Dell PowerEdge R960 compatible kit

This 1 TB server memory kit contains eight 128 GB DDR5 RDIMM modules built for the Dell PowerEdge R960 platform. Registered ECC technology provides error correction and signal buffering required by multi-socket enterprise workloads.

Registered ECC RDIMM architecture

The registered design places a register between the DRAM and the memory controller, reducing electrical load on the server bus. On-die ECC detects and corrects single-bit errors to maintain data integrity in mission-critical applications.

DDR5 4800 speed with CL40 latency

Modules operate at DDR5 4800 MT/s (PC5 38400) with a CAS latency of 40 cycles at 1.1 V. This specific speed and latency combination determines whether the kit matches the R960 memory subsystem requirements.

Questions about this item

Will the 128GB modules need replacement if the server workload grows beyond 1TB?

The kit fills eight slots with 128GB modules for a total of 1TB. If the Dell PowerEdge R960 has more slots available, additional identical modules can be added later without replacing the existing ones.

Does the CL40 latency become the first bottleneck under sustained heavy loads?

CL40 is the rated CAS latency at DDR5 4800. Under sustained load the memory controller and the 4Rx4 rank organisation determine throughput before the latency figure itself becomes the limiting factor.

How much heat do the eight 1.10V modules produce when running all day?

Each module operates at 1.10V without a heat spreader. The registered DDR5 design and ECC circuitry keep power draw low, so the eight modules together add only modest heat to the server airflow.
