Is it possible to change the governor on the rom image before flashing or change it post flashing (via PC or inside the rooted phone) and maintaining it that way after unrooting?
I'd like to change it to save battery and maintain low temps, since my CPU reaches 60ºC at the procesor and 45ºC at the battery (being quite hot to the touch).
I get those temps by playing pokemon go, and since it doesn't work with root, I need a way to permanently modify the freq and or governor after removing root/rebooting

Thread title says it all. Please answer me
Firstly, no its not safe to run it at 1130MHz all the time. Even, It's not advisable to run at 998MHz all the time. It gets extremely hot. The voltage at 998MHz is high and the voltage and heat is what kills a processor. Also stability might be a issue. It MIGHT be possible to run it at 1130MHz but that would be selectively. It can be done by setting profiles in set CPU. Thing is, DON'T do it ALL the time, BUT SELECTIVELY. use the setting ON DEMAND. also, try to set temperature dependent profiles.
Hope this helps
how I overclok it?
ok so im running the STOCK GB but im rooted and have been running gingertiny 9/29 ran into rebooting issues.. phone constently reboots after 20 mins of use. usually when this happened before like on stock kernels the battery temp would rise up to 104 but i kept eyes on the temp and it never goes over 78.4 F
not overclocking cpu im actually running at about 625 mhz but issue still occurs
SO with that being said i need help finding either a better kernal or trying to find solutions with this one.
i went back to complete stock and rooted to see if i still have this issue
any help will do thanks!
These questions belong in the Q/A section. This has zero relevance to development.
Now:
1) pull the battery then place it back into your phone.
2) Charge it awhile to make sure you haven't dropped a considerable charge during the bootloops.
3) Turn your phone on and move your clock speed towards 998400 (stock clock speed) via setcpu or however you underclocked.
This bootloop is likely due to you being underclocked so low. If you want, flash Tiny's latest kernel from 9/29/2011 to bring yourself up to date.
Was your min clock speed underclocked below the stock 245000? I had random reboot issues when I underclocked my min to 128000.
Having your max_freq set at 628 or whatever it was shouldn't cause reboot issues. You're phone should be rock-solid stable at a speed like that. I'd suggest taking a look at your voltages.
I've never run that kernel so I'm not familiar with what the voltage table looks like, but it might very well be that your voltage is too low. If your max_freq were higher, the transition through that clock freq would probably be too brief to cause an issue. I don't know if that kernel has sysfs enabled, but if it does, upping the voltage at that step .25 volts should cure it.
Min speed was at 628 even switching back to stock kernel still having issues I'm not sure what can be the issue I only last few mins playing any games or watching anything all speeds are stock

Sounds like it's time to start wiping stuff.
Does anybody know what the ondemand governor uses as it's default screen off settings. By that I mean if I have profiles disabled in setcpu and just allow the ondemand governor to determine frequencies and I leave the max min freq's at default values, then what happens when the screen is turned off?
I know the cpu will eventually go into deepsleep but there are inconsistencies.
If I dont use setcpu and just allow the default kernel settings (im on doomlords btw) to determine the frequencies, then when I turn the screen on after leaving the phone for a while, the cpu speeds up very quickly and the system becomes responsive before I can ever notice.
If I use setcpu however, with a screen off profile set to ondemand, max 245, min 120, then it still takes achieves deepsleep as often as not using setcpu but there is a noticeable lag and stutter for about 5-10 seconds as I turn the screen on to use it again.
Does anyone have any idea;
A) Why this happens?
B) What is the default screen off behaviour for the ondemand governor on doomlords kernel.
you may need a program like system monitor to record your % of cpu activity, im on stock rom and i have it at 100 - 300 mhz max when screen off, i used the program while im asleep to see if there was issues but there was none or lag when the screen turned on
there isnt any inconsistency with mine,but then again i removed alot of the programs i dont use to have very few programs running in the background,playing music with this setting doesn't cause issues
i havent read alot into his kernal yet,guess you wait till someone that has more knowlege in his rom.
[v03 onwards] added new CPU governors:

I recently have bought a Defy plus.
Stock 2.3.4 ROM used so far with LauncherPro.
Doing OK with battery life so far, but now starting to look at the CPU over/underclock capabilities. Started with Antutu CPU Master and CPUTuner also.
One thing I haven't seen as yet is the ability to underclock clock below the min 300MHz.. or even whether this makes sense. I guess undervolting is the other option, but perhaps someone can guide me here.
use setvsel to oc/uv, thats the easiest and best app imo. although underclocking your phone below 300mhz may cause instability and makes the phone wake up much slower in my experience.

I agree with zakoo2: Going below 300 will not be a good idea and it will most likely not improve your battery life in any significant way:
My Defy is running between 300-600Mhz and right now the LCD screen is the biggest consumer: Changing the (auto-)brightness settings in CM7 will do *much* more to your battery life than going below 300mhz.
What really helps saving battery life: use setvsel and leave the minimum clockspeed at 300MHz, but set a vsel value of about 20 for it, then scroll down and enable "limit to vsel1 while screen is off".
Also, going below 300MHz will probably make the phone sluggish when waking up from sleep like if a call comes.

im just change from 300mhz to 330mhz lowest. 300mhz will make my defy+ lag when got incoming call. im using smartass govenor.
I heard some guy out there got 80 MHz and running, but I'm not sure of it.
As people said, clocks lower then 300 MHz would make your phone run horribly while waking up (i.e., it would take a long time for the screen to turn on when receiving a call, and you would probably miss it most of the times). Setting 300 as VSel1 and limitting to it while screen is off (2nd-init enabled bootmenu has this option, and downloading SetVSel - free at Android Market - will also do the trick if you have a rooted, but stock ROM) will help you save a lot of juice. Using a lightweight launcher (I personally recommend MetroUI or Zeam) also boosts up batt saving. Last, but not least, setting brightness to auto or minimum (using frosted/mat screen protectors will help a lot while using the phone under direct sunlight) also saves loads of charge.
Obviously, using a light ROM (I think Barebones may be a good option, though I think it's not suitable for me, but it's a personal matter) and calibrating your battery in a monthly basis (via manual calibration - you can find how to do so by googling -, wiping batt stats in custom recovery and/or using the batt calibration app included in most ROMs - but also free at AM) also help.
As the title says, I have this problem where the big cluster frequency stays at 2361MHz and doesn't drop down to its idle frequency. It occasionally goes down to about 2000MHz, but rises back to its max frequency within a second.
I tried clean flashing OOS 5.0.3 (zip from OP website), I'm not rooted, no custom kernel (all stock basically). It seems to happen after a few hours and not as soon as the device is turned on.
I'm wondering if it's a kernel problem/bug or something else (play services for example). I'd really like to know if anyone else experienced it and if anyone got it fixed.
are you using a custom kernel or root?
if so download elementalx or any kernel editing tool and change the cluster back to 300mhz
i find i have to do this for the cluster to scale back down
You can try New Kernel by @jgcaap.
It's probably the best kernel for this phone with amazing performance/smoothness/battery.
In the latest build the idle freqs are back to normal after OnePlus mess/faulty optimisation in OB2.

If your CPU doesn't idle it can also be an app running in background and hogging cpu time.
