I remember doing this too, it unlocked the multiplier which they locked at the factory by slicing through some metal blocks with a laser. My Duron 600 would run at 800 with a normal cooler & fan, then I added a really loud Delta fan and a copper heatsink and it was stable at a magical 1Ghz. Eventually I got cocky enough to solder a resistor between a certain pin on the motherboard and earth which effectively increased all the voltage settings in the BIOS so I could push enough voltage through it to run at 1.2Ghz - it ran like this for years as my only PC. Good times :)
