980m problem.

Hi.

I'm having a big problem with my 980M as it doesn't want to work at full speed. I installed Prema Vbios for the 980M and also latest Bios for the motherboard.

When I start a game or 3dmark it goes to 600-700mhz instead of the 1038mhz.

I'm using 350.12 nvidia driver.
Clevo P170EM. 3740QM.

Any help with this?

Thank you
