Windows-7 x86 or Windows-7 64 that is the question RRS feed

  • Question

  • Okay using my MSDN subscription I've downloaded both the x86 and 64-bit version of Windows-7.

    I have a few questions before installing one of them though...

    1) What is the max memory that Windows-7 x86 will see? I have 6 Gb of Ram on the motherboard of this system.

    2) Will a Intel Core Duo CPU E8400 with Physical Address Extension support the 64-bit version of Windows-7?

    3) If this system will support the 64-bit version of Windows-7, can I run our existing suite of 32-bit applications or would I need to aquire all new 64-bit versions?

  • Anyone out there who can answer these three simple questions?

    1) What is the max memory that Windows-7 x86 will see? I have 6Gb of Ram on the motherboard of this system.
    2) Will an Intel Core Duo CPU E8400 with Phyical Addrtesss Extension support the 64-bit version of Windows-7?
    3) If this system will support the 64-bit version of Windows-7, can I run our existing suite of 32-bit application or would I need to aquire all new 64-bit version?

  • 1). X86 version, 32-bit, use 4GB max (2^32bytes).

    2). Please query the Intel product list: http://ark.intel.com/products/33910/Intel-Core2-Duo-Processor-E8400-(6M-Cache-3_00-GHz-1333-MHz-FSB) supports 64-bit

    3). No, you have to install the Win 7 X64 new version. Cannot upgrade from X86 version.

    Please post your Windows OS usage questions on the Microsoft Answer forum: http://answers.microsoft.com/en-us/windows/forum?tab=all

  • I think that you misunderstood my third question:

    I wasn't asking about upgrading the OS from x86 to 64-bit, I was asking if the 64-bit version of Windows-7 would support our existing suite of 32-bit applications?
