XFX RX580 - BLACK SCREEN

[andyzzsyk]

Hi all! Recently I have installed my first Hackintosh with the following hardware, I follow the guidebook and that can make me use it successfully.

Intel i5 6500
Asus h110m-a
Samsung 8gc 2133 x2

But when I change my display card from intel to xfx 580 8gb OC black edition, I cannot even load into the login page, I will get the black screen and the computer will keep reboot.

I have installed whatevergreen 1.3.3, that nothing happens.
I have installed whatevergreen 1.3.6, which even will make the computer can not load into the login page with an Intel display card. That makes me need to reinstall the Hackintosh.

The xfx card does not have any problem when I am using in window os.

What is the problem that makes me can not use the xfx card, I have seen this card show in the buyer guide, please help me, thanks all.

HI @donw35, I have typed
sudo nvram boot-args="-v agdpmod=pikera"
into command box, but it still cannot work with display card, it can only work in CPU display card.
P.S. I am now using whatever green 1.3.6
