Is it possible to increase the 320M's shared memory?

I'm curious if having some more memory dedicated to the GPU will help out with my dual monitor setup. Despite having 8GB, the 320M still only seems to be taking 256mb. Is anyone aware of third-party utilities that will shift more of the system ram to the graphics?

It does not increase as with the Intel HD as far I know.

in another thread, someone said it expands to 512 MB with 8 GB of RAM...you sure you're not seeing 256 MB for each monitor?

On my 2009 MBP with the older but related 9400M, even installing 8GB of RAM I only got 256MB video RAM.

The real question is though, what do you need 512MB of video RAM for? The 320M is pretty weak at 3D graphics, and anything legitimately requiring 512MB video RAM probably isn't going to run well on a 320M anyways.

Activity Monitor shows 7.75GB of system memory available, and System Profiler says the 320M is using 256MB.

I'm not sure myself if it would help or not; I was just curious if the extra vram would help make the GUI (Expose, etc.) run a little better with a dual-display setup.
