can it run
Comfortably. 32GB of memory against a 18GB working set leaves headroom for context, the OS, and anything else you're running.
weights 14GB + KV cache 0.19GB at 4k context vs ~30GB usable → full. 14.2 GB needed of 30 GB usable — headroom for context
computed roofline: 120 GB/s × 0.80–1.00 efficiency window / 2.1GB (Q4_K_M) — bands, never points.
MoE: file is 14GB (that decides fit) but only ~3B of experts activate per token (~2.1GB streamed) — band below is the active-expert estimate, optimistic; community MoE rows run several× the naive bandwidth math
