DasHotShot :
You reached max 80c temp. Nothing crashed. Sounds fine.
Not 100% sure on GTX 970 settings. Also what do you mean by you "changed it" regarding the ram?
You may want to stress test it using Furmark or something for a few hours in one go, to make sure it is stable.
by changing it i mean Memory Clock was 7000, i changed it to 8500, and Boost clock was 1000, made it 1350.
Rather than download furmark, cant i jsut play battlefield hardline for few hours or stress test would be better?Lastly, Is it a nice OC overall, nice boost from core clock?
