Dell Precision 3930 Rack memory upgrade

This 16 GB DDR4 UDIMM is built for the Dell Precision 3930 Rack workstation. It installs as a single 288‑pin module and runs at 1.20 V without ECC or registration. The CL19 timing matches the platform’s 2666 MHz specification.

Suits owners expanding a Precision 3930 Rack

Builders who need ECC protection, registered modules, a different voltage or a higher density per slot should look elsewhere. Systems that require matched pairs or quad‑channel kits are also outside the intended use case.

The 1Rx8 single‑rank organisation decides fit

One rank of eight chips per side keeps the electrical load identical to the factory configuration. If the motherboard calls for dual‑rank or x4 organisation this module will not meet the requirement.

Questions about this item

Does the 288-pin DDR4 UDIMM fit the Dell Precision 3930 Rack motherboard slots?

Yes, the module uses the standard 288-pin DDR4 UDIMM form factor that matches the Precision 3930 Rack memory slots.

What is the correct orientation step when inserting the CL19 module into the slot?

Align the notch on the module edge connector with the key in the slot, press down evenly until both retention clips click into place.

Will the 1.20V non-ECC unbuffered module require any firmware updates or periodic replacement?

No firmware update is needed; the module runs at standard 1.20V and is designed to last the system lifetime without scheduled replacement.
