This is the error when I use Algorithm: Cryptonight V4 (R)

[2019-04-14 12:49:03] GPU0[BUS:1] result rejected for job[15] [low difficulty share]

I'm getting something similar with 1.8.3 and 18.6.1 drivers on a mixed RX 560 / 570 rig. Will be going back to 1.8.1 here shortly if the "low difficulty share" errors persist.


One other bug I noticed is that the min_rig_speed parameter seems to only be looking at one of the GPU's hashrate, rather the sum total.

Just clear the drivers with DDU from here and install 18.6.1
It must work. Also make sure you use normalv4 algo, because you can get 'low difficulty shares' if you use the wrong algorithm.

Also min_rig_speed checks the sum of all gpu threads, not 1 gpu.

edit:

tested for 27 minutes, works as expected. If it was looking at the hash of 1 gpu it would trigger a few times in these 27 minutes.
