Setup tutorial: Qwen 2.5 Coder 7B on RTX 4090
AI-generated, GPU-specific. Verified commands for your exact hardware.
Run Qwen 2.5 Coder 7B on an NVIDIA GeForce RTX 4090 with Grade S performance, using the Q8_0 quantization for ~123 tok/sec.
Prerequisites
Before starting, ensure you have at least 10GB of free disk space, a 64-bit version of Windows or Linux, the latest NVIDIA drivers (version 525.60 or later), and CUDA 11.8 or later installed.
Expected performance
With the Q8_0 quantization, expect ~123 tok/sec performance and 8.0GB VRAM usage. The remaining 16.0GB VRAM provides ample headroom for a large context window, enabling efficient handling of complex code tasks.

For optimal performance on the NVIDIA GeForce RTX 4090 with 24GB VRAM, set --n-gpu-layers to 40 to utilize the GPU efficiently. Enable flash attention (--flash-attn) to speed up inference and reduce memory usage. Given the 24GB VRAM, you can comfortably allocate 8.0GB for the model, leaving 16.0GB for context, which allows for a practical context window of up to 16,000 tokens.
Troubleshooting
Out of Memory (OOM) errors during inference
Reduce the number of GPU layers with --n-gpu-layers 30 or lower, and decrease the context length if necessary.
Slow inference speed
Ensure that flash attention is enabled with --flash-attn, and verify that your CUDA installation is up to date.
Model fails to load
Check the integrity of the downloaded model file and try re-downloading it using the 'ollama pull' command.
Alternative runtimes
Alternative runtimes include LM Studio and llama.cpp. LM Studio offers a more user-friendly interface and is suitable for those who prefer a GUI. llama.cpp is highly customizable and can be fine-tuned for specific use cases, but it requires more manual setup. For the NVIDIA GeForce RTX 4090, Ollama provides a balanced approach with easy installation and good performance out of the box.
