Phoenix doesn't detect with GTX660

[Mr_P]

Thats because the graphics card is not a Mac graphics card with EFI firmware - therefore system profiler does not read it properly and causes issues reading other PCIe cards.

If you use a PC graphics card - you cannot use some other PCIe cards

Solution: use a Mac Graphics card
or
a PC Graphics card properly flashed with EFI firmware (at your own risk…)

If you turn little switch on the ATI I will get same problem, ATI 7950/7970/8970 have BIOS/EFI firmware.
