I/O voltage OC risks?

[turtle219]

i have a msi pro2-a and i am running at 600@~990 but its only stable (not perfect but good enough) if i increase 3.3 I/O voltage to 3.45
i just wanted to ask what are the risks to my components? i kno increasing beyond specifications always runs a risk but does anyone have actual bad experiences with I/O voltage tweaking? don't want to greatly risk my ram or anything...

tried so much to get 1 GHZ, so close, but its rock solid at 936, can't be that much of a difference, just wanna OC enough to get the best out of my components
thanks

i have a bx133 raid and teh default voltage is 3.5v

I know with my Abit BE6-II MB, when I set my I/0 to run at 3.3v, that is not necessarily the exact voltage that my components are getting. Using MB Monitor or Abit HW Doctor, these programs report that the I/O voltage that my components are getting is only 3.23v. So I have bumped it up to 3.4v so that they are getting exactly (as far as I can tell) 3.3v

So have you checked using some type of HW monitor what I/O voltage you are getting? You may not be getting enough juice.

But to answer your question, I don't think that raising the voltage up to around 3.5-3.6v is bad. I would not push it any further than that, but I do not know for a fact what the highest voltage should be.

My MB is like Shiznuts in the fact that the default voltage is 3.5v. And I ran at this voltage for a while before I discovered the above, and lowered it to 3.4v. It is supposedly true that raising the I/O voltage MAY help with stability and reaching higher speeds, but raising this voltage has never helped me in my O/C adventures.

It's actually required to raise it that high to get somethings to work right. My old roomate had a Geforce DDR that would throw artifacts all over the screen at 3.3v I/O, but would run fine at 3.5v I/O (and the card was not overclocked at all). It was stated on Guillemot's support website to raise this voltage to correct this problem.

so most Mobos run at 3.5 anyways? cool, but i was also thinking that maybe my components might get "used to" 3.5 instead of the original 3.3 and then not be able to switch back, not thats much of a problem, just wanted a few opinions and other peoples experiences to think over before i went ahead and kept it... thanks
