Exact-match 128GB DDR5 RDIMM kit

This NEMIX RAM kit delivers 128GB of DDR5 5600 PC5-44800 registered ECC memory across four 32GB 2Rx8 modules. Each DIMM operates at 1.1V with CL46 latency in the 288-pin RDIMM form factor required by the Supermicro X14SDV-36C-SP3F motherboard. The specification matches the board's memory controller expectations for rank, voltage and timing so the full capacity is recognised at rated speed. Samsung, Micron or Hynix chips provide enterprise-grade stability.

Suited for populated Supermicro X14SDV-36C-SP3F

Builders expanding a Supermicro X14SDV-36C-SP3F platform to its full 128GB registered ECC capacity will find the correct rank, voltage and form factor in this kit. The registered architecture offloads the memory controller allowing every slot to run fully populated while ECC corrects single-bit errors on the fly. Buyers who need unbuffered UDIMM or SODIMM modules should look elsewhere because this kit uses the 288-pin RDIMM form factor only.

2Rx8 registered ECC at 1.1V decides compatibility

The single specification that determines whether this kit works is the 2Rx8 registered ECC organisation running at 1.1V with CL46 timing. Your motherboard manual must confirm support for 2Rx8 registered DIMMs at DDR5 5600 PC5-44800 in the exact population order required. If the manual specifies a different rank configuration, voltage or unbuffered memory this kit will not function correctly.

Questions about this item

Will the 2Rx8 registered ECC modules need any firmware updates or scheduled replacement intervals?

The modules are built to JEDEC DDR5 specifications and carry a lifetime replacement warranty; no firmware updates or scheduled replacement intervals are required.

What limit appears first when the Supermicro X14SDV-36C-SP3F runs all 128 GB at DDR5 5600 continuously?

The board's memory-controller thermal ceiling is reached before the 1.10 V RDIMMs hit any electrical limit.

How much heat and power do four 32 GB 2Rx8 RDIMMs add during all-day operation?

Each stick runs at 1.10 V with no heat spreader; total draw stays within the DDR5 5600 registered DIMM envelope and airflow from the server chassis keeps temperatures in check.
