Crucial Ballistix Finned DDR3 1866 MHz CL9 4 GB
 

The Crucial Ballistix Finned memory does not only look cool, but they also pack an on-board sensor so that you can actually make sure they stay cool during use and extreme overclocking. We take the 1866 MHz kit for a spin to check if it manages to make an impression or barely ding our armor.
