Putting Macbook RAM into iMac

[rockstarjoe]

I have a Core Duo Macbook and I upgraded the stock 512MB RAM (2x256MB) to 2 GB. My girlfriend has a Core Duo iMac with the stock 512MB RAM also. Would it be possible to put one of my old ram sticks into the iMac? Or does the iMac have 2x256MB sticks like the Macbook did? I think they use the same kind of RAM, but I wasn't positive. Thanks for any insight.

iMac has 2x 256.

Unless it's the ATI radeon x1600 one, it wont work.

If it is, you could upgrade to 768mb by using one of the 256 sticks in the remaining empty slot.

If it's an intel iMac, the memory will work.
