GIGABYTE G294-Z43-AAP2 barebone server 16 GPU 24 DIMM

SKU CH-4X19-SK368 MPN G294-Z43-AAP2

A 2U barebone server supporting dual AMD EPYC 9005/9004 processors, 24 DDR5 DIMM slots and 16 PCIe Gen5 GPU slots

  • Supports up to 16 single-slot Gen5 GPUs for massive parallel compute
  • Dual AMD EPYC 9005/9004 processors deliver high core-count performance
  • 12-channel DDR5 with 24 DIMM slots enables large memory capacity
  • 4 x 2.5" Gen5 NVMe/SATA/SAS-4 plus 4 x 2.5" SATA/SAS-4 hot-swap bays for flexible storage
  • Dual 10Gb/s LAN via Broadcom BCM57416 provides fast network connectivity

Dual AMD EPYC 9004/9005 platform

The GIGABYTE G294-Z43-AAP2 is a 2U barebone server designed for high-performance computing and AI workloads. It accommodates dual AMD EPYC 9004 or 9005 series processors to deliver dense multi-threaded performance. The chassis targets organisations building GPU-heavy clusters for training or inference. It is not suited for buyers who need integrated graphics or single-socket economy.

16 GPU slots with PCIe Gen5 switches

Sixteen full-height full-length PCIe Gen5 x16 slots connect through PCIe switches to support up to 16 single-slot Gen5 GPUs. Twelve-channel DDR5 RDIMM architecture populates 24 DIMM slots for high memory bandwidth. Storage uses four 2.5-inch Gen5 NVMe/SATA/SAS-4 hot-swap bays plus four 2.5-inch SATA/SAS-4 hot-swap bays. Dual 10Gb/s LAN ports via Broadcom BCM57416 handle data movement. Builders needing 3.5-inch drive carriers or additional network interfaces must look elsewhere.

Dual ROM firmware resilience

Dual ROM architecture provides fallback firmware for platform stability during long-running jobs. The 2U form factor concentrates 16 GPUs and 24 DIMMs, demanding robust facility cooling and power distribution. Sustained load across all GPUs and both CPUs will stress thermal and electrical infrastructure. Operators without redundant cooling or high-capacity PDUs should not deploy this density.

Highlights

  • Supports up to 16 single-slot Gen5 GPUs for massive parallel compute
  • Dual AMD EPYC 9005/9004 processors deliver high core-count performance
  • 12-channel DDR5 with 24 DIMM slots enables large memory capacity
  • 4 x 2.5" Gen5 NVMe/SATA/SAS-4 plus 4 x 2.5" SATA/SAS-4 hot-swap bays for flexible storage

Questions about this item

How many single-slot Gen5 GPUs can the G294-Z43-AAP2 accommodate at once?

The chassis provides 16 full-height, full-length PCIe Gen5 x16 slots, so up to 16 single-slot Gen5 GPUs can be installed simultaneously.

What is the thermal and acoustic profile when all GPU slots are populated under continuous load?

With dual EPYC 9005/9004 CPUs and 16 GPUs drawing sustained power, the 2U enclosure relies on high-speed system fans that generate significant noise and move large air volumes to keep components within thermal limits.

Which processors and memory must be sourced separately to make this barebone operational?

You need two AMD EPYC 9005 or 9004 series CPUs and up to 24 DDR5 RDIMM modules to fill the 12-channel memory architecture.
