Setup tutorial: OLMoE 1B-7B on RTX 5090
AI-generated, GPU-specific. Verified commands for your exact hardware.
The OLMoE 1B-7B model runs at Grade S on the NVIDIA GeForce RTX 5090 with Q8_0 quantization, achieving ~183 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 525.60.13 or later) with CUDA 11.8 installed.
Expected performance
You can expect the OLMoE 1B-7B model to run at approximately 183 tokens per second with 7.3GB VRAM in use. Given the remaining 24.6GB of VRAM, you can achieve a practical context window of up to 4096 tokens, making it suitable for long-form text generation tasks.

ollama chat OLMoE-1B-7B-0924-Instruct-Q8_04. Optimize for RTX 5090
For optimal performance on the NVIDIA GeForce RTX 5090 with 32GB VRAM, set --n-gpu-layers to 70 to fully utilize the GPU's memory. Enable --flash-attn to speed up attention computations. With 7.3GB VRAM used by the model, you have 24.6GB of headroom for larger context windows, allowing for longer sequences without running out of memory.
Troubleshooting
Out of memory errors during inference
Reduce --n-gpu-layers to 50 or lower and decrease the context window size.
Slow inference speed
Ensure --flash-attn is enabled and update your NVIDIA drivers to the latest version.
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 offers a more user-friendly interface and is suitable for users who prefer a GUI. llama.cpp is highly optimized for CPU inference and is ideal for systems with limited GPU resources. Jan provides a web-based interface and is useful for deploying models on cloud infrastructure. For the NVIDIA GeForce RTX 5090, Ollama is recommended due to its ease of use and efficient GPU utilization.
