Quick Answers
- How much VRAM does DeepSeek-V3 67B Q4 need?
- DeepSeek-V3 67B Q4 needs about 38GB minimum VRAM and 48GB optimal VRAM for a safer local run target.
- Can DeepSeek-V3 67B Q4 run on an RTX 3090 24GB?
- Not as a comfortable local target. DeepSeek-V3 67B Q4 needs about 38GB minimum and 48GB optimal VRAM, so cloud or larger local GPUs are safer.
- What is the Ollama command for DeepSeek-V3 67B Q4?
- Use ollama run deepseek-v3:67b. Check the Ollama tag deepseek-v3:67b before running.
- What is the approximate Ollama model size for DeepSeek-V3 67B Q4?
- DeepSeek-V3 67B Q4 uses the deepseek-v3:67b Ollama tag. Treat the Q4 67 profile as smaller than the runtime VRAM budget; use 38GB minimum VRAM and 48GB optimal VRAM as the safer sizing numbers.
- How much system RAM does DeepSeek-V3 67B Q4 need in Ollama?
- Plan for at least 64GB system RAM alongside 38GB minimum VRAM and 48GB 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-V3 67B Q4?
- DeepSeek-V3 67B Q4 should be sized by GPU VRAM first: 38GB minimum and 48GB optimal. System RAM should be at least 64GB so Ollama has room for CPU-side layers, context, and the surrounding app process.
- What is DeepSeek-V3 67B Q4 VRAM usage on an RTX 3090?
- DeepSeek-V3 67B Q4 is not recommended for an RTX 3090 24GB target. The page estimates 38GB minimum and 48GB optimal VRAM, with spill risk marked as high without a larger GPU or cloud.
- Which LocalVRAM profiles share the deepseek-v3:67b Ollama tag?
- LocalVRAM tracks these profiles for the same Ollama tag or model family: DeepSeek-V3 67B Q4 (Q4, 38GB min/48GB optimal); DeepSeek-V3 67B Q5 (Q5, 40GB min/50GB optimal); DeepSeek-V3 67B Q8 (Q8, 44GB min/54GB optimal); DeepSeek-V3 67B FP16 (FP16, 50GB min/62GB optimal). Use the table on this page to compare quantization and VRAM targets before choosing a run command.
- Is DeepSeek-V3 67B Q4 benchmark data measured or estimated?
- DeepSeek-V3 67B Q4 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-v3:67b |
|---|---|
| Run command | ollama run deepseek-v3:67b |
| Model size guidance | Q4 quantization, 67 profile; size runtime by VRAM, not download size alone |
| Runtime VRAM target | 38GB minimum, 48GB optimal |
| System RAM planning | 64GB 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 | 38GB minimum / 48GB optimal |
|---|---|
| System RAM requirement | 64GB or more for Ollama runtime headroom |
| RTX 3090 24GB fit | Not recommended |
| CPU spill risk | High without larger GPU or cloud |
| 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-V3 67B Q4 | Q4 | 38GB min / 48GB optimal | deepseek-v3:67b |
| DeepSeek-V3 67B Q5 | Q5 | 40GB min / 50GB optimal | deepseek-v3:67b |
| DeepSeek-V3 67B Q8 | Q8 | 44GB min / 54GB optimal | deepseek-v3:67b |
| DeepSeek-V3 67B FP16 | FP16 | 50GB min / 62GB optimal | deepseek-v3:67b |
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.
