333mhz iMac overclocking

Heya, I posted a while back about some iMac's at a school where I work that were going to be junked since they had busted CD-ROM's (the cost of repair being higher than the value of the iMac's).

I managed to get 'em going again using standard CD-ROM's, and was given one of the iMac's in recompense for it. It's not a bad little machine --it's a 333mhz rev. d iMac (one of the last tray loaders) and really works just fine.

For a project I'm going to rebuild it as a desktop (rather than integrated with a CRT) machine. Having all the parts spread out got me thinking about overclocking --problem is, I see absolutely no jumpers or dip switches on the board.

Nor can I find any articles online about overclocking these machines.

Anyone know if it's a lost cause and I should just make due with the 333mhz? Obviously I don't intend to game or anything anyhow, but I thought it'd be nice to have the machine a little bit quicker.

Well, any kind of overclocks that you do get out of it will have a negligible effect on preformance. I would say upgrade the RAM if you're going to run OS X, or try Yellow Dog Linux, preforms quite well on older Apple hardware.

If you must overclock, it usually involves the desoldering and resoldering of resistors. You can usually find informations, but some Macs have never been overclocked.
 
When I overclocked my Yosemite G3 from 300MHz to 400, I noticed one hell of a performance gain. Of course, sticking more RAM in it will probably be needed, too. The 192 in our original iMac is farm from enough; the 288 megs in that blue+white G3 I overclocked was very much closer to enough. It would still do a lot of caching on the hard drive, but far less than the iMac.

So... get it up to 256+ megs of RAM and OC it. It will be much smoother.
