Greetings!

I have some strange problem.

Did someone have this config :

3900 Intel
MSI GAMING Z170A PRO CARBON
HiperX 4gb
Adata su800 SSD
Gigabyte 570 4gb G1
Evga 1600w

I have rig twin of this which is work with 7 580 4gb aorus, but in this config with 570 it don`t want to boot with more than 4 cards.

I have tried all drivers - 17.2.2, Robin Hood, Official Blockchain , the last driver, but nothing is happened.

Did someone have more than 5 570 4gb Gigabyte G1 on rig? Its silly question, but I have to ask
