Re: Need to add 2 gigs to existing triple channel 6 gigs
vista 64-bit supports alot more than just 8 gigs. off the top of my head, i think it actually supports like 128gigs of ram, some large number like that.
you could buy a 3gig (3x1gig) kit of ram instead.
edit: actually i just checked, it depends on what version of vista you have. only home basic has a limit of 8gigs. which do you have?
