- does anyone determine profitability including power for GPUs without any mods? The % you achieve without mods is about the same here.
I am quite certain that fewer than 0.001% of GPU miners take a soldering iron to their GPUs to improve mining performance.
The biggest gain is a software undervolt...
And none of those mods are necessary to see better than GPU performance per $ spent, at significantly less power. Some people just like to take it to extreme tuning as well.
