[G4] Bus speed limits

[Harry Freeman]

Greeting ( + )!( + )

Which means, in other words, if you are going to change the jumpers on  
the processor module then you may as well change the jumpers on the  
current module and achieve a higher speed.

For information regarding G4 Sawtooth Overclocking see;

http://power-mac-g4.com/g4clockup.html

This page has all of the information for changing the jumpers and the  
450 MHz processor should take overclocking to a speed of about 500 MHz  
without destroying itself.

Best regards,

Harry
