Setup tutorial: LLaVA 1.6 7B on RTX 4090
AI-generated, GPU-specific. Verified commands for your exact hardware.
Run LLaVA 1.6 7B (Q8_0 quantization) on an NVIDIA GeForce RTX 4090 for Grade S performance at ~119 tok/sec. Requires 8.5GB VRAM.
Prerequisites
Before starting, ensure you have at least 10GB of free disk space, a compatible operating system (Windows or Linux), and the latest NVIDIA drivers (version 525.60.13 or later) with CUDA 11.8 installed.
Expected performance
With the recommended settings, you can expect the model to run at approximately 119 tokens per second, using around 8.5GB of VRAM. This leaves 15.5GB of VRAM for additional context, allowing for a practical context window of up to 4096 tokens given the remaining VRAM.
1. Install runtimeOllama
pip install ollama
ollama init2. Download the model
Download the Q8_0 quantized version of LLaVA 1.6 7B (7.7GB file) from Hugging Face.
ollama pull mys/ggml_llava-v1.6-mistral-7b3. Run it
ollama run mys/ggml_llava-v1.6-mistral-7b --n-gpu-layers 40 --flash-attn --tensor-parallelism 14. Optimize for RTX 4090
For optimal performance on the NVIDIA GeForce RTX 4090 with 24GB VRAM, set --n-gpu-layers to 40 to utilize most of the available VRAM. Enable --flash-attn for faster attention computations and set --tensor-parallelism to 1 to avoid unnecessary overhead. This configuration ensures that the model runs efficiently within the 24GB VRAM limit.
Troubleshooting
Out of memory error during inference
Reduce the number of --n-gpu-layers or increase the batch size to fit within the 24GB VRAM limit.
Slow inference speed
Ensure that --flash-attn is enabled and that the CUDA drivers are up to date. Also, check if the model is fully loaded into VRAM by reducing --n-gpu-layers if necessary.
Model fails to load
Verify that the model file was downloaded correctly and that there are no issues with the Ollama installation. Try reinstalling Ollama or pulling the model again.
Alternative runtimes
Alternative runtimes like LM Studio, llama.cpp, and Jan can be used for more advanced customization or different use cases. LM Studio is ideal for a graphical interface, llama.cpp offers more control over quantization, and Jan is suitable for lightweight deployments. However, Ollama provides a balanced approach with ease of use and good performance on the NVIDIA GeForce RTX 4090.
