NEMIX RAM 32GB DDR5 ECC RDIMM Kit

This 32GB kit contains two 16GB DDR5 ECC RDIMM modules rated at 6400MHz with CL52 latency. It is built for the SuperMicro BigTwin SuperServer SYS-222BT-HER and similar registered-memory platforms.

Installation notes for registered DDR5 modules

The 288-pin RDIMMs install in the server's DIMM slots like standard memory but the registered buffer requires the motherboard to support registered DIMMs. A common issue is mixing registered and unbuffered modules or populating slots in an order the board firmware does not expect.

Pre-order checklist for SuperMicro BigTwin

Verify that your SYS-222BT-HER or compatible SuperMicro system specifies DDR5 RDIMM support at 1.1V and accepts 1Rx8 rank configuration. Confirm the maximum memory capacity per channel and the required population sequence in the system manual before ordering.
