can it run
Comfortably. 128GB of memory against a 24GB working set leaves headroom for context, the OS, and anything else you're running.
weights 18.6GB + KV cache 0.38GB at 4k context vs ~126GB usable → full. 19.0 GB needed of 126 GB usable — headroom for context
computed roofline: 256 GB/s × 0.60–0.85 efficiency window / 1.9GB (Q4_K_M) — bands, never points.
MoE: file is 18.6GB (that decides fit) but only ~3B of experts activate per token (~1.9GB streamed) — band below is the active-expert estimate, optimistic; community MoE rows run several× the naive bandwidth math
