Just purchased an AMD 4400+ Brisbane 65nm

I probably won't see it till Wednesday or Thursday, but ahead of time I wanted to know. What is the highest voltage I can safely go on this proc?

I always remembered the 10% rule, but that was back in the days of 1.5-1.6V Vcores. 10% was a decent amount of extra voltage. Now with many 65nm procs running 1.2V and 45nm procs slated to run even less, how far can we push it? I see many people running their Core 2s at 1.475, which is far above the 10% line and reminiscent of the days of the 130nm P4s. So what is the limit now?

1.475 - 1.5 is my rule, anymore than that is too much without better than water cooling.

Brisbane CPUs should have a vid of 1.3v, so your top safe limit should be around 1.43v (1.425v realistically speaking).

Im was running 1.39vcore@38c to get 3.0 stable, 2900@ stock voltages 1.32v since dropped to 1.36 as i found the instabilities were due to ram timings @450+ changed divider
viola.mobo doesnt regulate vcore well at any other setting so cant go lower.actually doesnt change at all next 2 lower voltage settings.

I agree with most of this, considering we're only using a stock cooler, I doubt we'll be able to put more than 1.4V to it anyways.
