Dell Precision 7820 compatible kit

This 384GB kit contains twelve 32GB DDR4 2933MHz registered ECC RDIMMs built for the Dell Precision 7820 Tower Workstation. Modules run at 1.2V with CL21 latency and a 2Rx8 organisation across 288 pins.

Suited for memory-intensive workstations

The registered ECC design targets Dell Precision 7820 users who need maximum capacity for virtualisation, rendering or large datasets. Builders using consumer motherboards or non-Dell platforms should look elsewhere because the modules are validated for this specific system.

Steady throughput under sustained load

Rigorous stress testing under load is performed on every module to verify stability during extended compute sessions. Registered buffering and ECC correction maintain data integrity when all twelve slots are populated for long periods.

Questions about this item

What does my Dell Precision 7820 need to run this 384GB DDR4 2933MHz CL21 ECC RDIMM kit?

The workstation must support DDR4 2933MHz PC4-23400 registered ECC memory at 1.2V and have twelve free 288-pin RDIMM slots for the 12x32GB modules.

How will this 2933MHz CL21 kit behave if I keep slower DDR4 ECC RDIMMs already installed in the 7820?

All installed modules will run at the speed and timings of the slowest kit present, so the 2933MHz CL21 modules will down-clock to match the older modules.

After installing all twelve 32GB modules, how can I verify the full 384GB is recognised and running at 2933MHz with ECC active?

Check the BIOS memory summary or run a system information tool; it should show 384GB total, DDR4-2933 speed, CL21 latency and ECC enabled.
