    I have 4GB of ram installed on my iMac but when I start up windows it tells me I only have 2.3GB. Is this normal?

    It sounds like you are running a 32bit version of Windows....

    Unless you are running a 64bit version of Windows you wont see all the ram... :( only the 2.3...

    32bit versions see up to 4GB, any more above needs 64bit system to be seen. So it's not that.

    Having the same problem, have 4GB on a 32bit system but only 2.73 "is usable."

    That's normal because the 32 bit version can only use around 3.7 GB of regular ram + video RAM. My macbook has 8 GB ram and a nvideo 9400, i guess 256 mb video RAM, and only see 2.3 GB. Apple has some other limitations that take a whopping 1.4 GB of integrated video RAM.

    64 bit windows will see and use the full 8 GB.

    Gramps, what the hell am I paying you for?
    Yes and no and maybe. If he has a discrete graphics card, the amount of ram on it is counted against the 4GB total on a 32-bit OS.
