FIRST you need to learn to ignore the ram usage in Vista. Is is
different than any OS before it. The more free ram you have means that
Vista is not doing its job correctly. Ram is MUCH faster than
harddrive speeds, therefore Vista is making use of the fast stuff and
leaving the slower drives for XP.
Second 32 bit systems have trouble with more than 3 gig of ram, just
the way it is. Same system, 32 bit versus 64 bit, 32 bit has issues.
