I currently have the following setup:
Asrock H81 Pro BTC R2.0
6 x EVGA GTX 1060 3GB SC
2 x Corsair CX 750M
8 Gb RAM
Intel Celeron CPU\
Out of 6x GTX 1060 2x of the cards get this exact error
"Windows has stopped this device because it has reported problems. (Code 43)
At first should check BIOS settings. Flash last BIOS version, check PCI-e Gen option, 4G encoding option. There are much examples of resolving that issue
