NEMIX RAM 96GB DDR5 ECC RDIMM Kit

This 96GB kit contains six 16GB DDR5 4800 RDIMM modules with ECC and registered buffering. It operates at 1.1V with CL40 latency and uses a 288-pin form factor. The memory is validated for SuperMicro Hyper SuperServer SYS-121H-TNR, SYS-221H-TNR and SYS-221H-TN24R systems.

Administrators expanding SuperMicro DDR5 servers

IT teams scaling memory in the listed SuperMicro Hyper SuperServer models will find a direct-fit, tested kit. Builders needing unbuffered UDIMMs, non-ECC modules, different speeds, or compatibility with other server platforms should look elsewhere.

Six 16GB modules deliver 96GB total capacity

The kit provides 96GB across six 1Rx8 RDIMMs, enabling high-density population of available DIMM slots. This specific module count and per-stick density determine whether the target server reaches its desired memory ceiling.

Questions about this item

Which SuperMicro Hyper SuperServer models is this 96GB DDR5 4800 ECC RDIMM kit validated for?

The kit is compatible with SuperMicro SYS-121H-TNR, SYS-221H-TNR and SYS-221H-TN24R servers.

Can I mix these CL40 1Rx8 registered modules with existing DDR5 ECC RDIMMs of different speeds or ranks in the same server?

Mixing speeds, ranks or CAS latencies is not recommended; the system will run all modules at the slowest common settings and may disable ECC or registered features.

How do I confirm the full 96GB is recognised and ECC is active after installation?

Check the BIOS memory summary for 96GB total, verify DDR5 4800 MT/s speed, and ensure ECC status shows enabled or active.
