I have just started to mess around overclocking with my gpu. I noticed the difference in my games now, and it's fantastic and loving the card. But now I have this flicker when OC'd, while watching youtube videos, and even windows media player. When I open new videos on youtube or new video files, I get it constantly. It not during playback, just when initially opening. I disabled hardware acceleration on flash and still get it. When I go back to stock settings, everything on my desktop runs normal, no problems. I am currently using Sapphire Trixx.

Stock
Core: 900mhz
memory: 1200
voltage:1138
Board power: 0%

Overclocked:
core:1050
memory:1450
voltage:1138 (same as stock) - tried at 1050, still still flickered
board power: 20%,

I am trying to limit increasing the voltage when overclocking. By the way I monitor and temps reach the low 60s. I have a feeling there is nothing wrong with my card, just there is some sort of setting that is causing this. I have also unchecked enable overdriver in CCC. I've read the memory clock may be the culprit. Just trying to get more tips and what not.
 


First off, increase your board power to 100%, this allows it to draw the max needed wattage.
