you can downgrade the video drivers as they might hold the overclock limits...either way I would not recommend overclocking laptops as they are simply not designed for that with limited airlow inside having all the hardware sandwitched inside
Hey your answer actually worked. My GFX card drivers actually unlocked the overclocking on MSI afterburner. Thanks for you intel. BTW my card only gets around 80C completely MAXED out with MSI burn in test. So my temps are great.
