GTX970 and El capitan + clover

[akadyson]

Hey guys

Started to install OSX on my machine yesterday, everything is working except my GPU.

My specs are as follows:

I5 4670K
Gigabyte z87x-ud3h
8GB g.skill ripjaw 1600mhz
Asus strix gtx 970
installed on a 120GB crucial SSD.
OSX El Capitan 11.5 ( most recent version from appstore created the pen drive yesterday)
Mac pro 6,1 smbios like I always ran

After creating a working unibeast usb stick and went trough the installation without any issues, I ran multibeast with my previous known good working configuration so everything except the GPU is working.

After multibeast I ran the nvidia web drivers and they are installed, updated clover bootloader and added the nvda_drv=1 boot flag.

With this bootflag my screens ( 2* Dell ultrasharp u2515H 1440p one connected via HDMI and one connected trough DP 1.2) refuse to turn on, When remove the nvda_drv=1 and add nv_disabled=1 one of the screens pops on and I can work but without any acceleration and having artifacts.

Any tips or tricks that can help in this situation?

Great stuff thanks!

Will try another smbios as well since I read that 6,1 is generally only used with the x99 platform, will give the fix a go and else I will try another SMBIOS.
