Issues with my miner

I cant boot more then one card at once, I have a BTC H110 Pro, and 1 card in slot 16x, but any more cards I plugin in will not work. I have tryed new risers, diffrent cards, and more RAM, but nothing fixes it.

I have also tryed creating a swap file. I have an error on start up “Invalid ROM Header”, but from what I can see, this is not related to my issue.

First at all check PCI-E speed for x16 slot: Gen2 - prefer

It is Gen2

4G decoding -enabled ?
