[updated.15.02][App]Overclocking/Undervolting Helper

[inteks]

I'm pretty sure lower is possible, but you need to change another file to display this - it's described at the overclock module site I think.
I can do 300/26 but only at 250MHz vsel 22 is stable.

Other values are:
600/32 and 800/44 or 1000/56.

below 300 does not work (on my defy) ....

you can check with

adb shell
cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq

Change the first thread! "planned" are update 4 right?

your right , thx

I may be able to underclock <300Mhz

cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies
gives me: 800000 600000 250000


after applying the following script in GScript:

echo 38 > /proc/overclock/max_vsel
echo 800000 > /proc/overclock/max_rate
echo 1 250000000 23 > /proc/overclock/mpu_opps
echo 2 600000000 33 > /proc/overclock/mpu_opps
echo 3 800000000 38 > /proc/overclock/mpu_opps
echo 0 800000 > /proc/overclock/freq_table
echo 1 600000 > /proc/overclock/freq_table
echo 2 250000 > /proc/overclock/freq_table
cat /proc/overclock/mpu_opps

Battery life is excellent with these settings. I'm at 70% after 41 hours of normal phone usage. With stock freq. and voltages I was at 50% after simliar usage.

However:
cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq
never gives me 250Mhz. Only 600 or 800Mhz.

So is it working or not?

do
echo 250000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq

and run a benchmark or run stabilitytest (market)
it should show ca. 250 bogomips

if it shows 600 or if you get same benchmarkresults on 250 and 600 it does not work....

 

[inteks]

update setvsel to v6.

added a option to run stabilitytest. after i run it on my defy i had to push up the vsels for 700 & 1100 but its good to know its stable....

but i could lower the vsel for 300 and thats the cpu freq while is display off

It gives me exactly 299.11 bogomips for 250Mhz max
Does this mean the Defy actually runs at 299.11Mhz and not 250?

So I managed to underclock only 0.89 Mhz

it looks like it runs @300 but cant display it correct because of the wrong settings.

How long is everyone letting the stability test run? 5 hours seems rather extreme for a phone

10 mins (on the heater to simulate summer conditions )

Toasty Have you hit 40C yet?

inteks, you probably already know but setvsel v6 thinks my current clock speed hits a max of 1MHz (when it should be 1000MHz)

 

[Sorensiim]

Any chance for Froyo support?

 

[inteks]

Any chance for Froyo support?

although we no longer need milestoneoverclock because setvsel loads overclock.ko himself
is it still dependent on it
if milestoneoverclock support froyo on defy setvsel support it too

Great app! Using it couple of days, no problems at all. 2.34.1 Build

Thanks!

If possible could you add an option for a certain max clock speed once your battery hits a certain level?

Thanks.

my defy runs 300/600/800 with 20/30/40 and stablity test didnt find errors after testing each frequency for 1h. nevertheless every few days i get errors or apps act up.

from overclocking pcs i know, even if voltages are fine for specific freqencies, the moment of changing states is critical.

so maybe the easiest way would be: find the vsel were errors appear after some minutes and add 4 or more to the vsel to be safe.

This is getting beautiful, he is doing a great job.
