For an AIM system (G3/4/5) which is essentially Apple h/w, it's 2GB since Apple like to memory-map i/o above that. >I play on a G3 imac with 1GB memory. On CURRENT.

I've not had that much RAM in a G3, but certainly have had 1GB in a number of G4's without problems. I'm guessing it's a VM bug rather than bad memory. Was the component you were building using a lot of VM ? (e.g. KDE) later, Peter.
