I was hoping that could be worked out. The FAQ says the whole S9 needs to be returned, but it doesn't make sense to do so (to me).

Running on the 2 boards, I'm getting 9.2GH

I'm jumping in with both feet. I have another S9 coming Dec 27-Jan2, Three L3+ this week, and I'm waiting on half the parts to build three ( 8 ) GTX 1070 rigs.

Thanks again for the advice.
