Jed i also have a AMD 2400+ with XP it is my main DAW. It runs great, but i had to put two matched sticks of Ram in it 1 gig each. I had 512 to start, the added 1 gig like you and it reverted the machine to single round ram, and i had to remove the 512 to get it to work well, then i went down and got another 1 gig and it runs very strong and smooth.

Make sure that the ram sticks are all the same if you have 1 gig make sure that the speeds match and all that stuff. 1.5 gigs will work fine for things other than audio and midi work which is always a big resource hog!
