I was able to increase the hashrate to 2162 hash on each card .
I couldn't be selfish, so I shared these settings,
So that anyone who might be just like me, hoping for income just from this mining system, can make the optimally .

Power will be only 200 watts per card, which is good.

I am in a country where talents are suppressed and fools are in power. Yes Iran
