Holy crap guys...I made progress.  Thanks to the link provided by smoolae, I have 5 cards working.  Only 1 card has the yellow bang now!

Here's a copy/paste of the post from the other post:
https://bitcointalk.org/index.php?topic=2401059.new#new

make new key "HackFlags" as (DWORD 32) set value 0x600 as (Hex) in
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\PnP\Pci\
and reboot.

User q43a0ef061ej provided this information.  Maybe if I fiddle with things a bit more I can get all 6 cards working!?
