Targeted Server Upgrade

This NEMIX RAM kit delivers 192GB of DDR5 ECC RDIMM capacity across two 96GB modules. It is built for the Supermicro AS-8126GS-NB3RT GPU A+ Server where registered memory is required. The modules operate at 1.1V with a CL52 latency rating.

Sustained Workload Stability

Registered buffering and on-die ECC protect data integrity during continuous compute tasks such as AI training or rendering. The 6400MHz transfer rate maintains bandwidth without voltage scaling beyond 1.10V. Dual-rank 2Rx4 organisation keeps signal loading predictable across all populated slots.

Capacity-Driven Compatibility

The 192GB total capacity is the specification that determines fit for memory-intensive server roles. Each 288-pin module uses major OEM DRAM from Samsung Micron or Hynix. Buyers needing a different total capacity or a non-registered DIMM type should select another kit.

Questions about this item

How much heat does the 1.1 V DDR5 kit produce when the AS-8126GS-NB3RT runs continuously?

At 1.1 V the modules draw very little power, so thermal output stays low even during sustained 24-hour workloads inside the Supermicro server.

Does the Supermicro AS-8126GS-NB3RT need a specific BIOS revision before I install these 2Rx4 RDIMMs?

The kit is validated for the AS-8126GS-NB3RT platform; install the modules in the correct slots and the server will recognise the 192 GB capacity at 6400 MHz.

Can I keep my existing DDR5 RDIMMs and add this 192 GB kit to the same AS-8126GS-NB3RT chassis?

Yes, the registered 288-pin DDR5 modules operate at 1.1 V and CL52, so they can populate free slots alongside other compatible DDR5 RDIMMs in the server.
