ok, bios flash succesful using freedos, but I can't overclock more than 810mhz (405mhz stock speed), nvidia inspector show a grayed shader speed tab instead of boost speed... see attachment.... my 3dMark 11 scores were lower than when I ran it on official overclocked 2.13, tried overclocking the p8 state, right click apply clocks and voltage and then apply to all higher p-states but no luck, not enough voltage.. nvidia inspector screenshot: GPU-Z vmodded 2.13 @ stock clock -
