can it run
Comfortably. 128GB of memory against a 4GB working set leaves headroom for context, the OS, and anything else you're running.
weights 2.6GB + KV cache 0.56GB at 4k context vs ~126GB usable → full. 3.2 GB needed of 126 GB usable — headroom for context
computed roofline: 273 GB/s × 0.25–0.65 efficiency window / 2.6GB (Q4_K_M) — bands, never points. Small models (under ~4.5B) run BELOW these bands — kernel-launch overhead keeps them from saturating bandwidth (measured against community medians, 09-06).
