Dell Precision 7960 memory kit

This 256GB DDR5 ECC registered RDIMM kit contains four 64GB modules built for Dell Precision 7960 rack and tower workstations. It targets professionals who need maximum memory capacity for large datasets, virtualization or rendering workloads. The modules are new and validated for the specified platforms. ||

DDR5 4800 CL40 registered ECC

The decisive specification is DDR5 4800 with CL40 latency, 1.10V operation and 2Rx4 registered ECC organisation. These parameters must match the workstation memory controller and BIOS settings for the system to post and run without errors. Mismatched speed, rank or ECC type will prevent boot. ||

256GB capacity for heavy workloads

Four 64GB modules fill all available slots on many Precision 7960 configurations, delivering 256GB of addressable memory. This headroom handles multi-VM hosts, in-memory databases and complex simulation jobs. Workloads that exceed 256GB or require faster than 4800 MT/s will need a different platform.

Questions about this item

What does the 4800 MT/s speed mean once the four 64 GB modules are installed in a Dell Precision 7960?

The kit runs at DDR5 4800 (PC5-38400) with CL40 latency, giving the workstation 256 GB of registered ECC memory at the platform's rated transfer rate.

How does the 288-pin DDR5 RDIMM interface and registered design affect what the system can use?

The 288-pin DDR5 RDIMM form factor with registered buffering and on-die ECC is required by the Precision 7960; unbuffered or non-ECC modules will not work.

What physical clearance does the 2Rx4 64 GB module need inside the Precision 7960 chassis?

Each stick is a standard-height 288-pin DDR5 RDIMM without a heat spreader, so it fits the factory DIMM slots in both the rack and tower versions of the 7960.
