Great card you have there! Good old silicon lottery! Mine is 70% ASIC! Can get around 1470Mhz on the core but it was crashing the drivers! Settled for 1270MHz on the core (+17) and 2000MHz on the VRAM (+390) very stable for me, and a nice increase in fps! Fan profile of 75%, stock voltage and a 110% Power boost. The card will hit around 1459MHz on the core! Max temp is 57oC! They are great cards!
