    Hi guys, I just got my Mini back from Apple, they installed 1 gig. The mini flies now (duo core), only problem is they scratched the damn casing on the top!! :eek:

    Anyway, I'm ashamed to ask this question as I should know this but here goes. I have 2 256 megabyte SDRAM sticks leftover, and I was wondering if there is any chance it would work in my G4 iBook (1.33ghz, last model). I know the ram is faster out of the mini, but I'm not sure if it would just "kick down" to the ibook's speed? Thanks

    Don't quote me for sure, but isn't the ibook ram DDR not DDR2 ram? your mac mini is intel right? which means it uses 667mhz ddr2 ram, the ibook from my memory since i own the same ibook uses 333mhz DDR. I know for sure that its DDR memory at least. I dont' know if DDR2 is just called that cause its faster than DDR, or if there is an actual size or something difference. The other problem is that I think the mac mini ram is desktop ram and a notebook takes ram with a different pin count and or a different size. So my answer would be no, it won't work with all those differences:) ...sorry

    I don't think so. The RAM has to be in the same "family". The latest iBooks used PC2700 (333MHz) DDR SDRAM. And DDR RAM faster than 333MHz should do fine, but the Intel Mac mini uses DDR2 SDRAM, and that doesn't work in a DDR slot.
    DDR2 is a new RAM architecture and it's generally slower than DDR at the same effective clock frequency, but it makes up for it by going to higher clock frequencies.

    Both freakonguitar and gekko513 are correct...the iBooks use DDR RAM while the Intel Mac minis use DDR2 RAM. They are not compatible with each other...they won't even fit in each other's slots, as they're different shapes.
