Dell Vostro compatible 16GB DDR4 module

This 16GB DDR4 2666MHz CL19 UDIMM is built for Dell Vostro 3070 3470 3471 3670 and 3671 desktops. It runs at 1.2V with a 288-pin unbuffered non-ECC layout. The module meets JEDEC specifications and is backward compatible with 2133MHz and 2400MHz systems.

Suits owners of listed Vostro towers needing more

Builders who need ECC error correction or registered buffering should look elsewhere. Systems that only accept SO-DIMM laptop memory cannot use this desktop form factor. Buyers with motherboards limited to lower maximum capacity per slot should verify their board documentation first.

No bundled accessories or software included

The upgrade consists of the memory module alone. Installation relies on the system's existing DIMM slots and standard BIOS detection. No additional cables, tools or configuration utilities are supplied in the package.

Questions about this item

Does this module require an empty 288-pin DDR4 UDIMM slot on my Dell Vostro 3670?

Yes, it installs into any free 288-pin DDR4 UDIMM slot on the listed Vostro models.

Will the 2666MHz CL19 timing downclock automatically if my system currently runs 2400MHz memory?

The module is backward compatible with 2133MHz and 2400MHz speeds and will run at the slower speed.

How can I verify the 16GB capacity and 2666MHz speed are recognised after installation?

Check the BIOS memory summary or Windows Task Manager; both should show 16GB at 2666MHz.
