Dell Precision 7820 ECC RDIMM kit

This 128GB kit provides two 64GB DDR4 2933MHz registered DIMMs built for the Dell Precision 7820 Tower workstation. ECC and registered operation protect data integrity in professional workloads. The modules run at 1.20V with CL21 latency. They are validated for compatibility with the specified Dell platform.

Capacity and headroom for server tasks

Two 64GB modules deliver 128GB total capacity for large datasets, virtualization and multi-application workflows. Four-rank 4Rx4 organisation increases density per channel. Registered buffering reduces electrical load on the memory controller. The kit suits workloads that need maximum supported memory per slot.

DDR4 2933 registered interface limits

DDR4 2933 (PC4-23400) sets the peak transfer rate for this registered ECC design. Registered signalling adds one clock cycle of latency versus unbuffered modules. 288-pin RDIMM form factor fits only DDR4 RDIMM slots. Systems requiring unbuffered or non-ECC memory cannot use this kit.

Questions about this item

Will the 2933MHz DDR4 ECC RDIMM modules run at full speed alongside slower DDR4 DIMMs I already have in the Precision 7820?

The system will clock all installed memory down to the speed of the slowest module present, so existing slower DDR4 DIMMs will limit these 2933MHz kits to that lower frequency.

How can I confirm the 128GB kit is operating as registered ECC memory after installation?

Enter the system BIOS or UEFI on boot and verify the total capacity shows 128GB, the speed reads 2933MHz, and the memory mode reports ECC Registered active.

Does the 2x64GB package include a heat spreader or any installation tools I need to buy separately?

The modules ship without a heat spreader and no tools are included; only the two 288-pin RDIMM sticks are in the box.
