NEMIX RAM MR44800-328K4 128GB (4x32GB) DDR5 5600 CL46 1.1V ECC RDIMM Supermicro H14SSF

Exact-match server kit

This 128GB kit contains four 32GB DDR5-5600 Registered ECC RDIMMs built to the precise rank, voltage and timing the Supermicro H14SSF memory controller expects. Each module runs at 1.1V with CL46 latency and a 2Rx8 organisation so the board recognises the full capacity at rated speed. The 288-pin registered form factor matches the slots this motherboard requires.

Sustained-load behaviour

Registered architecture offloads the memory controller, allowing every slot to stay fully populated at full capacity without signal degradation. ECC circuitry catches and corrects single-bit errors on the fly, preventing silent data corruption and unplanned reboots during continuous production workloads. The 1.1V operating voltage keeps power draw predictable under long-running jobs.

Upgrade context

This kit replaces smaller or slower DDR5 RDIMM sets when the H14SSF platform needs maximum registered ECC capacity in a four-module population. The jump is worth it when workloads demand the full 128GB at 5600 MT/s with verified population-rule compliance. Buyers who need UDIMM, SODIMM or non-ECC memory cannot use this kit.
