When you first start noticing artifacts and other signs of instability add for example 10mV to voltage, if it still not stable add 10mV more BUT if its till not stable get voltage to stock and start decreasing by 10MHz on core and 20 on memory. TThen run program like furmark, unigine valley or 3dmark for around 15-20 minutes, if temperatures are fine and theres no artifacts increase the clocks by 20-30MHz on core and lets say 50MHz on memory and repeat the procedure. 970 overclocks quite well so they dont have to be small but I at first I would go for around 100MHz on Core and 200 on memory. Most OC guides will advice to do it in smaller sstages for safety.
I wouldnt go as far as nate with increasing it so much at first.
Second thing is power limit, if you really want to overclock you increase it to the max which is 120%.Īnd now about core and memory clock. I didnt get any help in my topic about my 970 Strix problems and ended up rmaing the card so maybe I can advice someone else.įirst of all my card that is under warranty now is 970 Strix OC, I am 100% certain you could add more voltage, all you had to do in Afterburner is to go to options and check "enable voltage control" and then slider in main windows is active so you can increase it, I think you could do around 37mV more than standard voltage but I wouldnt go for more than 10-20mV.
