Fuzzy horizontal lines after overclock.

andrewsmc · Mar 20, 2013

So as I am trying to overclock my CPU and I will get fuzzy horizontal lines when booting into windows. Is there a simple fix to this, or is it just trial and error? I have tried just about everything to my knowledge and cant seem to find a setting/adjustment to fix it. I have tried adjusting all kinds of voltages and settings. System specs are to the left. :toast:

Thanks!

Edit: I am also using onboard video for right now.

Using DVI/HDMI or VGA? Is the onboard video unstable anywhere else besides the Starting Windows screen? Are you overclocking your RAM at all or using lower than rated timings?

Is there no way to set your graphics core to a fixed freq? it is scaling with your CPU oc

DVI, not unstable anywhere else. I have set my ram to factory timing and voltage is all.

Is it possible your pciex bus speed is set to auto and over clocking with your cpu causing instability set it manually to 100
