Looking for NVIDIA CUDA-capable devices...
NVIDIA CUDA initialized successfully.
Checking CUDA GPU #1:
GPU device name is: GeForce GTX 670
GPU error at GeForce GTX 670 (0): Unknown error (999) in getDeviceMemory(.) [4]
Check failed - will not use the device

Looking for AMD OpenCL-capable devices...
OpenCL initialized successfully.
Checking OpenCL GPU #1:
GPU device name is: GeForce GTX 670
This device is not supported
Check failed - will not use the device

just got a 670, its working fine in ae and prem (cs5.5)
Neat video plug doesnt seem to like it.
any ideas?
will it work if I enable opengl rendering upon export? (read in another post)
i'd still like to see it in the neat vid prefs.

thanks!

This may be related to CUDA driver version. Which version do you run? You can check that in System Preferences.

Thank you,

Thank you. We will prepare a special test version for you and I will send you a link by e-mail (probably tomorrow). Hopefully this will fix it for that GPU and that version of CUDA.

So when I had the GTX 670 in I was actually running

CUDA Driver Version 5.0.36

I put my GTX 285 mac in order to do a render and during that time updated to

"" 5.0.37

Today I swapped for the 670 and the Neat vid plug sees it.

I think im getting about 2 frames more than I did with the 285

im guessing a combination of things are keeping the 670s potential back

maybe nvidia drivers and maybe pci express 2.0 in the mac pro?

either way i'll wait for a mac os or nvidia update though im not sure the 670 is worth the investment as of yet. Improved CAD, Blender, though not by much. maybe next year.

i'll keep it in for a while longer, if you would still like to send anything my way.

Thanks!

So the problem was indeed likely to be caused by the CUDA driver and a new driver somehow fixed it. Please keep watching it and if you ever get the same error again, please let us know.

Thank you,
