Was planning on getting three more, but alas I seem to have an issue with my 2080's card slots (seems I'm not the only one from this post) either.

It's only accessing slots A,C,F,H, and is sometimes showing cards duplicated or in the wrong slots too..

(Have done the obvious, new battery / factory reset)





If I put any four boards in A,C,F,H it works, but as you can see it thinks I have multiple copies of boards in some slots..

I suspect it's an addressing issue, so could be as simple as the board ribbon cables, but I'll investigate further and report back if I get anywhere.
