I watched this video to overclock my gpu,
https://www.youtube.com/watch?v=rqY9KNlTkRA&pp=ygUXZ3QxMDMwIG1zaSBvdmVyY2xvY2tpbmc%3D
I Followed all the steps and my DISPLAY started flickering once i hit apply, i was not able to turn on or off any thing using keyboard or my mouse, and i forced shutdown my pc by holding the button on my CPU.
I waited and then turned it on, it worked fine and the changes in my afterburner were back to original settings, and FAILED to overclock my GPU.
this is how my Display flickered when i hit apply
I did try with just one display connected to PC, i dont know what else to do. Help if somebody has an idea on how to overclock my GPU
