Ok here's the deal: I have a dual 2GHz G5, I just added another Gig of RAM to the 512 MB that comes installed. When I turn on the machine and check it, there is only 1 GB listed. I checked to make sure the chips were in the right spot and seated correctly. When I click the more info box in the about this mac window, it is only recognizing my two 512 chips as 256 chips. The ram is kingston pc3200 cl3 RAM. Can anyone help me out here?
