Its seem when i deaktivate the zero RPM it will dont crash at time.
I have delet all drivers, update, downgrade and clean with DDU.
The only thing i didnt can make is to restor a older point of the system. so i dont have set one.
EDIT: After i have played a littel bit with manual settings and put zero RPM on again, it dont take the settings. Its seems that the wattman hold the settings in ther from previus. or let say the settings are freezt in the regestrie i thing. its not logical!
After i install the driver new zero RPM works again, but when the GPU hits the 48 - 49° the System Shut down!
