Hello AMT,
      As an update I have the following:

1.   Top card never turned on so its most likely dead.
2.   Second card hashes at a lower value. This is the card whose heat sink is a little off from one side.

      Should I go ahead and send back the top card and get a replacement? Its not doing anything sitting in the unit. Also do you have any steps on reseating the heat sink on the second card? Or should I just not touch it?

      Let me know,

Thanks in Advance!
