Azus Z270-A with 7 GTX1060 not working - crashes-HELP!

[swellcoins]

Hello,
I am just starting with my first rig:

Asus Prime Z270-A Motherboard
Asus Geforce (Strix) GTX1060 6GB x 7
Windows Pro 10 (64)

I started with only one GPU and then added the other GPUs one by one. I went up to the sixth one with no problems, all recognized by Windows and mining with Claymores miner. When I try to add the 7th GPU Windows crashes (blue screen) everytime after I login to Windows.

What seems to be the problem? I have the latest driver from Nvidia and the latest bios for the Z270. I also changed the risers and cables.

Any input is welcome!

1. Update Bioi 0906
2. Enable 4G decoding
If still not work, you would to reinstall Windows in UEFI mode. It will work.
