Dell Precision 7920 512GB DDR4 kit

This 512GB kit contains sixteen 32GB DDR4 2933MHz registered ECC RDIMMs validated for the Dell Precision 7920 rack or tower workstation. It targets IT teams and power users who need maximum supported memory capacity for virtualisation, large datasets or rendering workloads.

Capacity and headroom at 2933MHz CL21

The 512GB total fills every slot on compatible Precision 7920 configurations, giving headroom for hundreds of virtual machines or in-memory databases. Performance scales until the memory controller or CPU thread count becomes the bottleneck, not the module speed or latency.

Upgrading from smaller RDIMM sets

Replacing a partial population of lower-capacity RDIMMs with this full 16-module kit removes the need to mix ranks and speeds, simplifying qualification. The jump is worth it when workloads exceed the current installed capacity or when ECC error correction becomes mandatory for data integrity.

Questions about this item

Will the 16 modules of DDR4 2933 RDIMM work alongside any existing ECC memory already installed in my Precision 7920?

The kit provides 16 matched 32 GB modules rated at DDR4 2933 CL21 1.2 V 2Rx8; mixing with other modules is possible only if they share the same speed, voltage, rank and ECC registered specification.

How can I confirm the full 512 GB kit is recognised and running at 2933 MHz after installation?

Enter the system BIOS or UEFI and verify the memory summary shows 512 GB total, DDR4 2933 MT/s, CL21 timings and ECC active for all 16 slots.

Does the package contain anything besides the 16 RDIMM modules, or must I purchase heatsinks or cables separately?

The box includes only the 16 x 32 GB DDR4 2933 CL21 1.2 V 288-pin ECC RDIMM modules; no heat spreaders, cables or additional hardware are supplied or required.
