Dell Precision 5820 memory kit

This 128GB kit contains four 32GB DDR4 RDIMM modules built for the Dell Precision 5820 tower workstation. Registered ECC operation and a 2933 MT/s data rate deliver the stability required in professional environments. The modules run at 1.2V with CL21 latency and use a 2Rx8 organisation. No heat spreaders are fitted.

Workstations needing registered ECC memory

Suits IT professionals upgrading a Precision 5820 to its full 128GB capacity for virtualisation, rendering or large datasets. Builders using consumer motherboards, laptops or systems that require unbuffered non-ECC DIMMs cannot use this registered kit. Buyers who need a different capacity or speed should look at other system-specific kits.

Four modules fill every slot

The 4x32GB configuration occupies all four memory channels on the Precision 5820, providing maximum bandwidth for memory-intensive workloads. Registered buffering and ECC protect data integrity during sustained compute tasks. Systems limited to lower densities or unbuffered memory will not accept these modules.

Questions about this item

Will this 288-pin DDR4 kit install in a Dell Precision 5820 tower workstation?

Yes, the kit is built specifically for the Dell Precision 5820 and uses the 288-pin DDR4 RDIMM form factor required by that system.

Can I mix these 2933 MHz registered ECC modules with existing non-ECC UDIMMs in the same machine?

No, registered ECC RDIMMs cannot be combined with unbuffered non-ECC UDIMMs; the memory controller requires matching module types across all populated slots.

How do I confirm the system recognises all 128 GB at 2933 MHz after installation?

Enter the BIOS or UEFI setup on boot and verify the memory summary shows 128 GB total capacity running at 2933 MT/s with ECC active.
