Dell PowerEdge R960 compatible DDR5 ECC RDIMM

This 128GB registered DDR5 module is built for Dell PowerEdge R960 rack servers. It delivers 4800 MT/s speed with CL40 latency and on-die ECC for data integrity in enterprise workloads. The 4Rx4 organisation suits high-capacity configurations.

Thermals noise and power draw in normal use

Operating at 1.1V, the module runs without a heat spreader and relies on server chassis airflow for cooling. Registered buffering reduces electrical load on the memory controller during sustained operation. No acoustic output is generated by the memory itself.

What the bundled accessories

No accessories or software are included with the memory module. Compatibility is validated for the Dell PowerEdge R960 platform through stress testing under load. The module installs directly into a 288-pin DDR5 RDIMM slot.

Questions about this item

How do I install this 288-Pin DDR5 RDIMM in a Dell PowerEdge R960, and what step is often missed?

Align the notch on the module with the slot key, press firmly until both retention clips click, then verify in BIOS that the 128GB module registers at 4800 speed and 1.10V.

What maintenance or replacement will this 4Rx4 ECC registered module need over time?

No scheduled maintenance is required; if a correctable error count rises or the module fails POST, replace it with an identical 128GB DDR5 4800 4Rx4 RDIMM.

What limit appears first when this 1.1V DDR5 4800 RDIMM runs sustained heavy workloads?

The 40 CAS latency and 1.10V operating point set the thermal and timing envelope; sustained loads will hit latency and voltage limits before bandwidth saturates.
