# Can I run Yi 1.5 34B on AMD Radeon RX 7900 XTX (24GB)?

Updated: 2026-06-15

**Yes, but tight.** Fits at Q4_K_M (~21.4 GB of ~23 GB usable) but with little headroom, close other apps.

- Model: 34B, Q4_K_M 19.24 GB
- Device: 24 GB vram, ~23 GB usable for weights
- Needs ~21.4 GB at Q4_K_M; recommended quant: Q4_K_M
- Best tool on Windows: LM Studio

Estimate. Method: weights + KV cache + ~0.8GB overhead. Sources: https://huggingface.co/bartowski/Yi-1.5-34B-Chat-GGUF, https://huggingface.co/01-ai/Yi-1.5-34B-Chat.
