    Im am properly pushing my luck running vista on a :-

    2.8ghz processor

    1gb ram

    360 and a 80 Gb SATA hard drive

    256 Video card

    Soundblaster audigy ZS

    The problem is when im on the desktop, I am using 57% of my memory on the
    computer. I was wondering If anyone had any ideas on how i can lower this

    Tom.

  2. Vista uses as much RAM as it can for whatever processes, programs are
    running.. if it gets close to running out, it rapidly reclaims whatever is
    required..

    Free RAM is wasted RAM..

    57% still leaves a useful 400mb+ so it's not the end of the world.
    What you could do is to have a look at what is running on your system.
    I used...
    http://www.microsoft.com/technet/sysinternals/utilities/Autoruns.mspx
    and found loads of crap just wasting RAM at boot up.

    NB. It's worth taking your time over it because although there RAM to be
    saved there are essential tasks that can be knackered too.

    Start with any non Microsoft software you may have trialed since
    they often leave their mark even after Install.
    Also look out for crap your PC vendor may have installed but is of no use to
    you.
    Often you'll find ISP software other than your own which is wasting space.

    Additionally you could get a freeware RAM defragmenter from Download.com.

    Yeah, but it's still nice to have a lump.

    I know for sure that Vista with 2gb RAM running at 50%
    runs quicker and smoother than with 1gb at 100%

    Why since it's of no use?

    Vista does a much better job of memory management than XP. It tries hard to
    find a use for all memory, caching files and programs based on past history
    so they are available in fast RAM if you need them. If another process
    needs memory, it is freed from caching and available. The myth of having a
    bunch of free RAM is just that, a meaningless myth.

    And what exactly is that supposed to do? Do you have any objective test
    results to show this is anything but a snake oil product?

    This makes me wonder... what happens to the stuff sitting in RAM when you
    open a RAM hungry app. Is it moved to the page file? ("rapidly reclaims") If
    Vista loads data into RAM on speculation and then has to move it to the hard
    drive... doesn't that slow the whole process down?

    So you can load more apps without knocking the current ones out of RAM.

    It was a afterthought. I'm not sure.
    Noted.

  12. That is the essence of a page file.. it allows for the programs that require
    physical RAM most to get it, while not putting a limitation on what can be
    opened up to and no more than the total physical RAM installed. While page
    files are slower than RAM, the user would still not be sharp enough to
    detect any difference in general use..

    The page file/swap file system works very well, and is used on machines
    above x86 architecture.

    That makes no sense.

    Whatever...
    I know a system runs better with 50% of 2gb rather than 100% of 1gb.
    I don't care how... it simply does.

    Sorry I hit send too soon. What Vista does it examine the use patterns to
    see what programs are commonly run and what data is used. This reassessment
    goes on regularly. It then caches the programs and data in currently unused
    memory. If you then start one of these programs the data is already in RAM,
    hence faster. When you start a program that is not cached and the program
    needs some of the RAM that is being used for caching, Vista makes that RAM
    available. There is no performance hit with this. Something has to be in
    the RAM, whether it's all zeros or cached programs and data, there is no
    difference if the RAM is "unused' or prepopulated as a cache.

    What does take system resources is populating the RAM with the cached data.
    You will see when Vista boots quite a bit of activity. You can watch it in
    a way by opening task manager, go to the performance tab and watch the
    numbers under free RAM change as data is being cached.

    Vista periodically reassess and changes what's in the cache.

    There is no advantage in having RAM unused.

    So adding RAM to a working system is pointless?

    NO because more RAM means more cache which means more speed and less reading
    from disk.

    Makes sense. (the question was sort of rhetorical)

    That is also the beauty of the genius "ReadyBoost". Instead of quickly
    moving the cache to disk it can move it to the flash drive whichto 10x
    faster than disk access. If not using readyboost,I would really suggest
    doing so considering how cheap they are these days.

    No, I didn't say that. More RAM will allow more items to be cached for one
    thing, but it doesn't matter how much RAM there is, there is no advantage to
    having that RAM free. If it's free it's wasted.
