Dell Precision 7960 Compatible Server Memory

This 768 GB kit contains six 128 GB DDR5 RDIMMs validated for Dell Precision 7960 rack and tower workstations. It targets enterprises and professionals who need maximum registered ECC capacity for virtualisation, large datasets or memory-bound compute workloads.

Registered ECC DDR5 Kit for Multi-Channel Population

Each module is a 288-pin registered DIMM with on-die ECC and a 4Rx4 organisation, allowing the platform's memory controller to address all six slots without signal integrity penalties. The kit frees administrators from mixing part numbers and ensures matched latency and voltage across every channel.

Sustained Operation at 4800 MT/s and 1.1 V

Rated at DDR5 4800 (PC5-38400) with CL40 timing, the modules maintain rated throughput under continuous server loads while drawing 1.1 V. Registered buffering and ECC correction keep data integrity stable during extended render, simulation or database sessions without throttling.

Questions about this item

Does the 4Rx4 organisation on six 128 GB modules hit the platform’s rank-per-channel limit first?

Each module is a 4Rx4 registered DDR5 DIMM; the Dell Precision 7960 workstation defines the rank-per-channel ceiling for this configuration.

How much heat and power should I expect from a 768 GB kit running continuously?

The modules operate at 1.10 V with no heat spreaders; total power draw and thermal output depend on the workstation’s memory-subsystem design and airflow.

What motherboard feature must already be present for this ECC registered kit to function?

The system must provide DDR5 RDIMM slots with ECC and registered-buffer support, as used in the Dell Precision 7960 rack or tower workstation.
