Usable VRAM is the main blocker for this model.
Not enough usable memory
The model needs 70.2 GB, but this setup only exposes 24.0 GB of usable VRAM.
Add more VRAM headroom
The first useful upgrade is more dedicated VRAM so you can fit the model without shrinking context or dropping to a much lower quant.
