Shutdowns When Using Denoiser (RTX?) Tweet

[ukirishan]

Has there been a solution found to the power consumption issue causing many systems to shutdown (Or laptops to disconnect from power supply and run in battery mode) when using AI denoiser and rendering to picture viewer in C4D Octane 4?

I'm still having this issue after months and no solution from Otoy yet.

Windows 10 Home
Intel Core i7 7700
32GB ram
2x Nvidea 1070

C4D 20.059
Octane 4.01.1
Nvidea 417.71

Rendering at 1920/720/ both cause crash

I also am wondering why there is no solution coming from Otoy. Apparently this issue is strijing many users, some even with very powerful PSU setups. Maybe some kind of software solution should be found for this.

At the moment it is looking like a hardware/driver issue isolated to a couple of devices, possibly caused by manufacturing error since it doesn't happen with all of them, but this is just speculation.

We have found that clock limiting these problematic devices using nvidia-smi helps. But this is NOT something we recommend users doing. We should wait for a solution from NVidia for this.

ok just a short update to this question. i've followed beppe's advice to check if something can be optimized about how much power the card gets inside my macpro. i've found a device sold by evga called "powerlink" which is supposed not only to ease power cable connections but also to balance the supplied electrical power from both cables. i was just curious if this would work with my 980ti inside the macpro 5,1 - and bought one. the result is that now this machine can render all denoised passes up to large sizes without issues. i am now in the process to upgrade my 2 other machines with this device to see if it does work in networked way as well. i will keep you updated!

thanks beppe for giving the tip to double check powering the card!

cheers

Hi Markus,
great!!!
Happy to hear that you have solved
Here is the link at EVGA PowerLink for other users:

How do you have connected it to Mac Pro?
Happy Mac GPU Rendering,
ciao Beppe

but also to balance the supplied electrical power from both cables.

if You have single rail PSU, You do not balance anything as those two cables come from the same contacts inside PSU, but on Multi-rail design that might help as each of those could come from different rails.

the important bit though is "Integrated solid state capacitors give you power filtering" - that would help for sure and that's why getting a bit better power supply with cleaner output is worth taking a look at.

how powerful PSU matters little..the importance here is how clean the power goes out. Getting higher efficiency PSU with better regulation is good idea to start with if You want to avoid stability issues.

I can confirm that a PC with 4xRTX2080ti with 1700W PSU crashes when using denoiser. Octane for 3ds max 2018.1.3. When denoiser is OFF all is cool and stable even at 80C GPU temp. When it is turned ON it crashes max after several frames rendered. If too many cards are aligned to denoiser - PC restarts right after denoiser kicks in. Support told me to get a second PSU (my case does allow it). So it seems to be not a single user issue. For the devs - try to rework denoiser in the way so it does not draw too much power from PSU. It really is annoying.

This was happening before with Denoiser in Version 4, never was able to fix it.
Bug Report: viewtopic.php?f=86&t=70436

Win 10 Pro
RAM 32GB
GTX 770 (Monitors/Not Rendering)
GTX 1070 (Rendering GPU)
Network Render ON or OFF
Cinema 4D R20.030
Octane 4.01.1-r2

When rendering to the Live Viewer with Denoise ON & Denoise on Completion ON, It will do the full render and at 100% will Hard Crash the computer.
When rendering to the Live Viewer with Denoise ON & Denoise on Completion OFF, It will do about 5% of the render & will Hard Crash the computer.
When rendering to Render Viewer with Use denoised beauty pass ON, It will do about 5% of the render & will Hard Crash the computer.

We have just done a completely clean install of Windows 10, Cinema 4D & Octane.
This issue is not the case on the (2) Mac Pro Cinema 4D/Octane machines we have.

That's right, he said it wasn't a plug-in issue...

Please export your scene as Orbx and post in standalone topic if you could. It's not directly related with plugin.

Ok guys. It has nothing to do with the power issues or insufficient power supply. As i was recommended by the support i ve got myself a second PSU. Right now ive got 2900 watts of power. for 4 rtx2080ti. And it still crashes. Even with 1 card assigned for denoiser. So guys if anybody faces the same issue - DO NOT buy additional ram (as i was recommended firstly) and DO NOT buy additional PSU. Those are not the cause of the issue. Not the frequencies, not the temperatures. I dunno what is the cause really.

p.s. It is also not the octane version that matters. Just tried 4.04 instead of 2018.1.3 - crashes in the same way.
