Oh yeah for compute it's a different story because you are earning money from those compute unitsbut for using apps like Cinema 4D with plug-ins like Turbulence FD they’re still a great card for the price right?
not good news, sorry to hear it. Did you upgrade the driver before you installed the Ti? Have you reseated the card?
drivers were updated, Cuda too. I keep swapping them out. Reboot and it works good for undetermined amount of time then just kind of flakes out. Cursor gets all slow and notch. Swapped out the 680 and I notice that does it too but takes longer. Something is up. Memory seems to be used up as artifacts start to appear on the screen, which is hard to believe on a 6GB card. Seems to flake out faster with a browser window open. No browser open and I can get some good work out of it. Baffling. Currently testing to see if the internal temperature has something to do with it....which seems to show some promise. will keep you posted.
Thanks for delving into the problem, good insight. Also, good that it’s a fixable bug and that you can instigate a temp fix with fan control. Have you got a flashed version of the Ti from MacVidCards or are you using a stock card without a boot screen?
I added a dedicated 8pin connection straight from the PSU and powering just one 6pin off the logic board...
I am using a PC EVGA card with their 2.0 cooler. It is not flashed. Boot screen is black, but have no trouble with that. SSD boots so fast you barely notice it is gone.
Also, how did you do this? I assume soldering onto the PSU was involved?
I've read about people running from a separate PSU or just from the internal PSU, but not from both as you appear to be doing.
Think that might not be the case if you run the Nvidia Web Drivers, which you need to do to run this card... But yes, as you said the difference is not as dramatic as you might think...^ I can answer that it will run at PCIe 1.0 speed, but really I don't think it's much of an issue at all, I've tested my 980Ti extensively in windows and it performs as it should.
(I power mine with an external PSU).

Updates to PCIE specification were to primarily address servers with a lot of network traffic that are using enterprise SSDs on the PCIE slots. For gaming it makes such a small difference.
And I assume it makes an equally small difference for graphics and 3d work too?
I did read a post somewhere on here about the 1.0 & 2.0 difference and how it was largely meaningless speedwise. I'll try and find it and post a link here.
I’m using the GTX 980 Ti (Gigabyte G1 Gaming) for about 3 weeks with my old Mac Pro 5.1 now, it replaced a R9 280X OC.
As the fans aren’t needed under 60 degrees they stand still most of the time while doing normal „office stuff“ or „simple photo retouching“ with Photoshop.
But to be honest I’m currently using this Mac + 980 Ti for gaming @ 4K with Windows 10 which is why I haven’t really tested working with my Adobe CC Apps or Capture One on OS X.
With OS X ( 10.10.3 + NVIDIA Web Drivers) both GTX 980 Ti and the old GT 120, which I use to get a bootscreen, are recognized and seem to be working fine.
On Windows 10 the drivers for the old GT 120 (listed as GT 9500) aren’t included within the new drivers for the 980 Ti which is why additional drivers are installed - the result is an „error 43“ and the GTX 980 Ti is disabled…
I’m still looking for a (software, drivers, Windows) solution but apart from this I’m quite happy with the performance of the 980 Ti on Windows 10 - the fps @ 4K with games like „Witcher 3“ are great.
While playing the GPU load is of course quite high, I only use the internal power of this old Mac.
In order not to destroy the Mac I’m not only using the standard 2 x 6-pin PCIe power cables of the system board but also 4 x SATA-Power.
Up to now this works fine.
I ran into that after first getting my 980Ti, figured that out the hard way... Also can't launch the Nvidia control panel unless you then disable the GT120...Don't allow Windows Update to ever install any Nvidia driver otherwise it enables the GT120 and disables the newer cards. If this happens:
-uninstall any Driver software
- delete both cards from device manager
-When it reboots the GT120 will be installed as a generic Windows card. Never allow Windows Update to install any video driver
- install the latest GeForce driver direct from Nvidia to enable the newer card
I just got a GTX 980 Ti and I have to say I am having some trouble. I installed it, boots off the web driver, but it is far from smooth. Mouse is jittery, floaty and sometimes like pushing mud. GPU programs like creative cloud eventually bog down. It's very hard to use in the yosemite interface. Put the GTX 680 back in and it's all normal.
Can't figure it out. 980 reports excellent render times in Blender and Cuda-z, but it doesn't seem to be working to it's full potential on the Mac UI. Thought it was maybe drivers, but then saw that others were using it just fine. It reports in system profiler as "nvidia graphic device" and in photoshop shows up as experimental nvidia...not sure what I should do. I would really like to use this card. Could it be it's not getting enough power?
