Dell Precision 7820 256GB Kit

This 256GB kit contains eight 32GB DDR4 2933 ECC RDIMM modules built for the Dell Precision 7820 tower workstation. It targets IT professionals and engineers who need maximum registered memory capacity for virtualization, rendering or large dataset workloads.

Installation and Common Issues

Modules are keyed 288-pin RDIMMs that seat in the workstation's DIMM slots without tools; the owner's manual details the required population order for eight modules. The most frequent issue is mixing registered and unbuffered DIMMs or skipping the prescribed slot sequence, which prevents the system from posting.

Sustained Load Behaviour

ECC circuitry corrects single-bit errors in real time while the registered buffer reduces electrical loading on the memory controller during continuous multi-threaded jobs. The 1.2V operating voltage and major OEM DRAM chips maintain stable throughput across extended compile, simulation or database sessions.

Questions about this item

How can I verify the NEMIX RAM 256GB kit is running at the rated DDR4 2933 speed and CL21 latency after installation?

Enter the system BIOS or UEFI on the Dell Precision 7820 and confirm the memory frequency shows 2933 MT/s with CAS latency 21; the registered ECC modules will also report their 2Rx8 organisation and 1.2 V voltage in the same screen.

What exactly ships with the MR23400-328K8 part number and do I need any extra brackets or cables for the Precision 7820?

The box contains eight 32 GB DDR4 2933 ECC RDIMM modules (256 GB total) — no heat spreaders, brackets, cables or tools are included or required for the tower workstation's DIMM slots.

Why choose the 256 GB (8 x 32 GB) configuration instead of a smaller kit for the Precision 7820?

This kit fills all eight channels with 32 GB 2Rx8 registered DIMMs, delivering the maximum supported capacity at the platform's native 2933 MT/s speed while maintaining ECC integrity for mission-critical workloads.
