Samsung 32GB DDR4 2666MHz RAM Memory Module for Laptop Computers (260 Pin SODIMM, 1.2V) M471A4G43MB1

Wow! The Dell XPS 15 9550 is only specified by Dell to have a maximum of 32GB. But some reviews here on Amazon and forums elsewhere convinced me to give this module a try. Replacement was easy (remember to temporarily disconnect the battery first before swapping RAM modules) and took under half an hour. I even left one of the original 8GB modules in Slot B to see what would happen. It all worked!!! My system now reports 40GB and is running my CAD programs easily. Im debating ordering a 2nd module for a total of 64GB but will wait and see if I really need it. Thanks, Samsung for a great product. Thanks, Amazon for QUICK delivery.

Received exactly at the specified date.

Ordered 4 sticks. One of which was Dead on Arrival. Beware for dead sticks.

I purchased four of these (Samsung 32GB DDR4 2666MHz RAM Memory) and installed them into my Lenovo P52 laptop. After watching many YouTube videos the installation was easy (<15 minutes). My computer now recogonizes the 128GB of RAM. My medical imaging software programs can now easily analyze the large 100GB files. This is the best price on the web.

fast!

Installed it in a Thinkpad P53. Worked as expected.

Exactly what I need
