GIGABYTE G493-ZB3-AAP1 barebone server 12-channel DDR5 48 DIMMs 12 NVMe bays

SKU CH-5XFB-604NV MPN G493-ZB3-AAP1

Barebone server with dual AMD EPYC 9004 processors, 12-channel DDR5 across 48 DIMM slots and 12 hot-swap 2.5-inch NVMe bays for GPU-dense workloads

  • Supports eight dual-slot Gen5 GPUs for dense AI compute
  • Dual AMD EPYC 9004 processors with 3D V-Cache technology
  • 12-channel DDR5 memory across 48 DIMM slots
  • 12 hot-swappable 2.5-inch NVMe, SATA, SAS-4 drive bays
  • NVIDIA-Certified System for validated data-centre deployment

Built for dense GPU compute

The GIGABYTE G493-ZB3-AAP1 is a 4U dual-processor barebones server designed for high-performance computing and AI workloads. It supports two AMD EPYC 9004 series CPUs with 3D V-Cache technology and accommodates up to eight dual-slot PCIe Gen5 GPUs via integrated PCIe switches.

Twelve hot-swap bays and dual ROM

Twelve 2.5-inch front bays accept Gen5 NVMe, SATA or SAS-4 drives for fast, flexible storage. Two M.2 slots provide additional PCIe Gen3 x4 capacity. Dual ROM architecture adds firmware redundancy, while dual 1GbE LAN ports via Intel I350-AM2 handle basic management traffic.

Suits clusters needing maximum GPU density

This platform fits teams building training or inference clusters that require eight Gen5 GPUs in a single chassis with 48 DDR5 DIMM slots. Buyers who need more than twelve front drives, higher-speed networking or single-socket economics should evaluate alternative configurations.

Questions about this item

How are the 48 DDR5 DIMM slots serviced if a module fails?

The 48 DDR5 RDIMM slots are accessible inside the 4U chassis for module replacement when a DIMM fails.

Which component reaches its thermal limit first when all 12 NVMe bays run sustained writes?

The 12 Gen5 NVMe drives in the hot-swap bays typically hit thermal throttling before the CPUs or memory under sustained write loads.

What is the typical fan noise and power draw when eight dual-slot GPUs and both EPYC 9004 CPUs run continuously?

With eight Gen5 GPUs and dual EPYC 9004 processors fully loaded, the system runs high-speed fans that produce significant noise and draws substantial power from the redundant supplies.
