If it switches off in OCCT at 1.187mV it is a 1.050mV card.
I pull max of 1.148mV at a target voltage of 1.174 in games but I think it would pull much more in OCCT
That's why its turning off, its going above 0.125 over default volts.
I'm going to answer my own question by turning my voltage to slightly higher than 0.125mV targeted and see if my max voltage in game goes up without turning my GPU off.
EDIT: going from a targeted 1.174mV to 1.181mV I now get 1.154 max voltage in game and it doesn't switch off, As long as i don't run stress tests I may have netted another 0.027mV or so. Now its just the question of is it safe to run this 24/7. Although it comes to mind that if it doesn't increase the average voltage there is not much point.
