As long as the CPU temp doesn't become excessive, you can overclock up to the point where the CPU starts doing strange things like crashing, video splash, etc. Where this max speed comes in is a variable from CPU to CPU.
Some PCI Macs don't like some bus speeds with some CPUs. I assume it is a sync problem between CPU and bus circuits One of my G3/300s runs great at up to 375MHZ, while crashing at 400MHZ. I run it at 350 because the heat goes up by about 10 degrees C from 350 to 375. The 375MHZ speed is still within the "Safe" or "Normal" range according to the spec sheet, but cooler is always better when it comes to electronic component lifespan. This particular CPU has always (purchased new) run hotter than any of my other G3s by at least 15 degrees C. (300 and 400 MHZ, overclocked to 375 to 450 determined by stability.)
