Not sure about the 1060 but I got an extra 125mhz on the core and 700mhz on the ram on my 1070, test with furmark for 2-5 mins until temp maxes out to make sure it's stable, if I push it to 144 core it crashes freezing the computer, if I push the ram past 760 it causes the screen to become randomly colored and pixellated, that is your warning that you've reached your limit so restart and back it down a few mhz and try running furmark again for a couple mins to test for stability.
