    Why is the M570TU using "shared memory"?

    My 9800M GTX has 1GB of DDR3 RAM and for some reason my M570TU based notebook is using shared memory.

    Are there any real advantages/disadvantages of having shared memory? I mean 1GB should be enough, no?

    How can shared memory be disabled, I can't seem to find an option in the BIOS?

    shared memory is much slower than the discrete VRAM. of course the GPU will first fill up its own RAM, and then start using shared memory. mind you, i don't think that will happen very often, seeing how the GPU has 1Gb :)

    So it is not like we are talking about reserved memory or anything like this? Because on my system my GPU has 1GB DDR3 and 2GB DDR3 that is uses from the system (according to the NVidia control panel).
