Crucial Ballistix 4GB DDR3-1866 BL2KIT25664FN1869 Review
 

Out of the box the Ballistix BL2KIT25664FN1869 kit offers great
performance that should satisfy just about anyone. If this isn't enough
these Ballistix sticks offer a decent overclock while keeping the stock
timings. Crucial has also put thermal sensors in these sticks so that
you can monitor the temperatures with their Ballistix MOD Utility
should you really want to push the limits.
