I don't know how successful this is, but apparently you can use a USB memory stick to increase the virtual RAM memory when running XP.
The full instructions can be found here:

(If you click on the button to "View all steps" you may find it easier to follow, as the instructions will then be all on one page).
I haven't tried this myself, (I remembered reading about it some time ago and looked it up again) so as I said at the start, I don't know how well it works but it may be worth a try.
