I updated my Throttle script to support changing the
MaxNumberOfProcesses preference easy within an embed-able panel. The
script also allows changing the "Allow Idle Rendering" pref which allows AE
to continue rendering the Comp frame if you switch away to another
application. You can get Throttle here:

You cannot use the Render Multiple Frames Simultaneously multiprocessing feature while also using OpenGL to render RAM previews or render for final output. The Render Multiple Frames Simultaneously feature works by using background processes on multiple CPU processor cores to render frames. OpenGL processing uses the GPU.

1.Quit After Effects.
2.Open the After Effects text preferences file, Adobe After Effects 8.0 Prefs.txt, located in the following folder:
Mac OS: Users//Library/Preferences/Adobe/After Effects/8.0
Windows XP: C:\Documents and Settings\\Application Data\Adobe\After Effects\8.0
Windows Vista: C:\Users\\AppData\Roaming\Adobe\After Effects\8.0
3.Find the ['MP'] section.
4.Change the "MaxNumberOfProcesses" value to "6".
5.Save and close the preferences file.

In 8.0.2 or higher:

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.

The Render Multiple Frames Simultaneously mode works best with 2GB of RAM for each processor core. If you have 8GB of RAM and eight cores (as with a computer with four dual-core chips), you may get better results using only four of the processor cores. For instructions on how to restrict the number of cores used for multiprocessing in Render Multiple Frames Simultaneously mode, see the Technical Support Knowledgebase:
