DeepSeek R1 Distill Qwen 32B (Q6_K) — 15.4 GBon NVIDIA RTX 5070 Ti

Q6_K NVIDIA RTX 5070 Ti

Overview

DeepSeek R1 Distill Qwen 32B is a 32.76B parameter dense language model by DeepSeek, with code, multilingual, thinking, tool-calls capabilities. It supports a context window of up to 131,072 tokens.

DeepSeek R1 Distill Qwen 32B is a 32.76-billion-parameter dense transformer from DeepSeek, distilled from the larger R1 reasoning model into a Qwen-based architecture. It excels at chain-of-thought reasoning, code generation, and multilingual tasks with built-in thinking capabilities. Compared to standard 30B-class instruct models, it provides stronger logical and mathematical reasoning. The model supports nine languages and a 128K context window, making it suitable for developers and researchers who need reasoning-focused inference on mid-range GPU setups.

At Q6_K quantization (high quality tier), the model weighs 25.04 GB. This exceeds the 16 GB of VRAM on NVIDIA RTX 5070 Ti. Inference is still possible via CPU offload or memory-mapped loading from disk, but expect significantly reduced performance.

Hardware Requirements

Model size	25.04 GB
VRAM available	16 GB
VRAM used	15.4 GB
Min RAM required	11 GB
GPU layers	36 / 64
Context size	512
Backend	cuda13

Performance Notes

Reduced performance

28 of 64 layers run on CPU. Your system needs at least 11 GB RAM. If system RAM is insufficient, data will be read from disk on demand, with significant performance impact.

Shorter conversations

Context size has been reduced due to memory constraints. This may affect the model's ability to handle long conversations.

Frequently Asked Questions

How much VRAM does DeepSeek R1 Distill Qwen 32B (Q6_K) need?

The Q6_K quantization of DeepSeek R1 Distill Qwen 32B requires 25.04 GB. 36 of 64 layers fit in the 16 GB of VRAM on NVIDIA RTX 5070 Ti; remaining layers are offloaded to CPU.

Can I run DeepSeek R1 Distill Qwen 32B on NVIDIA RTX 5070 Ti?

Yes, with reduced performance. NVIDIA RTX 5070 Ti can run DeepSeek R1 Distill Qwen 32B (Q6_K), but only 36 of 64 layers fit in VRAM. The rest are offloaded to CPU.

What is quantization?

Quantization reduces a model's numerical precision from its original floating-point format to a more compact representation. This shrinks the file size and VRAM footprint, making it possible to run large models on consumer hardware. The trade-off is a small reduction in output quality. Q6_K compresses DeepSeek R1 Distill Qwen 32B from its original size down to 25.04 GB.

What quantization should I choose for DeepSeek R1 Distill Qwen 32B?

Q6_K is a high-quality quantization. Higher-quality quants (Q8, Q6) preserve more model accuracy but need more VRAM. Lower quants (Q4, Q3, Q2) reduce VRAM usage at the cost of some quality. Choose based on your available hardware and quality requirements.

What is flash attention and why is it enabled?

Flash attention is a memory-efficient algorithm that speeds up the attention mechanism in transformer models. It reduces VRAM usage during inference by avoiding the materialisation of the full attention matrix. For DeepSeek R1 Distill Qwen 32B on NVIDIA RTX 5070 Ti, flash attention is enabled to maximise context length and throughput within the available 16 GB of VRAM.

Why are some layers offloaded to CPU?

NVIDIA RTX 5070 Ti has 16 GB of VRAM, but DeepSeek R1 Distill Qwen 32B (Q6_K) requires approximately 25.04 GB. Only 36 of 64 layers fit in VRAM; the remaining layers run on CPU, which is slower but still functional.

How do I run DeepSeek R1 Distill Qwen 32B (Q6_K) with Ollama?

Run ollama run deepseek-r1:32b-qwen-distill-q6_k to start DeepSeek R1 Distill Qwen 32B (Q6_K). Ollama handles downloading the model weights automatically on first run.
