Dell PowerEdge R960 compatible kit

This 64GB kit contains four 16GB DDR5 4800 registered DIMMs built for the Dell PowerEdge R960 rack server. Each module runs at 1.10V with CL40 latency and uses a 1Rx8 organisation. The 288-pin RDIMM form factor fits the server's registered memory slots.

ECC registered operation changes data integrity

On-die ECC and register buffering correct single-bit errors and reduce electrical load on the memory controller. This allows the R960 to maintain stability under sustained enterprise workloads without adding a heat spreader to the modules.

DDR5 4800 speed and voltage set the practical

The PC5-38400 rating fixes the maximum transfer rate at 4800 MT/s and the operating voltage at 1.10V. Higher frequencies or lower latencies are not supported by this kit, so the server will run at these JEDEC baseline specifications.

Questions about this item

Will the 1Rx8 ECC registered modules need replacement after the Dell PowerEdge R960 warranty period?

The modules are built with major OEM Samsung, Micron or Hynix chips and carry a lifetime replacement warranty from the manufacturer, so no scheduled replacement is required.

Does the CL40 latency at DDR5 4800 become the bottleneck during sustained compute workloads?

At 4800 MT/s with CL40 timing the memory controller hits its rated bandwidth ceiling first; latency stays constant and does not throttle throughput under continuous load.

How much heat and noise do the bare 288-pin RDIMMs add when the rack server runs all day?

Without heat spreaders the sticks rely on the R960's directed airflow; they draw 1.10 V at standard DDR5 power and add no audible noise of their own.
