For each of the voltages that a card might support, make sure that the

Browse Source 
socket also supports the voltage.  Some XV cards have appeared on the
scene (or cards that report they support XV), and in older machines
that have sockets that do not support XV, we were bogusly trying to
power them at XV rather than at 3.3V.  Now, power up the card at the
lowest voltage supported by both the card and the socket.
