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.
 
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.

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?
 
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.

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

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.
 
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.
