NEMIX RAM MD21300-618K2 32GB DDR4 2666 CL19 memory upgrade

Dell Precision 3930 Rack Workstation Compatible

This 32GB kit contains two 16GB DDR4 2666 UDIMM modules built for the Dell Precision 3930 Rack Workstation. It targets IT professionals and power users who need to expand system memory for virtualisation, content creation or heavy multitasking. The unbuffered non-ECC design matches the workstation's standard memory architecture.

Check Your Current Configuration

Before ordering, verify that your Precision 3930 Rack Workstation has two free 288-pin DIMM slots and that the motherboard firmware supports DDR4 2666 at 1.2V. Confirm the existing modules are also non-ECC unbuffered UDIMMs running at CL19 so the new pair will operate in dual-channel mode without timing mismatches.

Kit Contents and Testing Impact

The package delivers a matched pair of 1Rx8 modules stress-tested under load for stability. No heat spreaders are included, so airflow inside the rack chassis must be adequate for bare PCBs. The lifetime replacement warranty covers the modules themselves, while the pre-validated compatibility removes the guesswork from the upgrade process.
