FYI - newer iMac G4s can exceed 1 GB RAM ceiling
Thought I would share this with the community in case there are iMac G4 owners out there who are wishing they could up their RAM beyond the 1 GB ceiling that Apple's specs call for.
After consulting ehMac and Apple's KBase, I was surprised to find there were plenty of users who had successfully installed a 1GB sodim in the expansion slot of their Mac, bringing them well over the maximum amount of RAM. Speculation is that when Apple released this model, there weren't any 1GB sodim modules on the market, which limited users to 2x 512 meg modules.
I snagged a Kingston 1gig DDR 2700 sodim from <a href="http://www.ottcomputing.com/">Over The Top</a> in Ottawa for about $165 (which is about <b>half</b> the price of what Compusmart quoted me!). My memory profile in "About this Mac" now shows that I'm running 1.25GB RAM.
Bear in mind that this will <i>only</i> work on 1ghz (non-USB 2.0) and 1.25 ghz (USB 2.0) machines. The earlier versions (800mhz and below) used a different kind of RAM.
