really dissapointed..
It is a voltage issue. Your Q6600 is sucking more power than any of your other chips. If you run the same tests under stock conditions, you wouldn't have that problem. I am currently trying to swap my PSU for the exact same reason.

By the way, P95 small ffts is much more demanding on CPU than any of those apps you listed, except maybe OCCT, with slider adjusted all the way to the left.

Pumping as much as 1.6v to a q6600 is probably bothering on 165watts! Not many 3.3 rails can sustain than in addition to rams, nb, sb, and so on and so forth. But if you believe your hardware is up to the task, then you may consider finding the right combination settings as that could also be the culprit. My vote is on voltage though.
