never heard that before... a little surprised they're -that-

some pc133 is 'high density', some is 'low density'; afaik the
difference is the # of bits in the refresh counter. low density is
pc100 compatible and as i understood, pc66 also.
speaking of which, i've long known of 256M pc100/133 sticks,
essentially 128M on both sides. but i was recently in a pc store
helping my gf and her son buy a notebook [lenovo] and noticed -512M-
pc100 sticks. didn't get a chance to ask details - anyone know?
