ECC RDIMM kit for Supermicro GPU servers

This 128 GB kit ships as four 32 GB DDR5 modules rated at 6400 MHz with CL52 latency. Registered design and on-die ECC protect data integrity in the SuperMicro GPU SuperServer SYS-422GS-NBRT-LCC platform.

Capacity and headroom

Four ranks of 2Rx8 chips deliver 128 GB at 1.1 V, giving ample headroom for virtualisation hosts and GPU-accelerated workloads. The kit fills four slots; further expansion requires replacing modules rather than adding to empty sockets.

Build integration

Modules use the standard 288-pin DDR5 RDIMM form factor and need a motherboard that supports registered ECC memory at 6400 MHz. No heat spreaders are fitted, so airflow across the DIMM area must be sufficient for sustained server operation.
