[Problem] Artifacting after overclocking the CPU?

[iamdarkyoshi]

So I wanted to see what my 3930k can do with such a massive cooling loop. So I went into the bios, though lets just try the Gamers' OC preset. It looked to me like it was going to push 1.4v into it, and a max single core clock of 4.7 and a max all core of 4.4 (I think) base clock was left alone. I edited the settings a bit, I changed the voltage to 1.35v and rebooted. I ran a benchmark and my CPU seemed to do fine, max temps around 65, and no crashes, hangs, or decreases in performance. But then I looked at my right monitor, the secondary one. This one uses DVI and is connected to my 390x, and so is my main one, but my main one uses HDMI so I can get 75hz out of it. But the DVI monitor was artifacting on certain colors on my desktop. Certain colors were red. 

 

Why? The base clock was not touched, and the GPU is and was running at stock clock speeds. I set everything back to default and the artifacting is gone.

Sounds like the CPU is not stable. Had the same issue and had to step it back 100MHz
