Solar 7B needs ~9.0 GB but GTX 1660 Ti 6GB only has 6.0 GB. Try a smaller quantization or lighter model.
Operating mode
Interactive favors responsiveness, while light API and scale-out lean harder on serving readiness. The fit stays the same, but the recommendation lens changes.
Current mode
Balanced
Balanced for general local use. Keeps the ranking neutral across personal and serving workflows.

Usable VRAM is the main blocker for this model.
Not enough usable memory
The model needs 9.0 GB, but this setup only exposes 6.0 GB of usable VRAM.
Older PCIe generation
PCIe 3.0 is workable, but it compounds the penalty when you offload heavily or try to scale across multiple cards.
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 7B requires more memory than GTX 1660 Ti 6GB provides.
Solar 7B (7B parameters) requires approximately 9.0 GB of memory with Q4_K_M quantization.
The recommended quantization for Solar 7B is Q4_K_M, which balances quality and memory efficiency.
On GTX 1660 Ti 6GB, Solar 7B achieves approximately 11.1 tokens per second decode speed with a time-to-first-token of 17429ms using Q4_K_M quantization.
For coding workloads, Solar 7B on GTX 1660 Ti 6GB receives a F grade with 11.1 tok/s and 4K context.
On GTX 1660 Ti 6GB, Solar 7B can safely use up to 4K tokens of context. The model's official context limit is 8K, but available memory constrains the safe maximum.
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.
