+1 on the above. Also keep in mind that if you buy RAM with those extreme fins on them you could have issues with clearance on an aftermarket air cooler like the Hyper 212. If you're only putting in two sticks, and your mobo lets you put them in the slots away from the cooler, you most likely won't have clearance issues. Even the Corsair Vengeance Low Profile sticks like I'm using, BARELY clear the bottom of the Hyper 212 if I use slots 1 and 3.
Good luck on your first build, and have fun!
