I have a gtx 1080, and I have found that power limit -10% does some effect as undervoltage by 10%, but when I use power limit some graphs looks really scarry (temparature in both cases goes -5 degrees)
and GPU no load limit, GPU power and GPU Core Clock graphs also unstable.
When I use undervoltage, all graphs seems like a line.
What approach is better for life my videocard? Is anyone have information about this case? What happens with GPU in both case and how dangerouse undervoltage can be?
Thanks in advance, Andrei!
