Strange - we have opposite problems! My lyra2v2 hash rate is spot on - on Zpool, the average over the course of the day is pretty damn close to what my rig sees. For my S7-LN, right at 20% of my hash rate is rolling over to the next pool on the list (and only 10% of that is recognized in the other pool, so I'm effectively losing 10% of my hash rate). This is without #xnsub - if I append it, my rate never goes about 800-900 Gh/s.
In looking at my hash rate graph against the pool's, and my dropouts line up fairly precisely with the pool's. How can that be expected behavior?
I have again started pointed a S7 at zpool. It is consistently reconnecting but, is not getting kicked off needing a hard-reset like it was before.
I do see the results of the disconnects (pool hashrate drops massively is one clue) and my miner hashrate resets then climbs back up.
So it seems as whatever garbage that was keeping the miner from reconnecting or getting hung waiting to reconnect... is no longer happening. My only issues now are the normal power issues associated with living out of the city in the country.
The lyra2 port seems to waver greatly on my hashrate it is seeing. Its very odd.... So sometimes I get a full reward (~25Mh) and sometimes a partial reward (~13Mh)... I am wondering if I force a diff that this will change my hashrate consistency.... telling me that the diff is going just a little too high for the speed of the coins its mining.
