Frequently Asked Questions
- How much VRAM does Qwen3.6 35B A3B DFlash need?
Qwen3.6 35B A3B DFlash requires 21.3 GB of VRAM at Q4_K_M, or 70.3 GB at BF16. Full 262K context adds up to 3.2 GB (24.5 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 35B × 4.8 bits ÷ 8 = 21 GB
KV Cache + Overhead ≈ 0.3 GB (at 2K context + ~0.3 GB framework)
KV Cache + Overhead ≈ 3.5 GB (at full 262K context)
VRAM usage by quantization
Q4_K_M21.3 GBQ4_K_M + full context24.5 GB- Can NVIDIA GeForce RTX 4090 run Qwen3.6 35B A3B DFlash?
Yes, at Q4_K_M (21.3 GB) or lower. Higher quantizations like Q5_K_M (25.3 GB) exceed the NVIDIA GeForce RTX 4090's 24 GB.
- What's the best quantization for Qwen3.6 35B A3B DFlash?
