When I first installed Vista, I had 4gig, and the ReadyCache was constantly running it down to 0megs free. And that was fine - but I figured, hey, if ReadyCache will use that much RAM, it should be able to cache even more if I add more RAM. Not really so. ReadyCache typically hovers at around 4gigs, leaving a lot of RAM free. -- ltwally
