Methods deal with the problem of "out of memory" ?

1. If "out of memory" occurred, is it helpful if I select the Out-of-core check box, and increase the number of In-core memory (MB) to fix this error?
2. If this method can work, what is the uplimite of the number of In-core memory (MB)? the computer's internal memory (for example, if my computer's internal memory is 2GB, then the uplimite of the number of In-core memory is 2GB)?
3. How many kinds of methods are there to deal with the problem of "out of memory"
Thank you!

Hi
I use two methods:
1) simplify the model (use 2D, symmetries, simplified physics from domains to "shell" boundary conditions ...
2) got a new PC/WS with plenty RAM (for the moment)
if you are "just" at the limit on do not want to test 1 or 2, you can spend (loose?) some time trying
a) use iterative solvers instead of direct ones
b) run in server client mode

Good luck
