WTFF? (yeah, two F's)
128 GIGS?
dude, even the most advanced processors can't support 10 Gigs of ram without having compatibility problems.... and it's known that always the hardware is most advanced than the software (y'know, if a programmer makes a code to be tested in a 5 Ghz processor, where would he test it?)
XP was (I think) designed to support up to 4 Gigs of ram. that was ok when XP came out, where most of processors where pentiums of roughly 1.8 GHz with up to 2 Gigs of ram.
and now Vista makes the big jump up to 128 Gigs?????? something might be wrong.....
EDIT: 1- yep, XP was made to adress up to 4 Gigs.
2- if you calculate: 2^32bits == 4 GB. that's ok.
2^64bits == (4 GB)^2 == 16 GB. that's != 128 GB.
