i'm currently using 3x2gb Corsairs Dominator on triple channel on an Asus rampage II extreme. I was wondering if i could install another 3 sticks of OCZ XMP Ready Series, making my system 12gb. Is there a down side to putting extra memory on the non-triple channel slots and mixing corsairs with ocz. The timing is the same, both marked at 8-8-8-24. Also would i even notice an improvement on my system with 12gb ram.
