BIOS overclocking + Software FSB overclocking

Okay. I'm away from my main rigs, and I'm curious. So, I've gotta ask.

My main rig runs at an FSB of 227. That's the highest it will post at, but it's stable as well. Voltages on the RAM doesn't matter, multiplier doesn't matter.

So, I was wondering, if I booted at 227, what would be my chances of getting higher than that with a software FSB changer?

it would probally get higher, but be unstable and could damage something in the process
