Sapphire Pulse RX570 4GB - Black screen on Booting

My specs:
Intel Core i7 - 860
DFI Lanparty P55-T3eH9
Sapphire Pulse RX570 4GB
Gskill 8 GB DDR3
Connected to a TV via HDMI

I cannot get the system to boot either on High Sierra or Mojave. Things I have tried while booting
1. RadeonDeinit - True
2. Inject ATI - with and without
3. FakeID - 0x67DF1002
4. Framebuffer - Orinoco
5. Load Vbios - with and without (with Vbios I get a kernel panic)
6. SMbios - 11,1 and 13,1

I have Whatevergreen and lilu in EFI/clover/kext/others folder. When I boot from clover and verbose option selected, I get bunch of text and then suddenly the screen goes black. The same thing happens with Mojave and same clover options. Any help would be great.
