GA-Z270P-D3

Hi everyone

 I am building a rig using GIGABYTE GA-Z270P-D3  and  MSI duke GeForce GTX 1080ti.  Soon as I add the 6th GPU  my system won't boot I get an error  "reboot and select a proper device or insert in boot media in a selected boot device and press a key" and also cannot get to the bios with 6th GPU in place.  I have 6a bios the version that gigabyte is recommending for mining also I tried the last version F7 with no luck.  I tested the 6th GPU by removing the 5th and all worked fine so no hardware issues.  Any advice?  

Thank you,

Adam

You have to downgrade the BIOS to F6. After doing this all 6 cards will work , no more error Code12...
