Pros: Fits into the ram slots.

Cons: I purchased two of these sticks and the both were faulty. The first stick I had on my desk for about 2 months before I remembered to install it. Once installed, it would not allow my computer to boot. Ran memtest and froze. It was beyond the initial 30 days, so now I can't return it and I'm stuck with a dead stick. Stick number 2 arrived today, DOA again. I ordered the second thinking the original problem was just a fluke, but it seems from my experience and from the many others in these reviews, Newegg has a bad batch of Corsair sticks. There are probably ones that are not having problems, but I'm not going to experiment with another stick.
