[G4] Re: RAM Question-G4Ever

[John Niven]

There are physical and software restrictions.

Earlier G4's (AGP, Gigabit) have four ram slots, so
nowadays you could put in 2Gb, but only if you use
osx. os9 had a 1.5Gb s/w limit.

Later G4's only had 3 ram slots. So using 3 X 512Mb
dimms would mean a limit of 1.5Gb. I don't know if you
could put bigger dimms in, but that would limit you to
3Gb I would have thought.

I find 1Gb is enough. In the classic days a speed-up
technique was to add more memory and turn off virtual
memory (hard drive based). You cannot do that with
OSX. Maybe it does it automatically?
