This thread is continue from "The video card dose not responds." / viewtopic.php?f=45&t=68390

I try simple light scense, that only have environment light.
I meet following trouble,

How to fix this ?

CUDA error 715 on device 1: an illegal instruction was encountered
CUDA error 715 on device 2: an illegal instruction was encountered

My best guess is that one of your cards is faulty. Try turning various card off to see if you can identify which is causing the issue. And try without network rendering.

Thank you for your support.

I tested lot of pattern of GPU group.

I found following result.

Case of Most Stable.
Using one GPU on Host Computer, and must be set "Kernel->Parallele Sample 1 or 2 / Pass Tracing Kernel".
Network Rendering Node has no trouble, we can use all of Network Rendering Node.
I test each GPU(3 GPUs), this result is same, therefore this trouble is not on GPU, caused by Octane Inside.
Multi GPU on Rendering Node is no reretionship with this trouble.

Case of Unstable
1. "Kernel->Parallele Sample 4 and more"
2. Use 2 or 3 GPU onHost Computer

I found that this kind of trouble occur from Octane V3.07-08.
More younger version dose not neet this trouble.

You state above the problem occurs with Octane 3.07 and 3.08. However you also reported you are using the Octane 3.05.2
OctaneRender for Plugin version 3.05.2.88
So is the information you have provided accurate pls?

I try re-test with Octane 3.05.2, unforunary I remove old verions, and deleted this verion from your site.
Becuase, old time I meet this kind of problem, but not so offen than 3.07-08.
I can't say it is same, I'm sorry.

Additionaly, V3.07 is better than V3.08.
Case of trouble sense, in this case V3.07 can render 1 or more pictures, but V3.08 get touble after 5 min(I feel strange this, but always same).This case use 3 GPU in main PC and Parallel Sample as 8 to 16. if 1 GPU and Parallel sample as 1-2 has no touble.

Have you installed Octane Standalone via the EXE installer on your master and slave PC's as per http://poserphysics.blogspot.com/2016/03/before-you-submit-octane-support.html?

This is not related to the Poser plugin, and is an Octane or Nvidia issue. So can you pls report it to OTOY via the Support menu option above, or in the Octane Standalone release thread.

Thanks
