AfterEffects CS5 showing only 4 gig of RAM
Just installed Windows 7 64-bit and AfterEffects CS5. Did a test render on an existing project and the Render Queue shows that it is only addressing 4gig of RAM. The system has 8.
Is there a setting that needs to be changed, even in CS5, in order to address more than 4gig of RAM? I thought this might be a common issue, but I googled and scanned this forum and couldn’t find much.
P.S. Are there any settings that should be tweaked for multi-processing, multi-threading, etc?

If your computer has more than one processor or core you need to enable multiprocessing in After Effects Preferences> Memory and Mutliprocessing.
However, 8Gb of RAM is not really sufficient to take advantage of multiprocessing since each process can access 3Gb.

AE CS5 on a 64-bit system does away with those old memory limitations.
I’d suggest looking in Preferences > Memory & Multiprocessing, and checking the amount of RAM reserved for other applications.
Brian’s link is the best place to start on memory settings. That said, 8 GB of RAM is not a lot for AE, especially once you take multiprocessing into account. I’d say you’ll get better performance leaving a little bit of RAM unused than you would maxing everything out and forcing your system to swap during render.
