OWC 32GB DDR5 4800 CL40 1Rx4 288-pin 1.1V ECC Registered RDIMM server RAM

SKU CH-15PD-24D6P

32 GB DDR5 ECC registered RDIMM running at 4800 MT/s with CL40 latency for server workloads

  • Capacity32GB
  • Type288-Pin DDR5 ECC RDIMM
  • SpeedDDR5 4800 (PC5 38400)
  • CAS LatencyCL40
  • Voltage1.1V
  • ECCYes
  • ECC registered design protects data integrity in servers
  • 32 GB capacity expands memory for heavy workloads
  • DDR5 4800 speed delivers high bandwidth performance
  • CL40 latency at 1.1 V balances timing and power
  • JEDEC compliant module ensures broad server compatibility

Server memory for workstations

This 32GB DDR5 module is built for workstations and servers that require registered ECC memory. It will not work in standard desktop computers and cannot be mixed with unbuffered or load-reduced modules.

288-pin registered DIMM without heat spreader

The module uses a 288-pin DDR5 interface at 1.1V with CL40 latency and a 1Rx4 rank configuration. The bare PCB design fits dense server slots where tall heat spreaders would block adjacent modules or airflow.

Replaces Micron MTC18F1045S1PC48B

This module matches the Micron part numbers listed and meets JEDEC PC5-38400 specifications. The upgrade is worthwhile when expanding capacity in a compatible platform or when a registered ECC DIMM has failed and a validated replacement is required.

Perguntas sobre este artigo

Does the DDR5 4800 CL40 rating limit real-world bandwidth on a registered DIMM?

The module operates at 4800 MT/s with CL40 timing; registered buffering adds one cycle, so sustained throughput is set by the platform's memory controller and channel count.

Will the 288-pin 1.1 V RDIMM fit a standard server DIMM slot?

Yes — it uses the standard 288-pin DDR5 RDIMM form factor and 1.1 V signalling, matching the mechanical and electrical keying of compliant server slots.

What is the correct installation sequence for this 1Rx4 ECC registered module?

Power down, open the chassis, align the notch with the slot key, press firmly until both latches click, then populate remaining slots per the motherboard's channel guide to enable ECC.
