[ardian_ian]

Hi Guys..,

I have a problem with my octane.., When I try to combine my GTX 580 & 570 together to render e scene (no matter big or small) ,
after a few minutes..., my screen gone black... but the cpu seems still running normaly (the numpad light is on so the cpu not crash but only gpu matter),
I just wondering could someone tell me whats going on?

You should check if the cards have enough power and if they are not overheating while rendering.

Thanks Roeland
the power is ok, i'm using toughpower 1200watt, and the heat is around 78'C.., is it OK?

[roeland]

That sounds OK.

Does Octane run stable on only the GTX570 or the GTX580? Is your display connected to one of those two?

Are your graphics cards on their standard clock rates? If not, try if it runs more stable if you disable GPU overclocking.

It may also be a problem with driver settings. Try if doing a clean install of the NVIDIA driver solves the problem.

Yes they are fine when running alone (single GPU render)...., and yes one of them is connected to my display.
My GTX 580 is overclocked by factory, but the 570 is in standard clock and fan reference.
So which one should i do first..?
re-install the driver or doing other solution (hardware setup)?

[roeland]

First try running the 580 at the standard clock rate if possible. Is the display connected to the 580?

[roeland]

Yes, try and see if the screen still goes blank.
