768GB DDR5 ECC RDIMM Kit for Supermicro

This kit provides 768GB of registered DDR5 memory across six 128GB modules. It is built for the Supermicro GPU A+ Server AS-8126GS-NB3RT and similar enterprise platforms that require ECC RDIMM modules. The registered design helps maintain signal integrity in dense configurations.

DDR5 6400 CL52 at 1.1V with 2Rx4 organisation

The modules operate at 6400 MT/s with a CAS latency of 52 cycles and a voltage of 1.1V. Each module uses a dual-rank 2Rx4 layout on a 288-pin form factor. System memory controllers must support this speed, latency and rank structure for stable operation.

Six-module 768GB capacity requires full population

The kit delivers its rated capacity only when all six DIMM slots are filled with the supplied 128GB sticks. Partial population will reduce total memory and may alter channel balance. Buyers needing a different total capacity should select a kit matched to their target configuration.

Questions about this item

Should I choose the 6x128GB kit or a different capacity for my SuperMicro AS-8126GS-NB3RT?

The kit provides 768GB total across six 128GB modules. Select it when your workload needs that full capacity and the server has six available DDR5 RDIMM slots.

What does the 6400MHz rating deliver once the memory is installed in the AS-8126GS-NB3RT?

The modules run at DDR5-6400 with CL52 latency at 1.1V, giving the server its rated bandwidth and error-correcting registered operation for the GPU A+ platform.

How does the DDR5 RDIMM interface and PC5-51200 standard limit performance in this server?

The 288-pin DDR5 RDIMM form factor and PC5-51200 designation set the electrical and mechanical interface; the server's memory controller determines the final speed and timing achieved.
