Dell R760xa server upgrade

This 128GB DDR5 module is built for the Dell PowerEdge R760xa rack server. It delivers registered ECC memory for workloads that require data integrity and high capacity in a single slot. IT teams use it to expand memory density without adding modules.

Thermals and power

The module runs at 1.1V with no heat spreader, relying on the server's directed airflow for cooling. Registered buffering and ECC add minimal overhead while maintaining signal integrity under sustained load. Power draw stays consistent with standard DDR5 RDIMM operation.

Build integration

The 288-pin RDIMM fits directly into the R760xa memory slots and operates at 4800MHz CL40 with 4Rx4 organization. It frees additional DIMM slots for future expansion while providing 128GB per module. Buyers needing non-ECC memory or desktop form factors cannot use this module.

Preguntas sobre este artículo

How do I install the 288-pin DDR5 RDIMM in a Dell PowerEdge R760xa, and which step is most often missed?

Power down the server, open the chassis, locate the DDR5 slots, align the notch on the 288-pin module with the slot key, press firmly until the ejector clips click, then verify the new 128GB capacity in the BIOS or iDRAC — the step most often missed is confirming the module is fully seated by checking both clips are locked.

What maintenance or replacement will this 4Rx4 ECC registered module need over its service life?

No scheduled maintenance is required; the module has no heat spreader and operates at 1.10V, so keep the server air filters clean and monitor ECC corrected-error counters in the system log — if uncorrectable errors appear, replace the DIMM.

What limit appears first when this CL40 4800 MT/s module runs sustained workloads?

The CAS latency of CL40 at 4800 MT/s sets the baseline response time; under continuous heavy load the memory controller’s thermal throttling or the 1.1V voltage regulator’s current limit will typically cap sustained throughput before the module itself reaches a hard limit.
