Hardware: RTX 3090 24GB · Model: DeepSeek R1 Distill Qwen 14B
RTX 3090 24GB has 24 GB of VRAM and 936 GB/s of memory bandwidth. The checker holds back 0.5 GB of VRAM for the driver and assumes 16 GB of system RAM, so fast memory usable by Ollama is 23.5 GB. Partial offload may also use 60% of that system RAM. DeepSeek R1 Distill Qwen 14B (14.8B, DeepSeek) at Q8_0 is a 16 GB download and needs 17.3 GB with headroom for about 8k tokens.
