[Q] Manually set clock speed?

I've used SetCPU in the past and have determined that my max stable clock speed is 113600; I've also read that using SetCPU to control clock speed can create some problems.
How would one go about manually overclocking the phone without using SetCPU? I was looking around in /sys/devices/system/cpu/cpu0/cpufreq and it looks like there are kernel settings there, just want to make sure I don't bork anything in the process
Thanks in advance!

From my understanding is that if you get an overclock kernel it will basically run in the same fashion as your current kernel (as far as governing speed goes) except you'll have a higher max frequency.

SetCPU is the GUI to do what you are talking about... Are you looking to go past 1.113? I can only get to 1.113, but if I run Hyrda's OCOV kernel I can get to 1.15.
I would say if you don't know what you are doing, I wouldn't mess with it. Nandroid is handy if you do.

I'm running invisiblek's #16 kernel but max clock speed is showing 998. Not trying to go over 1.13 but thought I read somewhere about being able to manually change it in the system files somewhere without using SetCPU.
IIRC the idea was to use SetCPU to determine your max stable clock speed, then change it manually in a system file somewhere and then not use SetCPU.

Try uninstalling/reinstalling setCPU. I've had issues every once in a while when flashing a new ROM, then doing the app only restore from a TI backup cause issues.

Personally I can't say I've ever had any problems using SetCPU, but if there's a way to make it default to 1.13 without having another process running then I am all for it, thus my question. Just don't know where to change it

I can tell you i am 99.9% sure that you were right with the file location in your first post.
If you check chads thread SOMEWHERE in there i think its mentioned... Sorry to say but i have no idea where.

Here's a script that Ziggy wrote, you can edit it to your needs and flash it and fix permissions. Without editing it's set at 1.113GHz Interactive screen on and .384GHz Ondemand screen off if I remember correctly. It also has another tweak (memory management I believe?). But hey, it's a start.

Much appreciated guys, I will check out Chad's thread again and look at that script. I just don't see the need for SetCPU if I can just plug in my known stable values and roll it like that Thanks again!

Fixed lol sorry

LOL Blah! :-D

I have tried editing those files and it does not seem to change the clock speed. Anyone who has successfully done it manually could you please list all the specific files. Also im going to examine the script that was linked and see if i can tweak it a bit. Ill post any findings here.

I use the custom kernel #18 and setcpu, clocked to 1.115 easily with cm6.1. works awesome and smokin fast.

I edited Ziggy's script using EditPad lite (free, just Google it) since I'm on Windows so as not to change the format. Flashed from recovery then fixed permission in Root Explorer. Worked like a charm.

[q] want a rom with overclock built in...

Can anyone tell me the best rom that comes with an overclocked kernal built in? Looking for a kernal that has killer battery life also. I've been looking but i'm new to the dinc and am not sure what the best one is. I tried to install a custom ziggy kernal with incredibly re-engineered installed but it started rebooting every time it started up... Any help is appreciated. Thanks.

Did you read everything before flashing ziggy's kernel? this is quoted from his site. did you have setcpu installed before you flashed?
NOTE1: If you’re having problems, please uninstall/disable SetCPU and any init scripts first. A lot of the issues are OC related. If everything works fine after doing that, slowly start over-clocking, if not, please post. Once the problem speed is found, report it, but most likely, it’s a voltage issue, not all phones/processors are equal. Since these kernels have snq-’s VDD sysfs interface, you can modify the VDD levels yourself. If there are any Java developers that would like to tackle the task of writing a program to assist, please do, I’ll help as much as I can

oh and make sure you dl the right kernel its the bottom 2 on his page. i made that mistake earlier today. tryed loading a bravo kernel and my phone got stuck in the splash screen

Incredibly re-engineered comes with Lou's #8 kernel, which is my understanding that it already has pre-configured screen off speeds, governor etc. It could be as simple as a wipe cache/dalvik that would solve your problem.
Other than that, i'm curious as to why you are looking into OC when you want killer battery? Those don't go together

Ok. I missed the setcpu statement. Ill try that... and I want to oc because this inc wont play the only game I play worth a crap compared to my old x... homerun battle 3d... im hoping that will help...

hmmm homerun battle 3d plays fine on my end. Check my sig for my rom and kernel, stock speeds.

chads incredikernel is probably the best for gaming, its oc-able..i actually run it some days on 1075 mhz performance, and get great batt life

[Q] Help with overclocking.

newbie member here needing help with overclocking my evo. i am very familiar with loading custom roms but for some reason i can not find any step by step guides to overclocking. i am running the fresh evo rom with king kernel 9. i downloaded the supersonic zip and tried installing it from recovery, and my phone wouldnt reboot past the first "htc evo4g" screen. just kept rebooting into that screen. any help would be appreciated. and if i posted this in the wrong place there is no need for assholes telling me. im new here.

What was in the supersonic zip? What exactly were you trying to flash?
The easiest way would be to get setcpu, and then adjst the values.

Just get setcpu from the market. Overclock away.

As teh roxx asked, what was the 'supersonic zip' that you flashed? I am not familiar with it. Is it something specific to fresh's rom? From the point you're at now, your best bet will be to restore a nandroid backup (if you have one) to get you back to where you were before you flashed the 'supersonic.zip'. If you don't have a nandroid backup to restore, you're most likely going to have to re flash your rom, if you are indeed completely stuck at the splash screen. Have you tried wiping cache and dalvik cache, then rebooting agaain? If it just hangs at the splash, restore nandroid or reflash the rom. Thats basically the only option to ge t you up again.
And I don't really overclock at all, but I believe you just need a kernel that supports overclocking, and use an app like SetCpu or OS monitor to change the clock speed. Never check the setting 'set on boot' until you're sure that the changes you've made are running stable.

Just flash cm7 it has cpu governor built in

Why do you want to overclock your device?
In all likelihood, you should expect only an improvement in CPU frequency of about 12%.
However, you should consider what the potential consequences of that could be. Although there are certain tolerances included, you should consider that consistently operating at higher frequencies could negatively affect the durability and/or longevity of your device's CPU. If additional cooling were something that you could add, then perhaps thermal thresholds would not be an issue. Because smearing thermal paste everywhere is not an option, you should consider another option.
The advantage of a custom ROM is that in some cases it's designed with profiled-governors and absent bloatware that tends to prematurely drain your battery and decrease overall performance.
I am not convinced an increase from 984 MHz to 1113 MHz is worth being tethered to an AC outlet.

+1 on this. I've played with numerous ways, always seem to go back with just the Rom and the kernel.

[Q] DINC2 CM7 Kernel? Noob question.. (solved)

Hello, I have an incredible 2 rooted with cm7 on it, and it works well but I would like to Overclock it. I have setcpu installed, but when I try to increase the Max speed or set the profile to performance or anything it force closes, so I am assuming I need a kernel that can be O
Overclocked.
This is the first time I have ever looked into getting a new kernel and it seems easy enough, I'm just having a difficult time finding the kind of kernel that I need.
Any help or information is greatly appreciated, and so is your patience.
I used the revolutionary program to gain s-off amd then root my phone, if that makes a difference.
Thanks everyone!

If you have cm7 installed, then you can already overclock without setcpu. There is a built in oc feature with cm7 in the settings. Menu-settings-cyanogen settings-performance- at the top will be the cpu settings for overclock.

Thanks so much for the reply, I actually found this last night when I was laying in bed playing with my phone. Everything is working just as it should now.
Thank you!

As far as kernels go, there are a few to choose from since you're running an aosp based rom. They offer slightly different advantages in overclocking by giving you an extra governor and different voltages. This is not something you necessarily have to flash, but its an option you have.

[Q] Set cpu for root users

I just rooted my s3 and would like to overclock it a little. Just wondering what the best settings would be and if Set cpu is indeed the best app for this. Thanks in advance and I apologize in advance if I'm in the wrong section.

First you're going to need to flash a kernel that has overclocking capabilities. I highly recommend ktoonsez however if you are not familiar with extreme customization, then faux or lean kernel are better suggestions
Sent from my SGH-T999 using Tapatalk 2

I also suggest that whatever app you do use (I use SetCPU as well but they all generally work the same), DO NOT SET ON BOOT.
Since you aren't quite sure you know what you are doing yet, if you input a wrong value or your CPU can't handle "that high" an overclock or your CPU cannot handle "that low" of an undervolt and have it Set On Boot, you will be stuck and have to Nandroid back.
Once you know if certain values work for you, then use Set On Boot.
