# DeepSeek R1 Distill Qwen 32B VRAM Requirements & Hardware Sizing Guide

> **Quick Summary (Answer Capsule)**: Running DeepSeek R1 Distill Qwen 32B requires 23.10 GB at Q4_K_M (4-bit), 39.47 GB at Q8_0 (8-bit), and 70.20 GB at FP16. Recommended hardware sweet spot: Dual NVIDIA RTX 3060 Rig (24GB VRAM). Scaling context past 32k tokens requires enabling FP8 KV-cache (-ctk q8_0) to prevent CUDA allocation failures.

## Memory Specifications by Precision
| Quantization Format | Precision Level | Required VRAM (8k context) | Quality Retention | Minimum Recommended GPU |
|---|---|---|---|---|
| 4-Bit (Q4_K_M) | Recommended Default | 23.10 GB | >98.2% Perplexity | Dual NVIDIA RTX 3060 Rig (24GB VRAM) |
| 8-Bit (Q8_0) | Near Lossless | 39.47 GB | ~99.9% Perplexity | Workstation / High-Tier GPU |
| 16-Bit (FP16/BF16) | Uncompressed Full | 70.20 GB | 100% Fidelity | Multi-GPU / Datacenter |

## Architectural Memory Analysis
DeepSeek R1 Distill Qwen 32B distills DeepSeek R1's reasoning capabilities into Alibaba's dense Qwen 2.5 32B architecture. Featuring 64 layers with 40 query heads and 8 GQA key-value heads (`headDim = 128`), its 4-bit Q4_K_M weights take 19.2 GB, reaching 21.64 GB total at 8k context. It brings frontier chain-of-thought math and coding reasoning to single 24GB GPUs.

## Tier 1 Free Software Optimization ($0)
Because reasoning models output long `<think>` token streams, context grows rapidly. Set `OLLAMA_FLASH_ATTENTION=1 OLLAMA_KV_CACHE_TYPE=q8_0` to halve KV growth, ensuring 32k multi-turn reasoning stays inside 23.2 GB on RTX 3090/4090.
