Dual EPYC 9004/9005 1U barebone

The GIGABYTE R183-Z90-AAD2 is a 1U rackmount barebone server designed for dual AMD EPYC 9004 or 9005 series processors in Socket SP5. It targets organisations building general-purpose infrastructure where compute density and memory bandwidth matter. The chassis arrives without CPUs, memory or storage installed.

24 DIMM slots and PCIe Gen5 expansion

This platform replaces older single-socket or PCIe 4.0 systems when workloads demand 12-channel DDR5 RDIMM support across 24 slots and up to 4800 MT/s speeds. The jump is worth it for deployments that need two FHHL PCIe Gen5 x16 slots plus two OCP NIC 3.0 Gen5 x16 slots for modern accelerators or high-speed networking. Dual processor configuration supports cTDP up to 300W per CPU.

SP5 cooling and power budget

Verify that your rack provides adequate airflow for 1U dual-socket thermal design and that your power distribution can sustain the platform at full load. Confirm CPU cooler compatibility with the SP5 socket and 300W cTDP limit. Ensure any SAS drives or controllers match the four hot-swap bays wired from CPU_0.

Questions about this item

What clearance and airflow space does the 1U chassis require in a standard rack?

The 1U form factor occupies a single rack unit; allow front-to-rear airflow and verify cabinet depth for the 4-bay hot-swap backplane and dual FHHL PCIe Gen5 x16 cards.

Which components must be populated before first power-on, and what is the common sequencing error?

Install both EPYC 9004 or 9005 CPUs into the SP5 sockets, then seat RDIMMs across all 12 channels (24 slots total) before adding storage; skipping the full memory population per CPU is the frequent mistake.

Which field-replaceable parts will need attention over the server's life?

Hot-swap SATA/SAS drives in the four 3.5/2.5-inch bays, the three M.2 modules (two PCIe Gen3 x4, one x2), dual FHHL PCIe Gen5 x16 cards, and dual OCP NIC 3.0 cards are all serviceable without removing the chassis.
