GTX 950 Black Screen after boot

[Clu2t3r]

Hi everyone, 

several days ago i bought a new Gainward GTX 950. I already had OSX 10.11.6 running with a GT 650 so i thought changing the Card shouldn't be a big problem. Well i was wrong.

Every time I try to boot with nvda_drv=1 enabled all I end up, is a black screen and my monitor going into sleep.
I already searched the forum and tried several things, but every time I end up with the black screen.

I'm using an iMac 14,2 SMBIOS as it fits best to my CPU,
the web drivers are up to date (346.03.15f02) and i'm using HDMI,

when i try to boot with nvda_drv=1 enabled AND nv_disable=1/Inject Nvidia disabled i end up with a black screen,
i already tried to add the kext patch for iMac 15 Def's but it didn't help either,

but I still can't boot into OSX without nv_disable=1.

Any help?

I bought a EVGA GTX750 SC as folk in IRC said it would work OOB with my 3 displays

Regardless of what displays plugged in, nv_drv, etc it never worked with OS X- returned it.

Try to boot with nvda_drv=1 and GraphicsEnabler=No, its worked for me
