Hello! I have an issue with unstable (floating) hashrate on DaggerHashimoto algo. In my PC with GTX 1070 Excavator shows iron stable 30 MH/s, it never changes. But on my rig with 6x GTX 1070 Ti hashrate fluctuates between ~150 MH/s and 180 MH/s, and it can hash on 150 for quite a long time (hours) before it goes up to 180, holds it there a bit, and then hashrate goes down again. Is there a way to make it more stable?
Unfortunately no. There are two things that need to be taken into consideration here. First, when mining daggerhashimoto occasionally new DAG has to be built, when that happens the hashrate will decrease for a bit since the miner isn't really mining at that exact moment. The second thing is the precision of the reported speed. You should call worker.reset 10 seconds after worker.add to get more accurate results (worker.reset purpose is to reset time interval measurement and achieve more accurate speeds). Also keep in mind that slight speed variation is completely normal, even expected. If you check the average pool speed over couple of hours, there shouldn't be any noticeable/big floating.
