NEMIX RAM 32GB DDR5 6400 CL52 2Rx4 1.1V ECC RDIMM Supermicro X14SDW-40C-SP9F memory upgrade

SKU CH-DNC0-HTEZ1

32GB DDR5 6400 CL52 2Rx4 1.1V ECC registered RDIMM validated for the Supermicro X14SDW-40C-SP9F motherboard

  • Capacity32GB
  • Type288-Pin DDR5 RDIMM
  • SpeedDDR5 6400 (PC5 51200)
  • CAS LatencyCL52
  • Voltage1.10V
  • ECCYes

Size 32GB

  • 32 GB DDR5-6400 RDIMM expands server memory capacity
  • CL52 latency and 1.1 V operation match the Supermicro X14SDW-40C-SP9F memory controller
  • 2Rx4 registered architecture enables full-slot population at rated speed
  • ECC protection corrects single-bit errors to prevent silent data corruption
  • 288-pin DDR5 form factor fits the board's RDIMM slots exactly

Exact-match DDR5 upgrade for Supermicro

This 32 GB DDR5 6400 CL52 2Rx4 1.1 V ECC RDIMM is built to the precise rank, voltage and timing the Supermicro X14SDW-40C-SP9F memory controller expects. It installs as a 288-pin registered DIMM so the board recognises the full capacity at its rated speed without manual tuning.

Sustained-load behaviour with registered ECC

Registered architecture buffers the command and address signals, letting every populated slot run at the full 6400 MT/s data rate without loading down the controller. On-die ECC corrects single-bit errors on the fly, preventing silent data corruption and unplanned reboots during continuous server workloads.

The deciding spec: 2Rx4 registered ECC at 1.1 V

Your motherboard requires a 288-pin RDIMM with exactly this rank configuration, voltage and CAS latency; a UDIMM, SODIMM or different rank layout will not be recognised. Builders who need non-ECC unbuffered modules or a different voltage must choose a different part.

Questions about this item

How much power does the 1.1 V DDR5 module draw under continuous load?

It operates at 1.1 V, the standard DDR5 voltage, and the registered design reduces electrical load on the memory controller during all-day operation.

Does the Supermicro X14SDW-40C-SP9F motherboard need to be populated in a specific order for this 2Rx4 kit?

The board requires 288-pin RDIMMs and has its own population rules; consult the motherboard manual for the approved DIMM installation sequence.

Can I mix this 2Rx4 registered ECC module with 1Rx8 registered ECC DIMMs in the same server?

Mixing different rank organisations is not recommended; the memory controller expects uniform 2Rx4 registered ECC modules for stable full-capacity operation.
