Setup tutorial: Qwen 2.5 7B Instruct on RTX 3080 Ti
AI-generated, GPU-specific. Verified commands for your exact hardware.
Run Qwen 2.5 7B Instruct on an NVIDIA GeForce RTX 3080 Ti with Grade S performance, using the Q5_K_M quantization for ~80 tok/sec.
Prerequisites
Before starting, ensure you have at least 10GB of free disk space, a 64-bit version of Windows or Linux, and the latest NVIDIA drivers (version 512.15 or later) installed. Additionally, you need to have CUDA 11.4 or later installed.
Expected performance
With the Q5_K_M quantization, you can expect ~80 tok/sec performance with 6.2GB VRAM in use, leaving approximately 5.8GB of VRAM for context. This allows for a practical context window of around 8192 tokens, which is suitable for most tasks.

For optimal performance on the NVIDIA GeForce RTX 3080 Ti with 12GB VRAM, use the --n-gpu-layers parameter to offload layers to the GPU. Set --n-gpu-layers to 32 to balance between speed and memory usage. Enable flash attention with --flash-attn to improve efficiency. Given the 12GB VRAM, you can achieve a practical context window of around 8192 tokens while maintaining ~80 tok/sec.
Troubleshooting
Out of memory errors during inference.
Reduce the --n-gpu-layers value to 24 or lower to decrease VRAM usage.
Slow token generation speed.
Ensure that flash attention is enabled with --flash-attn and that the CUDA toolkit is up to date.
Inference crashes or hangs.
Check for any background processes consuming GPU resources and close them. Ensure your NVIDIA drivers are up to date.
Alternative runtimes
Alternative runtimes like LM Studio, llama.cpp, and Jan can be used for more advanced configurations or specific use cases. LM Studio offers a graphical interface and is ideal for users who prefer a visual setup. llama.cpp provides more fine-grained control over model parameters and is suitable for advanced users. Jan is lightweight and efficient, making it a good choice for resource-constrained environments. However, Ollama is recommended for its ease of use and robust performance on the NVIDIA GeForce RTX 3080 Ti.
