Dell PowerEdge R760xa memory kit

This 128 GB kit contains two 64 GB DDR5 registered DIMMs built for the Dell PowerEdge R760xa rack server. It targets IT teams expanding memory capacity in that specific platform.

ECC registered DDR5 at 4800 MT/s

The modules run at DDR5 4800 (PC5-38400) with CL40 latency, 2Rx4 organisation and on-die ECC. Registered buffering and error correction protect data integrity under sustained server workloads.

Low-voltage operation at 1.1 V

Each DIMM draws 1.10 V with no heat spreader, relying on the server's directed airflow for cooling. The reduced voltage and bare PCB keep power draw and acoustic impact minimal in dense rack deployments.

Questions about this item

Will the CL40 latency noticeably slow down my R760xa?

The modules run at DDR5 4800 with CL40 timing; the server's memory controller is validated for this speed and latency, so performance matches Dell's qualified configuration.

What does the PC5-38400 rating limit in practice?

PC5-38400 is the JEDEC standard name for DDR5 4800 bandwidth; the kit will not exceed 4800 MT/s on this platform.

Do the 288-pin RDIMMs fit the R760xa DIMM slots without a riser?

Yes, the 288-pin DDR5 RDIMM form factor is the native slot type for the PowerEdge R760xa, so they install directly.
