The bottom line on the Crucial Ballistix Tracer 4GB DDR3-1333 memory kit is that it offers great performance right out of the box, and for those looking for more, they will gladly oblige. While they may not have the highest stock speed rating, even a novice overclocker should be able to get a few hundred extra MHz out of this kit.
