Is your card in that slot? Something not linking up like this is likely to be more of a hardware configuration issue.

I was aware of that one of the x8 slot was actually a x4 slot so I am
quite certain I have picked the right one.

It couldn't be as simple as since there is no disks connected to the
second channel so the 4 lanes for the second channel is not active?

I am aware of that and an upgrade to a 2x08 is on the todo list.
