[SOLVED] Nvidia GeForce GTX 1080/1070

Just finished talking to the Nvidia guys in their CES booth and they all seemed to be painfully aware for the demand for macOS Pascal drivers. They said driver development in general was a priority for them and that at this point the holdup was on Apple's end. They also said this was why they were pushing their streaming platforms so that they could operate in a more device agnostic environment.
 
Sorry @jebuschrast that made my lips into a sad smile. Typical sales rep ********.

Hah yeah. I saw that and thought 'only sales/marketing people would pivot a discussion about OS level drivers to their new shiny (just announced!!!) cloud platform'

Nvidia is guilty of some BS here; but it's important to note that they can't actually ship 100% functional drivers without Apple's help, and Apple has no motivation whatsoever to take on a QA burden for hardware they don't ship. And no, the existing web drivers are not 100% functional.
 
Yes seems like BS as the assumption was about gaming. Apple's sealed box strategy will pretty much remove the Mac from their ecosystem at some point (probably the point) but you still have to develop iOS software from somewhere. I still am confused of the idea if you follow removing creative pros and just about the majority of professional anybody from your ecosystem you leave basic consumer, I still can't see how that gets supported unless they have magic boxes in the future that support their internal dev effort. Or they open XCode.

Either was I don't see any chance on desktop enhancement nor drivers for PCIe display hardware, They haven't made any move in the last few OS revisions indicating they plan to enhance anything related. I'm shocked on how little real GPU enhancement they take advantage of in their apps. I was very excited when they spoke about OpenCL but they've dropped the ball on it. I assumed it was due to NVidia going strong with CUDA.

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 have a GTX 1080 and a GTX 960. My monitor is a 34" widescreen with:
  • 1 Display Port
  • 2 HDMI Ports (1 occupied by HTC Vive)
  • 2 Thunderbolt Ports
I was going to ditch my 1080, but is there a way I can use both cards without having to change the display port cable each time I boot into windows? Ideally I would use HDMI for OSX and then DisplayPort for Windows, but I don't think HDMI can do the 3440 x 1440 native resolution of my monitor.

Yea, just plug in the hdmi cable into the 960 and the DisplayPort into the 1080 and then plug both into the monitor. You will then just have to switch the signals using your monitor. Just make sure the 960 is in the first pci lane and that your bios boots first with the 960. Then in Windows simply disable the 960
 
I'm actually having to mess with this myself, except a 1080 and a 970 are the cards I'm using.
I left the first card (the 1080) in Slot 1 and put the 970 back in slot 2 so I could hackintosh again. DP to the 1080(So I would have it's HDMI available for my Vive) and HDMI to the 970. It seems to be working. (I have to manually switch input modes on the monitor, but that's just one button).

I did set the 970 to be the first boot option. Is there a reason I would need to "disable" the 970 in windows?
Since I bought the 1080 for my vive I was planning on seeing if I could use it as a "physx" card.
Or would that mess things up?
Just finishing my "rebuild" today so I'm not sure what pitfalls I may encounter with my current setup.

It's been a 2 day chore. And a forced "upgrade" to Sierra just to get my hack working. (long story)
Anyway. Any advice/warnings will be appreciated.

Gah. One simple driver and SO much could have been avoided. :)

The thing with using a maxwell card as a dedicated physx card is having phsyx being taken care of by the 1080 is usually more efficient anyways, since physx doesn't take much at all and the 1080 has newer technology and handles it better anyways. Plus you'd be using way more power, and using both graphics cards can cause more heat and noise. I have a 960 and 1080 in my build, and I actually don't have the 960 disabled for one reason alone, and that's because I have two 4K monitors and I keep one plugged into the 960 and one plugged into the 1080, and just switch the ports when I transition between OSs. I could have a more elegant way of doing this but it'd be too complicated with my setup.

Yes. I know what you mean. There are better ways of accomplishing the same thing, but I keep expecting the Pascal drivers to drop "any day now". Of course I have felt that way since June when I got my 1080.
Had been doing without my "hack" since then and just running windows 10, but some work issues forced me to find an
"at home" Mac solution and my backup iMac blew out it's graphics card.
So.
I'll keep this Frankenstiened power hungry mess for a while and hope I don't fry anything.

Yep.
Any day now.
