    I was looking at macsales for memory for our new iMacs which are on their way here and noticed that it says the Mid 2007 iMacs we have can support 6GB RAM.

    I thought I saw an apple page that lists all the iMacs and what the supported RAM was. The 2007 was max 4GB.

    Is Macsales correct? It says it can hold 1 4GB chip and 1 2GB chip.

    Not a huge deal as the kids should be fine with 4GB. They are getting our old iMacs.

    Here is page on Apple.

    Cool thanks! So it can reference a single 4GB but not 2 of them? A little odd. I guess the 2008 Core 2 Duos with the nvidia chipset went to 8gb. See a lot of conflicting info even with Intel's chipset descriptions.

    Even the Understanding Intel MAC Ram here doesn't show an iMAC with 6GB, though it is the exact Santa Rosa chipset that is in the MacBooks which do 6GB. Maybe the link is out of date.

    Guess I could bump these up to 6GB since Memory is relatively cheap.

    Could you cut and paste your Hardware Overview, minus the serial number of course?

    Mine is :

    Model Name: iMac
    Model Identifier: iMac7,1
    Processor Name: Intel Core 2 Duo

    Was there any noticeable performance increase when you went from 4gb to 6gb? I'm running Yosemite on the same iMac and it's almost unusable. SO slow...

    Not a huge amount but I did see it.

    Your performance issues could be due to other circumstances and not just the RAM. Perhaps you could post an EtreCheck report of your system and we can look for obvious issues going on with your system.

    If you aren't aware of EtreCheck, please Google it and then post the report in your reply.

    I have only 3GB of Ram in my iMac 20" 2007 Mid and it running Yosemite alright, can be a bit slow but usable.
