Blender keeps crashing

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.
