I am building an i7 rig and i am getting the ASUS P6T Deluxe V2 board. I have picked out two different thing of ram. One set http://www.newegg.com/Product/Prod [...] 6820227477 is 1600mhz but 1.65v and another http://www.newegg.com/Product/Prod [...] 6820145220 is 1333mhz and is only 1.5v seeing that I can only go up to 1.65v with the ram with core i7s which one would get me higher clocks? would increasing only the speed on the 1600mhz ram get me further then if i can increase the speed and the voltage of the 1333mhz...thanks...also if you have any input on my choice of board i am open to suggestions I chose this board because i can run 2x sli with 2 16x lanes and have a pcie soundcard in the top 4x slot.
