    I know Vista 32 bit can only utilize 3 G of RAM. Anything more is a waste.

    How does XP hand that? can it handle 3 GB fine? how about more?

    Windows Xp 32bit registers 3.5GB of Ram, while WXP 64bit will register the full
    4gb.

    Registering the ram is a bit different than actually utilizing it. For example; Vista SP1 32-bit can report 4GB of ram, but is unable to use it.

    Did you notice your article keeps using the word "Virtual Memory"? What is that? More than RAM. RAM+Page File

    Vista SP1 is the 1st Windows to report installed vs available so the poster you are responding to is in fact wrong.

    Same issue. 4GB addressable memory locations, hardware must use some of these. That means the full 4GB is not available to the RAM ever. This is not a Windows issue it is a 32 bit OS issue. 2^32=4GB that's it.

    Any work around you hear about will not improve your performance so no point in doing.
