Is it possible to add more GPU Memory

[Ivanvaagenes]

Hi. Sorry for my terrible English.
I have a Gforce 4070 with 12Gb memory and it works ok with short videos.
Can I add a Dell H56H0 NVIDIA Tesla M10 32GB GDDR5 and use this with wan 2.2 and Comfyui?
If this is possible, will I have 44Gb memory for Comfyui to use?

mvh

Hey, amigo, nope, you cannot.

1. No VRAM stacking, no single memory pool possible.
2. The M10 lacks the modern CUDA features, FP16/BF16 support, and Tensor Cores required by modern video models like Wan 2.2. Your RTX 4070 is infinitely faster.

Try GGUF / quantized versions (Q4 or Q8) & run ComfyUI with the --lowvram startup argument.

Hay. Tanks for the answer :-)
