ollama chat4. Optimize for RTX 3090 Ti
For optimal performance on the NVIDIA GeForce RTX 3090 Ti with 24GB VRAM, set --n-gpu-layers to 70 to utilize the GPU efficiently. Enable flash-attn for faster inference and consider using tensor parallelism if you need to scale further. With 9.0GB VRAM used by the model, you have 15.0GB of headroom for context, allowing for a large practical context window.
Troubleshooting
Out of memory errors during inference
Reduce --n-gpu-layers to 50 or lower and increase batch size to balance VRAM usage.
Slow inference speed
Ensure CUDA is properly installed and update NVIDIA drivers to the latest version. Enable flash-attn for faster performance.
Model fails to load
Verify the model file integrity and try re-downloading the model using the 'ollama pull' command.
Alternative runtimes
Alternative runtimes include LM Studio, llama.cpp, and Jan. LM Studio is ideal for a more user-friendly interface, while llama.cpp offers more control over quantization and optimization. Jan is suitable for distributed training and inference. For the NVIDIA GeForce RTX 3090 Ti, Ollama is recommended for its ease of use and performance.
