Yet another Mac: Ram / Multiprocessing question… Please
MacPro: 2.8ghz dual 4 core; 14gb Ram, (seen in System Profiler); AE CS3 8.0.2
Everything is fully updated.I know this has been asked before, but I am thick, and not the sharpest tool in the shed.
In AE memory prefs, it says I have only 3gb ram. (Why AE still doesn’t see the RAM, I have no idea…)
Now, if I set Maximum Memory Usage to 50% = 1.5gb, and
if I set Maximum RAM Cache Size to 50% = 1.5gb, and
in Multiprocessing Prefs, I check: Render Multiple Frames Simultaneously, (confirming an additional 7 processors will be used.)Then, even though AE “says,” it only saw 3gb Ram total,
It will still use 8 cores x 1.5gb a piece = 12gb used by AE, leaving me 2gb free for other use?
Is there anything else I need to do?
Is there any way to get AE to actually recognize the RAM, or, more importantly, is there any way to confirm it is working?
I really appreciate the help…

I should have also mentioned I am also running OSX 10.5.2, also fully updated.

Open up Activity Monitor while doing a render. It’s located in Applications > Utilities > Activity Monitor. There should be several ‘aeselflink’ or ‘aerender’ (i forget what its called exactly) processes running during a render that will each tell you how much RAM their using.
Your setup sounds correct, aside from the abnormally low Maximum Memory Usage.
