I found a link explaining how to overclock motorola milestone phone on the fly without any reeboot or flashing a custom overclocked kernel. This information might be useful for overclocking galaxy 3 mobiles and I think this would be a better way of overcloking, since it doesnot require flashing a separate overcloked kernel.

Since our phone is using s5p6442 cpu,there are some slight changes that has to be done. I tried and compared the guide with our froyo kernel source released by samsung.
I found the frequency table for our cpu to be present in
arch/arm/plat-s5p64xx/s5p6442-dvfs.c
But i couldnt find which function manipulates the frequency tables present here,I'm not a developer so I'm posting what i know here, Hoping some developer takes this information and implementes it.
downloading the source codes now....wonder if i can figure out anything~im just a noob

Hello, I have an LG Optimus pad running honeycomb 3.0.1. There is very limited development for the optimus/g-slate right now, but there are a couple of custom kernels available. Unfortunately, the kernel I am interested in trying out is OC'ed to 1.5ghz by default and my tablet becomes unstable at anything beyond 1.2 so I can't get it to boot. I assume that the source code could be modified somehow to lower the default clock speed, but I'm not a dev and I have very little linux experience so I have no idea how to go about changing it. I have read a couple of guides regarding recompiling a kernel from source and I think I could handle the recompile if someone could just point me to the files/values I would need to modify. Any help would be greatly appreciated!
Hi community:
I wanted to know if there's some way to edit frequency values on the stock kernel and hopefully to add new governors. I tried some custom kernels but right now I want to stick to the stock kernel because I read that it has a proprietary driver that manages CPU (MPdecision I think it is).
I would be willing to compile, test and stuff on my device but if someone knows an easier trick (build prop or stuff) I'll gladly appreciate it.
Also if there's a stock-based customized kernel out there with such capabilities (I searched but all are AOSP based) I would try it.

i don't know if it works but try using engineering mode..
This app was mentioned on XDA news today - claims to let you tweak CPU: (no mention of it requiring a custom kernel)

Hello everyone, this is my first topic on XDA after lurking for a while!
Anyways, today my topic is going to be concerning an Android Mini Tablet called the PlayMG. It's a WiFi tablet by a startup that's now gone bankrupt. The actual name of the device (development-wise) was the ACTScom A930. It was supposed to be a small 4 inch tablet like an iPod Touch with Android. You can find various info by googleing the name.
The specs go as stated:
ARM TCC8920 @ 960 MHz
1 GB RAM
4 GB DDR3 Storage
Android 4.0.4 ICS
Geekbench test:
http : //browser.primatelabs . com/geekbench3/356000
(sorry, I'm new so I can't post links until 10 posts)
The device was pretty cheap (around 90 dollars) and since then I've rooted it. I had to use SafeRoot because there is virtually no support anywhere for this device. As you can tell from the specs above, the device is fairly weak. My goal is to overclock the device to run at around 1.10-1.25 Ghz, however I'm stuck on the stock ROM and kernel. And as you can probably guess, there is no one to develop and overclockable Kernel for it. I have a few questions that I would like answered:
I was wondering are there any methods to overclock the stock kernel? Is that pretty much impossible?
Are there any ICS (or any) kernels that might work on this device?
Could I build the Kernel myself?
^Questions regarding this:
-Since the company went bankrupt, I can't really obtain a stock kernel, Could I somehow extract it from the device itself?
-If I were able to get the kernel, where can I go on XDA to guide me to building an overclockable kernel?
Does anyone have any ideas on how to overclock this device? I'm accepting all ideas, good or bad!
Thank you everyone in advance. All responses/knowledge is welcome!
Im also looking forward to this... Have a samsung galaxy star pro... Have compiled stock kernel from source successfully... It works... Nw i need to add oc nd everythung... How shuld i do it??? It is a spreadtrum device...
Anyone?

Hello! I have the Boost Mobile LG Volt and I am somewhat of a noob but smart enough to get it rooted on V4 using a rollback guide and towelroot. My problem is i hate the stock kernel and hate not having voltage control. Is there a flashable package that i can use to add voltage control and all of the other fun things that come with a custom kernel? Ive seen guides on porting roms to my device and they seem fairly simple since its just editing a zip with all custom stuff and leaving the sys files alone. Again the kernel!!! Ive tried flashing so many diffrent kernels but they all softbrick my phone
I love this phone. With root i have CPU settings so it lasts 3 days heavy use. I want more !!! Please help!!!
The stock kernel for this phone is available on githubhttps://github.com/chevanlol360/Kernel_LGE_X5
And from what im reading kernels must be device tailored?

yes sir they do. development is still in its infancy, there are people working on cyanogenmod right now, but they "JUST" got audio support, so you may want to wait a minute. There are a few custom roms available, just takes a lil google-fu.
Also you are very lucky to still have a working phone, careful with those kernels.
Hi everybody.
I have testing some LineageOS based ROMs lately in my P5110 and P3110 and found no overclock option so far ?
Considering the low hardware profile in our tabs and the actual real overlclock, better user experience and battery tunning / real gain we get with some CyanogenMods 6.0.1, I see no point using, until now, the new LineageOS based ROMs!?
So I ask: Is there any known LineageOS ROM or compatible kernel with overclock potential that allows to improve the user experience as the "old" CM 6.0.1 does ?
Thanks

No luck here as well mate, I've been forced to stick with CM13 since OC and themes are a must for me
Best user experience, for me, is with CM 6.0.1 from "[ROM][P31xx][P51xx][MM][6.0.1][Linaro][SaberMod] CyanogenMod 13" (https://forum.xda-developers.com/showthread.php?t=2686613) and "[ KERNEL - AOSP] Dhollmen Espresso" from (https://forum.xda-developers.com/showthread.php?t=2176563&page=138).
Can run everything I need with good speed and make tweaks to allow battery savings even possible!
Hello everybody.
I have read previous answers, thanks.
Considering the time since the original question, I would ask again:
1- if there is no option so far to add an overclocked kernel to our tabs ?
2- I am not a developer, but maybe I could get the info needed to build my own overclocked kernel and share it with the forum, where to start from ? I think these would really be faster for those already with the proper skills to do it! I mean: do you developers really use your tabs without overclock nowadays ?
Thanks again.

1-There is still no overclock available.
2-I am not a developer (yet) but I think the tab is fast enough as it is (running Slim7 if you want to know) and I don't think overclock is necessary. The place to start for building a kernel is google. I think I saw a guide in the past.
Also, keep in mind that devs make things because they want to and get no reward for that. So don't ask or press them to make anything. If you create your own kernel it will be greatly appreciated, but I think you wouldn't like people constantly asking you for something (and yes, overclock has been asked for a lot of times in the past).
