Render Bar Stops-Machine Restart -HELP-

[BLR]

Hello

Trying to get some help guys!
I have two different problems.

-While sending the Scene to Backburner the workstation reboot after several random frames.

-The other proble is that, Sometimes, Progress bar Stops. max Do not crash but the render bar stops at a certain samples and it no loger renders.

Any Idea or similar experience?

My System specs:
Windows 10
i9 Core
2x rtx 3090
64GB

Thanks in advance. Your help will be really appreciated.

good day.

What is Your PSU and what does reliability history say (type "view reliability history" into win search bar and see what errors does that give)?

I might be wrong, but crashing system and forcing reboot sounds to me like power issues. Not so long ago had the same one, where system started crashing and could not work in OctaneRender - switched PSU one, to new one, that I gad on hand and not a single problem (vs 13 crashes a day).

Thanks for your answer.

I will check what you say but the computer is new and the suply is a good one. I think it is more a question of gpu temperature but it is just an idea.

During render one of the gpus reach 80degrees. The second one just 50. I don’t know if this is the regular workflow.

80C is more than fine for GPU and hight temps could crash GPU, but not not entire system.

In my case PSU was also new, few months old and considered being one of the best in the market (AX1600i) however that does not mean good tech could not fail.

Thanks Glimpse. All I can see in the reliability is ¨SPDDUMP MFC Application Stop working¨

About the PSU Zalman ZM1200-ARX 1200W.

Thanks for your help man.

is this the exact critical error You see in the Reliability monitor? (at the crash time?)

some hints to read: https://answers.microsoft.com/en-us/win ... 36725ee1df

This might not be the exact issue, hence I'm asking what Your windows say. In my case, when I gad issues with PSU the reliability monitor (once I press on the message) said something like unexpected shutdown, computers was not turned off properly or so..

Ey.

Yes I get the same message. Windows closed improperly or something like that. The only other strange thing is what I Said before. All time the same. It is strange that sometimes the render progress bar freezes. Some times. Deleting some geometry fixed it. Really weird.

I am rendering heavy scenes and las time I had a problem like this in other machine I fixed is pumping up the vents and that’s what I was guessing temperature is the problem.

Thanks.
