# Can I run Command R 35B on Nvidia GeForce RTX 3090 (24GB)?

Updated: 2026-06-15

**Yes, but tight.** Fits at Q4_K_M (~22.3 GB of ~23 GB usable) but with little headroom, close other apps.

- Model: 35B, Q4_K_M 20.05 GB
- Device: 24 GB vram, ~23 GB usable for weights
- Needs ~22.3 GB at Q4_K_M; recommended quant: Q4_K_M
- Best tool on Windows: LM Studio
- Command: `ollama run command-r:35b`

Estimate. Method: weights + KV cache + ~0.8GB overhead. Sources: https://ollama.com/library/command-r, https://ollama.com/library/command-r/tags, https://huggingface.co/bartowski/c4ai-command-r-v01-GGUF, https://huggingface.co/CohereForAI/c4ai-command-r-v01.
