NEMIX RAM DDR5 6400 128GB (8x16GB) CL52 1.1V ECC RDIMM Supermicro H14DSH

128GB DDR5-6400 ECC RDIMM kit for Supermicro H14DSH

This 128GB kit contains eight 16GB DDR5-6400 Registered ECC RDIMMs built for the Supermicro H14DSH motherboard. Each module runs at 1.1V with CL52 latency and a 1Rx8 organisation. The registered design lets the memory controller address every slot at full capacity. System administrators upgrading H14DSH servers to the maximum supported population will find the exact rank, voltage and timing the board expects.

288-pin Registered form factor with major-brand DRAM

The modules use a standard 288-pin DDR5 RDIMM connector that matches the H14DSH DIMM slots — not a UDIMM or SODIMM footprint. Chips are sourced from Samsung, Micron or Hynix depending on production lot. No heat spreader is fitted, so airflow in dense server chassis is unimpeded. The registered buffer reduces electrical load on the memory controller when all channels are populated, while on-die ECC corrects single-bit errors before they reach the operating system.

Replaces smaller or mixed-capacity DDR5 RDIMM sets

Installing this kit removes the need to combine modules of different capacities or ranks, which can force the motherboard to run at reduced speeds or disable slots. The jump is worth it when the workload demands the full 128GB at the board's native DDR5-6400 rate with ECC protection active. Buyers who need a different total capacity, a UDIMM form factor or non-ECC memory should look elsewhere.
