no, thats about what the stock levels are. you can safely go to 1.5v. 1.525 max if your cooling can support the temps.

Actually the max limit you would want is 1.7 (as told by Taeric). I have my Pentium 4 running at 1.57volts.

1.7 volts works just fine with Northwoods, but you don't want to exceed 1.525 volts on Prescotts unless you have really good cooling.

1.325-1.385v is the standard voltage for a processor built on the Prescott core of the Netburst architecture

As long as your load temperature stays under 55C, you're in good shape. With good temps, you still have another 0.1 volts, which can make a big difference.

It is best to start a new thread for questions

As for your answer at that voltage there is a possibility that it will operate, however I would expect the voltage to be nearer to 1.7v for it to be totally stable. Run Prime95 to check that it is fully stable

it crashed anyway after 7 mins.....and prime95...i dld it now

I got from 2.66Ghz to 3.5 with stock voltage but even at 3.3Ghz i had to add a little vcore for it to be stable, its now running like stock (but faster )
