Hi,

I'm running Ubuntu 16.04 with claymore 9.3 and amdgpu-pro drivers 17.10. There are six XFX RX480 8GB cards in the system with low power bios 29mh/s. Five out of six cards are mining fine but GPU0 is only doing 4mh/s.

GPU0 t=43C fan=56%, GPU1 t=60C fan=56%, GPU2 t=56C fan=56%, GPU3 t=57C fan=56%, GPU4 t=59C fan=56%, GPU5 t=54C fan=56%

I had the same setup running Windows previously and all cards were mining with ~29mh/s.

For some reason roc-smi cannot detect clocks on the problematic card:

I can also see amdgpdu powerplay and voltage errors in dmesg:
