Why this message ? Virtual Memory Too Low


It's when an application tries to allocate memory which is larger than the
available physical or virtual memory. It depends on the application, since
it can choose the memory storage between physical, or both physical and
virtual.

Check the virtual memory setting from the System control panel (or press
WIN+Pause). Open the Advanced System Settings. Open the Performance
Settings. On the Advanced tab, click the Change button. Tick/set the topmost
checkbox to let the system manage the virtual memory size.

That would be the Advanced tab, in Windows XP.

The optimal memory size should be 1.5 times your physical RAM. So if
your ram is 2GB then your virtual amount should be 3GB and so you have
5GB to play with. Some would even go for twice the amount to make total
available 6GB in my example of 2GB. I chose 2GB because this is what
most people have on their XP machine. For Windows 10 people normally
have 8GB so it is a good candidate to make it 1.5 times 8GB = 12GB;
Total makes it 20GB.

What were you doing to get this horrible message? It must be very
memory hungry App.

Hey OGER, how's life treating you?

Gibberish. Each process in your machine is allocated a virtual memory
space to run in. For 32-bit machines, that space is 4GB. Half of that
is reserved for the OS, the rest is available for the program.

*Each* process has a 4GB virtual space. Clearly, if you have a lot of
processes and not much physical memory, you're going to use your swap
file a lot, and all that disk access is going to slow down your
computer.

The Windows OS handles the swap file efficiently. I'd guess GoodGuy is
talking about manually setting the size of that file, but I'd let the
OS handle it. I can't think of any reason to restrict the size of the
swap file.

Virtual memory = pagefile (on disk)

https://en.wikipedia.org/wiki/Virtual_memory

Despite articles telling you that you can reduce the pagefile to [near]
zero when you have gobs of system RAM, that causes many programs to fail
or become crippled. For example, video games will often pre-load lots
of textures and object into the pagefile so it is available on demand
instead of having to do file I/O calls to open and read from files on
the disk. Although the pagefile is also on the disk, accessing data
from it is faster than doing file I/O. Many programs want to use
virtual memory. They can make a minimal request which if disallowed
means they fail to load their data and can error, crash, or become
crippled along with asking for a maximum reserve which they might like
to use but might not get depending on the current availability.

https://www.howtogeek.com/126430/htg...ou-disable-it/

You should always have some pagefile space. Even the OS wants some.
Ideally you would set it to the min() of the minimum request by all
programs you run or may run later, including the OS; however, knowing
that minimum value is tough to impossible. Just because the pagefile is
set to, say, a maximum of 6GB doesn't mean it uses it all on the disk.
Depends on how you have the min and max configured for pagefile size.
With gobs of system RAM (4GB really is not gobs of RAM nowadays), some
recommended setting the pagefile to half of the system RAM but that's
just a guess. Could be too much, could be too little, depends on what
you run under that OS. Looks like half is too little for you.

You might have so many progams consuming the pagefile (fixed for its
maximum size) that there is no more space for another program to request
its minimum virtual memory allocation. As for the given example, could
be you are loading a video game but there just isn't enough paging space
left for it to use. No info on what processes were running at the time.

Back in Windows XP, and without knowing what will want to use the
pagefile (other than the OS), the recommendation was to set the pagefile
size to 1.5 times the physical RAM size. You say you have 3.2GB. That
looks like you probably have 4GB of physical system RAM of which the OS
will allocate only up to 3.2GB to user-mode memory space (without
tweaking some OS config which you shouldn't get into). Per the
recommendation, your pagefile should be 6GB. However, that probably
would likely be a waste of disk space unless you are running a program
that wants huge amounts of pagefile space or running multiple programs
with each wanting a large amount of pagefile space. 4GB of pagefile
should be sufficient for you but 2.1GB for pagefile space is only about
half of your system RAM.

Is Windows XP configured to have it determine the size of the pagefile
or did you fix it to a value of 2.1GB?

https://www.geeksinphoenix.com/blog/...indows-XP.aspx

If you set a different minimum and maximum (reserve) size for the
pagefile, it can get fragmented. A trick to prevent fragmenting the
pagefile is to set the minimum and maximum size to the same value. You
then need to delete the current pagefile, defrag, and reboot Windows to
have it create a new 1-fragment pagefile. You could leave the pagefile
configured to let the OS figure out its size. That will result in
fragmentation of the pagefile. You could use a min value to save some
disk space unless needed up to the max value but that causes fragging.
If, say, you wanted 2GB for min and 6GB for max, the difference is 4GB.
If 4GB is so tight on free space for the drive even after cleanup, it's
time to consider getting a newer and bigger drive.

Did you configure just the drive for the OS partition to have a pagefile
or did you split the pagefile across two, or more, drives?

You didn't say WHAT you tried to run that resulted in the "too low"
prompt. Here's an example of software that wants to use the pagefile
and complains if there isn't enough:

Gibberish. Each process in your machine is allocated a virtual memory

[]
This "page file should be x times actual RAM" is something I remember
from the days of Windows 3.1 and typical memory sizes of 4 M (yes, M not
G!). I never understood it even then: to me, the _more_ RAM you have,
the _less_ you're likely to need virtual RAM. There was a slight reason
for it, _if_ you agreed with the following suggestion: that someone who
has x amount of real RAM is likely to _run_ certain types of
application.

As VanguardLH said, it's probably wise to have _some_ virtual RAM in
case of the unexpected, and also to set minimum and maximum to the same
- and delete the previous one - to ensure it is created, and remains,
unfragmented.

Even though nothing in your message appears to be
copied verbatim from your WinXP setup, I'll toss
this one out as an explanation for sudden demand
like that.

Apparently, Windows Media Player can act
as a streaming server, and a video which doesn't
parse properly causes WMP Network Sharing Service
to go nuts and use up 2GB (the process grows until
it cannot ask for any more memory).

http://www.tomshardware.com/answers/...ory-usage.html

Now, if that's not it, perhaps you can share with
us, what's running on the system, and whether those
items are using a lot of RAM or not.

*******

These are some notifications for WinXP:

1) "Windows - Virtual Memory Minimum Too Low"
2) "Windows - Out of Virtual Memory"

Actually, the page file must be at least the same size as the memory
allocated by kernel - which vary accross different system setups. That'll
ensure successful dump when BSOD occured. Otherwise, either the dump would
fail, or the system would crash completely.
