My 1070 is a Windforce OC from Gigabyte (altough i wanted the G1 Gaming...). I can adjust the core clock and it is stable until ~+150mhz but when i tried pushing further heaven would give me weird purple graphical glitches, and crashed after a while so that implied that +160v was too much for the stock voltage and i needed to add some more, but it is greyed out and when i try to move the thing on the slider i jsut move around the whole afterburner window. This only happens in MSI Afterburner. I tried OCing in Gigabyte's software where it let me adjust core voltages, i just dislike using it because it is obnoxious and it only lets me change voltage in % (wtf), and that cannot be changed in the settings, plus the system monitor part sucks as well. I haven't tried other software, i want afterburner to work, or if there is a better alternative please inform me about it.
