Turbulence running out of memory

[PEEJAE]

I'm on a MAC w/16 gigs of RAM
I'm in a 1920x1080 AE comp with 1052 frames.
when i hit the restart button, it gets to about frame 51
and i get "ran out of memory" error.
how can this be fixed?

At high resolutions you should only simulate the region that will contain smoke to speed it up. That is, create a smaller composition that you bring into the full frame and only simulate the small comp. This will also speed up the simulation a lot.
Since CS4 is 32Bit only, it cannot use all of your RAM. The upcoming CS5 version of Turbulence.2D will support to use all of your RAM.

Right, i get what ur saying.
but the effect that i'm doing is tracking an object across the entire frame of the HD region...

Maybe you can strip all other aspects from the project file to save memory, create only the simulation and then bring it back in as a rendered movie into the main project.
Also try reducing the cache size parameter to save memory.
