Dual EPYC 9575F GPU server

The Supermicro AS -4126GS-NBR-LCC-G1 is a 4U rack system built for large-scale AI and HPC workloads. It ships with two AMD EPYC 9575F processors, each delivering 64 cores at 3.30 GHz, plus eight NVIDIA HGX B200 GPUs providing 180 GB of video memory. The platform includes 3 TB of DDR5-6400 ECC memory and 4 x 15.3 TB U.2 NVMe SSDs with 2 x 960 GB M.2 NVMe boot drives.

Installation and common issues

The unit occupies a full 4U rack space and requires 2.5-inch drive bay compatibility for its eight front hot-swap NVMe slots. Four 6600 W redundant power supplies in a 2+2 Titanium configuration demand adequate PDU capacity and three-phase input planning. Five hot-swap 60 mm fans handle airflow, but GPU density means cable routing for the 8 x 400 Gb/s OSFP and BlueField-3 DPU links must be verified before power-on.

GPU memory capacity

The eight B200 GPUs deliver a combined 180 GB of HBM3e memory, which is the decisive figure for model size and batch throughput. Buyers training models that exceed this aggregate VRAM will need multi-node scaling or a different GPU configuration. The installed 3 TB of system DDR5-6400 supports CPU-side preprocessing but does not extend GPU memory.

Questions about this item

How can I verify the NVIDIA HGX B200 8-GPU baseboard with 180GB video memory is operating correctly after installation?

Check the system LEDs for network activity and UID status, confirm all 5 hot-swap 60mm fans are spinning, and use the NVIDIA BlueField-3 DPU 200Gb/s management interface to validate GPU detection and health.

What components are included and what must be sourced separately for the AS -4126GS-NBR-LCC-G1?

The server ships with dual EPYC 9575F 64-core CPUs, 3TB DDR5-6400 across 24 slots, 4x 15.3TB U.2 NVMe SSDs, 2x 960GB M.2 NVMe SSDs, the 8-GPU HGX B200 baseboard, 8x 400G NDR/ETH OSFP ports, 1x BlueField-3 DPU, and 4x 6600W Titanium redundant PSUs; no additional parts are required for the listed configuration.

Which memory capacity should I select between the installed 3TB and the maximum 6TB for this platform?

The system arrives with 3TB DDR5-6400 ECC RDIMM populated; choose the 6TB option only if your workload needs the full 24-slot capacity at 1DPC, otherwise the factory 3TB configuration is ready to run.
