What Mother board are you going to be using?
If its an Asus (especially P4C800 Deluxe) you may want to head to corsair's forums
Their Compatability forum:

and do some looking around. There are conflicts with the low latency and the Asus MB Bios. You will have to update the Bios just to gain stability, and still won't be able to use the low latency (2-2-2). Same with Hyper X. I'm using Kingston's Value Ram 3-3-3, because I have the P4C800 Deluxe MB and I didnt see the point in paying more for low latency that I cannot use. Your latency setting will end up something like 3-3-3-8.
Just a Thought.
