NEMIX RAM 64GB DDR5 6400 CL52 4Rx4 1.1V RDIMM ECC memory upgrade for Supermicro X14SDW-36CE-SP9F

SKU CH-0WH1-RQPFC

64 GB DDR5 6400 CL52 4Rx4 1.1 V registered ECC RDIMM validated for the Supermicro X14SDW-36CE-SP9F motherboard

  • Capacity64GB
  • Type288-Pin DDR5 RDIMM
  • SpeedDDR5 6400 (PC5 51200)
  • CAS LatencyCL52
  • Voltage1.10V
  • ECCYes

Size 64GB

  • 64 GB capacity lets you fully populate server slots with 4Rx4 registered DIMMs
  • DDR5-6400 speed rated at CL52 latency keeps data flowing at PC5-51200 bandwidth
  • 10 V operation reduces power draw while maintaining stability across all populated channels
  • ECC registered design detects and corrects single-bit errors to prevent silent data corruption
  • 288-pin RDIMM form factor matches Supermicro X14SDW-36CE-SP9F memory population rules exactly

Exact-match DDR5 upgrade for Supermicro X14SDW

This 64GB DDR5-6400 RDIMM delivers the precise rank, voltage, and timing the X14SDW-36CE-SP9F memory controller expects. Registered ECC architecture offloads the controller so every populated slot runs at full rated speed. Single-bit errors are corrected on the fly to prevent silent data corruption.

Registered RDIMM build with 288-pin DDR5 interface

The module uses a registered design that buffers address and command signals, allowing full-capacity operation across all supported slots. ECC circuitry catches and corrects single-bit errors before they reach production workloads. The 1.10V operating voltage matches the platform specification exactly.

Replaces lower-capacity or non-ECC DDR5 modules

Upgrading to this 64GB 4Rx4 kit is worthwhile when the workload demands maximum registered memory capacity with error correction. Systems that require unbuffered UDIMMs or SODIMM form factors cannot use this module. Builders needing different rank configurations should verify the motherboard population rules first.

Questions about this item

What DDR5 speed and CAS latency does this 64GB RDIMM run at?

The module operates at DDR5 6400 (PC5-51200) with a CAS latency of CL52, so the memory controller sees its rated 6400 MT/s transfer rate and 52-cycle timing.

Does this kit need a 288-pin RDIMM slot and registered ECC support on the Supermicro X14SDW-36CE-SP9F?

Yes — it is a 288-pin DDR5 RDIMM with 4Rx4 registered ECC, the exact form factor and buffering the X14SDW-36CE-SP9F requires; UDIMM or SODIMM modules will not fit or function.

What population-order step do installers most often miss when adding this 4Rx4 module to the Supermicro board?

The manual specifies a strict DIMM slot sequence for 4Rx4 registered DIMMs; skipping the prescribed order leaves slots unrecognised or forces reduced speed, so follow the board’s population chart before powering on.
