Is the Corsair Vengeance 2x4gb work the same without using dual channel ? are the dual channel 2x better than not using dual channel ? i cant use dual channel because the Cooler Master X6 cpu cooler. i bought this cooler just because it got promo from 299$ to only 99$ (My country money ofcourse Ringgit Malaysia) or just not using dual channel with 2x4gb vg ram still work fine ?
