can it run
Comfortably. 256GB of memory against a 33GB working set leaves headroom for context, the OS, and anything else you're running.
weights 26GB + KV cache 0.5GB at 4k context vs ~32GB usable → tight. 26.5 of 32 GB usable — keep context modest
computed roofline: 1792 GB/s × 0.55–0.80 efficiency window / 3.9GB (Q4_K_M) — bands, never points.
MoE: file is 26GB (that decides fit) but only ~1.05B of experts activate per token (~3.9GB streamed) — band below is the active-expert estimate, optimistic; community MoE rows run several× the naive bandwidth math
