Its good but the undervolt is not enough, I prefer 0.963v or 1 volt....
For you perhaps but for me it is enough, dropping to a lower voltage on my rig decreases stability and I lose more coins from downtime than I do from achieving the extra 1.5 watt drop at the wall that I could get at 0.963v.
I am not in competition with you to get a lower voltage I am in competition with my rig to get more hash per watt.
