I need to good quick app to complete stress out my new cpu. I used prime95 which is passed. But that did not seem full use all cores I am tiring to fine tune the voltage. I set cpu to speed of 6600e(my old cpu) which was 355 X 9 which on that box had ran it with voltage overage .125. When I first got the 6600q set to 355 x9 at .050 it would boot. So I set the volatge to .125. I have since backed it down to .1. Have done some gaming benchmarking and it is stable ut 3 frame rates went from 102 to 250. LIke said I would like app that complete stress all four cores out. That something like prime 95.
