Graphics Cards

[kankan1122]

Hi guys,

Before that I used RTX 2060 super and it worked fine with 8gb vram but after changing to RX 6600 XT, stable diffusion reported not enough vram of the graphics card. Is there any way to fix this?
Thank you everyone for reading.

I think you can try --medvram option, for other settings please check Stable Diffusion Optimization for more info.

I guess the reason why Stable Diffusion works on 8GB Nvidia card is because Stable Diffusion uses xformers library on Nvidia GPU, which lower the memory requirement. This library only support Nvidia GPU.

The following graph shows how xformers library would decrease the use of memory. Hope this helps.
