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
have you tried reseting the mothing to optimized settings and switching PCI riser card?
I tried all and still same problem
Are you trying to power three risers from a single PCI power cable? That often causes problems for me - try to stick with two riser per power cable and see if that helps.
Also, try using different PCIe X1 slots on the mobo, instead, just in case one of those is trouble. (But always include one card plugged into the PCIe x16 slot, connect to your monitor.)
Also, if using two PSUs (A and B) with a single motherboard powered by PSU A, make sure that a graphics card powered by PSU B also has the riser powered by PSU B. I find that powering the GPU and riser from different PSUs leads to instability.
2) all riser and gpu power are powered by same PSU. If riser is psu B, then gpu is also psu B
3) if I use ethos, can get 12 gtx 1070 working. But NVoC is only 4
