I/O Voltage...

When o/c'ing, should I increase the I/O voltage at all?...or leave it at 3.30 default

In my experience it has a little bit of affect on stability. If you get a bit unstable in Overclocking a CPU try pushing it up to 3.5 or 3.6. In my 2 Durons 1 a Duron 650 @ 1028 and a another 750 Duron @ 1000 I have the I/O at 3.6 with no ill affects and they run seti 24/7. I have not seen a heat increase with increasing the I/O. So in summary my experience with increasing the I/O has not hurt anything but gain me stablity. I have at different times used 3.8 I/O but do not see any beneficial gains from going that high. I would try a slow and logical progression to upping the I/O as when overclocking there are other components that can cause instablity and not neccesarily the CPU itself. But with the I/O voltage going up some to see if it helps should not hurt anything for testing purposes and may help increase stablity as when you OC you need more I/O and Core Voltages in many cases. This advice comes with not knowing what System you have and so forth so take care.

Hope This Helps Some

Thanks for the advice...

My system is:
Abit KT7-RAID
Athlon 1.1 200 FSB
Volcanoe II HSF
Asus V8200
384 Pc-133 Micron SDRAM

I have a KT7-Raid for both of My Duron's so we are equal ground there. and I have 512 meg of Crucial Ram in my box so with knowing your system is alot like mine. I have alot of confidence in the advice I gave. I hope it helps. Lemme know I will try and help all I can. I am using a FOP-38 with a 40 CFM 7500 RPM Y-Tech fan to keep things cool here. And all is stable. Also I am running both Duron @ 266 FSB (133X2) the L1 Bridges are crossed and unlocked. You can do the same with your Chip if the bridges are unlocked as I have guessed.

You got your FSB to 133 with KT7?...

Mine becomes unstable at 104
