OWC 64GB DDR5 4800 CL40 2Rx4 288-pin 1.1V ECC Registered RDIMM for Dell PowerEdge XE9680 memory upgrade

SKU CH-VKE1-PQA6N

Adds 64 GB of DDR5 4800 ECC registered memory to a Dell PowerEdge XE9680 server

  • Total capacity64 GB
  • Rated speedDDR5 4800 (PC5 38400)
  • CAS latencyCL40
  • Rated voltage1.1 V
  • Buffer typeRegistered
  • Memory rank2Rx4

Capacity 64GB

  • 64GB capacity expands Dell PowerEdge XE9680 memory resources
  • DDR5 4800 speed with CL40 latency supports high-throughput workloads
  • ECC registered design detects and corrects data errors
  • 1V operation reduces power draw in dense server configurations
  • 2Rx4 288-pin RDIMM form factor matches OEM slot requirements

Server memory upgrade

This 64GB DDR5 registered DIMM is built for the Dell PowerEdge XE9680 and delivers ECC error correction for server workloads. It operates at 4800 MT/s with CL40 latency and a 1.1V supply. The module uses a 2Rx4 organisation and a standard 288-pin form factor. It is intended for administrators expanding capacity in supported PowerEdge systems.

Compatibility check

Verify that your XE9680 currently runs registered ECC DDR5 and that free 288-pin slots remain. This module will not work in unbuffered or load-reduced memory configurations and cannot be mixed with those types. Confirm the system BIOS supports 64GB single-rank densities before installation. The part replaces Dell part numbers AC239379 and SNPJ52K5C/64G.

Upgrade perspective

The jump makes sense when existing registered ECC modules are at lower capacity or slower speed and the platform can address the full 64GB per slot. It is not for desktop PCs, consumer workstations or any system requiring unbuffered memory. Builders needing load-reduced DIMMs or non-ECC modules should look elsewhere.

Questions about this item

Does the box contain only the 64GB DDR5 4800 CL40 ECC Registered RDIMM or are any cables or brackets included?

The package contains a single 64GB DDR5 4800 PC5-38400 CL40 2Rx4 288-pin 1.1V ECC Registered RDIMM module. No cables, brackets or additional hardware are supplied.

Should I choose the 2Rx4 registered version or is there an unbuffered alternative for the PowerEdge XE9680?

The PowerEdge XE9680 requires registered ECC memory. This 2Rx4 RDIMM is the correct type; unbuffered or load-reduced modules are not compatible and must not be mixed.

What does the 4800 PC5-38400 rating mean once the module is installed in the XE9680?

The module runs at 4800 MT/s with CL40 latency at 1.1V, delivering PC5-38400 bandwidth when the server's memory controller operates at the standard DDR5 4800 speed.
