NEMIX RAM 64GB (2x32GB) DDR4 2666 PC4-21300 CL19 UDIMM Dell Precision 3930 Rack memory upgrade

Dell Precision 3930 Rack memory kit

This 64 GB kit supplies two 32 GB DDR4 2666 UDIMMs built for the Dell Precision 3930 Rack workstation. It targets IT professionals and power users who need maximum capacity in that specific platform without registered or ECC modules. The unbuffered design keeps latency low for standard desktop workloads. Buyers requiring ECC error correction or registered signal buffering must look elsewhere.

Thermals and power profile

Each module runs at the standard 1.2 V DDR4 voltage, so power draw stays within typical unbuffered limits for 2666 MT/s operation. No heat spreader is fitted, relying on chassis airflow to keep the Samsung, Micron or Hynix ICs cool under sustained load. Noise is unaffected because the sticks add no active cooling. Systems with restricted airflow should verify case ventilation before installing a full four-module population.

Package contents and practical impact

The box delivers exactly two 288-pin 2Rx8 UDIMMs totalling 64 GB, ready for immediate installation in the validated Dell workstation. No software, drivers or configuration utilities are included or required; the memory is detected automatically at POST. The lifetime replacement warranty backs the modules against defects. Users needing capacities beyond 64 GB or speeds above 2666 MT/s will need a different platform or qualified kit.
