Hi all. I have a slot-loading iMac G3 that has been sitting unused for a while and I'd like to do what I can to make it run its best. It is a 400MHz graphite model with 1GB RAM, AirPort, and a 160GB HD (seen as 128GB). I know I have the RAM maxed out, and I plan on purchasing a CF card + adapter setup to replace the HD, so that leaves me with the processor. I have found a 700MHz logic board, and it's the same shape as my current one, so it seems like it would fit fine but does anyone know for sure? Also, I found a guide over overclocking these iMacs by changing the resistors on the logic board. They list speeds of up to 1GHz. Would that be safe for the iMac or would it not run at 1GHz? There are a lot of speed bumps on the list that would be an improvement over the 400MHz without having to buy a new board - any comments/suggestions? http://lowendmac.com/macdan/md09/imac-dv-clockup.html Thanks in advance!
