Virtual Memory

Windows XP supports up to 4 GB RAM. The limiting factor
is the amount of memory your motherboard is designed to support.
 
What do you call virtual memory?
Paging file? Paging file is not virtual memory and virtual memory is not
paging file.

In any case, the answer is NO.
in 32-bit WinXP, maximum ammount of virtual memory PER PROCESS is 2GB by
default. (with 2GB reserved for OS)
Right now, I have 39 active processes running, so the max potential total of
virtual memory availible is:
39x2+2(OS kernel)=80GB

(Win XP 32-bit supports up to 16 paging files each up to 4GB in size. Again,
it's not virtual memory)

I'm asking because I was using 1 Gig of RAM. One of my 512 sticks went
bad so I tried to bump up my virtual memory to help my performance in games
until I can replace the 512. Unfortunately, I can't raise my VM above 1536
Megs.
Would tweaking the paging file help with this at all? If so, where do
you go to access this?

Virtual Memory in Windows XP actually refers to the sum of the
Physical RAM and the Paging File(s). The maximum would therefore be
something in the area of 68 gb, provided you had 16 hard drives each
with a 4 gb paging file plus 4 gb of RAM.

What problem are you encountering with virtual memory? See the

*Sight*
again: paging file is not virtual memory (The description Windows gives you
is way oversimplified). Paging file in loose terms is more like a container
(dispite being a file) / storage that is employed by virtual memory
management to store pages (of modified data) that do not belong in physical
memory (RAM) at the moment and are not backed up by other means (such as
code and data .exe, .dll, mapped file and so on)
Doubt that increasing paging file size would change *performance* in games
(from what you posted I'd guess it's more likely due to loosing DDR which
required 2 *sticks* of RAM), but, if that's what you want to do, here you
go:
WinKey+Pause/Break (or right click 'My Computer' | Properties) | Advanced
Tab | click on 'settings' under 'Performance' | Advanced | under 'Vrtual
memory' click "change', adjust paging file size as desired. Increasing the
size doesn't require re-boot.
 
Well, let's say it's a process of translating / mapping physical memory
pages into virtual address space done by hardware and software.
