Greetings!

I'm starting OC my cards, one by one. I've a 1070 Palit SJS and I'm mining Zcash on nanopool and sometimes use nicehash for the most profitable coin.
Now, at stock settings, it reach 440sol/s and 40.1 MH/s on Nicehash.
I would love to increase performance but I don't know what I should modify to rise earnings.

My first profile setting is:
Power Limit: 80%
Temp Limit: 80%
Core Clock: -120MHz
Memory Clock: +800MHz
giving me 471Sol/s

From this point, every slide I move, result in a decrease of the hash per second.
The problem is that I have not understood how this whole process works.

I'm also hoping there are some general settings in order to make my gpu more profitable.
N.B. so far, I'm using just one gpu, the others have to wait the cables to arrives. But I would love to learn this process, so when my hardware arrive, I will be ready to OC them.

Thanks
