When AMD brought the Phenom 2 X4 lineup off the drawing board to E-Tailers, it brought with it DDR3 Dual Chanel memory. Of late, the focus has been on Triple channel memory but with Phenom 2 and Core i5 making its debut soon, DDR3 Dual channel is going to be back in the news quickly. To that end we obtained a Kingston HyperX DDR3 1600 4GB Dual Channel Kit to take a look at on the Phenom 2 Platform. We'll be running the HyperX through its paces and putting it against a single 4 GB kit of Crucial Ballistix that runs at 1333 to see if we get any performance gains from moving from 1333 to 1600MHz. Sometimes that little bit of extra speed can mean the difference between a snappy system and a system that seems to drag.
