Hi guys, I need a quick advice, please

Im trying to mine with nicehash but I'm new to it.
I want to mine cryptonight so nicehash software makes me run sgminer gm.

How can I set core clock, memory clock and most importantly the voltages??

I've always mined eth with claymore(standalone) and there in the bat file I can set all I want.
I did not use afterburner because I usually mine at 0.85v and afterburner did not let me go so low.


Can I do the same with nicehash that runs sgminer, is there a bat file or a way to set up the values that I want?

Thanks
