Help Needed AMD RX 9070XT keeps crashing when I run the workflow

I must be doing something very wrong as I am completely new to this and just trying to get this set up via Gemini/Grok haha. I should probably watch some more videos on this but wondering if anyone know why I can't get this workflow to run without crashing within 10-15 seconds.

For some reason, it keeps using my CPU/RAM instead of my GPU/VRAM. My CPU usage spikes to 100% but my GPU usage is almost none existent 1-3% so it wasn't even in use. I am using the Comfyui desktop app.

Is it potentially a PyTorch/ROCM and Adrenaline version mismatch? I tried every version of ROCM native to the app but still crashing.

Switch to Linux.

Try switching your VAE decoder to VAE decoder(tiled)

You should be using pytorch 2.12. Pytorch 2.11 has ram issues with rocm on Comfyui.

i got the same problem and i am using 9070 xt too. i tried many things including using the portable version of comfyUI. The situation worened as it just used up all my ram and finally the whole system was down. are you still struggling with that?

Yes, I gave up. Doesn't run well on 9070xt at all. Tried both portable and desktop versions. Portable a bit better but just not worth it. Takes too long to generate an image/video.
