I just received a stick of 512MB of ebay, and am having trouble getting it to work with my existing RAM.
So here's the situation, and what the stickers stay on each stick of memory:

1) 512MB - PC 2700 333Mhz DDR (this is the new one)

2) 512MB - PC-133 133Mhz

3) 128MB - PC-100 100Mhz

So, number 2 and number 3 above work with each other (which is what I had initially), but when I put in the new stick of 512 (number 1 above), it is not detected at all. The new stick appears to be fine by itself, but is not detected with either stick of my existing RAM.

You definitely need to use the PC133 or PC 100 with your G3 iMac. Also consider that PC100 or PC133 that is compatible with Windows computers may not always be compatible with a Macintosh iMac G3.

The PC133 will work okay SUBJECT to it being low density Mac compatible and if you purchased it from a Mac dealer on eBay. Most PC memory is high density and will not work in your iMac, causing kernel panics.
