Thanks very much for your help voch.

As it turns out, I was doing some browsing earlier and figured out what is going on.

http://everymac.com/systems/apple/i..._g4_1.0_14.html
this is the mac that i got. 1ghz G4 (7457) w/ 128 built in, released oct 2003. 640 max

http://everymac.com/systems/apple/i...4_1.0_14_2.html
this is the 1ghz G4 (7447a) that has 256 built in, released 6 months later when they re-speced the line for 1.25 max and a few other upgrades.


Now that's straightened out, I guess I'm probably stuck with 640mb. I guess it's worth asking one of the techs, though, if that's a hard limit or simply the specs because the 1 gig chips weren't really available yet.

Thanks again
