    Prakash can you believe it also depends on the OS? Windows does not support more than 4GB of RAM, if you want to use more ... then you have to go for the Enterprise version.

    Enterprise version? tsk tsk tsk.
    In OS it depends if your OS is 32-bit or 64-bit.
    32-bit will can address till 4 GB.
    and 64-bit can address till 16 TB.

    P4 can address upto 4 GB maximum.

    Every single Edition of Windows XP/2003/Vista/2008 comes in 32-bit or 64-bit versions. And the maximum addressing capability is the same as I mentioned..

    except for some 32-bit Windows editions as you mentioned.
    I found that some 32-bit editions support upto 64 GB by using the extra number of address lines (4 to be precise) provided by the Intel Pentium Pro and above processors, called as PAE (Physical Address Extension).
    On Windows this mechanism is called AWE (Address Windowing Extensions).
