Let me know if there is any other info I should provide. Thanks

I have just tried Octane 4.01.1 RC2 and it is exactly the same. When I try to render the scene to PV Cinema 4D gets frozen for a second and it crashes without any errors. Or maybe there are some error C4D error logs but I don't know where to look for them.

Thanks

Here is the Cinema 4D log:

Nothing extreme or suspicious in the log. You may have problems with OS/driver/gpu.

Thank you.

* I tried clean driver install as suggested here viewtopic.php?f=86&t=70253 but it didn't help.
* So I tried to turn off one of the two cards in Octane settings and try to render the image - it worked with one card. But the other one failed.

Does it mean the other card has some malfunction?

Thanks

Does malfunctioned gpu work fine alone?

Does malfunctioned gpu work fine alone?

Nope, it is the one that crashes Octane renderer / Cinema 4D when Octane is activated.

So problem may be related with gpu. Pls try to lower gpu frequency.

Decreasing GPU frequency by 150 MHz helped. Thanks!!!

It's not a bug for Octane so as I expected.
