thanks for your reply regarding ram.

i need more than 2gig for multiple individual progs that i use at the same time .

virtual musical instruments sequencers and mixers ..all of which are stand alone programs. they divore memory. i would love to go xp64 but many of these can only be run in xp32

at the mome i get about 1500mb (windows eats the 500mb) i heard of this boot configuration that alows xp to see 3gigs..might give it a try on a test partition.
also i have a couple sticks of 667mhz ram, i might mix them with my dominator 1066 pc-8500 (clock them all down to 667 and see if 4 modules helps)
i sooo envy you guys on 64bits with water cooling haha peace
