Well i'm really confused here !!
I just upgraded my laptop to 8GB of RAM and there is no difference in After Effects. When it first launches, it writes "2% used of 4GB" but I have installed 8GB and when i go to "My Computer" i can see 8GB !!
I am using AE CS4 and i don't think i'm gonna install the CS5 because all my plugins are 32bit and i'm not gonna pay a fortune to upgrade them to 64.
Anyway i can't know why AE hasn't improved yet, i put multi processing on, i have 4 cores, left 2GB of RAM for other apps and put 2GB min allocation per CPU, and CPU's left for other apps "1".
Is the reason that AE CS4 that i have is 32bit?? or my configuration is wrong ?
Appreciate any help i can get.
Thank you

Did you do a clean install?
Meaning that you backed up everything on the laptop's hard drive -- twice -- for safety, then uninstalled the software, plugins and OS, and Installed the new OS and reinstalled the software and plugins?

I didn't really understand your point Dave, do you mean that 32bit plugins work on AE CS5 but I didn't install them the right way ?
Because I already have the CS4 workin properly with all the plugins but my problem is with the RAM. Plus I already tried CS5 before adding the RAM but no plugin worked for me.
I think that Roland is right, since CS4 is 32bit it can only read 4GB of RAM.
Anyway thanks for the help.

I believe that the 32bit application can only 'see' 4GB of RAM.

[Roland R. Kahlenberg] "I believe that the 32bit application can only 'see' 4GB of RAM."

True! With AE CS5, a single instance of AE could see all the RAM in the system.

AE's multiprocessing sidesteps this limitation by launching multiple instances of the AE renderer at the same time. Each instance works on its own frame and requires its own RAM, but no one process will ever "see" more than 4 GB.

When you consider system overhead, 8 GB of RAM is not a lot to feed four instances of the renderer. Depending on your content, your render times may actually improve by using fewer cores, each with more RAM available, than by using more cores with less RAM.

I should clarify this -- with AE CS4, which is 32-bit, no process will ever "see" more than 4 GB.

If you upgraded to CS5, which is 64-bit, that limitation goes away for both the main application as well as background renderer instances.

There's lots of detail here:
