Dell Vostro & XPS SO-DIMM upgrade

This 32 GB kit contains two 16 GB DDR4 2666 SO-DIMM modules built for select Dell Vostro and XPS laptops. The memory runs at 1.2 V with CL19 timings and is unbuffered, non-ECC silicon. It is designed to fill both SO-DIMM slots in the listed notebooks for a straightforward capacity increase.

Suits owners of the named Dell models wanting

The kit matches the 32 GB ceiling and two-slot layout documented for the Vostro 14 3491, Vostro 15 3590, Vostro 15 7590, XPS 15 7590 and XPS 15 9570. Buyers whose laptop has only one SO-DIMM socket, who require ECC error correction, or who need speeds above 2666 MT/s cannot use this kit.

32 GB dual-channel kit at DDR4 2666 CL19

The decisive specification is the 32 GB (2 × 16 GB) capacity running at DDR4 2666 with CL19 latency on 260-pin SO-DIMMs. If the target notebook supports this exact speed, voltage and maximum capacity, the kit will operate at the rated 2666 MT/s; otherwise the system will downclock all installed memory to the lowest common speed.

Questions about this item

Does the kit include both 16 GB modules or do I need to buy a second stick separately?

The package contains two 16 GB SODIMM modules giving 32 GB total, so no additional sticks are required.

Should I choose the 2666 MHz CL19 version or a different speed for my Dell XPS 15 9570?

This kit is validated for the XPS 15 9570 at DDR4 2666 CL19; selecting a different speed would not match the qualified specification.

Will the 2666 MHz rating actually run at that speed once installed in a Vostro 15 7590?

The modules operate at DDR4 2666 (PC4 21300) provided the processor and BIOS support that frequency; otherwise they run at the highest speed the platform allows.
