OTOY Forums

I just bought a GTX 750 Ti to use for Octane rendering. I have the latest driver installed. The Octane demo preferences setting shows a CUDA device
"GeForce GTX 75 Ti (compute model 5)"

But the log file says this:
################################################################################

CUDA device 0: Failed to find a CUDA binary matching compute model 5.0


I downloaded the 5.5 cuda dev kit and it wants to install an old driver (320) and claims it can't find any cuda devices.

I'm downloading the 6 beta cuda dev kit ( a 1 GB download) now to see what that thinks.

How can I get my setup to work? Has anybody done this?

I don't want to buy one of those ridiculous huge cards with a half kilowatt power draw, nor do I want to buy aging technology.

Thanks for any help,

Graham

Hi Graham,

The 750 is the first in the line of maxwell GPU cores with compute capability 5.0.
We have not done the work needed to make this generation function in octane yet. (Hopefully in the coming release candidates in the next few weeks we will be able to do this).

Thanks
Chris.

Thanks for the update. I will look out for it. FWIW, the 6.0 Beta Cuda dev kit didn't recognize my card either, and the latest nvidia driver mentioned support for 750 Ti in the release notes. Hopefully real developers have access to what they need to add support for it.

It looks like it will be a successful card. Fry's already has a couple of models, and it fills a niche with many users. Hopefully Octane isn't too slow on it. I know it is a few factors away from the best possible performance.

I'm in the same boat with the GeForce GTX 750 Ti
No GPUs at all I thought about going back to the 320 drivers but if they don't work then there is no much point.
I may have to go back to the GTX 680, as I did realize there would be such a huge problem with it working with Octane!

That's where Nvidias stupid naming Schemes lead to ... a 7xx series name, while actually having the newest Maxwell chip, that goes with the 8xx series. But intel does the same crap. 750ti's are nice cards though .... entry level performance, but very efficient and runs actual games as well at lower options.

Is Octane Render (demo or full version) now working with 750 Ti with Compute Model 5.0?

I tried this demo (2.06) on a Mac Pro with 750 Ti. Still giving the same error saying binary not found for CUDA 5.0

Am I doing something wrong?

No 2.14 demo until soon (this week - today or tomorrow).

hi, kibbycabbit. the current demo should work with 750TI gpus. Perhaps you need to install the latest CUDA drivers for Mac? Drivers are found at the nvidia website, http://www.nvidia.com/object/mac-driver-archive.html
