NEMIX RAM 32GB DDR5 6400 PC5-51200 2Rx4 CL52 1.1V ECC RDIMM memory upgrade for Supermicro X14SDV-42C-SP3F

SKU CH-M4WS-GMSJY

A 32 GB DDR5 6400 registered ECC RDIMM built for the Supermicro X14SDV-42C-SP3F with 2Rx4 rank, 1.1 V operation and CL52 timing

  • Total capacity32 GB
  • Rated speedDDR5 6400 (PC5 51200)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL52
  • Rated voltage1.1 V
  • Buffer typeRegistered

Size 32GB

  • Exact-match 32GB DDR5-6400 ECC RDIMM installs at rated speed
  • Registered 2Rx4 architecture keeps every slot stable at full capacity
  • On-die ECC corrects single-bit errors preventing silent data corruption
  • 1V CL52 timing matches Supermicro X14SDV-42C-SP3F memory controller specs
  • 288-pin RDIMM form factor fits the board's required DIMM population rules

Targeted Server Upgrade

This 32GB DDR5 6400 registered ECC RDIMM is built for the Supermicro X14SDV-42C-SP3F motherboard. It matches the exact rank, voltage and timing the board expects so the memory controller recognises the full capacity at rated speed. The 288-pin RDIMM form factor is the only type this platform accepts.

Verified Compatibility

The module uses major OEM chips from Samsung, Micron or Hynix and carries the part number MR51200-324K1. No heat spreader is included, keeping the profile compatible with dense server layouts. Buyers must still consult their system manual for supported capacities, approved population order and installation steps before fitting.

Capacity And Limits

A single 32GB stick runs at 1.1V with CL52 latency and 2Rx4 organisation. Registered architecture offloads the memory controller so every slot can be populated at full capacity while ECC corrects single-bit errors on the fly. It will not fit boards that require UDIMM or SODIMM modules.

Questions about this item

Will the 32GB DDR5 6400 RDIMM need any firmware updates or periodic replacement?

No firmware updates are required for this DDR5 module. It is a solid-state component with no moving parts, so it does not have a scheduled replacement interval under normal server operation.

What limit appears first when the 2Rx4 ECC RDIMM runs continuously at 1.1V?

The thermal limit of the DRAM chips is reached before voltage or timing margins, since the module has no heat spreader and relies on chassis airflow to stay within JEDEC operating temperature.

How much noise and heat does the 288-pin Registered DIMM add when the server runs all day?

The module itself is silent and draws 1.1V at DDR5-6400; any audible noise or measurable heat rise comes from the system fans working to cool the bare DRAM packages.
