Well I had a QuickSilver G4 733 MHz doing nothing so I decided to overclock it.
I looked at xlr8yourmac.com and see that someone with the same model overclocked it to 800 MHz with no soldering - just taking a razor to one of the resistor chips (talk about small) and it let the processor run at 800 MHz.
So I took off the fan, removed the heat sink, took the processor board and to my amazement the resistors on the back were so small I was about to turn back and forget it. But I forged ahead, cut the soldered ends off, the resistor feel off, put it all back together and booted up.
After reaching the desktop it froze. I restarted, this time it didn't freeze and I checked the About This Mac and sure enough it said "800 MHz PowerPC G4"!!
Doesn't feel much faster but what can 66 MHz do anyway? Maybe once I get some thermal paste as discussed a couple threads down and a good soldering gun I will try 1.06 GHz.
