Remove any overclocking app you have, if you are using one.
Go to the market, download System Tuner app by a developer named 3c.
Set your clock frequency to whatever you want to by opening the app and going to th tab named Tweaks.
Then, once on the Tweaks tab, click Voltage.
On the bottom left, there will be a button that says "-12.5mV", hit that exactly 7 times. That's the safest voltage that I have seen it can go, altough certain phones can go lower.
To the right, click boot setting and click on re-apply cpu settings at boot, and you're set.
You are now undervolted.

Did you give it Super User permission? Did you also hit the cpu tab before the voltage tab?
Gorilla Glass doesn't live up to the hype.
Open Source isn't as Open Source as it used to be :/
