Well, I switched from the stock HSF that came with the retail boxed 1.33GHz Tbird to my Globalwin WBK38 and added some AS instead of the thermal pad. I figured it was time to play around a little with OCing this thing. I was just using the Fuzzy Logic3 to play around. I was able to get the FSB up to 150MHz, giving me a 1.5GHz Tbird! The system was pretty stable at this speed. It would occasionally lock up for a few seconds...the mouse wouldn't move, etc, but then would recover. Problem is at this speed it knocked out the USB ports. I use a USB AnyPoint network adapter, so that's not good. Now I am going to see what's the fastes FSB speed I can get and still use the USB ports. Funny thing is that the temp didn't change at all when I went up to 1.5GHz. It still ran around 39-40C (with the case open). Some numbers from Sandra for ya...
