Thanks! 400 Points more on first try and still testing.
Could you share yours daily use cpu parameters ?
For example
1300 x MPU 108 1420
1100 x MPU 108 1380
.....
or just print screens from trickstar mod or any other cpu app.
I'm curies about battery level too.
Other thing on mys Milestone2 i have only 4 CPU Frequency step with custom changeable example: originaly was 1000,800,600,300 best for my 1200,900,500,300
On Droid 4 apps shows that I have more then 10 on Lucid Kernel
Does cpu governors use all of that steps ?
If there are only few of them can I and should I change those steps ?
These are my current settings. I'm still working on them because I adjust them then use the phone for 2 full days / charges to test the stability, not every stepping is adjusted completely down - I adjusted/tested the middle voltages in groups and only adjusted the top/bottom voltages individually. There's no quick way to test them because they'll test perfectly in a CPU stress test app then within 5min of browsing the device will reboot. These particular settings have been stable for a few days. I could not get even 1443mhz stable what so ever, even after adding +75 to all voltage steps, so maybe 1.4ghz is closer to a realistic limit.
Also the voltages on this device/kernel seem to have a limit of how low you're allowed to set it. I'm not sure if this is an artificial limit or a limit of the hardware, but 952 is the lowest voltage available for 300mhz even though the device could likely undervolt far more at this frequency. Since 100 and 200 also use the same 952 voltage, there is zero point in setting the minimum frequency to anything lower than 300, as they all use the same voltage.

The CPU govenor uses all steps provided you're using ktoonservative. I found I couldn't use most other governors because they would freeze the device (ie: switching CPU governor Interactive would freeze the device, switching the I/O governor from deadline to sioplus freezes, etc). There is lots to adjust in the ktoonservative governor for performance/battery life.
I'm currently using these settings right now with good results as a balance between battery life and performance:
up_threshold 80
up_threshold_hotplug 85
down_threshold 30
down_threshold_hotplug 25
sampling_down_factor 10
sampling_rate 35000
sampling_rate_screen_off 30000
freq_step 1
disable_hotplugging 0
freq_step decides how much the CPU ramps up, a setting of "1" ensures it uses all frequencies. If you use "20" it'll increase the frequency to the closest 20% each time instead of closest 1%. Set to 100 and the governor works identical to the "ondemand" govenor (ie: CPU will go straight from lowest to highest speed). The thresholds have to do with how much % the CPU utilization has to be at before it will increase or decrease the frequency, so lower numbers can increase responsiveness by having the CPU increase it's speed quicker.
