    Hi,

    My iMac is the Apple iMac "Core i5" 2.66 27-Inch (Late 2009) , this one: http://www.everymac.com/systems/app...i5-2.66-27-inch-aluminum-late-2009-specs.html

    I read that it can take 32GB RAM. I'm using Win7 64 bits. Can I put 32GB? Is it worth it? I have 8GB now.

    One other thing: My wife has the "Core 2 Duo" 2.66 24-Inch (Early 2009) with the original 4GB RAM.

    Can I put my 8GB RAM (the ones from the 27" iMac) on the 24" one?

    Thanks for your advice.

    The same speed PC3-8500 1066MHz is used in both so should not be an issue transferring the 8GB to the early 2009 machine. I have heard conflicting stories about whether the i5 and i7 late 2009 can take 32GB RAM. What I can tell you is that I have 16GB of 1333MHz RAM running happily in my late 2009 i7 machine so if you are having trouble finding 1066MHz sticks you should be OK with 1333MHz sticks.

    Some 1333 memory will work in the late 2009 i5/i7 not all. Otherworld Computing has 1066 memory for the late 2009 that will bring the system to 32GB but it is at a premium price.

    Are you running programs that require 32 GB of RAM ? I have typically found a 8 to 16 MB is the sweet spot in my machines for photo work. Can't tell you about video production - I probably wouldn't use an imac for this anyway as this video / sound is the forte of the MacPro.

    That's what I thought... Probably not needed.
