    All,

    I have Vista Ultimate x64 Extreme, with 8 GB of memory, Q9300, and 2
    velociraptors. I do NOT overclock, but would like Vista to use more of
    the memory.

    Typical load usage of memory is 2GB - about 25% of my total memory
    Maximum use of memory was 3GB -

    I would rather have Vista use memory than to use swap file. How can I
    get this done?

    Regards, AraiBob

    Run more memory intensive applications. The OS automatically uses all
    of the memory it needs. If you're not doing advanced 3D modeling, or
    high-end video editing, you've likely no need for that much RAM.

    Vista doesn't have a swap file, although it does have a page file
    (similar, although not the same concept)

    What makes you think Vista is paging at all?

    Sorry, 'page file'. I use "swap file" and "page file" interchangeably
    Old O S programmer Slang is still slang. I don't have specifi
    'knowledge that the swap file is in use, however, The Performance tab i
    Windows Task manager has these values that make me think so

    Total Physical Memory (MB
    Total 819
    Cached 6712 << using the page file
    Free 2

    Page File 2300M / 16565M << using the page file

    Kernel Memory (MB
    Total 38
    Paged 294 << using the page file
    NonPaged 8

    I have also seen threads on this topic (some time ago) and they note
    that even when there is lots of memory MS insists on writing things t
    the page file

    As far as I understand it, no. Here's a bit from MS themselves:

    Pagefile

    RAM is a limited resource, whereas virtual memory is, for mos
    practical purposes, unlimited. There can be a large number of processe
    each with its own 2 GB of private virtual address space. When th
    memory in use by all the existing processes exceeds the amount of RA
    available, the operating system will move pages (4 KB pieces) of one o
    more virtual address spaces to the computer’s hard disk, thu
    freeing that RAM frame for other uses. In Windows systems, thes
    “paged out” pages are stored in one or more files calle
    pagefile.sys in the root of a partition. There can be one such file i
    each disk partition. The location and size of the page file i
    configured in SystemProperties, Advanced, Performance (click th
    Settings button).

    A frequently asked question is how big should I make the pagefile?
    There is no single answer to this question, because it depends on th
    amount of installed RAM and how much virtual memory that workloa
    requires. If there is no other information available, the norma
    recommendation of 1.5 times the amount of RAM in the computer is a goo
    place to start. On server systems, a common objective is to have enoug
    RAM so that there is never a shortage and the pagefile is essentially
    not used. On these systems, having a really large pagefile may serve n
    useful purpose. On the other hand, disk space is usually plentiful, s
    having a large pagefile (e.g. 1.5 times the installed RAM) does no
    cause a problem and eliminates the need to fuss over how large to mak
    it.

    Considering your max ram usage you know of is 3GB, I doubt your pag
    file gets much use, as it's rare for a user to actually need 8 gig
    unless they use some high end multimedia rendering software

    The OP is running the 64-bit version of Vista... the 3GB limitation is
    for 32-bit.

  7. You can disable the paging file if you want, but this might cause problems.

    Sirs,

    I just noticed that under my ID it says, Newby. I am a newby to this
    site, but I have been programming professionally since Feb 1970. I have
    been an O S programmer, a D B A, and a whole host of other jobs in my 37
    years. I have used more than 30 programming languages (After assembly
    all other languages are so so easy). I retired in 2007.

    I built my newest PC in Nov 2008, and put 8GB memory so that it would
    NEVER have to swap / page program or data. I also installed Vista
    Ultimate (first time to use Vista). I had the notion that Vista was a
    'real' OS and that I could set parameters that would manage this kind of
    thing. I just don't know the RegEdit places to do such settings.

    I have seen recent emails and articles stating that such an option does
    exist. In fact, on page 33 of the July 2009 issue of Maximum PC notes
    the product TweakVI from TotalIdea has exactly this setting. What and
    where is this setting? What are the correct values?

    Regards, AraiBob aka AwryBob aka ArayBob

    The OP is the one that mentioned the 3GB, I can read. He said:

    Typical load usage of memory is 2GB - about 25% of my total memory
    Maximum use of memory was 3GB

    I only mention it because this is actually one case where a more
    traditional "swap" system and Windows "page file" system are very
    different, and understanding those differences are critical to
    understanding pagefile use.

    Cached is actually the opposite, this is memory that is otherwise
    available, but is being used to cache something on disk in memory.

    So despite being used, this is as good as free RAM in that it can be
    released at a moment's notice, but should the resources that it's
    caching become needed, it will result in a performance increase.

    >Page File 2300M / 16565M << using the page file?


    Page File is a bit of a misnomer here, this actually indicates that,
    aside from caching, the OS has 2300M of allocated memory to running
    processes.

    This allocated memory can be backed by physical memory, or by disk
    (either in the pagefile, or elsewhere in many cases.) For example, when
    a large program loads into memory, the EXE or data files are mapped to
    memory, but the data is not necessarily kept in memory at all times.

    Rather then writing data back out to the pagefile, Windows know that it
    can release the memory when needed, and re-read the original data from
    disk on demand.

    The pagefile counter gives you an idea of the total number of allocated
    pages in use, when combined with the data from the Memory tab, you can
    get an idea of how many pages would need to come from disk vs physical
    RAM.

    >Kernel Memory (MB)
    >Total 382
    >Paged 294 << using the page file?
    >NonPaged 87


    "Paged" here is actually the kernel's version of a pagefile, it's not
    necessarily paged to disk right, but rather, it's the memory that is
    paged (whether those pages are in RAM, in the pagefile or elsewhere on
    disk), vs NonPaged which is address space directly used by the kernel
    (typically for lower level drivers, and lower level kernel components
    including the paging subsystem itself)

    >I have also seen threads on this topic (some time ago) and they noted
    >that even when there is lots of memory MS insists on writing things to
    >the page file.


    Many things are actually paged automatically, but few are actually
    "written" to the page file as much as just space in the page file is
    reserved.

    For example, if an application requests a 1GB chunk of memory address
    space, but doesn't write anything to it and the OS can't immediate
    satisfy the request from available memory, this address space is "paged
    out" to the pagefile without anything actually being written (although
    the pagefile may be expanded to satisfy the memory request) -- This is
    the most common situation people are referring to when they talk about
    Windows insisting on writing some things to the page file.

    In your case, with the ratio of total ram minus cached vs the page file
    allocation being where it is, I doubt you're seeing any performance
    impact due to paging.

    You can set up performance counters to monitor page file use as well as
    read and written pages if you want, but unless you're doing something
    that uses 8GB of memory (virtual machines, video or large photo
    encoding, etc) I'd be surprised if you ever see any significant amount
    of any data being written to the pagefile.

    Thanks for the great explanation of the ctrl-alt-del display.

    It would seem that having 8GB of Dominator memory in my PC is waste
    electricity

    Perhaps I should remove 4GB and hold them as 'backup' in case the 4G
    memory left should die

    Best regards, AraiBo

    As to the numbers you posted earlier, you have 28 MBs of free RAM - all
    the rest of the 8190 MBs is used. So all the RAM is practically used. I
    don't see a RAM usage problem.

    Given that the "Free" memory is so low, I'd leave it in, even if all
    your RAM isn't actively being used, it's still being used by the OS for
    caching, so it may improve performance (or it's possible you were using
    more RAM previously, and said apps have quit)

    RAM doesn't use much power, and since you've already paid for the RAM
    itself you've paid the biggest portion of the cost, so I'd keep it in at
    this point, at least if it were me.
