Dell Precision 3930 Rack memory kit

This 16GB kit contains two 8GB DDR4 2666 ECC unbuffered UDIMMs built for the Dell Precision 3930 Rack workstation. It targets IT professionals and builders who need validated, error-correcting memory for mission-critical workloads on that specific platform.

Simple user installation with manual reference

Modules slot into the 288-pin DDR4 sockets without tools; the supplier notes a typical upgrade takes minutes when following the system owner's manual. Common issues arise if the workstation BIOS is outdated or if mixed-rank modules are added alongside this 1Rx8 kit, which can prevent the system from posting.

Verify workstation model and memory configuration

Confirm the exact model is a Dell Precision 3930 Rack before ordering, as this kit is qualified only for that system. Check the current memory population and maximum supported capacity in the service manual to ensure the two 8GB modules match the available slots and rank limits.

Questions about this item

How can I verify the kit is running at 2666 MHz with CL19 after installing it in the Precision 3930 Rack?

Open Task Manager or BIOS and confirm the memory speed reads 2666 MHz and CAS latency shows 19; the modules operate at 1.2 V so no voltage change is needed.

What exactly ships in the box and do I need any extra brackets or cables?

The kit includes two 8 GB DDR4 288-pin ECC UDIMM sticks; no heat spreaders, brackets, cables or tools are included or required for installation.

Should I choose this 2666 MHz CL19 kit or the 2400 MHz CL19 version listed in the package details?

Select the 2666 MHz kit to match the Precision 3930 Rack's native memory speed; the 2400 MHz entry appears to be a specification discrepancy.
