Our take on the Dell Precision 5820 Memory RAM 16GB Kit (2x8GB) 1Rx8 DDR4 2666MHz (PC4-21300) RDIMM

This is a 16GB memory kit for the Dell Precision 5820 workstation, made of two 8GB DDR4 RDIMMs running at 2666MHz (PC4-21300). It is registered ECC server-style memory, single-rank (1Rx8), which is what the 5820's Xeon platform expects. It suits owners adding memory to a Precision 5820 for CAD, rendering or virtualization work. Buying matched pairs keeps the two modules identical, which matters on a workstation that runs memory in channels.

Questions and answers

Will this work in a Precision 5820?
Yes. It is a 16GB kit of two 8GB DDR4 RDIMMs at 2666MHz, which is the registered ECC memory the Precision 5820's Xeon platform uses.
Can I use this in a regular desktop PC?
No. RDIMM (registered) memory is for workstation and server platforms. Most consumer motherboards take unbuffered DIMMs and will not boot with this.
Is 16GB enough for CAD work?
It is a reasonable starting point for light to moderate CAD and office work. Heavy assemblies, rendering and virtual machines benefit from more, so check how many slots are free before buying.
Can I add this to the memory already in my 5820?
Usually yes if the existing modules match in speed, rank and registered type. Mixing different ranks or speeds can force lower settings or cause instability, so matched pairs are safer.
What is in the box?
Two 8GB DDR4 2666MHz single-rank RDIMM modules, for 16GB total.
