Quick Answers
- How much VRAM does Deepseek Ocr 3B Q5 need?
- Deepseek Ocr 3B Q5 needs about 6GB minimum VRAM and 16GB optimal VRAM for a safer local run target.
- Can Deepseek Ocr 3B Q5 run on an RTX 3090 24GB?
- Yes. Deepseek Ocr 3B Q5 fits comfortably on an RTX 3090 24GB target with 16GB optimal VRAM.
- What is the Ollama command for Deepseek Ocr 3B Q5?
- Use ollama run deepseek-ocr:3b-bf16. Check the Ollama tag deepseek-ocr:3b-bf16 before running.
- What is the approximate Ollama model size for Deepseek Ocr 3B Q5?
- Deepseek Ocr 3B Q5 uses the deepseek-ocr:3b-bf16 Ollama tag. Treat the Q5 3 profile as smaller than the runtime VRAM budget; use 6GB minimum VRAM and 16GB optimal VRAM as the safer sizing numbers.
- How much system RAM does Deepseek Ocr 3B Q5 need in Ollama?
- Plan for at least 32GB system RAM alongside 6GB minimum VRAM and 16GB optimal VRAM. More RAM helps if layers spill to CPU or if you run multiple models.
- What is the RAM vs VRAM requirement for Deepseek Ocr 3B Q5?
- Deepseek Ocr 3B Q5 should be sized by GPU VRAM first: 6GB minimum and 16GB optimal. System RAM should be at least 32GB so Ollama has room for CPU-side layers, context, and the surrounding app process.
- What is Deepseek Ocr 3B Q5 VRAM usage on an RTX 3090?
- Deepseek Ocr 3B Q5 is comfortable for an RTX 3090 24GB target. The page estimates 6GB minimum and 16GB optimal VRAM, with spill risk marked as moderate at long context.
- Which LocalVRAM profiles share the deepseek-ocr:3b-bf16 Ollama tag?
- LocalVRAM tracks these profiles for the same Ollama tag or model family: Deepseek Ocr 3B Q5 (Q5, 6GB min/16GB optimal); Deepseek Ocr 3B Q4 (Q4, 4GB min/14GB optimal); Deepseek Ocr 3B Q8 (Q8, 10GB min/20GB optimal); Deepseek Ocr 3B FP16 (FP16, 16GB min/28GB optimal). Use the table on this page to compare quantization and VRAM targets before choosing a run command.
- Is Deepseek Ocr 3B Q5 benchmark data measured or estimated?
- Deepseek Ocr 3B Q5 currently uses estimated baseline anchors on this page. Verified benchmark data will replace the estimate after a local hardware run is available.
Ollama Model Size and RAM Notes
| Ollama tag | deepseek-ocr:3b-bf16 |
|---|---|
| Run command | ollama run deepseek-ocr:3b-bf16 |
| Model size guidance | Q5 quantization, 3 profile; size runtime by VRAM, not download size alone |
| Runtime VRAM target | 6GB minimum, 16GB optimal |
| System RAM planning | 32GB or more when running this tag locally with Ollama |
Download size alone is not a safe runtime budget. Runtime memory also includes KV cache, context length, and GPU layer placement.
Ollama RAM vs VRAM Requirements
| GPU VRAM usage estimate | 6GB minimum / 16GB optimal |
|---|---|
| System RAM requirement | 32GB or more for Ollama runtime headroom |
| RTX 3090 24GB fit | Comfortable |
| CPU spill risk | Moderate at long context |
| Context warning | Longer context increases KV cache memory, so real VRAM usage can exceed short-prompt estimates. |
For Ollama, VRAM is the first fit check. System RAM matters when layers spill to CPU, when context grows, or when the local app stack runs beside the model.
Available Tag Variants and VRAM Targets
| Profile | Quantization | VRAM target | Ollama tag |
|---|---|---|---|
| Deepseek Ocr 3B Q5 | Q5 | 6GB min / 16GB optimal | deepseek-ocr:3b-bf16 |
| Deepseek Ocr 3B Q4 | Q4 | 4GB min / 14GB optimal | deepseek-ocr:3b-bf16 |
| Deepseek Ocr 3B Q8 | Q8 | 10GB min / 20GB optimal | deepseek-ocr:3b-bf16 |
| Deepseek Ocr 3B FP16 | FP16 | 16GB min / 28GB optimal | deepseek-ocr:3b-bf16 |
Ollama library tags often group multiple quantization choices under one model family. LocalVRAM separates them into VRAM profiles so you can pick the right local target.
