Pros: This stuff is great, it's quick, reliable, and CHEAP! Bought two sticks of this to add to my existing one, and noticed a major performance increase. I will buy another when I have the money.

Cons: For some reason the default timing on these are set higher than the 4-4-4-12 timing it says in the manufacturer specs. To set the timing to 4-4-4-12 I had to go into my Bios and manually change it. No big deal though.

Overall Review: I highly recommend this stuff, just check your Bios to make sure you are getting the 4-4-4-12 timing!
