Setup tutorial: Gemma 3 1B on RTX 5070 Ti
AI-generated, GPU-specific. Verified commands for your exact hardware.
Run Gemma 3 1B on your NVIDIA GeForce RTX 5070 Ti with Q8_0 quantization for Grade S performance at ~637 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
You can expect to achieve ~637 tok/sec with 1.5GB VRAM in use, leaving 14.5GB of VRAM for context. This allows for a practical context window of up to 32768 tokens, maximizing the model's performance and capabilities.
1. Install runtimeOllama
pip install ollama
ollama config set runtime cuda2. 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 32 --flash-attn
ollama chat google_gemma-3-1b-it-Q8_04. Optimize for RTX 5070 Ti
For optimal performance on the NVIDIA GeForce RTX 5070 Ti with 16GB VRAM, use --n-gpu-layers 32 to offload layers to the GPU. Enable flash attention with --flash-attn to speed up inference. With 1.5GB VRAM usage, you have 14.5GB of VRAM left for a large context window, allowing for a practical context length of up to 32768 tokens.
Troubleshooting
Out of memory error during inference
Reduce --n-gpu-layers to 16 or 8 to lower VRAM usage.
Slow token generation
Ensure that flash attention is enabled with --flash-attn.
Model not loading
Check if the model file is corrupted or incomplete. Re-download the model using the provided command.
Alternative runtimes
Alternative runtimes like LM Studio, llama.cpp, and Jan can be used if you need more control over the inference process or specific features not available in Ollama. For example, LM Studio offers a graphical interface and advanced model customization options, while llama.cpp provides low-level control and optimization for specific hardware configurations.
