System One and System Two have PageFile set at 2046mb. (I tried reducing the
page file in System Two. No change to reported values in the task manager.)

boot.ini files in both systems no /3gb or /pae switches. Everything has
been directed by the OS, no hacks. I tried the /3gb hack on xp pro, but
nothing changed.

I've researched the 4GB ram issue in 32bit XP, but I still can't find a
clear answer to my concern. I just want to make sure that xp pro is actually
utilizing the physical memory over 2gb. I somewhat understand the nuances of
how the OS maps the memory and uses the page file. My only real concern is
just some evidence that System Two is actually "seeing" (and using) the
physical ram above 2gb.

Any suggestions? Is this just a reporting issue with the OS?

Thanks.
