Im getting "duplicate job detected' message. anyone know what causes this? its on X16r nanopool
Unfortunately this is caused by the pool sending the miner the same job multiple times. Some pools have taken the short-cut of sending out the same job twice when they want to change difficulty.
That said, unless you're getting reject shares, it shouldn't affect mining and you can just ignore the messages.
Thanks. shares seem ok. just having trouble with a hynix rx580 on CNR now, hashrate showing 950h but pool side only 650h.
