I switched from ethos to hive os and after that I have problem with one of my 6x rx 580 rig.
I have 4x Sapphire rx 580 and 2x XFX RX 580 Black Edition cards, Sapphires are fine and stable with about 32mh/s, but I cannot run the two XFX’s with normal, so about 30mh/s hashrate…
Sometimes when I boot it they are about 29mh/s and after couple of minutes they drop to about 18mh/s.
I’ve changed risers, switched them to other PCI-E’s, using modded bioses, tried modding bios with Polaris Bios Editor with the one click option (it finds Samsung and Hynix memory then, witch confuses me a little) and still the same. I also tried swtiching the bios switch, every time the same effect.
Of course I’ve tried diffrent settings for core and mem speeds, etc. My normal setup is 1100 core, 2100 mem, 850mV on Sapphire’s mem is set to 2200 an I have stable 32mh/s.
Please give me any hints, I’ve spent so much time on this case without any effects, I suspect it is something with bios or memory, but I really run out of ideas what to do…
