Rating: 5/5 fast delivery, good price and quality. August 19, 2013 I have Samsung Laptop with 4GB of Ram and I bought this 4GB to fill in the empty slot and now I’m powered with 8GB of Ram. It’s better to have both Ram with the same brand and speed clock for best compatibility.

Rating: 5/5 Customer For Life April 2, 2012 I am and have been a loyal Samsung memory consumer since my early days working on Macs. I've used Samsung and Micron exclusively now for over a decade after first trying out, and being dissatisfied with cheaper, rebranded modules (like Crucial). My experience with Samsung has been consistent. It's a quality that you can count on. When you run a small business while working a very demanding full time job and raising a family, you simply don't have time to waste returning defective products. Warranties are great. Reliability is better.

I would recommend this item to a friend!

Rating: 5/5 Just what The iMac Needed March 10, 2012 The iMac was in need of some memory and upon countless internet forums recommending OWC I ordered. Delivery was fast and the iMac runs like it should now with 12gb of ram. Flawless. A friend of mine has 8gb which is what anybody with a iMac should at the very least have! Thanks OWC

Rating: 5/5 As advertised. February 16, 2012 Once the package arrived, I just slapped the 2x4 GB sticks into my late 2011 MPB 15" 2.4 GHz i7 and away we go. Smooth sailing as expected. I decided to go with Samsung originals just for the piece of mind.
