I just love when people ask that question after buying the product in question instead of before.

But to answer your question, put that baby in and push it as high as it will go. There are crappy memory brands that will make sticks that do really well once in a while so you never know.
Edit: If you are not planning on overclocking and will stay below 166fsb then you should have no problems since you have a lifetime warranty, unless the company suddenly goes out of business.
