Core clock OC sliders maxed out

[Hellpro]

I am trying to overclock my GTX 760m in an Gigabyte P34. I have successfully reached the maximum in all overclocking programs but my gpu has not been working very hard since my temperatures are only 70-72 for short periodes of time. I have tried enabling unofficiall overclocking in afuerburner but it does not do anything. Is there anything that i can do to get higher clockspeeds?

MSI Afterburner enabling unofficial over clocking would be your best bet but you say that didnt work so youre screwed

Oh, ok

I was reading that i culd get it past the GTX 765m clockspeeds but i get about 1 less MHz
