I have successfully overclocked many a beige G3, and since the yikes uses jumpers, it should be overclockable using the same procedure as I used on a beige. While you are experimenting to find the new clock speed, avoid doing any work that is irreplaceable. If you have to work on something important, SAVE VERY OFTEN. Only go up one step at a time. ie from 400 to 450. Use your system for a while at each step to test. Make sure you close up your system when you test it. The primary limit with overclocked cpus is heat. You want to test it in real world usage. As you are testing, run something fairly processor intensive to heat up the cpu. Running Chess in computer vs computer mode will do. The FIRST time you get a system freeze, STOP. Back down 1 speed step (2 if paranoid) and run from that speed. Following this advice SHOULD protect the cpu from any damage. Adding an extra fan may allow you to get more speed (a step or so). Adding a liquid nitrogen cooling setup may let you get up to 1GHz or more with the 400 mhz processor, but is probably not cost effective. But it will get you MANY geek points. Anyway, my wild a## guess is that you can safely take it up 1 notch in speed and maybe 2. Just remember, until you have gone a week with no system freezes, save VERY OFTEN. My overclocking experience comes from the following systems: 6100/60MHz taken up to 75MHz (it ran at 78 long enough to do a macbench run before freezing) 266MHz G3 beige up to 333MHz 350MHz G4 zif from a yikes in a beige up to 433MHz But remember, all systems are different. You may not even be able to get 1 speed step out of your yikes, or you may be able to get 3.
