Amen brother! i am afraid to really start getting in depth with my responses because simply trying to help brings about those type of responses in this and other threads I've had the good fortune to see. Kingston website shows single channel, double channel, and triple channel RAM at 1800 AND 1866 speeds. Asus Sabertooth shows a triple channel x58 mobo and a double channel p67. There are so many variations just right there with how things could be setup that we cannot help anyway without knowing more. but whats the difference anyway right? Computers---It's like a noodle with a bit too much sauce in it which dont even make a big diffrent... /feed a man a fish vs. teach him to fish
