I have a gtx1070 Asus Turbo and I was changing the GPU clock some days ago, just 100ghz up of the value it was set. Nothing dangerous and the temperature did not went more than 82degrees, but since I did that while playing lol or overwatch I see small lines distorionating the image that should be behind them going up and down the screen, I use a 2560x1440 minitor at 60hz and I experience this problem since I changed this. I changed the settings back to normal but still the issue and I can't find the answer to this and why that setting made all this, does that mean that I can not overclock the GPU? How can I fix it? Why it did not happened before? How can I overclock it? I'm new in overclocking things or in those problems so any help would be appreciated. Thank you all.
