Any reason to change I/O voltage?

[sfa ok]

I'm fairly new to this, and I noticed that I can change I/O voltage for the CPU. Is there any advantage to changing this? Risks? If there's no o/cing advantages, why can I change it? Just curious. Thanks.

I gained 3D stability by upping my VIO to 3.5V on my KT7A-R with a GeForce 2 MX.

The only advantage is for O/C'ng. Raising the CPU voltage will help increase stability if your overclocking the chip. It will also make the chip run hotter which is why cooling is so important. If your not overclocking it, you shouldnt change the voltage.

Just got the answer to this question myself. ;-) Raising core voltage increases the signal strength of your CPU making o/c's more stable at the cost of additional heat up to 1.85 is generally safe as long as your temps stay below 50' celsius.

Raising i/o voltage increases stability of your ram. Up to 3.4 or 3.5 again is considered to be generally safe.

I got from 1200@1413 to 1200@1430 by upping my core from 1.75 to 1.85 and upping my i/o from 3.3 to 3.5 and went from 37c idle 39c load, 39c idle 42c load.

Hope that helps,
