    Paging File is massive


    Hi All

    Just noticed that on Windows 8.1 my Paging file is set to 16GB, I have this set to system managed on a separate drive. PC has 16GB of RAM and an SSD for the OS.
    Seems to be quite large and recall when previously set to system manage the paging file was only about 2GB.

    Cheers Ged

    Hello Ged,

    You could temporarily turn off the page file to reset it, restart the PC, then turn on and set the page file to be managed by the system, restart the PC again, and see what the size will be now afterwards.

    Hi Shawn, cheers for the reply, tried that and still no joy, even set the paging file on the SSD and it's still the same 16GB used, disabled it on that and reset to the other drive and still 16GB used, seems weird. Have over 400GB on that drive so not a space concern for me, just wondering why it's setting it so high. Maybe I should set it to a custom setting, but would be nice to know what's going on. Wondering has anybody else here noticed it happening with there PC's.

    With so much RAM you really do not need any PF, turn it of or set at 1 GB just in case. Ewen withh 8 GB I do not use PF last couple of years and no program complained about it.

    Hi CountMike
    Yeah I would agree about setting the paging file manually, it would be nice to know why Windows is setting it so high, just checked my Laptop with 8GB of RAM and page file set to System managed and it's only using about 2GB, Laptop also has Windows 8.1 installed. Very strange!

    I would not recommend turning off the page file. Some programs require the page file to run properly no matter how much RAM you have.

    What the system sets the page file to will vary from system to system. For me, the system sets my page file to 4.8 GB with 32GB of RAM in Windows 8.1.

    To be safe, and a good recommendation (Brink), but I would like to support CountMike here.

    Lot's of users have no experience with imaging systems as a saved backup.
    So, having a page file for an average user is a good idea and I am sure some will insist it is a good idea, period.


    My choice, My preference is to not use one.
    In support of CM, I have not had a BSOD since NT4.
    And since Microsoft makes the option available, it is a feature that can be disabled.
    I know of no performance risk or degradation, and I do not need a dump.
    Imaging systems all the time, the page file just gets in the way.
    So does hiberfil.sys.

    I don't agree necessarily with "one must allow Windows to make the decision" ...
    ...have not used a pagefile for 16 years, ...

    My Preference.

    If the page file is turned off, and you either are running a program that requires it or use up your RAM, then you'll get an "out of memory" or "low memory" error, and possibly have Windows crash on you. As usual, this will vary per system. Some may have no issues with the page file off, but others may.

    That's the main reason to never turn off the page file. If you are tight on hard drive space, then it would be best to reduce the size of the page file instead. Say around 4Gb. If you get any of the above errors, then you could just increase the size as needed.

    Ever since installing more than 1GB of Ram per core I turned PF off even when using notoriously Ram hungry programs.I was carefully checking memory usage and not too many programs managed to load it up to limits. It's much better idea to install more RAM than to relay on PF to do the job. If you need more memory, get more RAM, even SSD can't measure up to RAM speed. If you run into trouble , you can always turn PF on easily enough.
