Heaven was fully stable at 1.231v too, for an hour, but got up to 88C, with room temp at idk, 86 degrees fahrenheit).

So the lower Vid cards can't take as much voltage, but clock better on less?
Falkentyne how you guys finding your vid . on my card i start artifact after 1.250 volts , 1.3 is just crash city , but i havent really work on my core with less volts so that might be the ticket , to keep from artifact so early on , I would for sure like to hit 1300mhz , but a stable 1200 seems to be the spot with out better cooling
