Ok, I know that part of the problem may be that my PC is not the highes spec in the world and neither is my GPU, but I cant figure out what is oging wrong here.

I am on Windows 7 64 bit
Dual core AMD 2.4 Ghz
4 Gig RAM
nVidia GeForce 8800GTS (320GB) and definitely CUDA enabled
550 Watt PSU

I have tried the most recent beta and the octane8000.exe version.

I have also tried rolling back the drivers on the GPU and to CUDA 3.0

Now here is the deal:

1. Octane loads fine
2. Import of .obj and demo suite scenes are fine
3. As soon as I click on the mesh to begin rendering (even on the owest quality sub-sampling) it goes for about 5 seconds the freezes
4. If I load a scene where the model is not visible in the viewport there is no problem (I can see it rendeirng away the background)
5. As I zoom out, not long after the model become visible again...it freezes (again not just octane but the whole PC stops dead...no blue screen, just 100% inoperable including disk access stopping)

Any ideas please?

I will be upgrading my system in the near future (saving up the pennies), but I cant understand why all look well until rendering starts?

I had the same problem,

Try to underclocking your CG.

(even i you never OC your CG, some constructor sold them a little OC)

download Ntune:

For me it works fine with this tweak:

I decrease the core bus: 600Mhz -> 567Mhz
And the Memory bus: 1050Mhz -> 999Mhz

Thanks for this.

I have managed now to get the octane8000.exe working....but I had to SERIOUSLY U/C before it woulf work

About to try the beta now....
