I just upgraded to High Sierra and this method does not work anymore.Hi, I want share my experience with this card. In 10.12.2, no need to change there kexts.
Just put FB= Radeon, and Fake ID 0x67B01002, just like in El Capitan.
My system fully working with those methods. My LuxMark shows 16000 and full 1050MHZ which is not working with your methods in 10.12.1
I know it was pain to find out the right edit in kexts. But no need to edit in 10.12.2
I hope this helped others.
If you do this, it will result in a black screen. Putting the HDMI cable back to the IGP HDMI output brings the screen back.
