Shutdowns When Using Denoiser (RTX?)

[SSmolak]

Can you try that with only two cards enabled ?

I guess I'm going to have to try that now going forward. Disable denoising on one card at a time and testing.

UPDATE:

Turned off denoising on the 1080ti and that 'seems' to have worked for the last 2 days now. I've had a render going for 13 hours straight now with all four cards at 100% whilst working in after effects and working on other projects in c4d - stable.

So PSU was not the issue.

Great, happy for you!
What about GTX 1080ti?
Does it have a monitor connected?
Is it in a slower PCI bus?

Hey. Is there any updates on this?
Same issue here. No matter how complex the scene is, PC just keeps shutting down using denoiser. I changed PSU several times but the issue is still here. The only thing i noticed, that denoiser works fine on resolutions lower than 1k (950x534 in my case).

PC is 2 month old

CPU: Threadripper 3970X
RAM: 128gb DDR4 3000mhz
GPU: 2 x rtx3090

Mobo: Trx 40 Designare
Cooling: EK

Drivers:
Nvidia - 472.84
C4d: R25.010
Octane: 2021.1 RC2

Same Problem here, my specs are:

CPU: Threadripper 3970X
RAM: 128gb DDR4 3200mhz
GPU: 2 x rtx3090
PSU: Be Quiet Dark Power Pro 12 1500w
Mobo: MSI TRX40 PRO WIFI

Tomorrow I'll try to connect the second 3090 to an external PSU 750W and retry.
I'll let you know

UPDATE:

I found that my PSU has an "overclocking" mode by applying a jumper which allows for much more stable 12v lines. This way I'm at 2740 calculated frames and it's still going. It used to crash at around 250 frames.
So I think it is a stability problem of the 12v lines more than the actual power of the PSU.

I had this problem before with my 980Ti and 1060. After 13 frames my pc crashed while rendering via the Picture Viewer.
The otoy support told me to do a fresh install of a stable nvidia studio driver.
This fixed my crashes
