System-specific DDR5 kit

This NEMIX RAM kit provides 128GB of DDR5 memory in a matched pair of 64GB modules. It is built for the Supermicro SYS-222BT-HER BigTwin SuperServer and runs at 6400MHz with CL52 latency. The registered ECC design supports data integrity in enterprise workloads.

Pre-installation checks

Verify that the SYS-222BT-HER platform accepts 2Rx4 registered DIMMs at 1.1V and that all memory channels are populated according to the system manual. Confirm the motherboard firmware supports DDR5 6400MHz operation before fitting the modules.

Suitability

This kit suits administrators expanding Supermicro BigTwin nodes with validated ECC RDIMM capacity. It is not intended for desktop boards that require unbuffered non-ECC memory or for systems limited to lower-density ranks.

Questions about this item

Does the 128GB kit include both 64GB modules or do I need to order a second stick separately?

The package contains two 64GB modules, giving a total of 128GB in a single kit.

The listing shows CL52 and 6400MHz — which one should I prioritise for my Supermicro SYS-222BT-HER?

Both figures describe the same modules; they run at 6400MHz with a CAS latency of 52, so no choice between versions is needed.

What does the 6400MHz rating actually deliver once the RDIMMs are installed in the server?

The modules operate at 6400 MT/s (PC5-51200) with registered ECC at 1.1V, providing the rated bandwidth and error correction for the Supermicro BigTwin platform.
