Setup tutorial: Qwen 2.5 7B Instruct on RTX 3080
AI-generated, GPU-specific. Verified commands for your exact hardware.
Run Qwen 2.5 7B Instruct on an NVIDIA GeForce RTX 3080 with a Grade S performance, using the Q5_K_M quantization, achieving ~67 tok/sec.
Prerequisites
Before starting, ensure you have at least 15GB of free disk space, a 64-bit version of Windows or Linux, NVIDIA driver version 470.82.01 or later, and CUDA 11.4 or later installed.
Expected performance
With the Q5_K_M quantization, you can expect ~67 tok/sec and approximately 6.2GB of VRAM in use, leaving 3.8GB of VRAM for context. This allows for a practical context window of around 13,000 tokens, depending on the complexity of the input.

For optimal performance on the NVIDIA GeForce RTX 3080 with 10GB VRAM, use the --n-gpu-layers parameter to control the number of layers offloaded to the GPU. Setting --n-gpu-layers to 28 should maximize performance while keeping VRAM usage below 10GB. Additionally, enable flash attention (--flash-attn) to improve efficiency and reduce memory usage. With these settings, you can achieve ~67 tok/sec and maintain a practical context window within the available VRAM.
Troubleshooting
Out of memory error during inference
Reduce the --n-gpu-layers value to 20 or lower to decrease VRAM usage.
Slow token generation speed
Ensure that flash attention is enabled with the --flash-attn flag.
Model fails to load
Verify that the model file is correctly downloaded and not corrupted. Try re-downloading the model file.
Alternative runtimes
Alternative runtimes include LM Studio, llama.cpp, and Jan. LM Studio is suitable for users who prefer a graphical interface, while llama.cpp offers more fine-grained control over model parameters. Jan is a lightweight runtime ideal for quick prototyping. For the NVIDIA GeForce RTX 3080, Ollama provides a balanced approach with good performance and ease of use.
