uh, the it has been my experience that the ram has to either be dual channel or not, as far as the colored slots, that is the pairing on my mobo, I have 2 blue slots and 1 black one, when I had a single stick it was in the black one, when I got a second, I pulled the one, and put them both in the blue slots...
worst case scenario from what I can see it just wouldn't read the ram if it is not in the correct slot, so it won't boot... if it boots up fine it should be ok
