Dell Precision 7920 Workstation Kit

This 768GB kit supplies twelve 64GB DDR4-2933 registered ECC modules built for the Dell Precision 7920 rack or tower workstation. It targets IT teams and power users who need maximum memory capacity for virtualization, large datasets or rendering workloads on this specific platform.

768GB Registered ECC Headroom

The twelve 4Rx4 modules deliver 768GB at 2933MHz CL21 running at 1.20V, filling all available slots on the Precision 7920. Registered buffering and ECC protect data integrity under sustained load, while the quad-rank density reaches the platform’s supported ceiling without headroom for further expansion.

12-Module Matched Kit

The package contains twelve matched 288-pin RDIMMs tested together for compatibility with the Dell Precision 7920. No heat spreaders are included, relying on the workstation’s chassis airflow. Buyers needing fewer modules or non-ECC memory for other platforms cannot use this configuration.

Questions about this item

Will these 2933 MHz CL21 4Rx4 ECC RDIMM modules run alongside slower DDR4 sticks I already have in the Dell Precision 7920?

The system will clock all installed DDR4 modules down to the speed of the slowest kit, so existing slower memory will limit the 2933 MHz rating of these 12 modules.

How can I verify the 768 GB kit is detected correctly after installing the twelve 64 GB RDIMMs?

Open the BIOS or UEFI on the Precision 7920 and confirm that all 12 slots show 64 GB each at 2933 MHz with ECC registered status.

Does the package include anything besides the twelve 288-pin DDR4 RDIMM modules?

The box contains only the 12 x 64 GB DDR4 2933 MHz CL21 4Rx4 ECC registered RDIMMs; no cables, brackets or additional accessories are supplied.
