Microsoft Windows 7 Ultimate Edition - Maximum Page File Size

    Question

  • Hello Everyone,

       In Microsoft Windows 7 Ultimate Edition, what is the maximum size possible for the page file (swap space). I am intending to move my swap file to an ioDrive, and the maximum page file size will determine the capacity of the ioDrive I will need to purchase.

       Thanks to all respondents.

  • Windows support 16 page files.

    The max size is 4095MB on a 32Bit Windows for each page file, running the normal kernel. 32Bit Windows with the PAE KErnel and the x64 Version support 16TB for each pagefile.


    Is this what you want to know?

  • Vickreman,

    The recomendation is this formula:
    (Amount of RAM memory in your machine * 1.5) = Maximum size of your page file.

    A frequently asked question is how big should I make the pagefile? There is no single answer to this question because it depends how much RAM is installed and how much virtual memory that workload requires. If there is no other information available, the typical recommendation of 1.5 times the amount of RAM that is in the computer. On server systems, a common objective is to have enough RAM so that there is never a shortage and so that the pagefile is essentially not used. On these systems, having a very large pagefile may serve no useful purpose. On the other hand, disk space is usually plentiful, so having a large pagefile (for example, 1.5 times the installed RAM) does not cause a problem and eliminates the concern about how large to make it.

  • this formula is old and useless. Let Windows Manage the size !

    This is the way Windows sets the size when it manages it:

    System Memory Size

    Minimum Page File Size

    Maxmimum Page File Size

    < 1 GB

    1.5 * RAM Size

    3 * RAM Size

    >= 1 GB

    1 * RAM Size

    3 * RAM Size

  • Hi Andre,

       My question is not how big I should make the page file. My question is:
    What is the maximum page file size that is supported in Microsoft Windows 7 Ultimate Edition?

       Thanks.

  • Wow, 256TB!  I think he's saying that's the maximum?  I you wanna max that out, have fun hooking up your SAN.
