I have a Titanium 15" Ghz, Superdrive 12/2002. According to Everymac.com and elsewhere it has a Max Ram of 1Gig, which I have. At Ramseeker, there is a vendor that proclaims to make a 1Gig Ram chip for it. Is the 1Gig Ram a limit of the motherboard, or is it just that noone had 1Gig chips at the time of production? Can I put 2 1Gig Ram chips in this machine? Thanks John Belen Lansing Macintosh Users Group. www.lamalug.org
