Is that happening at start or at end of frame render?
Do you use denoiser ? Denoiser needs full memory i.e. actual VRAM not virtual (system RAM).

Also try some other scenes, don't test just on one scene, to be sure it's the system or scene that makes you problems..

Thanks Lewis your help is very appreciated

It happen at the start of the rendering just after the network has finished sending the data to the renderfarm.
Yes i use denoiser i don't have choice because it is a long render time per-frames and 1200 frames. (archvis scene)

I will try other scene to test for sure.

That's strange now my 3 RTX2080 TI are rendering even i got the error messages!!!
But for me if the render is going fine for the week-end i will be happy...

After about 3 frames rendered my second gpu stopped rendering while the firs and the third are still rendering...

No overheat on the monitor... hummm??????

Same card configuration...

Can you pist your octane settings for GPU headroom and Out of Core ram settings.

Also does any other project give you same error or just this one?

Yes i also get this idea and raised the GPU headroom to 600 MB and let the Out of Core ram settings to 16 gig.

I am not sure why but now the beat goes on!
All GPU working fine!

Now rendering for all the week-end

Now very relaxed i can't wait tomorrow the 4th of May!

Good to hear.

Also as I suspected if GPU headroom increase helped then was mos certainly been Denoiser issue

Thank you so much Lewis!

Not everything run perfectly and i think the AfterBurner help because i did had many server reboot by itself due to unknown reason. I was thinking it can be gpu heat limit but with afterburner i was able to monitor the heat and the server was still crashing with gpu at normal temperatures so i have guess it can be the power consumptions on the main power supply.
I just lower the power of the gpu and set the fan speed from auto to a manual value and since no crash!

Hello,

for those who haven't seen it yet, you can find some exciting news on
