    Physical and Virtual Memory


    Hi,

    I new with windows 10 and I have some question:
    My OS is win 10 x64 Ultimate and I have 32GB of physical memory but when I checked my virtual I noticed that when was setup for "Automatically manage paging file size for all drivers" was a little more than 2000 MB but when I changed for "Custom size" recommended size was 4982 MB.
    I'm not sure but I thing something is wrong.
    Can someone tell me if everything is OK or NOT.
    Thanks in advanced !

    Memory has not changed in how it is used. Virtual memory is always the size of the amount of physical RAM that you have installed. https://www.techwalla.com/articles/d...ysical-memory_ What is virtual memory, anyway? | LogicMonitor

    When virtual memory is set to be managed automatically, it can grow as needed, so there is no need to always keep it at the recommended full size. The recommended size for manual is based on what is determined to be the minimum size that will never get full and never cause an error because when set to manual the OS can not increase it above what you set.

    In Windows 10 it's best to leave it in automatic for the OS to handle.

    I've got 32 GB on my production desktop. By default, the OS caps Virtual Memory on this system at 4984 MB, but I've never had it go over 2 GB (2048 MB), which is where it's sitting right now, to wit:

    Generally speaking, if a system has 16 GB of memory or more, it won't use VirtMem much, if at all. For systems with 8 GB or less, it's essential, though.

    Well, it does depend on what you are running. My 8GB laptop with Firefox open has a minimal 512MB system managed paging file, but that will expand as demand increases. Run up a couple of VMs and it increases to 2.3GB.

    In the mid-1990s Microsoft invented the myth that the paging file is "virtual memory". I guess "virtual memory" sounds catchy, while paging does not.

    This myth has been perpetuated by the media and public.

    It seems that MS has back-pedaled just a bit, though. They now properly refer to paging as paging, not as virtual memory. But they still say virtual memory in some places.

    Anyway ... there is no way for us to adjust the size of virtual memory. The only adjustment is to the size of the paging file.

    These are some great points. I used to think I could "outsmart" the OS and come up with the best custom setting. I agree it's best to leave it to the OS to handle.

    Agreed. It's usually best to let Windows manage the page file.

    Unfortunately that is all too true.

    In the system applet of the control panel under the heading "Virtual memory" we have this description:
    "A paging file is an area on the hard disk that windows uses as if it were RAM."

    This is a very crude description of the pagefile but does contain elements of truth. But as a description of virtual memory (and many people, including some computer professionals, take this as literal truth) it is a gross distortion. It gives the impression that virtual memory is nothing more than a portion of the hard disk trying to act as RAM, and doing a poor job of it. With that kind of understanding it is no wonder that many people ask the question: "do we really need virtual memory anymore?"

    But as the meaning of terms is determined by usage I suppose we are stuck with that description.

    But in reality virtual memory is so much more. It is a very complex and sophisticated system that provides many advantages to developers and users. Many of the applications we have today would be almost impossible without it. Most applications have no idea of how much RAM is in the system or how much is available. There is no need for applications to deal with those messy details. The OS looks after all of that.
