I've got 3 rigs that all report 1.5-1.7 locally but only get 3.9 on any pool. Anyone else experience this?
Thus far, I have only seen GMaxwell say that he can achieve the same hashrate as the interface claims. Everyone else who has posted seems to be in the 1.3-1.45 TH/s range for each unit. I believe Con addressed this already too.
