I recently added 1GB of RAM to my iBook G4 12". I used kingston RAM. It does show that my MAC recognizes it however, I've since uploaded about 5 cds into my iTunes and it started telling me there is no more room on the startup disk again. Am I missing something or did I do something wrong? Any help with this would be much appreciated as I'm going out of my mind with this. I should also mention that I bought an external hard-drive prior to adding the memory and I wasn't able to sufficiently run many programs with the use of that either.
