Setup tutorial: Gemma 3 1B on RTX 3080 Ti
AI-generated, GPU-specific. Verified commands for your exact hardware.
Run Gemma 3 1B on an NVIDIA GeForce RTX 3080 Ti with Q8_0 quantization for Grade S performance at ~477 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 525.60 or later) installed along with CUDA 11.8 or later.
Expected performance
With the recommended settings, you can expect Gemma 3 1B to run at approximately 477 tokens per second, using around 1.5GB of VRAM. Given the 12GB VRAM of the RTX 3080 Ti, you will have approximately 10.5GB of VRAM available for context, allowing for a practical context window of up to 32,768 tokens.
1. Install runtimeOllama

ollama install2. Download the model
Download the Q8_0 quantized version of Gemma 3 1B (1.0GB file) from Hugging Face.
ollama pull bartowski/google_gemma-3-1b-it-GGUF:google_gemma-3-1b-it-Q8_0.gguf3. Run it
ollama run google_gemma-3-1b-it-Q8_0 --n-gpu-layers 12 --flash-attn true --tensor-parallelism 14. Optimize for RTX 3080 Ti
For optimal performance on the NVIDIA GeForce RTX 3080 Ti with 12GB VRAM, set --n-gpu-layers to 12 to fully utilize the GPU memory. Enable --flash-attn for faster attention computations and set --tensor-parallelism to 1 to avoid unnecessary overhead. This configuration will allow you to achieve the best token generation speed while maintaining a large context window.
Troubleshooting
Out of memory error during inference
Reduce the number of layers offloaded to the GPU by decreasing the --n-gpu-layers parameter.
Slow token generation speed
Ensure that --flash-attn is enabled and try increasing the --tensor-parallelism parameter to 2 if your GPU supports it.
Model fails to load
Verify that the model file has been downloaded correctly and that the Ollama runtime is properly installed.
Alternative runtimes
Alternative runtimes like LM Studio, llama.cpp, and Jan can also be used to run Gemma 3 1B. LM Studio is a good choice for a more user-friendly interface, while llama.cpp offers more fine-grained control over optimizations. Jan is suitable for lightweight deployments. However, Ollama provides a balanced approach with ease of use and performance, making it the recommended choice for the NVIDIA GeForce RTX 3080 Ti.
