You should run the 'powerd' service to make it boost to max > frequency under load. Interesting, didn't know it defaults to the llower freq. On a normal 3 model (it was running at 600): dev.cpu.0.freq_levels: 1200/-1 600/-1 dev.cpu.0.freq: 1200 On another normal 3 model (it only has 1200): dev.cpu.0.freq_levels: 1200/-1 dev.cpu.0.freq: 1200 The strange thing about this difference is that the second is running a cloned image, so theoretically it should also offer 600MHz. Maybe the boards were from a different batch. The second without 600MHz is remote, so I can't do any visual inspections. -- B.Walter http://www.bwct.de Modbus/TCP Ethernet I/O Baugruppen, ARM basierte FreeBSD Rechner uvm.
