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

TL;DR

Run Qwen 2.5 14B on a NVIDIA GeForce RTX 3070 Ti with Q4_K_M quantization. Expect ~32 tok/sec and Grade C performance.

Prerequisites

Before starting, ensure you have at least 20GB of free disk space, a 64-bit version of Windows or Linux, and the latest NVIDIA drivers (version 512.15 or later) installed along with CUDA 11.2 or higher.

Expected performance

With the recommended settings, expect the model to run at approximately 32 tokens per second, using around 8.9GB of VRAM. Given the 8GB VRAM limit, you will have about -0.9GB of headroom, which may restrict the practical context window to around 100,000 tokens.

1. Install runtimeOllama

pip install ollama
ollama init

2. Download the model

Download the Qwen 2.5 14B Q4_K_M quantized model (8.4GB file) from Hugging Face.

ollama pull bartowski/Qwen2.5-14B-Instruct-GGUF:Qwen2.5-14B-Instruct-Q4_K_M.gguf

3. Run it

ollama run Qwen2.5-14B-Instruct-Q4_K_M --n-gpu-layers 12 --flash-attn --tensor-parallelism 1

4. Optimize for RTX 3070 Ti

For optimal performance on the NVIDIA GeForce RTX 3070 Ti with 8GB VRAM, use the --n-gpu-layers 12 flag to offload some layers to CPU, enable --flash-attn for efficient attention computation, and set --tensor-parallelism 1 to avoid splitting the model across multiple GPUs. This configuration helps manage the 8.9GB VRAM requirement within the 8GB limit.

Troubleshooting

Out of memory (OOM) errors during inference.

Reduce the number of GPU layers by increasing --n-gpu-layers, e.g., --n-gpu-layers 16.

Slow inference speed.

Ensure that --flash-attn is enabled and try reducing the batch size.

Model fails to load.

Verify that the model file is correctly downloaded and not corrupted. Re-run the download command if necessary.

Alternative runtimes

Consider using LM Studio for a more user-friendly interface, llama.cpp for lower-level control, or Jan for better performance on older hardware. Ollama is recommended for its ease of use and compatibility with the Qwen 2.5 14B model.
