I was just playing around on Ramseeker.com and found 2 companies that appear to be supplying 1Ghz Ram Chips for the 1Ghz Titanium Powerbooks that take the PC133 Ram. Of course Apple officially sets the Ram limitations at 1Gig, but was that because noone sold RAM in a configuration, at the time, that would allow more than that? Has anyone tried to put 2 of the 1Gig ram chips in a Titanium yet? I'd be curious to know. Thanks. John Belen
