I tried 0x19260002 on iMac 17,1 SMBIOS and not only did it not enable 1440P, it reintroduced the upper left corner graphics glitch.

After 169 pages, i finally decided not to wait for Pascal drivers and to buy a second Nvidia card (a GTX 960 in second hand, certified by Amazon.fr).

Hack working with:
- GTX 960 in first pcie of my Z170 pro : HDMI (1440p 60hz)
- GTX 1070 in second pcie, for windows only : DisplayPort (1440p 60hz)

Booting in HDMI in Windows (deactivate the GTX 960 in the control panel), select DisplayPort on your screen when you are in Windows to get your 1070 working.

Hack booting so with GTX 960. Installation with i7 6700k with HDMI: select iMac 17.1.
Install Nvidia drivers and booting back: black screen, so reboot without activating the drivers (spacebar when clover menu appears before booting in macOS).
Solution: install AGDPfix, and reboot your hack.

Booting perfectly in macOS 10.12.2 with GTX 960 and fully acceleration in 1440p :)
I am trying to do the same thing with a GTX 1080 & and a GTX 750 Ti, however because of the mobo and case I cannot place the 1080 in the second PCI slot, therefore I have 1080 in the first slot and 750 in the second.

With the 1080 removed & 750 still sitting in secondary slot, I've managed to install Sierra, make the Skylake work with no problem.

Afterwards, I've inserted the 1080 in the first slot and macOS sees the GPUs as two separate desktops, with the output coming from 1080 display as primary.

As a result, I've been looking for ways to power off the pci slot with the 1080 at boot by editing the ACPI, but with no success. How have you managed to solve this problem? Did you manage to disable that video output somehow?

* I've tried to set the Initial Display Output in bios but it doesn't make any difference for me.

just sold my 1070 after 4 months of waiting. No point waiting. At least I can unsubscribe from this thread now.
I also gave up. I'm buying a 770 4GB to supplement my 1060 and for compatibility with Linux open source drivers. Nvidia will never release the full firmware blobs for for Maxwell going forward. Sorry, there comes a point where you have to say "never."

Just wanted to add my name to the list of people giving up; I swapped my 1080 for a 980ti (made £100 in the trade at least) figuring that 6GB vs 8GB won't make all the difference in the world when considering that I'm gaming at 1080p, not 4k.

10.12.3 is now working perfectly and I can still run overwatch at max settings buttery smooth, so I shan't cry over my lost Pascal.

Yea, finally from buying the Evga GTX 980 Ti SuperClocked 6GB at first point before the pascal release.
I'm sick of waiting for the pascal support on Mac OS X :banghead:

So i have switched the GTX 980 Ti SC to my other desktop for my wacom cintiq..

And upgraded my X99 workstation to a Asus GTX Titan X 12GB and definitely works better
And is more powerful on video edits & 3D rendering, so for now a good improvement for the time.. :thumbup:
