Is anyone else also having a really smaller hashrate in comparison with, for example, last week? I've been mining and for the last 48 hours my hashrate at the ethermine pool has been 140mh/s ?! The local miner is showing constantly 30.5mh/s on all 5 cards? Is there a global hashrate drop or is it just the pool?
For weeks, with the same 3 RX 570 GPUs, I used to have 1-4% (4% was in "bad times") stale share rate with ethermine, recently it was 5-15% with the same settings (core 1150Mhz and mem between 2060 to 2130Mhz), although I've a HTTP internet. The miner was submitting shares with a 5ms average ping.
The last two days, I start mining at anorak tech pool (
https://eth.anorak.tech/#/), not a single stale.
I briefly tried claymore 11.5, not any better.
Im testing with 9 rigs, in the pool Page i see 0 estales, but in Phoenix miner 1-4%
