I bought my iMac G5 with a stock 512 stick of RAM in it. I put a 256MB stick in to (at first) but 768MB was not enough. So recently I pulled the 256MB stick and put in a 1GB stick from this website:

I have bought RAM from them for 2 iMac G4's, an iMac G5, and an iBook G4 and have had ZERO problems in the 2 1/2 yrs I've been using their RAM. Plus the 1GB stick for the iMac G5 was/is $165.00.

1.5GB is great in the iMac G5.......seems a lot faster than before.

I am debating what to do - either 1 or 2 1GB sticks. But I agree, 512 is not enough. (Less than my G3 iBook.) As I bought the iMac from the store and wanted the BT I had to take the 512, otherwise I would have taken 256 and upgraded.
