Hey guys
question for ya. Can you overclock a card, and get a stable overclock. Then later on benchmark it again and have it fail? I overclocked my sapphire radeon hd7970 oc with boost to:
1200ghz
1500 mem
20+ board power
1.25 volts
custom fan profile
and i never exceeded 65 degrees.
I scored a 7600-something on 3d mark.

I ran 3d mark yesterday, and during the cloud atlas test i kept getting weird color triangles and flickering colors as soon as the atlas engines came into the picture. This pattern continued for the remainder of the tests. So as i began to panic a little bit, i dial the overclock down to 1100ghz and 1450 mem. Same thing. Didnt go away till i dropped it all the way down to the stock overclock. Weird thing is, i have been haveing no problems while gameing. So out of curiosity, i put it back to what i had, and just played bf4.
No issues or flicker at all. Should I Leave it alone? Or dial it back? I'm getting a solid 60fps in bf4 90% of the time. Hate to have to lose it.
