Can I run Qwen3 14B on the GeForce RTX 4060?
Runs slowlyQ4_K_M does not fit fully in VRAM, so 3.5 GB of the weights run from system RAM: Runs slowly, est. 8.1 tok/s (6.5–9.7, calibrated estimate ±20%). Q2_K (heavy quality loss) would reach Runs well, est. 23.3 tok/s (18.7–28.0, calibrated estimate ±20%).

How to run it
Commands for the Q4_K_M file. Both tools download from Hugging Face on first run.
File: Qwen3-14B-Q4_K_M.gguf (9.00 GB) from unsloth/Qwen3-14B-GGUF.
llama-server -hf unsloth/Qwen3-14B-GGUF:Q4_K_M -c 8192 -ngl 24 -fa on- -ngl 24 puts 24 of 40 layers on the GPU; if VRAM overflows, lower it by 1–2.
- -fa on enables flash attention (needed for KV cache quantization).
- --cache-type-k q8_0 --cache-type-v q8_0 shrinks the KV cache to 0.72 GB at 8k context.
PowerShell (quit the Ollama tray app first):
$env:OLLAMA_CONTEXT_LENGTH="8192"; ollama serve
ollama run hf.co/unsloth/Qwen3-14B-GGUF:Q4_K_M- Ollama defaults to 4k context on GPUs under 24 GB. Set OLLAMA_CONTEXT_LENGTH when starting the server, or /set parameter num_ctx inside the chat.
- Ollama splits layers between GPU and CPU automatically.
/set parameter num_ctx 8192

Frequently asked questions
Can I run Qwen3 14B on the GeForce RTX 4060?
Q4_K_M does not fit fully in VRAM, so 3.5 GB of the weights run from system RAM: Runs slowly, est. 8.1 tok/s (6.5–9.7, calibrated estimate ±20%). Q2_K (heavy quality loss) would reach Runs well, est. 23.3 tok/s (18.7–28.0, calibrated estimate ±20%). Q4_K_M needs 10.5 GB at 8k context; this setup has 7.4 GB of usable memory and 28.0 GB of free system RAM.
How much context can Qwen3 14B use on the GeForce RTX 4060?
At Q4_K_M the verdict stays Runs slowly up to 32k context with an f16 KV cache (5.4 GB of KV) and up to 32k with a q8_0 KV cache (2.9 GB). The model supports up to 32k.
Which quant should I use, and how fast is it?
Q4_K_M (9.00 GB) is the recommended balance: Runs slowly, est. 8.1 tok/s (6.5–9.7, calibrated estimate ±20%). The largest tracked file that still gets Runs slowly is Q8_0 (15.70 GB), est. 3.6 tok/s (2.9–4.3, calibrated estimate ±20%).
Speeds are estimates from memory bandwidth, calibrated against public benchmarks, and each one comes with an error band and a confidence label. Real results vary with drivers, backend, context length and thermals.
