768GB DDR5 ECC RDIMM kit for Dell Precision 7960

This 12-module kit delivers 768GB of DDR5 4800 registered ECC memory in a 2Rx4 configuration. It is built for Dell Precision 7960 rack and tower workstations that require high-capacity server RAM. Each 64GB module runs at 1.10V with CL40 latency and uses 288-pin RDIMM form factor.

Sustained load behaviour with registered ECC DDR5

Registered buffering reduces electrical load on the memory controller during continuous operation, helping stability in multi-threaded server workloads. ECC corrects single-bit errors on the fly, preventing data corruption over long runs. The 2Rx4 organisation supports high density across all twelve slots without exceeding standard voltage.

Build quality and daily implications

Modules are assembled with major OEM Samsung, Micron or Hynix components and carry no heat spreader, relying on chassis airflow for cooling. The 288-pin RDIMM keying matches Dell Precision 7960 DIMM slots exactly. Buyers who need non-ECC memory or a different pin count should look elsewhere.

Questions about this item

How much power do the 12 DDR5 4800 CL40 2Rx4 modules draw at the rated 1.10V when the Dell Precision 7960 runs continuously?

Each 64 GB RDIMM operates at 1.10 V, the standard voltage for DDR5 4800 registered ECC memory, so total power scales with the 12-module population.

What motherboard slots and CPU memory channels are required to install all 12 modules in a Dell Precision 7960?

The kit needs 12 free 288-pin DDR5 RDIMM slots wired to the processor memory channels; the workstation must support 768 GB of registered ECC capacity.

Will the CL40 2Rx4 registered ECC modules work in the same Dell Precision 7960 that currently has factory DDR5 RDIMMs installed?

Yes, provided the empty slots accept registered ECC DDR5 4800 2Rx4 RDIMMs; the system will run all modules at the lowest common speed and timing.
