Before mod my antminer was consuming 348W on the wall on 180GH/s but now it takes only 260W on 165GH/s.

Assuming $0.20/kWh
Without undervolting: Daily $6.04 mined minus $1.67 electricity = $4.37 daily profit
After undervolting: Daily $5.53 mined minus $1.20 electricity = $4.33 daily profit

Right now we are at the point where undervolting starts making sense for those with expensive electricity.
I am one of those. Just want to know the risks before I start doing it.

I read about undervolting CPUs that the only risk is less stability, i.e. it may reboot now and then. I guess for Antminer that a symptom of too low voltage is high HW error. Right?
