Ok, so I tried staying with the whole number thing for a while and it got my rig to run no more than 2.55ghz at best.Then,I went from a 10x to a 9.5x---and voila!! I can now run my rig at 2.675ghz stable with a high clock of 2.74ghz.!! So, for me anyway, it has worked out--although it may not for others.
