Capacity and fit

This NEMIX RAM kit delivers 128 GB across eight 16 GB modules for the Dell Precision 5820 tower workstation. Registered ECC DDR4 RDIMMs provide error correction and signal integrity required by the platform. The kit is new and built with major OEM chips from Samsung, Micron or Hynix.

Suitable builds and limits

The memory suits owners of a Precision 5820 who need the maximum 128 GB capacity in a fully populated configuration. Buyers whose workstation uses a different Dell model or a non-ECC platform should look elsewhere because this kit is validated only for the specified system.

Deciding specification

The registered ECC RDIMM design with CL21 timing at 2933 MT/s is the single factor that determines compatibility. Only systems that require registered ECC DDR4 RDIMMs at this speed and latency will accept the kit.

Questions about this item

Should I choose the 8×16 GB kit or a different capacity for my Dell Precision 5820?

The 8×16 GB kit provides 128 GB total and fills eight DDR4 slots. If your workload needs less memory, a smaller kit with fewer modules may be more cost‑effective.

What does the 2933 MHz speed mean once the modules are installed in the Precision 5820?

The DDR4‑2933 (PC4‑23400) rating is the maximum data rate the modules support. Actual speed will match the highest rate the workstation’s memory controller and BIOS allow, up to 2933 MHz.

How does the 288‑pin RDIMM interface affect compatibility and performance?

The 288‑pin DDR4 RDIMM form factor fits registered DIMM slots in the Precision 5820. ECC and registered buffering add error correction and signal integrity for stable server‑class operation.
