I wonder why such a great feature is being kept "secret"...
It's not. It's common knowlege, or at least was few years ago.
I'm curious to find out what kind of overclocking other ppl have achieve.
I managed to get 96 (always stable), or 97 (sometimes unstable). I had a heatsink + fan from GeForce card. The BVisionPPC board was a Phase5 one.
