    I would like a definitive answer as to how much memory Vista Ultimate 32 bit will support.  I have read all kinds of answers, most say 4GB but there seems to be a conflict in opinions.  I'd like to hear from anyone who absolutely knows the answer.  Thank you.

    Answer:
    4GB - (total videocard RAM) - (address space needed by other hardware.)

    (Yes, I'm pimping my own post...)

    It's not a Windows 'problem.'  Rather, it's a limit of 32-bit architecture (and, therefore, a 32-bit OS.)  Vista (as of SP1) will report (in System Properties) the total installed RAM; however, the amount that's actually usable (addressable) will depend on your total hardware config (and will be the value shown in Task Manager.)

    If you're still in the planning stages, and you really want/need to make use of 4GB (or more) RAM, I'd recommend that you go with x64. 

    HTH,
    Chris
