10 GB on the Mac Pro in my signature, but I have to admit that I rarely use more than ~5 GB at a time...
Wow! i am surprised at how many people have 8 or more Gigs or memory! I am just bumping mine from 1.5G to 5.5G, but the comments I have heard, is don't expect miracles in performance improvement! If that is the case, why are so many people putting so much memory on their Macs? Games?
Which tool is best to check memory usage?
My powermac is getting pretty old, a pm G4 400, AGP, but acting primarily as a file server it still runs quite well. It even runs Tiger. And it holds a 64mb, a 128 mb, a 256 mb and a 512 mb RAM chips, for a total of ~950 MB (it has been slowly upgraded over the years ). And I still say it is one of the most well-made computers in existence, >8 years old and still going strong.
