GIGABYTE G494-ZB0-ACP2 barebone server 24 DIMM 8 GPU

4U dual-socket HPC barebone for eight Gen5 GPUs

This barebone server chassis accepts two AMD EPYC 9004 or 9005 processors and up to eight dual-slot PCIe Gen5 graphics cards. It targets high-performance computing and AI clusters that need dense GPU acceleration in a standard rack form factor. Buyers who need more than eight GPU slots or single-socket economy should look elsewhere. The platform supports 24 DDR5 RDIMM modules across twelve memory channels for large dataset handling.

Thermals noise and power at typical load

Dual 10 Gb/s LAN ports via Intel X710-AT2 provide high-throughput networking for distributed workloads. Two M.2 slots with PCIe Gen3 x4 and x1 interfaces allow fast boot or cache drives without occupying PCIe expansion slots. Power draw and acoustic output scale with the installed CPU and GPU configuration, so operators must plan cooling and electrical supply to match their specific component choices.

Sustained load behaviour with eight GPUs installed

When fully populated with eight GPUs such as NVIDIA H200 NVL or RTX PRO 6000 Blackwell Server Edition cards, the system relies on its 4U airflow design to maintain stable temperatures during extended training or inference runs. Conditional support for four-way NVLink bridges enables direct GPU-to-GPU communication for scalable model performance. Continuous operation at maximum density demands adequate rack-level cooling and power distribution infrastructure.
