Hashrate is very unstable, going up and down from 15 to 29 MH/s.
Applied default patch using Polaris 1.6.7, no overclock.
When I replace Sapphire with any other brand I have - problem disappears and hashrate is stable at ~29MH/s.
So I assume the problem is with the card brand itself (as I have two of those and they behave identically).
