Quick Answers

How much VRAM does DeepSeek Coder V2 16B Q4 need?
DeepSeek Coder V2 16B Q4 needs about 18GB minimum VRAM and 28GB optimal VRAM for a safer local run target.
Can DeepSeek Coder V2 16B Q4 run on an RTX 3090 24GB?
It may load on an RTX 3090 24GB because the minimum estimate is 18GB, but the safer target is 28GB. Expect tighter context or lower throughput.
What is the Ollama command for DeepSeek Coder V2 16B Q4?
Use ollama run deepseek-coder-v2:16b. Check the Ollama tag deepseek-coder-v2:16b before running.
What is the approximate Ollama model size for DeepSeek Coder V2 16B Q4?
DeepSeek Coder V2 16B Q4 uses the deepseek-coder-v2:16b Ollama tag. Treat the Q4 16 profile as smaller than the runtime VRAM budget; use 18GB minimum VRAM and 28GB optimal VRAM as the safer sizing numbers.
How much system RAM does DeepSeek Coder V2 16B Q4 need in Ollama?
Plan for at least 64GB system RAM alongside 18GB minimum VRAM and 28GB 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 Coder V2 16B Q4?
DeepSeek Coder V2 16B Q4 should be sized by GPU VRAM first: 18GB minimum and 28GB 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 Coder V2 16B Q4 VRAM usage on an RTX 3090?
DeepSeek Coder V2 16B Q4 is borderline for an RTX 3090 24GB target. The page estimates 18GB minimum and 28GB optimal VRAM, with spill risk marked as high without a larger GPU or cloud.
Which LocalVRAM profiles share the deepseek-coder-v2:16b Ollama tag?
LocalVRAM tracks these profiles for the same Ollama tag or model family: DeepSeek Coder V2 16B Q4 (Q4, 18GB min/28GB optimal); DeepSeek Coder V2 16B Q5 (Q5, 20GB min/30GB optimal); DeepSeek Coder V2 16B Q8 (Q8, 24GB min/34GB optimal); DeepSeek Coder V2 16B FP16 (FP16, 30GB min/42GB optimal). Use the table on this page to compare quantization and VRAM targets before choosing a run command.
Is DeepSeek Coder V2 16B Q4 benchmark data measured or estimated?
DeepSeek Coder V2 16B 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-coder-v2:16b
Run command ollama run deepseek-coder-v2:16b
Model size guidance Q4 quantization, 16 profile; size runtime by VRAM, not download size alone
Runtime VRAM target 18GB minimum, 28GB 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 18GB minimum / 28GB 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 Coder V2 16B Q4 Q4 18GB min / 28GB optimal deepseek-coder-v2:16b
DeepSeek Coder V2 16B Q5 Q5 20GB min / 30GB optimal deepseek-coder-v2:16b
DeepSeek Coder V2 16B Q8 Q8 24GB min / 34GB optimal deepseek-coder-v2:16b
DeepSeek Coder V2 16B FP16 FP16 30GB min / 42GB optimal deepseek-coder-v2:16b

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.
