OWC 32GB DDR4 2933MHz ECC Registered RDIMM 2Rx4 CL21 1.2V 288-pin for Dell PowerEdge XR4510c XR4520c

SKU CH-AACD-244EM

32 GB DDR4 2933 MHz ECC registered RDIMM for Dell PowerEdge XR4510c and XR4520c servers

  • Capacity32GB
  • Type288-Pin DDR4 ECC RDIMM
  • SpeedDDR4 2933 (PC4 23400)
  • CAS LatencyCL21
  • Voltage1.2V
  • ECCYes

Capacity 32GB

  • 32 GB capacity expands server memory for larger workloads
  • ECC registered design detects and corrects data errors for reliability

Server memory upgrade for Dell PowerEdge

This 32GB DDR4 ECC registered RDIMM runs at 2933MHz with CL21 latency and 1.2V operation. It is built specifically for Dell PowerEdge XR4510c and XR4520c servers and carries OWC part number 2R9D42R432GB. The module uses a 2Rx4 rank configuration and a standard 288-pin form factor.

For server and workstation builders only

This memory suits administrators upgrading or repairing the listed Dell PowerEdge models, or deploying compatible workstation and NAS systems that require registered ECC DDR4. It will not work in standard desktop computers and cannot be mixed with unbuffered modules. Buyers needing consumer DIMMs should look elsewhere.

Steady throughput at rated speed

The module operates at PC4-23400 bandwidth with backward compatibility to 2133MHz, 2400MHz and 2666MHz speeds. Under sustained workloads it maintains the specified 2933MHz frequency and CL21 timing at 1.2V. ECC registration provides continuous error correction for data integrity during extended operation.

Highlights

  • 2933 MHz DDR4 speed with CL21 latency delivers responsive performance
  • 2 V operation reduces power draw in dense configurations
  • Compatible with Dell PowerEdge XR4510c and XR4520c systems

Questions about this item

Does the Dell PowerEdge XR4510c need to support registered ECC DDR4 RDIMMs for this 32GB 2Rx4 module to work?

Yes, the server must accept 288-pin DDR4 ECC registered RDIMMs running at 1.2V; this module will not work in systems that only take unbuffered or non-ECC memory.

Can I add this 2933MHz CL21 RDIMM alongside existing 2400MHz or 2666MHz DDR4 ECC registered modules in the XR4520c?

The module is backward compatible with 2133MHz, 2400MHz and 2666MHz DDR4 ECC registered DIMMs, so it will run at the speed of the slowest installed kit.

How can I confirm the XR4510c recognises the full 32GB capacity and ECC function after installing this 2R9D42R432GB module?

Check the system BIOS or iDRAC memory inventory — it should show 32GB per DIMM at 2933MHz with ECC registered status and no correctable error count climbing.
