You can go all the way up to 1.55v before the C2Q CPU's refuse to even boot. I would imagine that because of this, it isn't really possible to damage the CPU by setting the voltage too high so long as you keep it cool enough. Once it hits 125C it shuts down anyways, though I wouldn't push that. They've made these things pretty fool proof it seems.
