OWC 32GB DDR5 4800 PC5-38400 CL40 2Rx8 288-pin 1.1V ECC Registered RDIMM Memory Upgrade

SKU CH-0BMN-EWAF5

A 32 GB DDR5 ECC registered RDIMM running at 4800 MHz CL40 for Dell PowerEdge R760xd2 servers

  • Total capacity32 GB
  • Rated speedDDR5 4800 (PC5 38400)
  • CAS latencyCL40
  • Rated voltage1.1 V
  • Buffer typeRegistered
  • Memory rank2Rx8

Capacity 32GB

  • ECC registered design protects data integrity in servers
  • 32 GB DDR5 module runs at 4800 MT/s with CL40 latency
  • Low 1.1 V voltage reduces power draw in dense configurations
  • 2Rx8 dual-rank layout increases memory density per slot
  • Validated for Dell PowerEdge R760xd2 and replaces part AC239378

Server-Grade DDR5 Module

This 32 GB DDR5 ECC registered DIMM is built for Dell PowerEdge R760xd2 servers and compatible workstations. It delivers error-correcting, registered memory for workloads that demand data integrity and uptime. The module is not compatible with standard desktop computers or unbuffered memory configurations.

32 GB Capacity at 4800 MT/s

A single 2Rx8 module runs at PC5-38400 with CL40 latency and 1.1 V, providing substantial headroom for virtualization, databases and large datasets. Performance scales with additional modules, but mixing with load-reduced or unbuffered DIMMs is not supported and will prevent operation.

288-Pin RDIMM Form Factor

The module fits standard DDR5 RDIMM slots in the R760xd2 and replaces Dell part AC239378. No heat spreader is included, so airflow across the DIMM bays must be maintained by the server chassis. Installation requires no extra cables or adapters beyond the memory slots themselves.

Questions about this item

Will this DDR5 4800 CL40 RDIMM run alongside existing DDR5 4800 registered ECC modules in my R760xd2?

Yes — the module is built to JEDEC DDR5 4800 CL40 1.1 V registered ECC spec, so it will operate with identical DDR5 4800 registered ECC DIMMs already installed in the PowerEdge R760xd2.

How can I verify the 32 GB DDR5 4800 CL40 RDIMM is detected at full speed after installation?

Check the system BIOS or iDRAC memory inventory; it should show a single 32 GB DDR5 4800 MT/s registered ECC DIMM running at 1.1 V with CL40 timings.

Does the box contain only the 288-pin DDR5 4800 CL40 RDIMM, or are any brackets or cables included?

The upgrade consists of the single 32 GB 288-pin DDR5 4800 CL40 2Rx8 registered ECC RDIMM; no brackets, cables or additional hardware are supplied.
