Silver 1U rack server barebones with four front drive bays

GIGABYTE

GIGABYTE R163-Z34-ACH1 barebone server EPYC 9005/9004 12 DIMM 4 bay Gen5 NVMe/SATA/SAS-4

SKU CH-975A-N5GXC MPN R163-Z34-ACH1

1U barebone server supports single EPYC 9005/9004 CPU, 12 DDR5 DIMM slots, four hot-swap 3.5/2.5 Gen5 NVMe/SATA/SAS bays, dual PCIe Gen5 x16 and dual OCP 3.0 slots

  • Single AMD EPYC 9005/9004 CPU drives high core-count workloads
  • 12-channel DDR5 RDIMM with 12 DIMM slots maximises memory bandwidth
  • Four 3.5"/2.5" hot-swap bays support Gen5 NVMe/SATA/SAS-4 storage
  • Two FHHL PCIe Gen5 x16 slots plus two OCP NIC 3.0 slots expand I/O
  • Dual ROM architecture and Intel I210-AT 1Gb/s LAN enhance platform reliability

EPYC 9005/9004 single-socket barebone

This 1U barebone server accepts one AMD EPYC 9005 or 9004 series processor and provides twelve DDR5 RDIMM slots across twelve memory channels. It targets deployments that need high core density and local storage in a single rack unit.

Twelve DIMM slots and four hot-swap bays

Memory installs vertically into twelve keyed DDR5 RDIMM sockets; the board uses a dual ROM design for firmware redundancy. Four 3.5"/2.5" bays support Gen5 NVMe, SATA and SAS-4 drives with tool-less carriers, while the M.2 slot uses a PCIe Gen3 x4 link.

Twelve-channel memory and dual PCIe Gen5 x16 slots

The twelve-channel architecture feeds memory bandwidth to all cores, and two full-height half-length PCIe Gen5 x16 slots plus two OCP NIC 3.0 Gen5 x16 slots provide expansion for accelerators or networking. Storage headroom ends at four front bays and one M.2 device.

Questions about this item

How do I verify the EPYC 9005 processor is recognised across all 12 DDR5 channels after first boot?

Enter the BIOS and confirm that all 12 DIMM slots show populated and running at the expected DDR5 speed; the dual ROM architecture will also post a checksum pass if the CPU initialisation succeeds.

Which drive types fit the four front bays without extra caddies or adapters?

The 3.5" and 2.5" hot-swap bays accept Gen5 NVMe, SATA and SAS-4 drives directly; the M.2 slot takes a PCIe Gen3 x4 module and the two FHHL plus two OCP NIC 3.0 slots are for add-in cards only.

Which EPYC series should I choose if I need maximum core count versus maximum clock speed?

The 9005 series delivers higher core counts for dense virtualisation, while the 9004 series offers higher base frequencies for single-threaded workloads; both fit the single-socket design and 12-channel memory controller.
