It can access and use considerably more than 2 Gig of system

benefit from over 2Gig system RAM with XP32 but there are
exceptions, and what you want to do is one of those exceptions. In
terms of pure physical OS limitations, XP32 and Vista32 reserve
memory address space above 3.25Gig for physical mapping of devices
and the like (a 512Mb video card for example) and any RAM above
the 3.2 Gig level is mapped by the OS and essentially unavailable
for the OS to load itself into and for programs to
execute....however you still gain over 1Gig of usable RAM by going
to 4Gig and when handling very large files in video editing it
really makes a noticeable difference. When the files you are
editing are in the multigigabyte size, having a full 3.2Gig of RAM
usable by the OS and the editing app is desirable.
Wouldn't 3 GB RAM be almost as good? If I understood your
explanation correctly, you're saying that anything over 3.2 GB
will be wasted on an XP32 system. It seems like a waste of money
to install a 4th gig of RAM just to get an extra 200 MB of useable
memory.
Increments of 2 same type modules is probably better.
