Zbigniew Majewski(@majewskizby):Heads up for DGX Spark owners: capping clocks with `nvidia-smi -lgc 0,2200` keeps the GB10 cooler and the clocks stable but it does NOT persist across reboots or driver resets. Wrap it in a systemd timer (OnCalendar=*:0/10) or your "capped" box quietly drifts back toward 3 GHz.
