nothing hangs though, hash rate just drops on certain boxes , these are newer cards rx 470s and 570s 580s
These are not related to app restarts , actually a restart tends to fix the issue. Its something with these miners , genoli minder does not do this as far as i know
Do you dual mine? Or you used to and they are older cards? Are they overclocked to the maximum?
Genoil performs much less than either of the miners we are discussing so the demand on the card would be naturally much less.
