144 hz monitor flickers on overdrive

[Salar Sharif]

I have a r9280x with latest drivers and when i change anything in AMD overdrive section (power to memory to etc) my monitor starts flickering and screen starts tearing at 144 hz. When i go down to 120hz everything goes back to normal. What seems to be the problem? Is there a fix?
My monitor is Asus KG240

Could be your video card can't handle any overclocking when running at 144hz.
