NEMIX RAM

NEMIX RAM 128GB DDR5 5600 CL46 4Rx4 RDIMM memory upgrade

SKU CH-Q6VY-HZK4E

128GB DDR5 5600 ECC registered RDIMM with CL46 latency and 1.1V operation, validated for Supermicro X14SDW-40C-SP9F motherboards

  • Capacity128GB
  • Type288-Pin DDR5 RDIMM
  • SpeedDDR5 5600 (PC5 44800)
  • CAS LatencyCL46
  • Voltage1.10V
  • ECCYes

Size 128GB

  • 128 GB capacity maximises server memory density
  • DDR5 5600 speed matches platform rated frequency
  • CL46 latency meets controller timing requirements
  • 4Rx4 registered ECC architecture enables full-slot population
  • 1 V operation aligns with motherboard voltage spec

Server DDR5 ECC RDIMM upgrade

This NEMIX RAM module adds 128 GB of DDR5 memory to compatible Supermicro platforms. It operates at 5600 MT/s with CL46 latency and a registered ECC design that protects data integrity. The 4Rx4 organisation and 1.1 V voltage match the board's native requirements.

Replaces slower or smaller DDR5 DIMMs

Swapping out lower-capacity or lower-speed DDR5 RDIMMs lets every populated slot run at the rated 5600 MT/s without downclocking. The jump is worthwhile when your workload needs the full 128 GB per module and the registered buffer to keep all channels stable at maximum population.

Suits Supermicro X14SDW-40C-SP9F builders

This kit fits administrators expanding that specific motherboard with validated DDR5 RDIMMs. It is not for systems that require UDIMM or SODIMM form factors, nor for boards that do not support 4Rx4 registered ECC modules at 1.1 V.

Highlights

  • DDR5 5600 speed matches platform rated frequency
  • CL46 latency meets controller timing requirements
  • 4Rx4 registered ECC architecture enables full-slot population

Questions about this item

Will the 288-pin DDR5 RDIMM fit the Supermicro X14SDW-40C-SP9F motherboard?

Yes, the module uses the 288-pin DDR5 RDIMM form factor that the X14SDW-40C-SP9F requires; it is not a UDIMM or SODIMM.

What is the correct slot order when installing this 4Rx4 registered DIMM on the X14SDW-40C-SP9F?

Consult the motherboard manual for the approved DIMM population sequence; fully populated registered slots must follow the board's specific installation steps.

Does this 128GB kit require any firmware updates or ongoing maintenance after installation?

No firmware updates are needed for the memory itself; ECC corrects single-bit errors automatically, and the module carries a lifetime replacement warranty if a fault ever occurs.
