Summary: I liked this RAM at first, but then I started to get blue screens with memory failures. I work in IT and I know what I'm doing, and I know I have the right memory for my laptop. My Ultrabook only holds one stick, and MemTest fails every time. So now I have to go through the trouble of returning it to the manufacturer and getting a replacement. Oh well.
Summary: Works flawlessly with my new Dell Inspiron 17R SE 7720, which the morons at Dell sold as only "supporting" a 8GB RAM maximum, HAHA MY ASS...currently has 12GB now with this new module and plan to eventually upgrade to the 16GB "maximum," NOW THAT'S MORE LIKE IT!!!
Summary: Kingston has always been reliable in my dealings. I've purchase ram from kingston for over 10 years and I have no received nothing less than excellent performance and reliability from their products. I'm very satisfied with my purchase. I have a macbook pro intel core i7, 2.3ghz, 12GB of Ram (including new install of 8gb of ram from kingston).
