Hi, i've been mining with 2 r9 fury's for a while now. i got one from ebay used and it only gets 50% of the other two. how to troubleshoot this?

ETH: GPU0 13.875 Mh/s, GPU1 26.397 Mh/s, GPU2 26.743 Mh/s

not enough detail to tell about the first one but even both others are way under their max hashrate. If you are on Ubuntu 16.04 go with the ROCm Kernel for the drivers they got all the benefit of being designed especially for the fidji/vega(hawai as well) and blockchain computing. Even with the older crimsons you should be able to reach 31-32 mhs each in dual mode with claymore ( with 985 mhs/fury on decred) ( 1125,500 clocks, fans at 80-85%). Got hundred of them.... solid for mining but they tend to draw a lot of power so... going with the ROCm kernel would be ideal since they are the only drivers out there that can manage an undervolting...

I could push them a bit more but at these clockspeed I got no invalids, temps are good ( 54-60 ) and its as stable as stock clocks.
