Video memory on 7300LE

[SilentLexx]

Why nvidia-settings view 512MB of video memory, when I have only 256mb?

this can not be a cause system lockups?

The amount of video displayed is the overall amount of memory available to the GPU, not just the on-board video memory. Please see the corresponding nvidia-settings help page for more information. As to the lockups, are you using the 169.04 driver? If not and the installed driver version is 100.14.11 or later, you are likely experiencing a known stability problem resolved in the 169.04 BETA driver release.

I'm use 169.04 and continue have experience with stability (it's strange!)
Now I try use with 'idle=poll'... 1 hour work fine. If lockups come back, I write here about that.

Lockup come back, again, even on 169.04!
What to do??? Help me please ((
