GIGABYTE G294-Z41-AAP2 barebone server dual EPYC 9005/9004 24 DIMM 4 GPU

SKU CH-CZ3X-4PXCY MPN G294-Z41-AAP2

2U barebones server supporting dual EPYC 9005/9004 CPUs, 24 DDR5 DIMMs and four dual-slot Gen5 GPUs

  • Dual EPYC 9005/9004 CPUs power demanding HPC and AI workloads
  • 24 DDR5 RDIMM slots across 12 channels deliver massive memory bandwidth
  • Four dual-slot PCIe Gen5 GPUs accelerate training and inference
  • Four 2.5" Gen5 NVMe/SATA/SAS-4 plus four 2.5" SATA/SAS-4 hot-swap bays provide flexible storage
  • Dual 10Gb/s LAN via Broadcom BCM57416 ensures fast network connectivity

2U Dual EPYC GPU Server Barebone

The GIGABYTE G294-Z41-AAP2 is a 2U barebone server designed for dual AMD EPYC 9005 or 9004 series processors. It provides twelve-channel DDR5 memory across twenty-four DIMM slots and accommodates up to four dual-slot PCIe Gen5 GPUs. Dual 10GbE LAN ports and hot-swap drive bays complete the high-density compute platform.

HPC and AI clusters needing dense GPU compute

This system suits deployments that require four full-size Gen5 accelerators and maximum memory capacity per node. It is not for builds limited to single-socket processors, fewer than four GPUs, or workloads that do not need twelve-channel memory bandwidth. Buyers needing only air-cooled CPUs or smaller form factors should evaluate other chassis.

Four dual-slot Gen5 GPU capacity

The defining specification is support for four dual-slot PCIe Gen5 GPUs, including NVIDIA H200 NVL models, within a 2U envelope. This density determines whether the platform fits the target AI or HPC workload. Verify GPU power and thermal requirements against the chassis limits before deployment.

Questions about this item

How are the dual EPYC 9005 or 9004 processors installed, and which step is often missed?

Install both CPUs into the SP5 sockets, then populate all 12 DDR5 channels per processor with matched RDIMMs; the step often missed is filling every channel to avoid reduced memory bandwidth.

What maintenance will the 4 hot-swap 2.5-inch NVMe SATA SAS-4 drive bays need over time?

Monitor SMART data for each drive, replace any that report reallocated sectors, and keep firmware current; the backplane and cabling require no scheduled service.

What limit appears first when four dual-slot Gen5 GPUs run sustained workloads?

The 2U chassis airflow becomes the limiting factor; GPU boost clocks will throttle before the PCIe Gen5 x16 links or the 12-channel DDR5 memory subsystem saturate.
