There's a power saving function, who disable the second video card when not in use ( UPLS in register windows ) ... when you are under normal windows operation, the second card is power off ( power saving ) ...
So basically, when you are under windows and just browse internet, only the first gpu will work , when you enter an intensive task ( game or software who need it ) the second gpu will wake up.
By editing the register, you can set UPLS to off, and so both cards are acting //power on, all the time......... ( 157mhz / 300 inidlle and full clock when needed )
