So i searched this site and I cant find anything on overclocking my g3 imac. Saw plenty of dicussion of overclocking, but no info on how to do this, WHat is the general overview of the procedure?

it even shows the proper resistor layout for various frequencies. The author of the page is a genius! There are also other overclock guides on his homepage.
Cool, I have one question though (im really not all that familiar with this), He says to reconfigur R whatever to whatever...Is that like flipping a little switch? Also how dangerous is this? do i need extra cooling?
You're kidding, right?
To overclock a mac, you're going to need to do more than flip a switch or change a BIOS setting; you're going to have to break out the soldering iron and reposition the SMD resistors on the processor board. One wrong move, and your system's toast.
no im not kidding, im THAT ignorant. Just didnt know. If I could succesfully complete this operation, what kind of a boost in performance am i gonna get?(probable) Im currently running a 500mhz, will it be pretty significant? Will i need to install another fan or something like that?
the speed boost depends on how far you push it. and as for the fan, one of the good things about the imac is it never came with fans, but a small speed overclock *shouldnt* need a fan, but due to past experience, i wouldnt go for it and im quite a good solderer :]
Unless you are a soldering god, and have experience de-soldering and re-soldering teeeeny tiiiny little fiddily bits, then i'd recommend you NOT try to OC your iMac. Just my 2 cents tho.
If you've never worked with surface mount resistors I suggest not learning on your imac. If you mess up, or if you go for too higha speed the entire computer could be toast (this is coming from someone with 2 nice shiney g3 door stops)
Yeah, I have tentatively decide that I'm not gonna try it with any working machines yet. But I have a LoBo that was fried when the RAM bay broke and touched pins. Might practice on that. Lots of them little resistors. I have some soldering experience, but never components like this, so Ill brush up a little and then decide. Thanks for the input.
you are going to need a good hot iron (not a cheapo radiohack one) with a good fine point.
yeah i'm borrowing a super nice one from a friend. On of them with the alloy tip that gets hot instantly and cools of in a couple of seconds.
I hope you don't mean the cold heat things??? DO NOT use one of those on components. They work by zapping the solder until it melts. BAD. Get yourself a nice Weller, you never know when you'll need it again.
I'll second that warning. They look great in the TV ads, but the actual item is a piece of garbage. Save yourself the aggravation and steer clear of it. Use a real soldering iron and practice, practice, practice. Once you've got the hang of it, you'll be ready to overclock that bad boy iMac.
Agreed! DO NOT go anywhere NEAR a computer with one of those!!! You could easily kill your iMac with that thing.

Cool, thanks for the advice. The one in question is not a cheapo (i think he paid $100+ for it) But I didnt think about he only way that could work is a controlled High Voltage short circuit...Will look for a weller, thanks.
