It's still using a divider though, that particular motherboard just doesn't have a blatent section for like you said 1:1, 1:2 or whatever, mine has that and goes all the way to 6/6 mind you I'm on a socket A system, but yeah anyway, you set yours down to 166 and that's basically a 4/3 ratio I believe it is.....it's labeled different but it's still a divider,
but like I said, gaara and I got confused, because all we saw was "I set it at 166" and was like.........wtf!?! but yeah we got it now
