Greetings,
I am having trouble with one card in a rig with 6 cards. Two R9 280 and four Gigabyte GTX 1060 3GB Mini cards. Issue is with one of the 1060's. Just added these 1060's yesterday, brand new.
The three cards are mining fine with overclocks at around 19.5mh/s. The fourth card fails during mining. I have it at stock settings and it will mine at 17.5mh/s. After about 5 minutes, it will drop to 1.7mh/s. At this point the system will become unresponsive and MSI afterburner will freeze. If I wait, the card will eventually go back to 17.5mh/s and then again drop to 1.7mh/s
If I remove the problem card from the startup.bat, the rig is fine.
I have tried replacing the riser and cable, no difference.
Any suggestions? Is this card shot?

Problem card is #7
Underclocking -400/-500 didn't help either.
EDIT: Narrowed it down that the issue was happening with any card plugged into a certain PCIE slot on the motherboard. Moved the connections to not use that PCIE slot and everything seems to be working now. Using the ASRock H110 Pro BTC+ motherboard and the problem slot was the second one from the top labelled PCIE1.
