Every time
strictly after 15min uptime current hashrate becomes too high on all or almost all gpus (the can be different on other rig start). Avg begin to drop. Reportet pool hashrate aim to avg. I've tried to reduce intensity to 3+2, L3+2, reduce overclock to extremely low - 1100/1850 on baffins and 1180/1950 on lexa but problem occures again at same uptime 15min.
