Review on Samsung 16GB DDR4 PC4-21300 Laptop RAM Memory Module: 2666MHZ, 260 PIN SODIMM, 1.2V, CL 19 - Ultra-Fast and Efficient Performance by Marc Farrell

The package is really strange. It's like having to fight to get the card. Maybe some bumpers so you can remove it EASY. I installed it in 15 minutes. My computer recognized the card, I plugged it into the existing 16 4 pin connector I already had in my laptop as I had a different slot why not. I am very happy that I now have 32 RAM and can run multiple apps on my 2TB SDD (which I will NEVER use fully) like Second Life, Music, Photos, which load quickly with no lag.
