Dell Precision 7920 memory kit

This 384GB kit contains six 64GB DDR4 2933 modules built for the Dell Precision 7920 Rack or Tower workstation. The registered ECC design targets servers and workstations that need error correction and signal stability under sustained loads. IT professionals handling virtualization, rendering or large datasets gain the capacity headroom this configuration provides.

Compatibility and slot check

Verify the workstation accepts DDR4 2933 registered RDIMMs and has at least six free 288-pin slots before ordering. The modules run at 1.2V with a CL21 latency and a 4Rx4 organisation, so the memory controller and BIOS must support that rank density. Consult the Dell Precision 7920 manual for the approved population order and maximum supported capacity per channel.

Installed characteristics

The kit ships as six matched modules without heat spreaders, relying on the chassis airflow of the Precision 7920 for cooling. Registered buffering and ECC functionality are active once seated in supported slots, delivering the data integrity required for mission-critical workloads. No additional software or configuration utilities are included in the package.

Questions about this item

What does the kit contain and is anything else needed to install it in a Dell Precision 7920?

The kit contains six 64 GB DDR4 2933 ECC registered DIMMs for a total of 384 GB. No extra parts are required; the modules fit directly into the 288-pin RDIMM slots of the workstation.

Why is this 384 GB kit the right choice instead of a smaller or larger capacity?

The Dell Precision 7920 supports up to 384 GB using six 64 GB 4Rx4 modules at 2933 MT/s. This kit matches that maximum supported configuration exactly.

What does the 2933 MT/s rating mean for actual workload performance?

The modules run at 2933 MT/s with CL21 latency at 1.20 V, delivering the peak bandwidth the 7920 memory controller is designed for in memory-intensive tasks.
