Hello existing members, and new comers, this is a thread dedicated to people's temperatures and clock speeds on this phone. Doing this we can learn how the Desire C handles heat in certain circumstances, and if it is indeed the reason why people cannot overclock as high as others.
However I would like to state to anyone who tries any of these tips and tricks mentioned by both me and other members, we are NOT LIABLE for any damage you may cause to your device. I guessing most of you guys are aware of this, but I thought to make to clear to anyone who doesn't know these things.
To the existing fellow Desire C overclockers I have wrote some notes of which can improve the experience with your phone, they are as follows:
Use different frequencies instead of a solid one, for example:
In certain CPU management applications you can change how the CPU behaves when the phone is in a certain state, this meaning things such as; charging, low battery, sleep etc...
These adjustments are known in the android community as "profiles" there is currently one one CPU program of which I know about what can do these "profiles" and that's setCPU. (if you guys know any others pm me, or post in this thread and I will make a list of apps available)
When you use your phone for music especially files with a high bit rate (320kbps) when you lock the phone the music may stutter, or "lag" let's put it. Now I have found a way to greatly reduce this "lag" this is to go to where it states the lowest CPU frequency and turn it up from 122mhz to 2xxmhz. This fixes lag because when the clock speed is at such a low state, functions and background services such as music, sync etc... are preformed much slower, hence the "lag".
One of my main points is about the phones CPU "governor" this basically controls how android will handle your phones cores, and resources currently there are many available in the current kernels, however, as more kernels come there may be more "governors" available on our devices these include:
SmartassV2
Interactive
Lagfree
Conservative
Loinheart
Ondemand
Preformance
All of these governor's will make a slight or more noticeable change to the performance of your phone there will be some screenies of my setup below the main post.
The overclocking application I use is called SetCPU thus is available here on xda for free, but is also paid for on both the android market and the amazon market place. If you wish to get it from xda, for now search it because I will add the thread link to this post soon.
As mentioned before if you have issues regarding overclock your phone be sure to post and I and other will be glad to help out, remember no question is stupid.
The kind of information of which will be posted and discussed in this thread is:
Temperatures of devices cores.
Screenies of peoples "profiles"
Selected governors
Questions regarding overclocking
Solutions to problems for users having issues
The five posts after this one are as follows:
CPU profiles, examples and what they do.
Thermal throttling, what it is and also what concerns it.
Governor, recommended ones and more in-depth of what they do.
How to flash New kernels for new users.
Questions and answers (FAQ).
So let's fill this thread with useful information and questions regarding all this overclocking business
But please do not spam this thread with useless information because we do not want this locked, as I could be a resource, also if you guys want this post sticked please say so and I'll see if it can be done.

Overclocking profiles
Okay as mentioned before in the above post I will post some screenies of my current profiles, of which I prefer. However you can use my settings as a reference and create your own, if you do make a screenie of your setup and post it to give others more options, or more understanding of what these are, and what they are about.
A little more indepth about CPU profiles is that let's say if you wanted to conserve more battery during the night for example, you could create a profile saying what clock speeds to run at, at particular times this meaning from 12AM-8AM with a clock speed of 122mhz-386mhz this configuration will save more power than 122mhz-600mhz or 767mhz or even 806mhz in an overclockers case.
For example my clock speeds are:
122mhz-3xxmhz in sleep mode
806mhz-806mhz when charging
122mhz-4xxmhz from 2.00AM to 8.00AM
2xxmhz-806mhz when doing tasks in sleep mode such as titanium backup.
Update: It appears with some configurations, that if music is playing the lag may be present when waking the device.

Potential thermal throttling
Just like any other computer weather it is a desktop, laptop, phone or even a tablet, and no not the ones you eat lol
All have thermal limits, also known as thermal throttling which is the CPUs thermal limit, when this reached the system may become unstable,reboot,or turn off entirely depending on what the device is coded to do in these situations.
I have a theory of why some people's phones can overclock higher than others without issues, or really high core temperatures. I think it is down to the environmental variables which include:
Humidity, the more humid the environment is the harder it is to cool a device, due to a higher density of water being in the air unable to transfer heat effectively.
Heat, this is a big problem for computers what are overclocked, more speed means mote heat! Unlike a gaming computer, where there is a whacking heatsink to cool the CPU efficient enough to prevent overheating
However, for any android phones, tablets it is a different story, the cooling system inside these devices is known as static cooling, meaning there is mire heating being trapped inside the system and isn't being moved my fans etc...
Now I believe if the people having issues with overclocking should post their temperatures of their CPU to see if there is a difference between devices which can overclock far, and the ones that can't.
To get more information on temperatures I think anyone who is overclocked should post their temps both idle, and after playing some games etc...
For example, using the setCPU application widget on my home scene I can read my temps of my CPU on the fly, if you can't provide a screenshot of this for what ever reason then post you information like below:
IDLE: @122mhz-806mhz is around 18-22 degrees.
AFTER WORK (GAMES,APPS ETC...) @122mhz-806mhz is around 32-39 degrees
If people post these figures then we will know if there is much of a temperature difference between devices.
Let's get some boss results and figures to help figure out potential crashes,reboots etc... Some users have experienced.
Remember, that thermal throttling, slows down the CPU, so it doesn't cause damage to it

CPU governors what are they?
In the brief explanation in the first post a Cpu governor basically tells android how to access the hardware, in this case the CPU. Basically each governor has a set amount of variables of how long processes can use a thread on the CPU, or how the system handles simple requests, the governor controlles all of the things android puts through our hardware.
Intact a CPU governor is so low level it is actually inside the android linux kernel, meaning that the kernel compiler needs to code these into the kernel to make them available.
There are many governors available, of which can be used under certain circumstances for example:
Conservative, this governor will try to cut the amount of clock cycles the phone will process data with, hence the name conservative meaning it will save power where possible, but resulting in lower performance.
Preformance, this governor is used to squeeze every little bit of performance out of your system possible, great for gaming but not so great for battery life.
I will list other governor functions later on.
Currently the governor I recommend is based solely on use, I mostly use Lagfree which is both good battery life and gaming performance.
If you guys use any others governors post it with why you think it is the best config for you, including your temps, clock speeds etc...
Remember this thread is about gathering information about the thermal relation between phones what can overclock far, and ones that can't.

Flashing a Boot.img
Recently I have had messages from new users who are confused about installing this rom, Well i'm here to help! So I have written a short guide on how to flash the rom, kernel etc... In short simple steps:
Copy the newest nameless to your sd card
Install the rom as normal
When it says reboot after installation is finished, uncheck that box and go back into recovery
Then on the main recovery screen there will be a reboot into fastboot, click that. Note: have your computer plugged into your phone before this, because it will connect better.
Next on your computer find the nameless rom package open it and find a folder called, "Kernel_boot_img"
My advice is to try the 767mhz kernel first, see if your phone boots if it does try the 806mhz after, if it also boots you have a high over clocked phone
You will need to flash the boot.img as normal (fastboot flash boot boot.img), whatever kernel it is (767, or 806mhz) And don't forget the wipe the cache after installing the new kernel as this could cause problems to fix this use this command, "Fastboot wipe cache" then followed by "fastboot reboot" then your phone should reboot.
TO CLEAR ANY CONFUSION:
Don't flash both kernels at one time, it will not work like that try one at a time to see if it boot with success.
If it doesn't boot with one of the kernels, then try the other one most phone work with the 767mhz kernel, while others work with the 806mhz
If nothing else work message me and I will try to help, however your phone should work and boot with success with these step, be sure to follow them closely.
Good luck, I hope this helps any new comers having problems.

Y U NO Work? FAQ
Y U NO WORK! Is often said by people who are angry your phone isn't working with some kernels, I am going to list some of the most asked questions new users have sent me regarding this subject:
Q: My phone won't boot, instead it is stuck at the green and white "HTC" screen.
A: All I can say my friend is try the other kernels available on the nameless thread there are currently two of which are 768mhz and 806mhz if you have tried both you unfortunately have a phone what doesn't like extra heat.

Reminders about thread, Kernel history, Member temps etc...
If other users require extra help please post a question below, me and other members will be glad to help you out and get you on your way. However, remember that this thread needs to remain clean! No spam posts, and no flaming arguments!
This thread is a home to share the following things,as mentioned above, and try to resolve potential issues regarding overclocking these include:
Phone CPU temputures
What kernels work, which ones don't
The highest temputures you have, compared to other who cannot overclock

Wow its War and Peace!
Awsome work , thankyou. I'll sort out my temps etc later tonight as I have to go out now . and I'll hit you up with some much deserved thanks . For some reason my counter says I've used 8 already and I've not used it yet

Thanks Richard . I'm trying my best to resolve issues other members are having. I'm soon going to make another thread to help out with issues on roms, cache errors etc... So look out for that one.
Hopefully this thread can be stickied, so all new and existing members can see it without creating new threads with the same questions, as it is a waste of space.

okay, here I go: me and my phone live in London, today the weather turned to nice lol.
767 oc kernel - performance/deadline
IDLE: @767mhz-767mhz is around 27-31 degrees.
AFTER GAMING, ANTUTU: @767mhz-767mhz is around 35 degrees
And, strangely since I'm using either V6 SuperCharger (it has a kernel panic tweak) or the performance/deadline combo, the phone did not reboot on 767, previously I had to downclock to 722 to make it stable, because it rebooted under heavy usage like gaming.
I will try different combos and report back if it stayed stable.
But I was wondering if the issue with the 806mhz kernel was due to heat, the phone would still boot up, isn't it?

Re: Overclocking information, governors, profiles, problems, solutions and FAQ
I leave it at 722max 320min it is 30'c 87'f I use smartass2 and sio.
What's good configuration anyone know?
I know old settings that are good are
Ondemand-noop
Ondemand-deadline
Lionheart-sio
Lagfree-sio
Smartass2-sio

Hmm that might not be strictly true, a CPU can get hot after first boot up very quickly just like any Computer, I have some other ideas why some peoples phones don't boot too, i'll post them in my thread and update it.

I use 722mhz max - 320mhz min lagfree-deadline .
None of the 800mhz OC kernel works for me.Doesnt even get to boot animation
Temps:
Idle : 28-30 'C
Charging : 34-35 'C
Charging + Playing a heavy game like shadowgun : 40-41 'C
I really dont think its due to high temperature (but one can never be sure about these things) as even at 41 'C the phone doesnt actually reboot.It only reboots on setting a higher OC like 767mhz

Interesting, nikhil16242 I will try to get shadow gun and use the same clock speed as you and compare my temps to yours, see if there is a difference between them.
I have another idea what it could be, and i think it is related to what frequencies each phone supports maybe einstein.frat could try something slightly under 806mhz and see if it works. But i think it is how to frequencies are counted on the kernel, maybe if einstein.frat can change some of the values, to lower variables it may work I need to look this up any input about how kernels work would be helpful.

have any of you guys tried to flash the 806mhz kernel WITHOUT wiping the cache through fastboot?

Re: Overclocking information, governors, profiles, problems, solutions and FAQ
Yes .
Tried all possible combinations like flashing the rom cleanly and flashing kernel,flashing kernel with and w/o wiping cache .

Did the first overclock kernel work for you, by zeroprobe?

Re: Overclocking information, governors, profiles, problems, solutions and FAQ
Yeah, oc kernel by zerophobe did boot for me, but I think it used "fake" overclocking since benchmark scores where more or less the same as stock kernel .
Sent from my HTC Desire C using xda app-developers app

Well i think figures should be changed inside the kernel, I don't know what maybe some of us can experiment with unstable kernels. It is two things heat, or how the kernel is coded, which ever way we need to find out, hopefully overtime we will.

[APP][MAY 22] Myrt Torture Tester 0.5.6 Beta

Welcome to Myrt Torture Tester.
As always, this app is BETA, expect bugs. Tested on Stock GB/HP Extreme & guestekrnL, CM7/Etana, CM9/HP ICS & Harsh.
Will only work on OC/UV-kernels.
It's primarily intended as a tester to find your stable frequencies and voltages, but can also be used as a battery-life tester and a rough benchmark.
This app comes with no more support than the 2nd post. If you don't know how to use it after reading that you don't need it.
Using this app, you will be capable of causing actual damage to your device. I take no responsibility for any consequences.
This app shall under NO CIRCUMSTANCES be included in any ROM, or uploaded any other place than this post.
Changelog
0.5.6 - Fixes crash when system is unresponsive for long periods.
0.5.5 - Keeps reading the current cpu-frequency throughout the test. (Some beta kernels unexpectedly change frequencies during the test, this allows you to see it.)
0.5.4 - CM7-compatability-fix.
0.5.3 - Fixes frequency not being set on guestekrnL.
0.5.2 - Fixed links on about page.
0.5.1 - Plays nice on non-oc kernels.
0.5.0 - First BETA-release
HOW TO USE:
In its simplest form, the app is a benchmark. You start a CPU-test at a specific frequency for a specific time-period and get the average Mflops-result. If you are going to compare different kernels, it will give you a normalized to 1Ghz result as well. Different kernels usually have different frequency-tables, so test them at the closest steps you can find, then compare the normalized result.
The more useful aspect of it is to test if a specific frequency is stable at a specific voltage. The app only allows to test the frequencies in the voltage table - because if it is stable at those frequencies it will be stable at all other frequencies which fall within those voltage-steps. If you have undervolted too much, the phone will usually reboot pretty quickly. If you have undervolted "on-the-edge", the phone will likely freeze. If you have undervolted so that it is basically stable, but sometimes fails, you'll either get a crash to the desktop or MTT will inform you of a calculation error. If you are testing for stability you need to test for at least 60 minutes to have any confidence in the result, I've had several tests fail after 45-50 minutes.
It can also be used to see what impact, if any, undervolting has on the processors' power-consumption. After you have made sure a frequency/voltage-pair is stable, you can run a battery-test and compare it to an identical test at stock voltage. This will simply run from a full(ish) battery to a certain battery percentage, and give you how long it was able to run. Since the battery-percentage is pretty loosely coupled to the actual battery-charge, it will also give figures for consumption per minute or second. This kind of test should also be run over a long a period as possible to get accurate results. Measuring from 100% to 90% will only give you an indication, prone to error. You can not compare a test between, say 100->50 and 100->20, because the discharge rate varies with the charge-level.
For most accurate testing and benchmarking: enable flightmode, unplug the device, freeze any apps which may run in the background, uninstall everything you don't need, wait 3 minutes after booting before testing, do not touch the screen or move the device while a test is running. Even then there are Android quirks which will cause some variation in the results. Therefore the same test should be repeated as many times as you can afford.
The major enemy of stability, assuming you have enough voltage, is heat. Make sure to test the device under the same conditions as it will be used. If you're going to overclock on a hot summer's day, test it on a hot summer's day. MTT dims the screen to minimize the impact it has on the battery and heat-generation, be aware that your device will be hotter when the screen is at normal brightness.
Stability tests should also be performed at different battery-levels. If your device is stable when the battery is fully charged, it does not automatically mean it will be stable when it is almost discharged.
MTT logs all succesfull tests (max 200 lines.) If you enable "Store log on sdcard" in preferences the log will be saved to /sdcard/MTT_Log.txt.
Known issues:
o Sometimes the device will give you half the score you should get. I do not know if this is a kernel or android-bug, but it seems that both test threads get scheduled to run on the same core, and the second core goes unused, even when it is active. Exiting the app and starting it again does not help usually, but killing it sometimes does. Rebooting is always an option.
o Not a "known issue", but this app lets you under- and overvolt in 5mV steps. Different kernels may handle this differently, either not undervolting at all, or adjusting it to the nearest 25mV step. It has worked on the kernels I have tried, but there are too many kernels out there to be sure.

Really interesting! Big thanks

Doesn't seem to work for me, always goes to my max set freq of 1.1ghz, no matter if i set it higher or lower in the program. Same mflops result too. Changing the max freq in guesteoc results in that new max freq being used all the time in the program.

Ok, thanks for the feedback. Which version of guestekrnL? I'm mainly using that myself, works here on 1.7.
EDIT: Ok, I've found the reason. I had disabled the 00cpufreqenabler script (to simulate other kernels), but it didn't work after I enabled it. Will release a fix as soon as I can override the permission properly.

Giving the new version a try, and not that it matters now but I'm using 1.7.0t2
Yea working fine now
Updated to 0.5.4 - Now the sliders behave properly on CM7.
Myrt, do you think that we have more than one different hardware inside our phones? Because the results are way to different from one ppl to another, for example, Temasek can't OC even to 1.1GHz, and Vadonka puts at 1.4GHz without the burn, with the tests, I get to 70ºC in 2min with 1.1GHz, but the strange thing, is that the phone doesn't lags or anything to show that it haves an high-temp. Did you have some screen of the test in your own phone? I have exchanged my first phone because it always get too hot for me, my second gets hot always when I try to play any game.

No, we have pretty much the same hardware, specification-wise. It is very common to have different tolerances for speeds and voltages. I'm pretty sure that the moment Vadonka tries my app at 1.4Ghz, he too will get a hot CPU.

I didn't take a screenshot, if that is what you ask, I have the app abort the test at 72C, and the temp falls quickly back to normal. I don't even have vadonkas kernel installed anymore, I'm a stock man, installed CM7 just to make the app compatible.
However, I guess we can encourage people to post their temps and frequencies here, in this thread. If anyone manages to run 1.4Ghz for more than 5 minutes and not reach 70C I'll be impressed. (I do all my temp-testing when plugged in though, probably easier when unplugged.)

I had these temps in Spica HP kernel, so stock rom, CM7 with Vadonka, I saw an 84ºC (leave my brother playing in the phone, and he said to me that the phone was hot haha)

If we can't run 1.4GHz for me than 5min without reaching 70ºC, and 70ºC is the maximum temp, we can't play or let the phone in the frequency for daily use?

Well, no, I'm not saying that, there are too many unknowns.
1) We don't know if the reported temp is correct.
2) We dont' really know the max temp for tegra2. (The 70C figure is not from an official source.)
3) This app is meant to test stability, so temps will get as hot as possible. A game will most likely not stress the CPUs quite as much.
But, all that taken into consideration, 1.4Ghz is probably too high for sustained operation. It will probably be fine for normal use, where the CPUs get to rest once in a while, but not for prolonged CPU-heavy tasks (which this app demonstrates.) That being said, this app is designed to produce as much heat as possible to test stability.
It took me 41sec till the CPU reached 70°C from 40°C on 1408MHz using latest beta 3.0.y etana.

Thanks for this, this app looks great!
I usually don't UV as it introduces some instability to my device even at low -UV values which isn't worth the rather small gain in battery life - but it's still good to know that this app existis if I'll change my mind someday

Yeah, I don't usually undervolt either, I carry spare batteries, and the fear of unstability was always lurking when I did. (I did make an undervolt app afterall, had to test it.)
So with this app my hope is that many myths will be dispelled - using this people should be able to find out what they need.
(A few weeks ago I had forgotten the batteries in a bag in a hotellroom, far away. I really, really, really needed 20 extra minutes of battery-life then. So now I will probably undervolt to voltages I know are safe, just in case something similar should happen. Sometimes 5 minutes make all the difference in the world.)
I cannot set any other V (no UV or OV) using Temasek 99 with latest Vadonka Beta 11.05. Kernel. The program always crash after the 2sec warmup.

Ok, I need some more info I think. First of all, is the app the latest version? If yes, do you get a superuser message the first time you start the app after a reboot? Which values do the bottom sliders show right after starting the app for the first time?
Tried it myself today on temasek 100 with both 3.0.31 OC and the latest beta (OC-only of course), worked on both for me. One installation however failed, and I had to repair the system-partition before the app would work again. (Superuser pretended to give access, but /system wasn't really writable, so it failed.) Check which apps are listed in superuser, if you see the same app listed a lot of times, that's your problem.

Sooorry I'm too stupid, tried the 216 Mhz only which is too slow for the total phone use and test. Program works fine!
Again sorry and thanks for the tool

Ok, good to know, thanks. I will have to look into it anyway, it shouldn't crash even at 216Mhz, but I'll take that as low-priority, in other words tomorrow ;-)

[Q] Kernel for CM7.2 Stable that allows OC and governor change

I have just updated to Cyanogenmod 7.2 stable on my P990 Optimus 2x (Fido Canadian version).
When I go to the CPU settings I cannot change the min/max frequencies or select a CPU governor.
I have done some research and found kernels like Vork and FauxDS, but they are for 7.1 nightlies so I am not sure if it is a good idea to flash them.
What I am most afraid about is the possibility of getting the black screen of death while my phone sleeps (it happened once already but it stopped after I changed to a different charger and reflashed CM7.2).
The reason why I want to change the settings is that there tends to be scrolling lag (my old HTC Desire Z was faster!) and there is also a bit of lag waking up the phone (lockscreen does not appear instantly when pressing power button).
Does anyone know what is the best kernel I can flash to enable frequency/governor changes in CM7.2 stable? I would prefer not to change the ROM if possible as I am kinda nooby in comparison to the XDA community in general. Thanks for any help.
I suggest you try Etana kernel. It has the things you need. Also use CPU master to set profiles and minimum CPU frequencies. I used something like min freq 352 MHz when asleep (don't worry doesn't drain battery) and I had no lag whatsoever.

Are you referring to http://forum.xda-developers.com/showthread.php?t=1427646 ?
If so, do I just flash the zip off the sd card using ClockworkMod? And what are the differences between lite and DS?
Thanks.
All right, after reading, I determined I don't need LOC/HOC/DS as I don't intend to raise the max frequency, I just want to raise min frequency.
Installed the Etana kernel via CWM and it works. I can raise minimum frequency, though I still cannot see a governor option! Any idea how to get my governor setting back?
You can use CPU master and set some profiles. It's not exactly the same as governors but it's as close as it gets and it gets the job done pretty well. As far as I remember there were two governors for O2X - powersave and performance. I've always used performance and I can't tell if there's a HUGE difference in battery usage. I guess performance utilizes higher CPU frequencies when the device is asleep and somehow scales faster to even higher frequencies when needed to. But this might be complete crap as I am not too much into how CPUs work...
And please use the THANKS button (right below the user name), it kind of forum etiquette and it keeps people motivated to help others. Thank the Etana developer too.

Thanks for letting me know, I didn't realize there was a thanks button at first haha.
Fixed!
As for now CPU Master in his profiles let's you choose governor. We have only 2. Power save nd Performance.

Help for OC and UV!!!

hey i needed some help on overclocking and changing some voltages on my device!!
1.i have read threads and guides on other forums before which explain how to OC and what are governers and schedulers etc.
2. most threads on this topic are from different devices' forums
so i thought their frequencies voltages must vary as they have different CPUs and hence started a new thread!!
3. What i want to know is, what voltages should i choose at different frequencies??
or it is completely not important to set voltages??
4. Earlier i used setCPU but it doesnt stick to frequencies i set and resets default 1024 after reboot.
how do i avoid this??
Currently i am using AnTuTu CPU master PRO for doing all this
please guide me if possible provide specific values on which htc incS performs good!!!
my system details are in my signature
any help is appreciated!!

I've commented on this 100 times before but I can't search on mobile. So there are a few threads out there explaining this in this forum. If you can search and find them they'll go into a little more detail than I'm about to.
OK so the OC controller you're using I'm unfamiliar with however they all do the same thing. What you should do is find out which governers your kernel supports and than use Google to figure out what their perimeters are. Generally speaking you're going to want to have different profiles set up for "screen on"and "screen off" for your basic set up. Later once you understand why you're doing you can set the governers for gaming, charging etc.
Set your screen off for around 200 min and 400 max. This will keep your phone from running high frequencies that will drain your battery while you are not using your phone. Set the governer to smart ass or on demand, read about them and see what's best for you.
Screen on set to max 1200 - 1400 if you want high performance and the low to whatever you like just not above 400 as it will not allow your CPU to idle. Set governer to smartass. You don't really need to be running above 1100 for most I stances however you will notice it is a bit peppier. While running at higher freqs you will notice your phone heating up... I have never heard of an incs over heating and frying in every case your phone will shut itself off or freeze. If you're afraid of overheating there's a profile for that too to change your freqs at certain temps.
Do NOT choose "set at boot" until you are certain that your set freqs will not hang your phone, doing this will cause your phone to freeze as soon as your ROM boots up causing a boot loop and you will have to revert to a backup to fix the situation.
As for uv'ing the premise of this is to save battery life, running at lower freqs than intended. I recommend not bothering but if you do want to try and save battery I generally suggest -10 for all values. Be aware it is very common for this to hang your phone. You have to tinker with it to get it right for your ROM.
Hope this helps any other questions just ask.

Thanks for understanding and for helping to keep XDA neat and tidy!
Thanks
Very nice kernel, fast and smooth - great work and port.
Anyone knows if it's possible to use any third party kernel app to boost the headset volume?
Working
Hi this is my first post, infact I joined so I could report my findings.
I would just like to confirm so far that V5 working on my Z3C using the .93 firmware. I didn't need to wipe cache/dalvik/data partitions either.
For purposes of settings configuration, I'll be using TricksterMod
For stress testing purposes I'll be using Stability Test 2.7
Overclocking
Overclocking seems to work, I'll stress test and report back with the results.
I was wrong, it is unstable when overclocking and stress testing, with the phone force rebooting 1-5 seconds in to the stability test which loaded all 4 cores. Tried 2899Mhz and 2880Mhz (were both unstable and didn't try 2.72, 2.75, 2.57 either - I might try stability testing them.) Was completely stable at 2.47GHz, and it actually stuck there, no throttling in place! I stopped the stress test when the CPU temp was around 77-80C as my hand was getting burnt! The battery temp reached about 46C. It took 10 mins of stress testing for this to be reached. When the stock kernel was in place it would begin throttling after about 1-20 seconds under full load. First 2.2GHz, then 2 then 1.7 then 1.5 and eventually 1.25 after about 2-4mins.
I couldn't do a single core test though. I suspect as most games use single core or dual cores it wouldn't get overly hot.
My opinion is that fast clocked phones should be marketed with 2 speeds. The highest it'll reach under a boost mode (turbo for Intel's i5 and i7 series), and a slower speed that it'll average out at under thermal pressure. The Z3Cs would be turbo: 2.5GHz and normal: 1.5GHz.
Governors
These are quick tests I'm performing here to provide a quick look at responsiveness and potential unnecessary CPU jump ups.
Wheatley - most of the time it's hovering at top speed when approx CPU usage is 9%, it'll occasionally hunt down to 300Mhz but then right back up to 2899MHz. This one is speedy though. Governor tunables available.
Lagfree - idles at 300MHz - 960MHz then hunts up to 2.2-2.9Ghz when needed and turns on the second core. It seems to slow back down to idle. This one seems to have fast scrolling, sliding notifications pane quickly). No governor tunables.
SmartassV2 - idles at 300Mhz, speeds up to 422-960 on core 0, and turns on core 1 at 1.2-1.5GHz for a few seconds under fast scrolling and notification pane opening. Seems quite responsive. Probably good for battery life hopefully with the responsiveness of Interactive. No governor tunables.
Lionheart - Idles at 960 MHz for a few seconds then slows down to 300MHz with the odd increase to 729MHz. Core 0 and Core 1 reaches 1.26GHz under scrolling, notification pane opening. As fast as the others. Governor tunables available.
Hotplugging
Intelliplug appears to work better than MP-Decision - now only one core is on during idle, instead of 2.
MP-Decision was disabled to avoid conflicts.
Undervolting
I've only undervolted 300MHz to 675MHz from 775MHz as of writing this post.
Tried quickly undervolting in trickstermod by setting them all about -75mV, stability tested it, appears stable. I'll tweak the voltages a bit better when I do a scaling stability test.
Issues I've experienced
Sound Control is the only thing so far that causes a reboot. However music still plays over the speakers and headphones. Equaliser works too.
Upon rebooting, the CPU top speed will set itself to 2.2GHz, despite being set higher and saved at a higher speed in Trickstermod. Certainly trivial though.
Strange thing I've noticed: On the undervolt part I've noticed that there is a freq called 3033MHz, but no 2899MHz freq. Just an observation.
Misc
Force Fast Charge confirmed working! Before flashing new kernel charge went up 5% in about half an hour. It's now up another 5% in a matter of 5-10mins. This is when plugged to my PC.
Vibrator strength - set to 20 from 31, much quieter on table and can still feel it.
I'd like to say a huge thank you to DooMLoRD and AndroPlus for developing this stable kernel. Now my Z3C is worth the £28 a month I'm paying for again. Since this silly lad decided to bork the camera, Bravia functionality etc by rooting it on the first day. I'll report back and edit the post with my findings.
Max won't go beyond 2.266 GHz, Min won't change.
Hi All,
Firstly, great job with the kernel. Our Z3C is such a capable piece of kit and this just makes it that much better.
I'm running stock, 23.0.A.2.93, unlocked, rooted.
Problem:
I've tried using both SetCPU and No-Frills and while both show frequencies that are supposedly selectable above 2.266 GHz, neither app would actually respond. Meaning the max frequency will still only be 2.266 GHz even if I tried selecting something like 2.458 GHz (which should be selectable given that stock is 2.458 GHz.) See caps.
In addition, the Min value just won't change at all from 300 MHz. The frequencies scale up and down as the load changes but I can't raise the Min (again using both SetCPU and No-Frills) from 300 MHz.
Tried: I've tried turning off stamina mode and frozen apps that could control CPU activity (e.g. I use DS Battery Saver). I changed up Governors and Schedulers. I've tried re-flashing the kernel and it still doesn't change these behaviors.
Question/Need help: Just wanted to ask if anybody else have any problems setting the max frequency beyond 2.266 GHz and/or changing the minimum frequency from 300 MHz? Would appreciate any help resolving this behavior.
Thanks in advance!

Try installing TricksterMod (from Google Play store, trust me, you'll love it!) Then go to General and set the max speed to 2.46GHz or higher, and try using the Ondemand Governor too. I noticed that it wouldn't stick properly sometimes when using Interactive governor. If it doesn't stick for you then turn Frequency Lock on. Then check in the info tab that it's hitting the higher speed. Personally I'd recommend leaving the min speed on 300MHz. If you need constant high speeds, select the performance governor.

Thanks! That did the trick!
Odd that my usual app for the job across 4 other phones - SetCPU - doesn't work on what should essentially be the same job. [emoji55]
Please make sound_control drivers work so its possible to boost headphone volume on the Xperia Z3 Compact... Thanks
Nice work, a lot of updates I like it!
Is it possible to add a change log?
Thanks!
kernel for d5803 with the .93 but not .105
i search a kernel for the d5803 with the last .93 french version of phone
.5.77
Works great! Thanks a lot
Link for Z3C_D5803_AndroPlusKernel_v10.zip is dead
Pls upload in another location.
Yay sound control is working, thank you so much you're the best!
How to make this?
Hi AndroPlus,
I'm trying to figure out how one would go about building this boot.img that you've created.
What platform and compiler are you using?
Where are you getting sources the for the kernel? This file?
c9af6fc647060fb85dd646798453ec8f 23.0.A.2.105.tar.bz2
How do you construct boot.img from zImage + recovery?
Sorry if these are dumb questions.
Edit: never mind, I figured this out.
http://developer.sonymobile.com/kno...evices/how-to-build-and-flash-a-linux-kernel/ contains most of the information I needed.
The arm version of gcc that ships with Ubuntu 14.04 worked fine - arm-none-eabi-gcc (4.8.2-14ubuntu1+6) - no need to track down any mystery binaries. I did have to make several modifications to the kernel source to get it to build. Interestingly, some of the cpufreq stuff contained code that was incorrect. Someone at Samsung needs to go look up what "sequence point" means.
The hardest part was figuring out how to turn the zImage + ramdisk into something I could boot.
This: https://github.com/sonyxperiadev/mkqcdtbootimg was the correct tool to use - again, no need to track down any mystery mkbootimg or dtbTool binaries.
Hope this is helpful to someone. As someone new to Xperia dev, I found most of the information out there worse than useless.

Overclock CM11

Hi there,
really sorry if this has already been around, but i've been searching this forum up and down and didn't find a thing.
Anyways, i was wondering how i could enable overclocking under cm11 nightly? Could anyone point me towards a solution? Thanks
Well ...
http://forum.xda-developers.com/droid-4/development/5-0-custom-oc-kernel-t3041512
It should work (in the past it works)
Install it on your Cyanogenmod Rom

There's a guy who said that that kernel doesnt work on cm11...it work's for you in the past?
For CM11 and other AOSP 4.4 ROMS, the most fully-featured and overclockable kernel is JBX. You can use the one intended for the RAZR.
Joojoobee's is good, and certainly the best for Lollipop, but due to its extra voltage management stuff the JBX kernel has a higher overclock ceiling.
Use the newest kernel from here.
Boot into Safestrap, make a backup in case something goes horribly wrong, then flash the package to start up the installer. In the installer, don't install any of the tweaks, at least a couple of them cause instability for our phone, and don't bother with the init.d stuff. Just install the kernel itself and Trickster Mod. Trickster, FYI, is probably the best app for managing JBX, but other apps can as well.
Done. Reboot phone, hopefully it won't bootloop, once back up increase speed until it starts freezing when you try to use it, bump voltage 10-20mv, find ceiling again. I think the JBX thread has better/more detailed instructions, but that's about the gist of it.
Maximum advised voltage is 1490mv iirc, don't try to even approach that unless you want to cook eggs on the back of your phone.
Thanks a bunch!
After messing around with both solutions, Jojobee's solution gave me a bootloop but the other one worked.
However i can't seem to get past 1300mhz when overclocking, that seems to be the limit. I was aiming to try to reach 1400, any idea how i could go about that? I can't seem to find an option to set the max frequency higher than 1300.
Well i was playing a little with JBX kernel..these are my conclusions:
- Kernel install/works fine if you don't install 10% battery mode..otherwise you are goingo to have android crashes
- Kernel performance it's below than current cm11 m13 stock kernel...i believe is due to full scale freq that it has...cpu spend a lot time switching from one freq to another...if you overclocked you will have almost the same performance than NON-OC stock kernel..that's why stargo applied and later reverted full scale on stock months ago...meaby if JBX kernell would have support to boost driver (like cm12 OC kernel) it would be better...but it hasnt...
So my conclusions...dont waste time on JBX kernel...sorry my 4 my english

I don't think you can set the CPU higher than 1.3ghz, at least not in the way you're thinking.
In the case of the JBX kernel, you overclock the Main Processor Unit (MPU) speed. I don't remember what tab it's under in Trickster, but it should be the same one as the voltage settings. I couldn't even begin to guess where it'd be as far as other apps.
The default is 100mhz. This is multiplied by each frequency step; e.g. 1.3ghz is actually a 13x multiplier of the base 100mhz.
So to obtain 1.4ghz(ish), simply increase the MPU clock from 100mhz to 108mhz, since 108*13=1404.
If you're lucky, you'll be be able to do this without needing to touch the voltage, if not...read the FAQ in the JBX post, because I don't remember offhand exactly how to set voltages :v
Once you know how, I would think a 5-10mv bump would be all that'd be needed to stabilize most CPUs for 1.4ghz.
fyi, ignore if you already have stuff for these:
Antutu is a decent app for both testing stability and checking to make sure you're not hitting the heat throttle.
Cooltool isn't a bad thing to use either, if configured to show CPU speeds, since it'll show you if the CPU has been forcefully throttled back (if the CPU gets too hot, it'll forcefully change the maximum multiplier to 10x/11x to protect itself from baking; if it does, back your voltage off and be happy with whatever speed you've attained).
