The RX 470 or 570 hashes between 900 and 1000 h/s.
You only need the right BIOS and the new amd driver.
Then set the rawintensity to 896, worksize 8, 2 threads (sgminer or gateless gate sharp).
My RX 470 hashes ~930 h/s XMR @1150/2050, 80W on the wall.
That´s it !
I cannot get SGMiner to start properly, I get the following error:
Error: clSetKernelArg of all params failed for cryptonight
Seems there is a
GitHub Issue open for this error as well.
I'm trying to mine Electroneum at the moment with a PowerColor Red Devil RX-580 Golden Sample, thought I'd give your settings a go, however, sgminer-gm starts up but wont mine (0 H/s) and I get the above error instead.
With claymore 10.2 I'm getting 798H/s with a single card, I'm hoping that is a respectable hash rate for this card.
