Doubt about overclock GTX 1060 6GB trough MSI Afterburner

[rubens2009]

Hello guys.

I'm starting to mine now, I bought my first badge and did a basic overclocking on it by the Afterburner and I'd like your opinion.

VGA: Galax GTX1060 6GB model 60NRH7DSL9OC

Stock:
Core v: none
Power Limit: 100
Core Clock: +0
Memory Clock: +0
Fan Speed: auto

Mining: 17-18 MHS

Overclock:
Core v: none(no change)
Power Limit: 100(no change)
Core Clock: +0(no change)
Memory Clock: +800
Fan Speed: 75%(63º C) / 95%(60º C) / 100%(58º C)

Mining: 20-23 MHS

Increasing only the memory clock hears an interesting gain, but can leaving this way cause a problem or drastically reduce the life of the board? I bought it yesterday(18/06/17) and started mining today.

Feel free to state your opinions or leave a tip.
