Hi everyone, I'm desperately trying to upgrade my memory on my ancient iMac... I went to the local computer hardware store and they don't stock the correct memory for it. Can anyone link me to somewhere I can purchase online? Or what I need to be looking for? Tech Specs: iMac5,1 Intel Core 2 Duo 2.16 GHz 1 Processor 2 Cores 4MB L2 Cache 1GB Memory 667 MHz Bus Speed I'd like to pump up the memory as much as I can! Cheers!
