    Default Page file needed on OS drive?

    Well, just as I thought I had this Windows page file thing figured out I ran across a discussion which suggests that Windows needs to have a page file on the system drive even if you have one on another drive and if it does not it will create a temporary one.

    Here are a couple of quotes from the aforementioned discussion:
    If you want to completely remove the pagefile from your system drive, you will need one extra step to Shinrai and mtone's answers. As a comment by paradroid mentions, Windows requires to have a pagefile present on your system drive in order to write kernel memory dumps in the event of a crash. So even if you set "No pagefile" on your system drive, Windows will end up creating a pagefile anyway, even if it doesn't actually use it for paging. Trying to delete this pagefile will show it to be in use. In order to work around this, you have to disable kernel memory dumps, which is also done by going through the advanced system settings.

    Under the "Advanced" tab, in the "Startup and Recovery" section, click "Settings..."

    In the dialogue box that comes up, under the "System failure" section, and the "Write debugging information" subsection, change the drop down menu to "(none)".

    After this, you should be able to delete the pagefile.sys from your system drive (although you might need to reboot first).
    You need a paging file on the OS partition; the minimum paging file size for the OS partition is 800MB (e.g.: for Win7 Ultimate 64bit). ...This could vary, but Windows will tell you if you set it under the recommended size.

    Follow the instructions already posted to set the paging file on the alternate drive.
    Then set a small paging file on the OS partition to accomodate the minidumps and BSOD:
    If you don't set a paging file on the OS partition, every time you boot Windows will create a temp pagefile.sys the same size as your installed physical RAM. So, if you have 16GB of physical RAM, the temp pagefile.sys will be created at 16,308MB (which is a decent chunk out of your System partition).
    Here is a link to the forum discussion quoted.

    Would be interested in any comments regarding the points made in this discussion. Am I mis-reading this or is it just incorrect?

    With an o/s ssd boot drive, I've been running with the swapfile (pagefile.sys) on the first partition of my hard drive for nearly two years.
    Win7 x64 Home Premium warns me if I select a swapfile that is less than 400MB.
    Using a smaller swapfile might not create minidump files when a BSOD occurs.
    I've also tested with no swapfile for several days and had no problems.
    I'm currently using a swapfile on my D: partition with the following settings: min = 400MB, max = 1024MB.
    My swapfile usage is almost always below 200MB. YMMV.

    Don't worry, be happy!

    HCR, you may be sick (and skeptical) of getting advice from the same people. That is fine, I do not whatsoever blame or hold that against you, I encourage it!

    I will only comment about this:

    "If you don't set a paging file on the OS partition, every time you boot Windows will create a temp pagefile.sys the same size as your installed physical RAM. So, if you have 16GB of physical RAM, the temp pagefile.sys will be created at 16,308MB (which is a decent chunk out of your System partition)."

    That is just plain false. You can verify this yourself on your PC now.

    If you still have your pagefile on the RAM Disk, click Start, and then Computer. You'll see your RAM Disk listed with the other drives on your PC. You can see the full capacity and used space of each drive. Select the RAM Disk, right click and choose Properties. You just see that at least half of the RAM Disk is used, we assume by the pagefile. Close that, and double click the RAM Disk to open it. You won't see the pagefile.sys file listed, but it is there, we know because the space it uses is accounted for in the drives Properties that we just looked at.

    If you still have the Computer window up, notice the size and free space of your C drive, the OS drive. Right click it and select Properties to get a better view. Write down the used space, whatever it is, or the free space, or both.

    You know how to set up the pagefile in Advanced System Settings. Start that up just to verify that the pagefile only exists on the RAM Disk. If Windows creates a pagefile on the OS drive/partition, for whatever reason, then it will be shown there. You could see the C drive with the pagefile size shown there, if it has one. If the C drive has no pagefile on it, None will be listed next to it.

    So we begin with NO pagefile on the C drive/partition, and we know the used space (or free space) of your C drive.

    According to that statement I quoted, since you have no pagefile on the C drive, and you have 8GB of RAM memory, if you reboot, you will then find the amount of Used space on your C drive increased by 8GB, and the Free space decreased by 8GB, due to the creation of a pagefile on the C drive. You can also check Advanced system settings for the existence of a pagefile on the C drive.

    If you feel like doing this, let us know what happens.

    Check out RAM, virtual memory, pagefile, and memory management in Windows for information and additional links that should help and hopefully won't confuse you with too many facts.

    pagefile.sys is listed in the root directory of my D: partition and is also visible when using windows search.

    Not in the RAM Disk... HA! I always have show hidden files and folders enabled.

    I'm monitoring it in Performance Monitor now, hasn't used it once, which may be why it cannot be seen. Curious...

    I'm not using the DataRamDisk software; it stopped working after a recent boot.
    Does the ram disk properties show that at least 50% of the total available space is being used?

    I found another freeware ram disk software application but it has quite a few recent version changes.
    I might give it a try when I get a round tuit.

    Yes, it's as it usually is, just a folder listed for Temp files. I can show you this, check the bottom:
