How to overclock FSB iMac Bondi 233 Ghz to 70/75 Mhz?

[cyberish]

Hi all!

reading this page : http://www.macxtrem.com/articles.php?article=92

I'm wondering which resistors should be moved to achieve 70 or 75 Mhz bus on a iMac Rev.A

thx, raphael

You can't - it's either 66 or 83Mhz bus, and 83Mhz bus will probably be less reliable than adjusting the multiplier of the 233Mhz CPU to say 300Mhz (you will probably be able to hit this).

... why? On a beige G3 it's possible. - Why not with an iMac G3?

The beige G3 does have jumpers for it, but the iMac does not? The iMac CPU card is very similar to a Wallstreet Powerbook, which has the same bus overclocking limitations.
