after many hours, i have some problem with 2.7b :

- after many lost internet connection, it lose -powlim, -cclock, -cvddc, -mclock, -mvddc setting.
- fanmax 95 but it's going to 99 (ok temp is to hot, but i have fixed a limit)
- after many reboot for solve the first problem, it's always same. my setting isn't apply but app show at start it want apply my setting.
- after all of this, he make # before all line of this setting (-powlim, -cclock, -cvddc, -mclock, -mvddc, -fanmin, -fanmax),  but app try to apply always the previous setting.

come back to 2.6, and work perfectly.
