its a powermac (agp graphics). thanks for the recommendations guys. i appreciate it. im going to check them out.homerjward said:i would recommend buying rosewill brand memory from http://www.newegg.com
it's quite cheap and works great in my computer (in sig.) i'm not sure about their non-ddr memory though, and i believe their notebook memory is not so cheap. you didnt say what sort of g4 you have but that might help some people make recommendations.
