OWC 32GB DDR4 2400MHz ECC Registered RDIMM 2R4D42R432GB memory upgrade

SKU CH-71DV-HV92X

32GB DDR4 2400MHz ECC registered RDIMM for compatible Supermicro server motherboards

  • Capacity32GB
  • Type288-Pin DDR4 ECC RDIMM
  • SpeedDDR4 2400 (PC4 19200)
  • CAS LatencyCL17
  • Voltage1.2V
  • ECCYes
  • 32 GB capacity expands server memory headroom
  • DDR4 2400 MHz CL17 delivers stable throughput
  • ECC registered design protects data integrity
  • 2 V operation reduces power draw
  • Validated for Supermicro X10DR series motherboards

System-specific server memory

This 32 GB DDR4 ECC registered DIMM is built for Supermicro X10 dual-socket motherboards including the X10DRFF-C, X10DRG-O+-CPU, X10DRG-OT+-CPU, X10DRH-CLN4 and X10DRH-iLN4. It targets administrators who need to expand capacity in validated server or workstation platforms.

Registered ECC design for 24/7 operation

The module runs at 2400 MHz with CL17 latency at 1.2 V using a 2Rx4 organisation across 288 pins. Registered buffering and on-die error correction protect data integrity under sustained loads, while the lack of a heat spreader keeps the profile low for dense chassis layouts.

Direct replacement for Supermicro MEM-DR432L series

It substitutes part numbers such as MEM-DR432LC-ER24, MEMDR432LCL01ER24 and MEMDR432LSV01ER24 without mixing with unbuffered DIMMs. The upgrade makes sense when adding nodes to an existing X10 cluster or maximising memory slots on a supported board.
