Problems of shares rejected nanominer 1.8.0 AMD RX580
Hi all, I have test the nanominner 1.8.0 and no work fine, I have many rejected shares, until the work of my miner down, in the versión 1.7.1 my minner work fine.
I have a minner with ubuntu 18.04, three AMD RX580 and one NVIDIA Geforce 1050ti, the GPU's AMD have a custom firmware the speed is at 30MH/s.
someone know what going on?
Thanks
