[QUOTE="JGO, post: 26218"] Thank you for the information, the link to the apple developer site was especially informative. It is not that the Apples need their own RAM, it is that the BIOS is incapable of addressing "high density" RAM. In other words you can have a maximum of 256 mb in a logical bank on a DIMM, so a 512 MB Dimm would have to have two 256 MB banks made up of no more than 32 MB per chip on the Dimm. So if you get a Dimm that either addresses them as one bank (this is my scenario) or perhaps uses only 8 physical chips that are 64 MB a piece, then it won't work. Thanks. [/QUOTE]
