It depends on the card, every one is different. For me I used msi afterburner and HIS iTurbo. For the main card I use I set the voltage to 1200 MV and 20% card voltage. The core clock I set to 1200 MHz and didn't touch memory clock, too unstable for my taste.
The best way to do it is search for a good voltage for your card set that then increase your core clock by 20MHz until OCCT or furmark crashes it then reset to the last stable clock. Do the same thing for memory just with 10MHz increases.
