nVidiaGTX 750 2GB (GV-N750OC-2GI) not recognised...

Hi,

I have a 2006 MacPro1,1 that's flashed to 2,1
Running 10.10.1 with nVidia Web drivers (343.02.01f01) and an old XFX GTX280.

As soon as I swap out the GTX280 for a GTX750, I get blank display after boot and ScreenSharing from my MBAir shows a virtualised display.

If I remove the SSD from the MacPro1,1 undo/revert to Apple's bootloader and install it into a 2008 MacPro 3,1 along with the GTX750 GPU, everything works fine...

Please see http://forum.netkas.org/index.php/topic,8583.0.html for all my attempts/efforts to get it working in the past.

Too bad I missed this one. I could have had a look with a DarwinDump from the broken and working systems so if you're still here/using it (willing to) then please let me know. You can e-mail me the dumps (see source code for e-mail address).

It need nvdia_drv=1 as nvram Boot args , because the 280 is supported by Apple Drivers. But kepler GTX 7xx Series need graphics divers from NVIDIA or it will Not Display , and we get a black screen
