NVIDIA Releases Alternate Graphics Drivers for 10.10.0 (343.01.01) with 'Maxwell' GeForce GTX 970 an

[itimjim]

I too am looking to get my GTX 970 setup. Has anyone had any luck getting this working reliably? I'm on a 10.10.1 install.

On further investigation with my issues of getting the damned thing to display any form of 4k I've nailed this down to one of two things.

1) This is a driver issue. I've installed Windows 10 Preview onto an alternate SSD, installed the latest Nvidia drivers from the website and boom, 3860x2160/60p 4:4:4...perfect. So there's nothing wrong with the card, cables or recipient TV (Samsung UE40HU6900).

2) This is a legacy install problem. This isn't a clean install. In fact, it goes as far back as Snow Leopard, with various reconfigurations of kexts etc. So it might be worth doing a fresh install just incase there's something lurking in the background. So I will probably erase that Win10 install and put a fresh Yosemite on that to test.

Everything else works perfect, apart from CUDA moaning about needing an update. Keep you posted.

I just did the jump from an AMD 6870 to the gigabyte GTX 970 (OC Windforce). The installation went mostly without a hitch. My steps:

- nv_disable=1 in my clover config.plist (computer SMBIOS was set to Mac Pro 3.1, using AMD 6870, internal intel graphics disabled in bios)
- Turned off the computer
- Replaced 6870 with the GTX 970, plugging the monitor to the GTX (DVI port)
- Rebooted, installed latest nvidia web drivers (343.01.02f01), activated web driver (rebooted once again with nv_disable=1 to make sure)
- Remove nv_disable=1, add nvda_drv=1 and kext-dev-mode=1 in config.plist, reboot.
- Everything seemed OK at boot (card recognized, full resolution, etc.) but I had a lot of graphic related software crashes (preview, finder etc.). Activating injection for nvidia seemed to solve it but made the card name wrong in about my mac. Ultimately I changed the SMBIOS to imac 13.2 and these issues seem to be gone. I'm not actually fully sure if this is what solved it.

Does anyone has proved solutions/analysis of this problem in preview and other software ?

... BUT... Some benches I ran actually show very bad performance, such as cinebench: 58 (while I was getting 67 with the old AMD!). For unigine see he attached image... I don't know if it's any good. As for mac games it also looks alright but no fantastic progress. Any other feedback on performance ?

Last, I've tested one DVI (works), one DP (works), and HDMI doesn't.

I just setup my gtx 970 no issues. Booted with nv_disable=1 with the 970 installed, installed the web drivers, reboot without any flags, enable the nvidia driver, reboot again and its working flawlessly.

Which port and at what resolution?

 

[BThresher]

One of the DVI ports, 1920x1080. I will test HDMI soon.

I've had DVI dual link running at 2560x1440 at the same time as running HDMI at 1080p into the 4K TV.

If I can't get the 4K into HDMI resolved I'm going to have to run with a Windows build. I've just been a little bit sick in my mouth

Sorry, it looked like you guys were dealing with it just working at all. I probably didn't read far enough so your on a different issue.

 

[Pieroman69]

The card is recognized (Gigabyte GTX 970, latest driver)... but I'm getting a lot of graphics related crashes (preview, games crash a t launch). Any suggestion ?

Can you open up the console application and see what error's it is throwing?

 

[Pieroman69]

So the errors I was talking right above are actually all linked to these Channel exception! Exception type = 0xd Graphics Engine Error (GR Exception Error) errors. When googling them it seems that these happened for some nvidia cards, even on real macs, but I can't find some solid workaround. Any idea for the 970 ?
