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. Reported 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 time - 15min after start
What an interesting issue, not too often you get these deterministic ones that can be repeated easily! I'm trying to think of something in the miner that would be triggered after 15 mins, but there is nothing that I can think of really. I don't think this has anything to do with clocks etc, this is something else. Do you have any power management features activated in Windows? Anything that happens after 15 mins? SRB could be better than us controlling things from within the miner.
