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

TL;DR

Run Llama 3.1 8B Instruct on an NVIDIA GeForce RTX 4070 SUPER with Grade S performance, using the Q5_K_M quantization for ~84 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 525.60 or later, and CUDA 11.8 or later installed.

Expected performance

You can expect the model to run at approximately 84 tokens per second with 5.8GB of VRAM in use, leaving 6.2GB of VRAM for context. This allows for a practical context window of up to 100,000 tokens, making it suitable for long-form text generation and complex tasks.

1. Install runtimeOllama

pip install ollama
ollama init

2. Download the model

Download the Q5_K_M quantized model, which is 5.3GB in size, from the Hugging Face repository.

ollama pull bartowski/Meta-Llama-3.1-8B-Instruct-GGUF:Meta-Llama-3.1-8B-Instruct-Q5_K_M.gguf

3. Run it

ollama run Meta-Llama-3.1-8B-Instruct-Q5_K_M.gguf
ollama chat --model Meta-Llama-3.1-8B-Instruct-Q5_K_M.gguf

4. Optimize for RTX 4070 SUPER

For optimal performance on the NVIDIA GeForce RTX 4070 SUPER with 12GB VRAM, use the --n-gpu-layers flag to offload layers to the GPU. Set --n-gpu-layers to 32 to balance memory usage and speed. Enable flash attention with --flash-attn to reduce memory usage and improve performance. With 5.8GB VRAM used by the model, you have 6.2GB of headroom for context, allowing for a practical context window of up to 100,000 tokens.

Troubleshooting

Out of memory error during inference

Reduce the number of GPU layers with --n-gpu-layers 16 or lower, or enable flash attention with --flash-attn to optimize memory usage.

Slow token generation rate

Ensure that the latest NVIDIA drivers and CUDA are installed, and try enabling flash attention with --flash-attn to improve performance.

Model fails to load

Verify that the model file is correctly downloaded and not corrupted. Try re-downloading the model using the 'ollama pull' command.

Alternative runtimes

Alternative runtimes include LM Studio, llama.cpp, and Jan. LM Studio is a good choice for a graphical interface, while llama.cpp offers more control over low-level optimizations. Jan is lightweight and suitable for quick prototyping. Choose based on your specific needs, such as GUI support or fine-grained control over model parameters.
