Saphirre HD7950 black screen

[TheVille]

HiYaa everyone!
I have a problem, my hackintosh works fine but only graphics is totally not working
My integrated Intel HD Graphics from my i3 works fine, but when i put in my HD7950 there's no way to get in OSX. Safemode, bootflags like aticonfig, graphicsenabler, pcirootuid and npci didn't have any effect.
The machine crashes on "gpu hardware vm is enabled", once it comes to this point i see a quick white flash and then back to the console where it does nothing anymore. Changing framebuffer personalities doesn't have any effect.
Monitor is connected through DVI, but i noticed when i connect through HDMI my monitor jumps to no input found like the GPU turned itself off at the point of GPU Hardware VM is Enabled.
IT doesn't matter if iGpu is enabled or not, and the bootloader is on a seperate EFI partition.

Machine specs:
- Gigabyte G1.Sniper B5(b85 chipset) rev 1.1
- Core i3-4150
- 8GB 1333mhz lowprofile DDR3 non-ECC RAM
- Sapphire HD7950 3GB
- Crucial MX100 512GB SSD
- Samsung 1080p monitor with HDMI,DVI and Displayport

I followed this guide and was able to get it working. Have to set GraphicsEnabler=No as well.

Since you have a iGPU, you should be able to set that as the primary graphics card in your Bios, which will get you into the desktop. From there the PCIe card should start working. Not totally sure, as I don't have integrated graphics.
