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

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.
