Hy,

I´m Having some troubles With my GPU Cards..


I Have One GTX 580 and GTX 590

And Both work together fine with some projects

But There are some projects that it don´t happens...

Octane Open with this message on gpu bars 3 GPU (1x Failed).

Why this is happening with only few projects?

No idea. :)
Do you notice anything in common between with these projects?
Are they big files taking up a lot of vram or...have many textures or...
If you disable one of your cards completely will the scene load and run OK?
If you swap which is active will it still load?

My scene works, only one gpu begins to fail but the other two gpu keep working fine.

But i've found if I have autocad opened and open octane with large scenes my gpu will fail.

everytime i shut down autocad, gpu in octane will Never crash.

Is this a bug of octane or is this problem of my cpu?

It's possible that autocad uses some vram on one of the GPUs, causing Octane to run out of memory on that GPU.

One of your NF110 chips of the 590 is used for primary display and the 3D appllications. When the 1.5 gigs are filled Octane will fail but still tries to work with the other two chips but this will usually lead in a crash sooner or later...
