I have been hammering away at solving this and I can't fix it.
Running the latest stable build, As soon as I enable path tracing Octane will start pushing my GFX cards and kill the system. Screens go black and the fans go into overdrive.
This happens in 2023 or r26.

Every other render engine (Arnold and Redshift) works fine. It's just octane

Last log file attached.

System:
Threadripper 3070

Hi,
please perform a clean installation of 516.94 Nvidia Studio driver:
https://www.nvidia.com/download/driverR ... 969/en-us/

To perform a clean installation, please follow these steps:


Then please, after reboot, download and run OctaneBench 2020.1, and share a complete screenshot of the result, thanks:

I installed the suggested driver, rebooted and ran Octanebench. I get the same result. As soon as Octanebench reaches the path-tracing section the machine crashes.

A crash often relates to a hardware failure. It would be suggested to look at hardware level (motherboard & PSU connections, properly powered components, etc).

I would agree, it as I stated octane is the only rendering engine that is causing this. I have tried it with Arnold as well as Redshift and Cycles and none of them have this issue. I can even push large scenes through Clarisse and I have no problems.

If also OctaneBench is crashing, the system seems not quite stable to me

Ok, please try to go to Nvidia Control panel, menu Help, and enable the Debug mode, to work with GPUs at default clock, and run again OctaneBench:

Octane is a GPU renderer, among all the ones you've mentioned, only RS is one (natively and originally). Unless you are on Clarisse Angie which is not yet a stable hybrid renderer, or Cycles GPU/forked GPU version.

If Octane is causing the crash, it would usually imply that it is triggering an issue that the others don't.

Further troubleshooting is definitely required. Do keep us updated.

I have checked every component and reseated all cables. I have also unplugged one of my graphics cards to remove power draw on the system, but the issue persists. I have also tried using the Octane version of Blender and it works without crashing. C4d and Octanebench still crash.

Which PSU?
What does the the crash log says? If anyone has been able to have a look, as I can't open it.
