my problem...i've a geforce FX go (chip=250mhz dont say that i shouldn't oc it

and the sliderrange only go to 250 mhz...
powerstrip dont work...if i set the clock in powerstrip higher, the clock for nvidia driver dont change (and benchmarks dont have a higher value)
is there a way to manualy set the clock in registry or any .ini file for detonator driver?
i tried some versions of detonator 44.xx and 45.xx
