can it run
Comfortably. 24GB of memory against a 4GB working set leaves headroom for context, the OS, and anything else you're running.
weights 1.4GB + KV cache 0.44GB at 4k context vs ~24GB usable → full. 1.8 GB needed of 24 GB usable — headroom for context
computed roofline: 672 GB/s × 0.48–0.72 efficiency window / 1.4GB (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).
