SuperMicro DDR5 ECC RDIMM Upgrade

This NEMIX RAM module adds 32GB of DDR5 4800 registered ECC memory to compatible SuperMicro servers. It operates at 1.1V with CL40 latency and a 1Rx4 organisation. The 288-pin RDIMM is built for mission-critical workloads that demand error correction and signal integrity.

Replaces Slower or Smaller DDR5 RDIMMs

The jump is worthwhile when a SuperMicro Hyper SuperServer such as the SYS-121H-TNR, SYS-221H-TNR or SYS-221H-TN24R needs higher capacity per slot or a move from lower-speed DDR5. Each module delivers PC5-38400 bandwidth while maintaining registered buffering for platform stability.

Suits IT Teams Expanding SuperMicro Memory

Administrators scaling memory in the listed SuperMicro platforms will find validated compatibility and rigorous stress testing. Builders requiring unbuffered UDIMMs, non-ECC modules, different voltages or form factors such as SO-DIMM should look elsewhere.

Questions about this item

Will this 288-pin DDR5 RDIMM fit the memory slots on my SuperMicro SYS-121H-TNR server?

Yes, the module uses the standard 288-pin DDR5 RDIMM form factor required by the SYS-121H-TNR and SYS-221H-TNR series.

Do I need to configure anything in the BIOS after installing this ECC registered memory, or is it plug-and-play?

The module runs at 4800 MT/s with CL40 timings at 1.1 V; most SuperMicro boards apply these JEDEC defaults automatically on first boot.

Since there is no heat spreader, will the Samsung, Micron or Hynix chips need active airflow to stay within safe temperatures?

Registered DDR5 DIMMs are designed for server chassis with directed airflow; ensure front-to-rear cooling passes over the memory slots.
