5 Things to Know About 64GB RAM for Stable Diffusion

32GB is enough for most Stable Diffusion users The bottleneck is usually the GPU, not system RAM. If your GPU has 8GB or more VRAM, system RAM barely matters.

64GB won’t make image generation faster Stable Diffusion runs mostly on VRAM. Extra system RAM doesn’t speed up generation.

64GB helps when training or fine-tuning large models For models like Llama 3 70B that don’t fit entirely in VRAM, more system RAM lets you hold more in memory instead of swapping to disk.

Your GPU is the real choke point for diffusion models More RAM just sits unused. Save the money for a better GPU or more VRAM.

Future you wants a better GPU, not more RAM A 4090 will improve your workflow far more than an extra DIMM.
