I just want to know value of graphics voltage required to overclock graphics to max.1.5ghz by increasing core multipliers no.to 31 from default 22 ???
The integrated graphics is already optimized and is not meant for user adjustments. As the above poster suggested, get a graphics card and install it on your motherboard.
