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

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.
Not if your systems runs dual channel mode.

You could also install two 1 GB memory sticks and two 512 MB memory
sticks and keep the dual channel and have 3 GB of memory. I did this as
I started with the two 512 MB memory sticks, but for a new build I don't
think I would do it that way.
yeah , either way. But with pairs of 1 GB chips at the sweet spot in price, it
doesnt make sense to buy (2) 512MB chips, when many times (2) 1GB chips are
cheaper.
