I have a question about these mobos; they are rated to 1333 but it says 1600 O.C. my question: does that apply to just dual channel or can i O.C. all 4 memory sticks that high? Reason im asking is bc i have seen other mobos that only allow you to run 2 memory sticks at higher speeds. If i had to choose id rather use 1333 quad channel vs 1600 in dual channel mode.
