System-specific DDR5 ECC RDIMM kit

This NEMIX RAM kit delivers 256 GB of DDR5 registered ECC memory across two 128 GB modules. It is built for the Supermicro GPU SuperServer SYS-422GS-NBRT-LCC and targets administrators who need maximum capacity with error correction for virtualisation, GPU compute or database workloads.

Verify DDR5 RDIMM support and slot population

Confirm the server runs a platform that accepts DDR5 registered DIMMs at 6400 MT/s with CL52 latency and 1.1 V operation. The board must provide 288-pin DDR5 slots and its BIOS must recognise 2Rx4 organisation. Check the vendor memory-qualified list for the exact SYS-422GS-NBRT-LCC revision before ordering.

Fills two RDIMM slots with registered ECC modules

Each module occupies one 288-pin DDR5 slot and draws 1.1 V, leaving remaining slots free for further expansion up to the platform limit. Registered buffering reduces electrical load on the memory controller, while on-die ECC protects data integrity without consuming extra bandwidth. The kit adds 256 GB in a matched pair for dual-channel operation.

Questions about this item

Does the kit include both 128 GB modules or must they be purchased separately?

The kit contains two 128 GB modules for a total of 256 GB, so no additional modules are required.

Should I choose the CL52 6400 MHz version or a lower-latency alternative for the SYS-422GS-NBRT-LCC?

This kit is specified at CL52 and 6400 MHz; the Supermicro SYS-422GS-NBRT-LCC is qualified for that speed and latency.

What does the 6400 MHz rating mean once the memory is installed in the Supermicro server?

The modules will run at 6400 MT/s with CL52 timing at 1.1 V, delivering the rated PC5-51200 bandwidth in the qualified platform.
