NEMIX RAM DDR5 ECC RDIMM 128GB 6400MHz CL52 1.1V 2Rx4 Supermicro H14SSL-NT

Exact-match DDR5 server memory

This NEMIX RAM module delivers 128GB of DDR5 ECC registered memory at 6400MHz with CL52 latency and 1.1V operation. It is built as a precise upgrade for the Supermicro H14SSL-NT motherboard, matching the rank, voltage and timing the memory controller expects. The 2Rx4 organisation allows full-capacity recognition across populated slots.

288-pin RDIMM form factor

The 288-pin registered DIMM fits only motherboards that require RDIMM modules, not UDIMM or SODIMM variants. Registered architecture buffers address and command signals so the memory controller can drive every slot at rated speed when fully populated. Major OEM chips from Samsung, Micron or Hynix provide the underlying silicon.

Enterprise stability with ECC

On-die ECC detects and corrects single-bit errors in real time, preventing silent data corruption and unplanned reboots in production workloads. The 1.1V operating voltage keeps power draw low for dense server configurations. No heat spreader is fitted, so airflow across the bare PCB is required for thermal management.
