NEMIX RAM 128GB DDR5 6400MHz ECC RDIMM kit

This NEMIX RAM kit provides 128GB of registered DDR5 memory across four 32GB modules. It runs at 6400MHz with a CL52 latency and operates at 1.1V. The kit is validated for the SuperMicro BigTwin SuperServer SYS-222BT-HER.

Suited for ECC registered DDR5 server upgrades

This memory fits administrators expanding capacity in compatible Supermicro systems that require registered ECC RDIMMs. It is not for platforms that only accept unbuffered UDIMMs or that lack DDR5 RDIMM support.

Registered ECC with 2Rx8 organisation

The modules use a 2Rx8 rank configuration and registered ECC circuitry, which the motherboard must support for the kit to function. Verify the platform accepts registered DDR5 RDIMMs before purchase.

Questions about this item

How does the CL52 latency affect sustained throughput on this DDR5 6400MHz kit?

CL52 is the CAS latency rating for these DDR5 6400MHz modules; lower latency can improve response times during sustained workloads.

What thermal load should I expect from four 32GB RDIMMs running at 1.1V continuously?

The kit operates at 1.1V with no heat spreader; registered DDR5 RDIMMs at this voltage typically run cool under continuous server loads.

Does the SuperMicro BigTwin SYS-222BT-HER require any specific BIOS setting to recognise this 2Rx8 ECC RDIMM kit?

This 128GB DDR5 ECC RDIMM kit is listed as compatible with the SuperMicro BigTwin SuperServer SYS-222BT-HER; consult the system manual for any required BIOS configuration.
