Thanks, but I have the presence shorts and the riser works with other cards as configured.

So this R9 280x works and hashes fine plugged directly into the x16 slot, but isn't detected when plugged into a 1x-16x riser which works with all my other cards, including other R9 280x's.

It seems like this R9 280x may be faulty in a way that disrupts the information flowing from 16x-1x, which doesn't occur when plugged directly to 16x.

Has anyone else run into this?
