Since upgrading from 10.6 to 11.3 (and now 11.4) my hawaii rigs are having hash rate drops every so often. About 5-7% drop lasting for around 2 minutes before going back to normal for about 10-15 minutes before it happens again. Any idea what might be going on?
Confirmed same issue with an rx390 (Hawaii)
Edit, mine did it on 11.0 and 11.2 as well. But not on any 10 version or prior. It also seems to be a bit longer that 10-15 minutes between drops but they are sustained drops, not like a one off.
