Hello Folks,

my Setup:
Windows 10
6-cores a 4.7
64 GB Ram
2x GTX 1080ti (11 GB)
Cinema 4d S22, Octane Version 20.1.4

I have a bigger scene which i optimized. All textures are 1024 or less. Only 2 are 2K.
I rendered like 160 frames and now it interruppts all the time. The first frame is fine with enough vram. (7.72used/1.256free/11)
Then the second one needs suddenly more vram (8.689used/511free/11) and longer Rendertime. It´s exactly the same geometry and framing. After a few frames I get the cuda 700 Error.
I tried following drivers 451.77, 451.77 and 452.06.

I rendered a few scenes from this scenario. It was a kind of heavier scene but after optimization anything ran fine.

Does anyone had this cuda error with the newest Version?
Any ideas?

Best regards,
Dan

i forgot...
i also changed the timeout in the TdrDelay and the TdrDdiDelay to 60 sec.

So with the time outit renders 60 frames.
It takes 2.30 minutes/frame
Then the frames takes longer up to 4 min and then it crashed again.

Also removed drivers with DDU and reinstalled latest driver 452.06
I´m give it another try just in the moment. This is the last thing i know to do.

tips i read in this Post:
viewtopic.php?f=86&t=70433

ok. This did not help either = (
Any ideas, experience anyone?

Hi,
please, export the scene in .orbx animated format, close c4d, and render the scene via Standalone, via menu Scripts/Batch rendering, to see if you have the same CUDA 700 error.
You can open the log in Standalone by going to menu Windows/Create Log window.

Looking forward for your feedback,
ciao Beppe

Hi Beppe,

at the moment i´ve problem to export the orbx-file.
It stucks after half of the 329 frames. It has to render from 2647 to 2975.
I will restart and try again later.

Exporting the Scene to orbx doesn´t work. It always interrupts in the middle...
I have a few Cache files and Alembics. I don´t know if this is the reason?
I am working on a scene with the same setup at the moment. I only use one of the two graphic-cards.
Out of nothing this Error appears.

CUDA error 700 on device 1: an illegal memory access was encountered
-> failed to download symbol(stats data)
device 1: path tracing kernel failed

I couls send you the project. But with Cachefiles it´s like 8Gb i think...

Sorry. forgot to mention... the error happens while watching on the Liveviewer.

I optimized the scene more. It still crashes, but i was able to export it to standalone.
Doesn´t take the Expresso-driven animations. Do i have to bake all Expresso-related Objects to export it to Standalone?
