processors. It targets AI, machine learning and high-performance computing workloads that demand high core counts and memory bandwidth. The platform supports up to two CPUs with cTDP up to 240W each.

Fits GPU-Accelerated HPC Builds

Suits integrators building dense GPU clusters with 12+4 hot-swap drive bays and dual PCIe Gen5 x16 GPU slots. Not for buyers who need installed CPUs, memory or storage. Builders requiring single-socket density or lower power envelopes should evaluate other platforms.

24-Channel DDR5 Memory Architecture

Twelve memory channels per socket feed 24 DIMM slots for DDR5 4800 registered modules. This capacity and bandwidth profile determines whether the system meets the dataset size and throughput requirements of the target workload.

Questions about this item

How much power does the 2700 W titanium supply draw when the dual EPYC 9005 CPUs and 24 DDR5 4800 DIMMs run continuously?

The 2700 W titanium PSU delivers up to 2700 W; each EPYC 9005/9004 CPU has a cTDP up to 240 W and the 24 DDR5 4800 slots add further load, so sustained draw depends on the exact processors and memory population you install.

Which components are not included and must be supplied before the R283-Z97-AAL1 will POST?

The barebones ships with no CPU and no memory; you must provide two AMD EPYC 9005 or 9004 series processors for the SP5 sockets and up to 24 DDR5 4800 registered DIMMs across the 12 channels.

Can I keep my existing 3.5-inch SAS-4 drives and 1 GbE network cabling when moving to this 2U chassis?

Yes — the front provides eight 3.5"/2.5" bays and four additional 3.5"/2.5" bays that accept SAS-4 and SATA drives, while the dual Intel I350-AM2 ports maintain 1 GbE connectivity over standard copper.
