Another thing to note is that you cannot use OpenGL and Multiprocessor rendering at the same time, this is because OpenGL pushes rendering processes over to your video cards' GPU whereas Multiprocessor rendering uses each system processor/core individually to render frames.

To use all 8GB (or 16GB, or 20GB...) on a multi-core computer running a 64-bit operating system (like Mac OS X), use the Render Multiple Frames Simultaneously multiprocessing feature. With this feature, each instance (process) of the 32-bit After Effects application can use the amount of RAM described above.

If you have more questions, please use the After Effects user-to-user forum, which is a much better forum for questions and answers than is a series of comments on a documentation page.

I would like to know the same thing as above I have a PC with 8 GB, Vista 64, is it even possible to use 8 gb even though cs3 programs are 32 bit.
thanks.

I have 8gb of Ram on my 2.66 Dual Core Mac. After Effects shows only 3gb available. Is is possible to use all 8? How is this done? Thanks.

If anyone does not want to upgrade ram but after effects is telling them they have run out of memory when exporting, go edit - preferences - (click on the secret menu) then press purge every 15 frames.

For information on using the /3GB switch with Windows XP, follow the link to Jonas Hummelstrand's website, which is given in the main body of this page: www.adobe.com/go/learn_ae_jonaswindows3gb

If this is not the information that you're looking for, or if you have other questions, please bring them to the Adobe After Effects user-to-user forum, which is generally a better place to ask questions than in LiveDocs comments: http://www.adobeforums.com/webx/.ee6b2fe/

I am using Window XP SP2. How do I increase the amount of available memory for After Effects? Bcdedit seems to be a Vista command.

Thanks

A couple of import things to make a note of:

1. Firstly you should back up the current settings
bcdedit /export "C:\BCDBackup"

NOTE: to restore the previous (saved) settings if there are problems

bcdedit /import "C:\BCDBackup"

2. Take a look at this webpage for a more in depth understanding of the process involved.

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:

For anyone using Vista that wants to use more than 2 gigs of ram in After Effects this is how you do it:

run a command prompt as Administrator and enter the following:
bcdedit /set IncreaseUserVa 3072

A value of 3072 will increase your programs available memory to 3 gigabytes. If you want more than that adjust accordingly by multiplying the number of gigs you want to use by 1024 (ie. 4096 for 4 gigs, etc...)

Next run msconfig either from the same command line or by typing msconfig into the run or search fields on the start menu and hitting enter.

Go into the advanced options on the boot tab. In there you will find an option for maximum memory, set this to the same value you entered at the command line. Additionally if you have a multi processor or dual/quad core machine you can increase the number of processors used on this screen.

Hit ok to close the advanced options and then check off make all boot settings permanent and hit ok again to close msconfig. You will need to restart. After this you will see an increased amount of ram available in the After Effects memory settings.

As a cautionary note, if any of these steps seem confusing or difficult for you then you probably shouldn't try this. There are reasons that these settings are protected from casual adjustment which I would suggest researching before messing around.
