Hi there I recently installed 6gb of ram to my Macpro 2,8. But for some reason windows cant see more than 2gigs, i also upgrade my mac book pro memory to 4gigs, and win xp pro can see 3 of theme (as i was told) Why mac pro win xp sees only 2 out of 6? Is anyone have any suggestion ?? Thanx in advance for any response PS i heard that this \3gb switch on xp doesnt do much.
