FAQ
Can the NVIDIA GTX 1650 run Gemma 3 4B?
Yes. The NVIDIA GTX 1650's 4.0GB of VRAM is enough to run Gemma 3 4B at Q5_K_S quantization (4.0GB required).
What's the best quantization to use?
Q5_K_S is the highest-precision quantization that fits in your 4.0GB. It uses about 4.0GB of memory and 5.5GB recommended for comfortable inference.
What if I need more headroom for context length?
KV cache memory grows with context length. The numbers above assume a baseline 2K-4K context. For long-context use (32K+), add another 2-6GB depending on the model architecture.
