Quick Answers
- How much VRAM does DeepSeek-R1 14B Q8 need?
- DeepSeek-R1 14B Q8 needs about 16GB minimum VRAM and 26GB optimal VRAM for a safer local run target.
- Can DeepSeek-R1 14B Q8 run on an RTX 3090 24GB?
- It may load on an RTX 3090 24GB because the minimum estimate is 16GB, but the safer target is 26GB. Expect tighter context or lower throughput.
- What is the Ollama command for DeepSeek-R1 14B Q8?
- Use ollama run deepseek-r1:14b. Check the Ollama tag deepseek-r1:14b before running.
- What is the approximate Ollama model size for DeepSeek-R1 14B Q8?
- DeepSeek-R1 14B Q8 uses the deepseek-r1:14b Ollama tag. Treat the Q8 14 profile as smaller than the runtime VRAM budget; use 16GB minimum VRAM and 26GB optimal VRAM as the safer sizing numbers.
- How much system RAM does DeepSeek-R1 14B Q8 need in Ollama?
- Plan for at least 64GB system RAM alongside 16GB minimum VRAM and 26GB 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-R1 14B Q8?
- DeepSeek-R1 14B Q8 should be sized by GPU VRAM first: 16GB minimum and 26GB 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-R1 14B Q8 VRAM usage on an RTX 3090?
- DeepSeek-R1 14B Q8 is borderline for an RTX 3090 24GB target. The page estimates 16GB minimum and 26GB optimal VRAM, with spill risk marked as high without a larger GPU or cloud.
- Which LocalVRAM profiles share the deepseek-r1:14b Ollama tag?
- LocalVRAM tracks these profiles for the same Ollama tag or model family: DeepSeek-R1 14B Q8 (Q8, 16GB min/26GB optimal); DeepSeek-R1 14B Q4 (Q4, 10GB min/20GB optimal); DeepSeek-R1 14B Q5 (Q5, 12GB min/22GB optimal); DeepSeek-R1 14B FP16 (FP16, 22GB min/34GB optimal). Use the table on this page to compare quantization and VRAM targets before choosing a run command.
- Is DeepSeek-R1 14B Q8 benchmark data measured or estimated?
- DeepSeek-R1 14B Q8 has a verified RTX 3090 result of 78.909 tokens/s from LocalVRAM benchmark data.
Ollama Model Size and RAM Notes
| Ollama tag | deepseek-r1:14b |
|---|---|
| Run command | ollama run deepseek-r1:14b |
| Model size guidance | Q8 quantization, 14 profile; size runtime by VRAM, not download size alone |
| Runtime VRAM target | 16GB minimum, 26GB 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 | 16GB minimum / 26GB optimal |
|---|---|
| System RAM requirement | 64GB or more for Ollama runtime headroom |
| RTX 3090 24GB fit | Borderline |
| 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-R1 14B Q8 | Q8 | 16GB min / 26GB optimal | deepseek-r1:14b |
| DeepSeek-R1 14B Q4 | Q4 | 10GB min / 20GB optimal | deepseek-r1:14b |
| DeepSeek-R1 14B Q5 | Q5 | 12GB min / 22GB optimal | deepseek-r1:14b |
| DeepSeek-R1 14B FP16 | FP16 | 22GB min / 34GB optimal | deepseek-r1:14b |
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.
