24 GB VRAM + 32 GB RAM · 960 GB/s memory bandwidth · Llama 4 Scout (109B-A17B) has 108.6B parameters (17B active per token).
Short answer
No. It doesn't fit in memory.
Needs ≈52 GB but only ≈47 GB of VRAM + system RAM is available after the OS and other apps.
Why it doesn’t fit
Even its smallest practical version (Q3_K_M) needs about 52 GB for the model, its context memory and the runtime. After Windows (≈4.5 GB), a browser with a few tabs (≈3.0 GB) and Open WebUI (≈1.0 GB), Desktop PC · Radeon RX 7900 XTX · 32 GB RAM has about 47 GB left, so it’s 5.9 GB short.
Ways to make it work
Close everything else
Not enough on its own: with every other app closed it’s still about 2.9 GB short.
