I actually have two monitors connected to a video card, so I'll try to disable the GPU connected to the monitor and watch what happens

LightwaveGuru If I do not succeed to render the scene (with 3 cards), I send to you the scenes, so you can do a few tests

Thanks

ok. we will find the failure!

If used one by one all the GPUs work fine, but with all enabled Octane crashes, perhaps the problem is related to the PSU, that can have not enough power for all the GPUs, or it could have also a hardware problem.

You can enable the log file in the plugin options panel to see if there is any report about CUDA errors.

Problem is solved. I test the scene from slade with 4x titan x 12 gb vram (maxwell)

triangles = 20542317
GPU Used = 8372
GPU free = 1609

sys ram used 35,97 gb!

anybody remember if i say that 32 gb sys ram is not enough

hi slade,

put 32 gb sys ram more in your computer! the reason is not octane. the reason is this monster scene himself!

(check the testrender in your PM)
