CUDA error: Launch failed in cuCtxSynchronize(), line 1372

Anyone have an idea as to why I am suddenly getting this error while trying to render a particle scene? I did notice the blender cache is pretty huge for the simple scene ~15GB. Is blender running out of RAM/VRAM or such? The system has 16GB of RAM and 6GB VRAM…


Hi there. By chance, did you ever resolve this? I’m having the same issue.

Pretty sure your GPU ran out of memory, did you try rendering with CPU?

Try using a both gpu and CPU compute. With this option set the tile size to around 32. I know it’s the total opposite of just gpu rendering but smaller tiles work better with the combined option. Also when I was having a similar issue I got a second gpu so that I could render on one while having the other dedicated to display so that my display didn’t take away from my render resources. Hope this is helpful.

I have the same error, same problem. Even with smaller tiles or cpu & gpu rendering. Only thing that works here is cpu rendering but hey, did I buy a NVIDIA or didn’t I?
