What is important is accepted hash rate by the pool.
The correct formula for hw errors is "hw / (hw + diffa + diffr)." Should be 1% or under normally. I have a few that get zero HW at normal clocks and a few that get 1% or so, but I don't notice a difference in delivered hash rate. In fact my most productive unit (by only a small margin though) is the one with the most hw errors. All are running at stock clocks. |
