I turned down the OC...Im going to see if it stabilizes if not ill turn off OC and see what happens....*crosses fingers*
You can see from the tests above, your TDP is more important than OC.
I'm running my own little test with my 5 rigs - 26 1070Ti's Seeing the difference between 75%, no OC; 75% +150+200; and 85%,+150,+200. In each case I'm running 12hours and looking at the Avg Hash Rate from the mining pool (Virtopia). So far at 75% - OC added almost no increase. 85% is half way through and is up slightly. But it doesn't look like the extra electrical draw and ware/tear on the GPU is going to be worth the small increase. I'll see in a few hours.
