Blender keeps crashing

[GhostPrime (Phil)]

Im having an issue with Blender 2.91 Crashing after the second frame of an animation, sometimes it goes a couple more frames, but its not common. I have tried two different scenes and I get the same issue. Blender will close without generating an error report log file.

My PC Specs are:

CPU-3950x
RAM 3600 CL16 32GB
Mobo ROG Strix x570
GPU: Nvidia 3090 FE Running the latest drivers.

The scene will render using jus the CPU, but not Just the GPU, or both the CPU and GPU. The GPU RAM in the scene uses 19GB MAX (Of 24GB)

Any advice would be helpful! Thank you!

If you are able to reproduce the crash, then maybe you can get the developer team to look at it. The developer team would have to recreate the same crash on their own system. Otherwise nothing will get fixed.

I am able to reproduce the crash, as it happens everytime. What I’m unsure of is if it has something to do with my GPU, or drivers? Or scene?

The models im using are older models of mine and were created in Blender 2.80, so maybe that has something to do with it as well?

I’m at a loss

The same happens to me. Can’t use CPU and GPU combined when doing a render. It ALWAYS crashes. CPU by itself no problem. I have two 1050ti
Blender 2.91.2

I just can NOT get out of 2.79.7 …lol
I am cursed

Hi Phil,

There’s some potential solutions discussed here:

CPU+GPU rendering issues with RTX-3090 and AMD 3970X

This does seem related to the tile size. The crash happens with 32x32 tiles. I ran several more tests with varying tile sizes, and was able to render without crashes using CPU+GPU, although there is no measurable increase in render speed using larger tiles over solo-3090 GPU renders: GPU only, 32 x 32 tiles: 24 seconds GPU+CPU, 64 x 64 tiles: 23 seconds GPU+CPU, 256 x 256 tiles: 1 minute 11 seconds GPU+CPU, 32 x 32 tiles: instant power-off crash during initial tile renders I’ll try 16x16 n…

How beefy is your power supply? This could cause random failures.

Mike, you may want to monitor GPU usage to see if your running out of video ram. On Windows use the Task Manager and check the GPU tab.

My PSU is a 1000W so I dont think thats the issue. Im runnig a RTX 3090 and the scene isnt too big.

Do you have “Persistent Images” enabled in rendering->performance settings? If yes, try disabling it, I had some problems with that, it seemed that Blender was unable to handle larger images in VRAM when rendering animation and that caused crashes. I thought this was fixed at some point but not sure which Blender version it was.
Might check that later on my computer, maybe the bug is just back again?
