Setup tutorial: Gemma 3 4B on RTX 3060 12GB
AI-generated, GPU-specific. Verified commands for your exact hardware.
Run Gemma 3 4B on an NVIDIA GeForce RTX 3060 12GB with Ollama. Grade S performance, using Q8_0 quantization, achieving ~130 tok/sec.
Prerequisites
Before starting, ensure you have at least 10GB of free disk space, a 64-bit version of Windows or Linux, NVIDIA driver version 470.82 or later, and CUDA 11.2 or later installed.
Expected performance
With the recommended settings, you can expect ~130 tok/sec performance, using approximately 4.3GB of VRAM. This leaves 7.7GB of VRAM for context, allowing for a practical context window of up to 32768 tokens, which is the maximum supported by the model.
1. Install runtimeOllama
pip install ollama
ollama init2. Download the model
Download the Q8_0 quantized version of Gemma 3 4B (3.8GB file) from Hugging Face.
ollama pull bartowski/google_gemma-3-4b-it-GGUF:google_gemma-3-4b-it-Q8_0.gguf3. Run it
ollama run google_gemma-3-4b-it-Q8_0 --n-gpu-layers 12 --flash-attn --tensor-parallelism 14. Optimize for RTX 3060 12GB
For optimal performance on the NVIDIA GeForce RTX 3060 12GB, set --n-gpu-layers to 12 to utilize the full 12GB VRAM. Enable --flash-attn for faster attention computations and set --tensor-parallelism to 1 for single-GPU operation. This configuration will maximize the token generation speed while keeping VRAM usage efficient.
Troubleshooting
Out of memory error during inference
Reduce --n-gpu-layers to 8 or 10 to lower VRAM usage.
Slow token generation speed
Ensure --flash-attn is enabled and check that your CUDA installation is correct.
Model fails to load
Verify the integrity of the downloaded model file and try re-downloading it.
Alternative runtimes
Alternative runtimes include LM Studio and llama.cpp. LM Studio is suitable for a more graphical interface and easier model management, while llama.cpp offers more fine-grained control over optimizations and is ideal for advanced users. Jan is another option for those who prefer a web-based interface. However, Ollama provides a balanced approach with ease of use and good performance on the NVIDIA GeForce RTX 3060 12GB.
