ASUS Crosshair V Formula Z 5 GPU Help

[wkholi]

Hello Guys

I have an ASUS Crosshair V Formula Z, I am trying to mine with it with 5 GPUs, I can not manage to have the 5 cards detected, I am not sure if it is a Driver or BIOS setting issue!

The board has PCIE2 but no GEN2

There is a  member who had the same problem a while ago and he opened a topic about it but the fix was not in the thread.

I have been in this for days and I want to know if it is possible or not.

Any suggestions would be appreciated.

Thanks in advance guys
