# Can I run Qwen3 30B-A3B on AMD Radeon RX 7900 XTX (24GB)?

Updated: 2026-06-15

**Yes, but tight.** Fits at Q4_K_M (~20.7 GB of ~23 GB usable) but with little headroom, close other apps.

- Model: 30.5B (MoE, 3.3B active), Q4_K_M 18.6 GB
- Device: 24 GB vram, ~23 GB usable for weights
- Needs ~20.7 GB at Q4_K_M; recommended quant: Q4_K_M
- Best tool on Windows: LM Studio
- Command: `ollama run qwen3:30b-a3b`

Estimate. Method: weights + KV cache + ~0.8GB overhead. Sources: https://ollama.com/library/qwen3/tags, https://huggingface.co/unsloth/Qwen3-30B-A3B-GGUF, https://huggingface.co/Qwen/Qwen3-30B-A3B-GGUF, https://qwenlm.github.io/blog/qwen3/, https://lmarena.ai/leaderboard.
