Ok so I really want to build an i7 system but being a poor College student it seems it might be a bit too expensive. So I thought why not just build a decent Q6600 system with a 790i and then upgrade toward the end of the year when i7 CPUs and MoBos are cheaper. So, in my ideal i7 setup I wanted to get a tripple channel Corsair DOMINATOR 3x2GB 1600 (PC 12800) kit. My question is, could I buy this RAM and then just use 2 of the DIMMs until I upgraded? The 790i supports DDR3 up to 2000MHz. However, I'm just not sure if, somewhere, there is something built into the RAM that says it needs to run on Triple Chanel. So what do you think, can I just use 2 of these DIMMs in my Q6600 setup until I upgrade to i7 or should I just buy seperate RAM for each setup. Basically I want as much of my hardware to convert to my i7 system so all I have to buy is a EVGA x58 Board and i7 920. Thanks for any help, peace.
