Dell Precision 7820 memory kit

This 384 GB kit delivers six 64 GB DDR4 2933 registered DIMMs built for the Dell Precision 7820 tower workstation. It targets professionals who need maximum ECC capacity for large datasets, virtualization or rendering workloads on that specific platform.

Capacity and headroom

The six modules populate every slot with 4Rx4 organisation, giving 384 GB of error-correcting registered memory at CL21 latency. Workloads that exceed this total will require a platform change because the kit already fills the workstation's supported configuration.

Thermals noise and power draw

Modules run at 1.2 V without heat spreaders, relying on the chassis airflow of the Precision 7820 for cooling. Registered buffering adds minimal electrical load while the ECC circuitry operates within standard DDR4 power limits during sustained server-class operation.

Questions about this item

Will the six 2933 MT/s DDR4 ECC RDIMM modules in this kit work with the Dell Precision 7820's existing memory slots?

The kit provides six 288-pin DDR4 RDIMM modules rated at 2933 MT/s (PC4-23400) with CL21 timing and 1.2 V operation, matching the Precision 7820's supported memory specifications for registered ECC memory.

How can I verify the 384 GB ECC RDIMM kit is detected and running with error correction enabled after installation?

Enter the system BIOS or UEFI on boot and confirm all six 64 GB modules appear at 2933 MT/s with ECC status shown as active; operating-system tools such as dmidecode or Windows Task Manager will also report 384 GB of registered ECC memory.

What exactly ships in the box and are any extra parts needed to install the kit in a Precision 7820?

The package contains the six 64 GB DDR4 2933 ECC RDIMM modules only; no heat spreaders, cables, brackets or additional hardware are included or required for installation in the workstation's memory slots.
