black screens after boot with GTX 560TI in El Cap

[bubbibub]

Hey guys,
i really need your help.
I installed 10.11.0 with unibeast. Boot only works with nv_disable=1, so no real graphics.
Injecting nvidia with multibeast (or just set "inject nvidia" in boot menu) does not work. Black screen when the loading bar is finished.
When I install the web-driver and multibeast and nvda_drv=1 it starts booting and then theres no connection to the Monitors anymore.
Same thing when I update to 10.11.1 first and use the newest nvidia driver.
There are two DVI ports with a Monitor on each.
I searched the forum but didnt find answers to similar problems.
Gigabyte Z97-HD3
Geforce GTX 560TI
16GB RAM
Sandisk 128GB SSD

Did you use the Webdrivers AND InjectNvidia=True? This should usually work...

 

[bubbibub]

Yes I did both. With injection and without. Neither does work.

Wich SMBios definition you're using? I had this issue using Mac Pro 6.1 but it works well with Mac Pro 3.1. We have different systems but same vga.

I am using MacPro 3,1 right now.
I tried IMac 14,2 , too. But also didn't work.

Did you try nvda_drv=1 ?

 

[bubbibub]

Yes, its somehow a bootflag as soon as I install Clover in that disk.
But it does not work.
Sometimes I do get a panic that says:

"Kernel Extension in backtrace:
com.nvidia.NVDAStartupWeb(10.0.7)
dependency: com.apple.iokit.IOPCIFamily(2.9)
"

same problem with gtx 560 ti -- black screen just when the logon screen should appear. My system works with yosemite chameleon though.

Try spoofing your device id to match GTX 560 (same GF114 chip): 0x120110DE, InjectNvidia=True
Maybe this works, I don't see any reason why it shouldn't work beside device id (my old 560 works fine).

Otherwise the Nvidia Web Drivers usually should do the trick...

Ok thanks, but how exactly do I spoof the device id? Thats new territory for me
