Fingers crossed.
Thank you,

1-Are you with single gpu?
2-And working on different software(AE, Pshop, 3d software) while render is going?
3-What's your OS?
4-Have you tried to install different nvidia drivers?
5-Have you made any gpu stress test?

I'm asking to narrow down the possibilities if all gone fine on me. Because i've runned bepple scene several times without any problems. Also my Hardware is very stable and cannot see errors as some users.

Hi Aoktar,
1. Yes single gtx 780ti.
2. No.
3. Windows 7 64 bit.
4. Yes i tried but during instalation 309.08-desktop-win8-win7-winvista-64bit-international-whql.exe I have error "this graphics driver could not find compatible graphics hardware"
5. No. Is there a special software for this?
Thanks!

Hello Mono you didn't answear my question.

I discovered many people have issues with Ncidia drivers since W10. Those issues consider driver for display hardware.

Last night I've set a long render on my GPUs but without a display GPU. No failure.
I'd have to test it some more to make sure if this is the case.

I'm getting constant driver errors using Chrome for example.

I'm testing one method to fix this issue. I'll let you know if I succeed.

More to say - I don't get any errors in Octane log. Render just stops and that's it. I really belive it's a driver+W10 issue not related to Octane Render.

Try some recent drivers. I don't get any problems on this scene. Things are as i said that can be related out of Octane core. Also check gpu for high temperatures or defects.

If you could send us scenes where render problem occur, we can try to reproduce and eventually fix the issues. In the upcoming release there will be two fixes: One fixes a longstanding issue with the displacement intersection test which sometimes (i.e. once in millions) ends up in an infinite loop. The other issue was an infinite loop in the direct light tracing code. This one happened even rarer (i.e. once in billions of intersection tests).

So please, if you stumble over reproducible CUDA failures, then send either Ahmet or us a scene so we can investigate.

Update: Ahmet told me that you have trouble with Beeple's XANNN scene. I'm currently rendering it on my workstation with a Kepler, a Maxwell and a Pascal GPU and so far there have been no issues (I'm at frame ~40). Assuming that it stays like that, I think that your 780Ti is either overheating or defect or there is some other hardware issue.

Hi hellomono,
I can confirm what abstrax said, I have rendered more than 140 frames during night without any issue on my system with 2x780 + 970: It must to be said that the scene could be optimized, especially for objects with displacement, because now everything is movable
One question, have you ever installed the standalone at least one time?
During installation, it changes a registry in Windows that helps when working with displacement.

hmm so you guys are happy - i must say. me not.
Thanks for testing!
Bepeg4d - I must admit that after this problem i instaled standalone but the problem remain.

Thanks again guys,
Woytek

Hi hellomono,
we cannot be happy if you are not happy
What about internal heat in your machine?
Have you seen this post by rappet?

I think you are right about heating. I talked with IT guy and he promised me to do something with this.
I will let you know later how it will look.
Thanks again Guys!
