AI-generated, GPU-specific. Verified commands for your exact hardware.

TL;DR

The Llama 3.2 3B Instruct model runs at Grade S on an NVIDIA GeForce RTX 3070 Ti with Q8_0 quantization, achieving ~106 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 525.60.11 or later) with CUDA 11.7 installed.

Expected performance

With the Q8_0 quantization, you can expect the model to run at ~106 tok/sec, using approximately 3.7GB of VRAM. This leaves 4.3GB of VRAM for context, enabling a practical context window of around 100,000 tokens.

1. Install runtimeOllama

curl -L https://ollama.com/install.sh | bash
ollama install

2. Download the model

Download the Q8_0 quantized model (3.2GB file) from Hugging Face.

3. Run it

ollama run Llama-3.2-3B-Instruct-Q8_0 --n-gpu-layers 32 --flash-attn
ollama chat Llama-3.2-3B-Instruct-Q8_0

4. Optimize for RTX 3070 Ti

For optimal performance on the NVIDIA GeForce RTX 3070 Ti with 8GB VRAM, set --n-gpu-layers to 32 to utilize most of the available VRAM. Enable --flash-attn to speed up attention calculations. With 3.7GB VRAM used by the model, you have 4.3GB left for context, allowing for a practical context window of around 100,000 tokens.

Troubleshooting

Out of memory error during inference

Reduce the number of --n-gpu-layers to 24 or 16 to free up more VRAM for context.

Slow token generation rate

Ensure that --flash-attn is enabled and that your CUDA drivers are up to date.

Model fails to load

Verify the integrity of the downloaded model file and try re-downloading it.

Alternative runtimes

If you prefer a different runtime, consider LM Studio for a GUI-based approach, llama.cpp for more fine-grained control over optimizations, or Jan for a lightweight alternative. Choose these runtimes if you need specific features not available in Ollama, such as advanced quantization options or custom model modifications.
