Thank you for restoring my faith in humanity. This boosted my only 1080 from 26MH/s to 37Mh/s with Max mem OC in MSI Afterburner. My Linux machines with more than 1 GPU have 1070s on them so this obviously doesn't apply.

Details for everyone with similar GPU:
Core Voltage: Default
Power limit: 60% (can be lower without affecting hash rate)
Temp (gets adjusted with Power limit): 67
Core: -100 (could be lower but I use the machine also while mining)
Mem: +1000
Fan: Auto (sits on 41% when temp is 60 deg C)

Like my voluntary donation to CHFAST for ethminer at Github... I made donations here too - the donation is not for the tool but for the gesture and the fact that it wasn't embedded as a dev fee. Thank you for making this an option rather than a dev fee that runs inside the application (which is just pure evil BTW and yes... there is a BIG difference between taking fee and accepting donations). I am looking at you Claymore and EWBF. Yeah... you know it.
