Virtual memory limit

Is there a limit to how much virtual memory a single process can address
running under XP Pro? I've been told that it is 2GB but hoped to get
verification.

Virtual memory max would be determined by the amount of the page file
and amount of ram installed.

No offense, but that doesn't answer the poster's question. I'd
like to know, too. When you don't have an answer, don't bother
answering.

Virtual? The address space limit is 2 gig. How much of it is "virtual"
is rather immaterial.

Actually the OP's question as written doesn't make sense, so the answers
are going to be based on what the reader thinks the poster was
attempting to ask. And as a tagalong poster, you seem to be just as
confused as the OP, but with an attitude to boot. BTW the address space
is 2 gig.

Yes Bob. Virtual memory is the "effective" memory accessible on a computer.
It often is a combination of RAM (physical memory) and pagefile (memory
segments that have been written to disk). I chose the term "virtual memory"
to make a distinction from physical memory, which many people assume, when
one simply uses the term memory. I hope this clears up the confusion for
you.

The basic memory model of the architecture sets 2 GB as the Application
area (plus one each for System and 'Shared')

2 GB of application VM = some pages in physical memory, some page file usage
and some DLL functions reloaded as needed.

The page file is NOT what it appears to be, it is several things.
The page file can ve hugh, 16 TB or some unreachable number.

Think of Physical memory as a high speed cach buffer for all VM on the page
file and active DLL's and active DATA.

To tune the page file (for most users) is very simple (512MB or 1024 MB or
1,536 MB). Pick the one that is > than your Physical memeory size and forget
about it.
