Pros: The one stick that works was fine.

Cons: I consistently received blue screens with one stick (sounds like I'm not the first). I couldn't return the RAM because the day before the blue screens I had mailed in my UPC for a mail-in rebate, or believe me, I would have. I emailed Patriot and got an answer right away to double checking my system before I sent it in for an RMA. I sent 2 more emails and got no response. It's now been over a month. I called, and got sent to voice mail. Patriot can consider me no longer a customer.

Overall Review: Honestly, it's not worth the risk of having only half the RAM work. I bought 4 gigs of G.Skill and it works perfect. Too bad I wasted money on this product.
