Supermicro AS -4125GS-TNRT-G1 rack server dual EPYC 9124 16C 3.00GHz 1.5TB DDR5 1.9TB NVMe 2x L40S

Dual EPYC 9124 GPU Server

This 4U rack system ships with two AMD EPYC 9124 processors, each running at 3.00 GHz with 16 cores, plus two NVIDIA L40S PCIe graphics cards. It arrives with 1.5TB of DDR5-5600 memory installed across 24 slots and a 1.9TB U.2 NVMe SSD. Four hot-swap 2.5-inch NVMe bays and two hot-swap 2.5-inch SATA bays sit at the front, while an M.2 PCIe 3.0 x4 slot is also available. Onboard dual 10GbE RJ45 and four 2000W Titanium power supplies complete the platform.

Suited for dense GPU workloads.

The dual-socket design and twin GPUs suit training, inference and simulation jobs that scale across high core counts and memory bandwidth. Eight heavy-duty fans with optimal speed control keep thermals in check under sustained load. Buyers who need a quiet tower chassis or a single-socket platform with lower power draw should look at something else. The 4U height also rules out shallow racks or space-constrained cabinets.

Memory ceiling of 8TB

The board supports up to 8TB of ECC DDR5 RDIMM across the 24 DIMM slots, running at 4800MT/s with the installed EPYC 9004 series processors and at 6000MT/s with EPYC 9005 series processors. This capacity limit is the primary factor when planning large in-memory databases or multi-tenant virtualisation clusters.
