GIGABYTE R183-Z94-ACV1 barebone server 1U 12-bay 24 DIMM DDR5 6000

Dual-socket EPYC 1U barebone

The R183-Z94-ACV1 is a 1U rackmount server barebone that supports two AMD EPYC 9005 or 9004 series processors in Socket SP5. It targets general-purpose workloads where compute density and memory bandwidth matter. No CPU or memory is installed, so integrators choose exact core counts and capacities. The platform delivers up to 160 PCIe lanes across both sockets.

12 hot-swap bays plus three M.2 slots

Twelve 2.5-inch front bays accept Gen5 NVMe, SATA or SAS-4 drives with hot-swap convenience. Three internal M.2 sockets (2280/22110) provide boot or cache options: two run at PCIe Gen3 x4 from each CPU, the third at Gen3 x2 from CPU 1. Dual OCP NIC 3.0 slots and two full-height PCIe Gen5 x16 slots handle networking and accelerator cards. Dual 1 GbE LAN ports use an Intel I350-AM2 controller. An Aspeed AST2600 manages remote console and IPMI.

Check CPU cTDP and memory population

Each processor can draw up to 300 W cTDP; the OCP NIC 3.0 modules are rated for 400 W cTDP at 30 °C ambient, so cooling and power infrastructure must match. Twenty-four 288-pin DDR5 6000 RDIMM slots operate in 12-channel mode and require registered modules; maximum capacity reaches 9 TB with two DIMMs per channel. Verify that selected EPYC 9005 or 9004 SKUs fit the thermal and power envelope before ordering.
