I know that there have been many different threads about this but I haven't found a definitive answer. So... Is 8 or 6 gigs possible in the 2.4 uMBP? I'm almost positive that 8 gigs isn't, but I've heard mixed results about 6 gigs. Some say it's stable, some say it's perfectly fine. Anybody out there with a 2.4 with more then 4 gigs?
