There is a new stable overclockable kernel in extras-testing. Installation is very simple: install the package kernel-flasher-maemo (section system in HAM), shutdown and cold boot. There's no need for reflashing etc. It requires firmware PR1.1 or newer. The default limit is at stable 600MHz. This is the same setting as the stock kernel and is safe. This kernel makes it possible dynamically change the maximum frequency up to 1.2GHz (supported frequencies are 250,500,550,600,700,750,800,850,900,950,1000,1100, 1200MHz) WARNING: Overclocking may damage your device and is at your own risk! You can manually increase the limit until your device fries using, e.g. for 600MHz Code: sudo gainroot echo 600000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq The last line shows which value was actually set. This setting takes effect immediately and is cleared with the next reboot. To permanently fix the limit edit the scaling_max_freq setting in /etc/pmconfig (using vi). WARNING: Permanent overclocking is very dangerous! Apart from overclocking, this kernel has a lot of other features (2.6.28.10, PR1.2 SDK patches etc) see http://talk.maemo.org/showthread.php?t=43420 It also retains the version info in Settings -> Product info. If it works well for you, please vote at http://maemo.org/packages/package_in....6.28-maemo19/ PS: 125MHz is deliberately not included, see http://talk.maemo.org/showpost.php?p...&postcount=141 Good luck!
