Usable VRAM is the main blocker for this model.
Not enough usable memory
The model needs 75.5 GB, but this setup only exposes 16.0 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.

No, Solar Open 100B requires more memory than RTX A4000 16GB provides.
Solar Open 100B (100B parameters) requires approximately 75.5 GB of memory with Q4_K_M quantization.
The recommended quantization for Solar Open 100B is Q4_K_M, which balances quality and memory efficiency.
On RTX A4000 16GB, Solar Open 100B achieves approximately 2.0 tokens per second decode speed with a time-to-first-token of 96800ms using Q4_K_M quantization.
For coding workloads, Solar Open 100B on RTX A4000 16GB receives a F grade with 2.0 tok/s and 4K context.
On RTX A4000 16GB, Solar Open 100B can safely use up to 4K tokens of context. The model's official context limit is —, but available memory constrains the safe maximum.
