Gpu overclocking

Can someone point me in the right direction here things have changed over the past few years and I am a little lost. I am having trouble understanding power limits. Also in the past if you went too far the graphics driver would just reset, I am experiencing a black screen even on reboot dont even see bios. I had to take my old gpu and boot with that then put my card back, so after a few attempts I gave up. It is an XFX double dissipation 260x could it be drivers? I even get a black screen just moving the power limit to 20% and leaving the clocks stock, from what I understand that just allows the card to draw more power. I dont think it is a power issue as I have a 600 watt psu. Should I try a fresh reformat? Even doing a light overclock with setting that seems like everyone else gets I am getting a black screen. Also I was at 1200mhz core and 1750mhz ram it was stable ran furmrak for 30 min then cinibench it gave me about 11 fps more on cinibench then I got a black screen randomly. I want to figure it out because the overclock nets me about 20% gains. I tried msi afterburner also but the voltage options are not available and from what i understand power limit is not the same thing as core voltage.

The black screening might be because you didn't add enough voltage to the GPU. Was the 1200mhz clock speed the speed before or after you applied the overclock?

After but its a speed that many others have got and I dont see a way to adjust voltage. And my test card for fixing computers my r5 230 if you go too far the drivers just crash and it resets in a few seconds, this the black screen is permanent a reboot i cant even get to my bios. Is it because i may have the old drivers for the 230 still somewhere after the uninstall? The behavior is really weird any tools I should try I have read that using catalyst control center is not recommended.
