The problem with Maxwell GTXs' GPGPU ability is likely driver related: See http://render.otoy.com/forum/viewtopic.php?f=9&t=42475&start=50 and https://www.redshift3d.com/forums/viewthread/3353/ .

Fixes graphical issues, but not opencl.
Still: Value 'sm_50' is not defined for option 'gpu-name'
GTX980 finds it's legs
Went from 29.9 fps (V-Sync locked?) to 48 in Valley.
Big jump.
Will run a Titan as well.
Anyone interested in power draw?
Hopeful I will figure out what the magic CUDA driver is for this card/OS.
May be yet to come.
openCl still MIA, going to guess Nvidia wrote it.....Apple is "checking it"...gotta keep that D700 sparkling.

Titan was around 1450 in osx, and 2250 in windows on extreme hd preset on 3,1.
CUDA works, only 64-bit, at least on gm107.
OpenCL needs a works, maybe patching their nvidia libs
Definitely interested in power draw... might it provide us with some clues as to if the future Maxwell-based Titans could be powered with 2x 6-pins and without needing a secondary power supply?
Titan in Yose
This is standard Titan, not Black
EDIT: Added R9 290X. Outside of myself and Netkas, no one else will have this running at PCIE 2.0, so expect slightly lower scores if DIY.

seems hdmi 2.0 with 4k@60hz is kind of broken on gtx9x0

phew, thanks for the heads-up! I wanted to buy a GTX 980 specifically because of the HDMI 2.0 port.
Given 4k@60Hz with HDMI 2.0 is claimed on Geforces website someones amiss!
Does anyone know if the display port(s) outputs 4k@60Hz correctly?
Whilst reading the spec on the gtx980, under OS Certifications I noticed
it lists FreeBSD x86. That seems to be partly used for OSX.
It's not said that the problem is related to the nVidia GTX9xx series. Some people in the posted thread are able to get 4K@60Hz with full Color-Bandwith.
So it might depend on the collaboration between used TV/Display and the graphics card. Looks like some "old" Samsung TVs are causing problems.
4K and Ultra-HD are very new features and so there are still a lot of problems. Most depending on the individual combination of out- and input-device. Even the new Mac Pro is very choosey in regard to the display – some work perfectly, others work with limitation, some completely reject to show a picture.
So in my opinion it's very difficult to get a working 4K setup, most devices have some problems with some others.
There are that many aspects which can cause the issue.
- graphics card
- graphics driver
- operating system
- cable
- TV/display firmware
- TV/display connectors
Could you please tell me how you managed that? Which Yosemite Version did you use and what version of the Web Driver? And which bootloader? Did you use any boot args?
I know, much questions, but i'd really appreciate it if you could answer them all
cheers
Ran my 2006 Mac Pro all day yesterday with my new GTX 970 with no issues. Purchased Logic X and installed it with no issues and new Yosemite drivers for my Apogee Ensemble it worked great.
Just don't zap your pram as it will change the card prefs away from a Web driver to default and then reboot is impossible. This happened and I had to remove the 970 and boot from the dongle with the original GT 7300.
Pretty cool beans!

^^^^^^ This is why I still keep my ancient GT120 card in my MacPro. Having a legacy Mac card makes this an easy thing to fix.
Hi,
This may be wishful thinking on my part, but will this work on a Harpertown 3,1 2008 Mac Pro? I'm currently running a GTX570 which runs one 4K monitor and another at 1600P but I'd like to run two UHD.
Thanks

OH, did you pick up the 970 from OEM or from MVD?
Thanks
