Dell Precision 7820 memory kit

This 512GB kit contains eight 64GB DDR4 2933 ECC registered DIMMs built for the Dell Precision 7820 tower workstation. It targets professionals who need maximum registered memory capacity for virtualisation, simulation or large dataset workloads.

Compatibility checklist

Verify that your Precision 7820 supports 4Rx4 registered modules at 2933 MT/s and that all eight 288-pin slots are free for a full population. Confirm the system BIOS is current and that the memory configuration rules for this workstation allow eight 64GB ranks.

Thermals and power

Each module operates at 1.2V without a heat spreader, relying on the workstation's directed airflow for cooling. Registered buffering adds minimal latency while keeping signal integrity stable under sustained server-class loads.
