I all,

I have 2 windows 10 rigs, drivers 17.4.4 :

- H81 pro btc : 6*RX570
- MSI z97 gaming 5 : 6*RX470/480/570

Same problem with the two rigs : error system during the boot, windows try to repair but it fail

If i unplug the usb riser of one card, the rigs boot without any problem with 5 gpu.

Please anybody know what is the problem ?
