extra) Testing different voltage offset values and writing down miner performance results

...

Please notice that these power consumption results are measured power at wall,
so the power supply power efficiency also has an effect in the result.

Voltage offset value    Hash rate (Th/s)    Power consumption (W)    Power efficiency (J per Gh/s)    
-2  11.2311950.1064
-1  11.2112220.1090
0  11.3612490.1099
+1  11.3912950.1137

...

So the -2 setting is  very low .1064 per gh. At the wall.

This is better then the s-9

The 841 May do 0.0975 at the wall.
