My issue is that my cpu does 2.7 stable at 1.1875v, but it takes 1.325 for 2.75 to be stable. There's got to be something else going on to cause the cpu to need that much more voltage. And I actually do get 6.6ns at either 2.5 or 2.75 nb with the cpu at 2.75, my mistake. But the L3 does get faster with increased memory speed, I think I meant to say that the difference between the 400 and the 533 mem dividers gave me the difference in latency rather than the nb speed.
