Summary: Didn't blow me away, but didn't disappoint me either. Does exactly what it should. Last Corsair stick I had died on me after 1 year. It is a reputable brand, however, so I gave them another shot.
Pros: Setup was bing bang boom, cheap price on newegg, and passed memtest 86 upon installation.
Cons: Didn't come with unicorns and magical RAM fairies that guarantee the ram stick never to ever go bad ever.
Summary: This works perfect with ASUS s400ca. From the very moment after I click this memory chip into my laptop, I can feel the difference in speed. Mine had 4gb and now 8gb. With 4bg only, my laptop did not have enough free memory so had to read and write on the hard drive.
