For a few months now, I've had one memory slot bad in my G4. I know there was that recall but my G4 doesn't have the right serial number range. I was told Apple charges a flat rate of $310 to fix anything. I went into the Apple store to see if it was still the same price. One guy told me that "Since they make bigger ram now, you can just put one 2 gig chip in one slot. It'll save you money." Since I've been in IT for 9+ years, I think he's an idiot. But I thought I'd ask you guys. I know the G4 supports up to 2 gigs, but can I put just one 2 gig chip in?
