Mac Forum / General / Portable Macs / April 2005Max RAM in iBook 500?
http://docs.info.apple.com/article.html?artnum=88234 says that 640 MB is max. But I know that max memory is, partly, determined by what size memory modules are available at the time the computer is released. What is max possible memory? Also, I see only 1 module slot in the instructions. Am I missing something? Only 1 RAM expansion slot? Thanks,  SignaturePlease, no "Go Google this" replies. I wouldn't ask a question here if I hadn't done that already.

"Not Now John" is especially sublime. > http://docs.info.apple.com/article.html?artnum=88234 > [quoted text clipped - 5 lines] > Also, I see only 1 module slot in the instructions. Am I missing something? > Only 1 RAM expansion slot? Yes, 128MB is soldered to the logic board, and so when you put in a 512, that's 640. The next size up would be a gig, and I don't know what happens if you try that, sorry... m.

The memory controller will not address more than 512 MB in the expansion slot. A 1 GB SODIMM would need to be made using 512 Mb DRAM chips, the controller does not work with anything larger than 256 Mb DRAM. Joe OK, one 512 MB module it is. Thanks to all!
