Hello I think you don't even need to go 'back' to boot frequency. I suggest using powerd(8) to save some power and lower the temperature. Put it in /etc/rc.conf : powerd_enable="YES" powerd_flags="-a adp -m 800" Ofc flags can be tuned to your needs. Powerd will be watching your system load and change freq dynamically depends on how heavy it is. Little off-topic: In my case i use Intel Core i5 2500k overclocked from 3.3k to 4.2k in bios, but in FreeBSD dev.cpu.0.freq = 4101 dev.cpu.0.freq_levels: 4101/300000 4000/300000 3900/300000 3800/300000 3700/300000 3600/300000 3500/300000 3400/300000 3300/300000 3200/300000 3100/300000 3000/300000 2900/300000 2800/300000 2700/300000 2600/300000 2500/300000 2187/262500 1875/225000 1600/91000 1400/79625 1200/68250 1000/56875 800/45500 600/34125 400/22750 200/11375 not something around 4200... i can live with it, but only wondering why its lower than bios settings ?
