GIGABYTE R143-EG2-AAC2 barebone server AMD EPYC 8004 1U 12 DIMM 128GB/s PCIe 5.0 GPU

1U EPYC 8004 barebone for GPU workloads

This 1U rack-mount barebone accepts a single AMD EPYC 8004 series processor in an SP6 socket. It targets cloud providers, edge deployments and SMBs that need PCIe 5.0 GPU acceleration in a compact chassis. The platform delivers 128GB/s I/O bandwidth with CXL 1.1+ support for disaggregated architectures.

PCIe 5.0 GPU slot and twelve DDR5 channels

One full-height full-length PCIe 5.0 x16 slot supports a dual-slot Gen5 GPU for compute acceleration. Six-channel DDR5 RDIMM memory populates up to twelve DIMM slots. Four 2.5-inch bays handle Gen4 NVMe, SATA or SAS drives while eight additional bays accept SATA or SAS media; all bays are hot-swappable. A single M.2 slot provides a PCIe Gen3 x4 interface.

SP6 socket limits upgrades to EPYC 8004 series

The SP6 socket only accepts AMD EPYC 8004 series CPUs, so future upgrades remain within that processor family. Buyers who need a different socket or a dual-processor layout cannot use this chassis. The 1U height also prevents installation of taller expansion cards or additional GPU slots beyond the single x16 connection.
