Dual-socket EPYC 9004 barebones

The GIGABYTE R183-Z94-AAD1 is a 1U rackmount barebones server built for dual AMD EPYC 9004 or 9005 series processors in Socket SP5. It provides 24 DDR5 4800 RDIMM slots across 12 memory channels per socket and supports CPU cTDP up to 300W, or 400W for the EPYC 9654. No processors or memory are installed.

Suits integrators building dense compute nodes

This platform suits integrators who need 12-channel DDR5 bandwidth, Gen5 PCIe expansion, and 12 front 2.5-inch hot-swap bays that accept NVMe, SATA or SAS-4 drives. It is not for buyers who require GPUs beyond the Aspeed AST2600, single-socket configurations, or installed CPUs and memory. Builders needing 10 Gigabit or faster onboard networking should look elsewhere.

Expansion slots and drive bays define flexibility

Two full-height half-length PCIe Gen5 x16 slots and two OCP NIC 3.0 Gen5 x16 slots allow high-speed accelerators or network cards. Three M.2 slots — two Gen3 x4 and one Gen3 x2 — add boot or cache options. The 12-bay Gen5 backplane and dual 1GbE Intel I350-AM2 ports complete the I/O set.

Questions about this item

Which CPUs and memory must I supply before this barebone will boot?

You need two AMD EPYC 9004 or 9005 series processors for the SP5 sockets and 24 DDR5-4800 registered DIMMs to fill the 12-channel memory subsystem.

Will my existing PCIe Gen4 add-in cards work in the two FHHL Gen5 x16 slots?

Yes, the FHHL PCIe Gen5 x16 slots are backward compatible with Gen4 cards, which will operate at Gen4 speeds.

How can I confirm the 12 front 2.5″ bays are running at Gen5 NVMe speeds after installation?

Check the BIOS or operating-system drive details; each bay should report a PCIe Gen5 x4 link when a Gen5 NVMe drive is seated.
