    FAQ: How to Adjust maximum clock speeds

    Some adams cannot handle 1.6GHz clocks which some ROMs are set by default and may not boot, so the following change should allow for it to boot.

    -connect usb to adam in cwm
    -mount /system in cwm
    -type "adb pull /system/etc/adam_preboot.sh"
    -You should now have adam_preboot.sh on your pc in current directory
    -edit adam_preboot.sh and change to the following from:
    echo 1600000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
    echo 1600000 > /sys/devices/system/cpu/cpu1/cpufreq/scaling_max_freq
    to (add this if it doesn't exist):
    echo 1000000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
    echo 1000000 > /sys/devices/system/cpu/cpu1/cpufreq/scaling_max_freq
    -now type "adb push adam_preboot.sh /system/etc/" and this will push the changed file to your Adam
    -this will change from 1.6GHz to 1.0GHz default clock.

    Adjustment can also be made after the system is up and running. The "tried and reliable" tool I use is the 'SetCPU' app (needs root). For experts, this app also supports settting low-level controls such as governor values, cpu chip voltage, etc.
