I just bought a i5-6600k for my new build that has a MSI z170a gaming m5 motherboard. Does anyone know how to overclock the integrated graphics for my CPU? I have tried changing the GT ratio in the BIOS and using Intel Extreme Utility Tool. My problem is that when I overclock too far or even just a little, my computer graphics crashes when I try running a benchmark. I know I need to mess with the volts but I don't know how much I should or need to. In the BIOS, the volts for the graphics is DEFAULT but I don't know what the default is for my CPU's graphics. My CPU isn't overclocked, it's currently running at 3.5ghz. How do I do this?
