RAM Settings?

New Mac Pro - 8 core - with 10 gig of RAM installed.
Could someone give me a recommendation for the correct RAM settings in preferences? Typically I would run AE by itself, or with PS at the same time.
Occasionally FCP as well.

The defaults should work well for you.
Max Mem Usage: 120%
RAM Cache: 60%
With 10GB of RAM you'll probably want to enable multiprocessing to make the most of your RAM. At the default Memory & Cache settings this should allow you to render using 5 processors (5 frames at once!)

This was in the 'read-me' files for the 8.0.2 upodate
# Multiprocessing performance issues with multi-core machines, especially high-end 8-core hardware. When all 8 cores try to render a complex or memory intensive composition with Render Mutliple Frames Simultaneously, the application can become memory starved if each process has insufficient memory. To remedy this, there is a text preference to control the maximum number of cores that Render Multiple Frames Simultaneously will use. Open the text preference file and look in the ["MP"] section for: "MaxNumberOfProcesses" = "0". "0" is the default setting, which disables this preference setting. For better performance on an 8-core machine with 8GB RAM, for example, change the "0" setting to "4" and save the preference file and restart After Effects. This restricts multiprocessing with RenderMultiple Frames Simultaneously to 4 cores, each getting approximately 2GB of RAM.
# For other performance tips using large dimension or complex compositions, see the "Improve performance" section of After Effects CS3 Help on the Web.
