Hi, I am using Asus b250 mining expert with Zotac 1070z.   I had installed v0019-1.3 version.   I managed to bring 4 gpu to mine. If I plug in 5th, i will get error "unable to get temperature internal error 15" and the particular GPU is down and the rest of 4 are working. I did changed 5 gpu to another 5 set of gpu and still got same problem.

I had plus the monitor to PCIe 16x gpu and enable the CSM setting. 

 If I install more than 5 gpu, can't enter to OS.  Black screen after boots.   Please help
