Hello everybody, this is my first post but I am a long time lurker. I came across a Dual Core 2.0ghz G5. it currently has 4gb of memory and a 160gb hard drive. I have read on the internet that some of the Dual Core G5's can have a max of 4gb of memory and some can be 8gb. How could I identify this G5 and find out what I can and can't do it it? Thank you! edit: Following this site, so it would seem that if the G5 has 8 slots, it can take 8gb of memory? http://support.apple.com/kb/HT2248 So 4 slots are restricted to 1gb in each slot?
