I have 2 GB of PC3200 RAM. Task Manager reports that I have 800 MB available but I can't open anymore programs or windows, the programs reports "Out of Memory" error. I'm beginning to think whether its my video memory (64 MB DDR) that needs to be upgraded or if it's the Win16 subsystem that's out of memory. I don't have a clue.

If you have 2 gigs of physical ram and only 800mgs free, then you must have an enormous number of running programs.
I have 2gigs of ram and 32 active programs, but they only use 486mgs of ram.
You may have very low virtual ram. That's something to check!
Open the task manager and see what is using so much ram and turn it off. Then watch for the warning again. You may just need a good defrag and Chkdsk, to put things back in place or your hard drive may be getting too full. That warning comes up a lot if your drive is getting too full.

Maybe some info here helps:

Also right click MY Computer,
then Properties.
See what it says on how much you have.

Yeah I intend to make full use of my 2 GB RAM ^_^, hence the large investment. My C drive is 20 GB with 5 GB free. Diskeeper reports that my C drive is "Healthy", not fragmented. My virtual memory on C drive is set to 2GB-4GB. According to task manager, I'm using only 1.5 GB under "Commit Charge". So has video memory been ruled out as a possible suspect?

"Yeah I intend to make full use of my 2 GB RAM"
- what programs will you be running? Audio/video encoding? AutoCAD?

????Commit Charge????
What is that?
It is NOT part of Windows, so I would turn it off.
As far as your video card goes, it would not be sucking your ram to death. Your video would use its own (64mg) ram and then become sluggish. It would not cause the problems you have described.
It sounds like you have a nice unit. I would turn that "Commit Charge" off and then find out what it was. Maybe remove it from the computer.

rs008f, try this:
1. Open notepad.
2. Type this script exactly as it is:
Freemem=Space(1000000000)
3. Click File, then save it as filename.vbsNote: I indicated 1GB in there. If you want you can increase it to 1.5GB, but do not increase it to exactly 2GB or you will suffer slowdown.

I refer the person that says to turn off the commit charge to read this page.
Now if you have used 3/4 of the drive and have virtual memory set to 2 to 4 gigs that could be why you're getting low memory. Actually I think it trying to tell you that you're running low on drive space. When you get to a certain amount of drive space used and so much left that it's unable to run properly then you get a warning.
As for the video memory. If you have a agp card and it has 64 megs of ddr ram then it's got plenty of ram for most applications. I suspect you have an Nvidia MX400. The only way it would intrude on the system ram is if you tell it that 1 it's ok to do so and 2 how much it can use.
Now with as nice a rig as you have why not take it a step farther... Get a Maxtor or a Western Digital or even a Samsung 80 gig drive and set it up as the secondary drive. These drives can be had for very reasonable cost in the area of 60 to 80 bucks.
You're running out of drive space as was brought up in another reply. HTH

By having 2-4gig of pagefile you are slowing your system down and wasting disk space.
Paging is the SLOWEST memory operation the computer can perform. To optimize you reduce the pagefile to what your system needs minimally.
Want to optimize your memory usage? Set pagefile to none. With 2gig of ram you DO NOT NEED A PAGEFILE.
Video ram will not give you a memory error message. You can not tell a add-in video card to use onboard ram. Two different subsystems. You can only tell a onboard, built into the mainboard, video which uses system ram and then you are limited to the choices available which usually are 32meg max.
I will refrain from commenting on the previous posts. OMG is there some misunderstandings about computing here.

Yeah, I don't know WTF taht was all aobut but don't listen to setishock. The only semi good point he makes is that you may be low on disk space, not memory space. Might want to check that.

First of all, there's no reason to have that big of a pagefile with that amount of RAM. And if you're running 1.2 GBs worth of programs at the same time, you can expect there to be problems.
Second of all, you should probably ignore what wanderer said; that is, don't disable the paging file. Some programs will allocate huge amounts of memory (sometimes in the hudreds of megabytes) that they typically never actually use. This memory is usually stored as virtual memory; however, with virtual memory disabled, this is all stored in RAM. Seeing as you're already using 1.2 GB of memory (on god only knows what), your system would likely quickly run out of memory.
Finally, x86 processors being 32 bit, 32-bit Windows is only able to address up to 4GB of memory. Since Windows, on a higher level, handles both types of memory the same (RAM and virtual) and simply creates a page fault when it wants to load virtual memory into memory, the TOTAL of your virtual memory and your RAM memory cannot exceed 4GB.
"2 GB of RAM"...
"2-4 GB Pagefile"...
I'd set my pagefile from 100MB to 1000MB if I were in your shoes (and possibly bring it up higher, if need be)

Well ryan if you read all of the posts then you would see we all have said the same bloody thing just in different ways. I got long winded and for that I'm sorry. But in a nut shell>
No the video card won't affect the system ram. The video card will throw errors of its own
Yes leave the pagefile turned on and IMHO set it to let windows manage it. It will vary in size as the space is required.
And I still think a bigger drive or a second drive would help out a whole lot.
And finally windows is imfamous for poor memory management. Find an external memory manager.

Thanks for your inputs. Although I have to say that I'm still not clear what the solution is because of clashes of opinions. I have 2 GB of RAM because I surf a lot (15 IE browsers opened usually), and do a lot of multimedia stuff like encoding videos (Divx, MPEG-2, etc). They do take up a lot of memory. As for HD space, I have 3 HDs. 1 ATA-100 WD 100GB (20 GB partitioned as C drive), 2 SATA 250GB. My video card is an ATI 8500DV (64MB). BTW, Commit Charge can be found in Task Manager. I think it is the pagefile usage. The only adjustment I've made after reading these posts is to let Windows manage my Virtual Memory instead of using a custom size. Hopefully, this will solve my problem.

By letting Windows manage your pagefile you will continue to slow your system down.
Can you at least try setting pagefile to none??? So you can see the difference??
Sure you are going to find all the suggestions confusing. Microsoft can't even get their own documentation correct on the subject.
2gig of physical ram is overkill for everything you are doing except perhaps the music editing.
Sure there are lots of opinions and you have to sift through them. But apply common sense to them and see where they go.
For example the comment Windows is known for bad memory utilization. That is a hold over from the msdos based days of 9x/ME. W2k/XP do a excellent job and require no 3rd party memory managers.
If windows can only address 4gig then what is it going to do with 4gig of physical ram? Automatically not have a pagefile? Doesn't work that way. Doesn't matter how much physical memory you have the OS still reports 4gig of ram to a program. This is all part of the shell game of memory/program management.
Setting your pagefile to none will hurt nothing. I run with 768meg and for a year and have loved XP. Certainly is quicker and more reliable.

wanderer is right i surf all the time burn dvds and most other stuff you can imagine
inc video editing and macking my own home dvds with just 768 mb of ram and no page file i have been doing this for over 2 years now and have no side effects at all
blue raja is full of it
and has never tried it obviously he seams to only quote from ill informed scourses and not from experience
give it a go you wont look back

"...with just 768 mb of ram and no page file i have been doing this for over 2 years now and have no side effects at all
blue raja is full of it"I never said no one should ever disable the paging file. However, seeing as he's already using 1.2 gigs of system memory with a 2 gig page file (and was having problems with memory), I thought it unwise to disable the paging file.

BlueRaja is right. Turning off the pagefile wasn't a good idea. Windows reports that I'm low on of memory, so I turned on the pagefile. I'm letting Windows manage my pagefile now.
