I have a question: why I can't overclock my SGS past 1.2 ghz. When I try to set for example 1.3 or 1.4 it freezes and I take out the battery in order to make it work again. Is there something I do wrong, is it a general problem with more SGSs? If somebody can , I really appreciate. Thanks
it is a kernel thing.
the kernel has to support those frequencies.

I tried with tegrak overclocking with voodoo kernel (the application itself doesn't need a kernal that supports those frequencies) and with Supe Optimized Kernel (1.4 ghz) and voltage control and setcpu and is the same result:freezing.
Not every cpu is capable of stable overclocking past a certain threshold. You have probably hit the max speed your cpu can maintain.
I agree with you but then why there are other people with the same phone as me that can overclock them at 1.4 ghz?
With CM7 or miui and either bilboa or zacharius kernel you can overclock to 1300 but I haven't found a kernel that allows 1400 either, I think those that are doing it are hacking the CPU settings themselves.
My phone gets really hot at 1300 running apps like dungeon defender so 1400 might just be a bit too much

I am using Darky's 9.3 ROM but my problem is that i can't even touch 1300 mhz because my phone freezes.
Maybe a dumb question, but, do you overvolt as well as overclock? Maybe the cpu isnt getting enough juice?

+1... not sure if there is much benefit at all to undervolting.. it just seems to make it immediately less stable...
can someone shed some light?
I've seen someone test this on another forum somewhere, and the difference the undervolting makes to the battery length is negligible..

The principles of ovetclocking a PC also aplly to phones. Undervolting reduces the power available to the CPU. Undervolt a little and you'll save a little power. Undervolt.too much and the CPU won't get enough power to do basic functions hence freezing.
Every CPU has a limit to which you can over clock. You can overvolt to a point but then then the CPU reaches its limit.
From what I understand (read in another post) the hummingbird processors are not suited to overclocking. Where the arm such as that in the Motorola milestone clock really well. (You can oc a 600mhz milestone to 1ghz before you start seeing instability)
Hope this helped.

I understand the intention of undervolting as i am pretty good with PCs. Got my good old i7 overclocked constantly. But undervolting on the SGS has yet to show me any definitive advantages.

Hey guys ... I found a link on the setcpu xda page that explains the different governers ... Now im wondering which one to use -_-
By far interactive and smartass(nice name) look like the best choice ... Im running at 1.4 ghz max on mdj's v2 (nice work bro) cuz 1.7 is little too much even if i can do it
So which do i pick for 1.4 ghz? Smartass or interactive? Im using smartass right now ... Guys have any ideas? Which should i use? Some help would be nice ^_^
Thanks in advance ^_^
This is the link i spoke of btw ... forum.xda-developers.com/showthread.php?t=843406

I prefer OnDemand with MDJ's Kernel, I find it more stable than the other governors available, with smartass I found the phone locking up and needing battery pulling and I'm running at 1.4ghz too, but that might just be my device and ROM.
Hmmm ... Smartass is quite responsive but its pulling my battery .... I have lockups with smartass if i go higher than 1.4 ghz ...
Im gonna use ondemand ...

I know this phone is new and its going to take a little while for development of this phone to get going but I have a question.
Im using krabapple's kernel at the moment. I like to get the most out of my hardware and I am wondering if an overclocked Kernel is or will be worked on?
Id like to be able to not only Overclock the CPU but also the GPU. I know Krab is planning a oc kernel so that's great news. An OC past 1.7Ghz and up to 2Ghz would be fantastic.
Cheers!
Over clock up to 1.8 GHz was discovered and worked. However the performance gains were so insignificant it was given up on.

Thanks krabapple - looking forward to some tasty custom kernel for the T, currently using the advance stock one but it would be lovely to have some options for schedulers etc.. not so bothered about overclock/undervolt but I know lots of users will be!!
Great news. I love your Rom and kernel for the Xperia S and it be good to see all that come to the T.
Sent from my Xperia T using xda premium
I am also looking forward for overclocked kernel, because I found this cpu not to be the real dual core. 5 minutes of playing game and the second core switches off, because of temperature. So it would be nice for me, to have 1,8 GHz single core device and the second core could be turned off forever.
Hello people! I just succeded with rooting my LG Optimus 4X HD :victory: And the reason I did that was to increase the performance on my phone, but I couldn't find any good apps for that. I want suggestions about apps that can overclock EVERY CORE and not just a single one, please respond as soon as possible

have u done any overclocking in your whole life ? ...
you cant overclock from settings only one core. to overclock only one core u have to do a surgery to the cpu chip........
u cant overlock if the kernel does not support it. stock rom limit is 1500

Dude I just rooted my phone like 2 days ago so don't excpect me to be a pro at these stuff xD (I am a noob) But you didn't really answer my question tho :s
First,You need to install a kernel that supports overclocking, and after that you can use app like trickstermod or tegra overclock. But i would strongly suggest you to read more about rom,kernel,recovery etc. before asking such questions.

the phone doesnt have to do anything with the procedure u can overclock anything. from just a coffee machine to a kitchen , from a pc to a phone !! if a cpu has more than one core, u cant just overclock only one of them. I answered i told u the limit of the stock rom and kernel is 1500. u cant overclock. u must have a custom kernel that can support overclocking.
that means u need to unlock bootloader and flash at least a custom kernel if not a whole rom.
<<EDIT>> and just for the knowledge ! take for example samsung s3. it has a lower cpu frequency but the phone is little faster than our optimus. overclocking isnt only about rising the frequency. u can also overclock by slightly giving more voltage and faster correspondence. u have to read a lot to understand how it works. for example a mistake can make u have a slow 1700 cpu but a fast 1200 cpu. read read read read

I get it now, but I think I asked the question in a wrong way so let me tell you again how I was ACTUALLY thinking. What I want is to enable EVERY single core and make them have 1.5 GHz speed. How can I do that?

set governor to performance, set cpuquiet to userspace. you need trickstermod app & custom kernel in order to tune this.

And watch your battery drain in under an hour.
What have you been doing to actually have a point that you have thought a quad core 1.5ghz phone needs overclocking?

your cores are already at 1500. to set a perfomance governor to make them run permanently at 1500 will cause u a huge battery drain and cpu overheat. when u will go play a game the heat will enable automatically the cpu to rest so u will have actually around 1000 mhz speed. the cpu HAS to rest. the phones dont have many big fans inside to cool the board and the cpu. thats why people prefer ondemand governor usually. the cpu rests until the 1st core go to 90% usage or more and then the other cores are enabled too. when the cpu usage go below 90% one core is working again and when there isnt any need for cpu usage , the core goes down to 102 mhz.
overclocking
before you get your phone overclocked you should but in consideration that you may break your phone..over heating .... battery consumption.. don't look for performance alone >> you cant get performance with out battery drain or over heating >> just thing before you do that
You should look at how often cores 3&4 are even active. It's very rarely on my Nexus

ah c'mon he cant destroy the phone even if he wanted to. its not like he has the knowledge to decompile the kernel , change the proccessor limit to over 1700 and recompile it. so his limit is 1700 of iodak and werewolf and mokee. the thing is to understand how overclock works. he will figure it out eventually.

for the developers that know what to do , max for our phone is 1700. originally the safe overclocking at any cpu since many many years , is around 20%. after that it needs cooler. the better the cooler the more u can overclock.
Hi, trickster show me that my phone don't use the 1700 MHz. Y?
Sent from my LG-P880 using xda app-developers app
Probably it is not overclocked.
The stock higher operating frequency of p880 is 1500 MHz, and that is what your trickster diagram is showing.
So. Either your phone is notoverclocked, or in whatever kernel you are using maximum frequency is set to 1500 MHz.

Ehm, i have iodak v08 cm10.1.3 and cwm6.0.4.4
I'll check how to overclock the CPU.
May some one also look for a how-to if i don't find anything for overclocking my CPU
Thanks and kind regards

I've found it. Can some one explain to me how to fit this things?

I just got an m7 and I'm trying to figure out how to control the other CPU frequencies. I know on my old s3 I could just run echo them through a script but on here the only CPU with the cpufreq folder is cpu0, I can't seem to find anything on it so does anyone know how to do this?

If you're rooted, you can install a custom kernel like elemetal IX, this will allow you to set max frequency for each core. Just make sure you're using a compatible ROM, like ARHD. If you're looking for something that will allow on the fly adjustment, I'll have to find something else.

yeah with newer HTC devices you can't change freqs on the fly on stock kernel, because HTC have daemons and stuff to boost CPU and it will always reset it to stock 384-1728MHz
Either you need a kernel with pnpmgr (poewr and performance manager) ndisabled, freqs limited in the kernel source or one with aroma max freq choice

I hate to ask because I could find it myself but do you happen to know of a few other kernels that supports all core control or one you recommend? Elemental x is over a month dated and doesn't have a lot of useful extra governors imo. I'm running android revolution. So far the threads I've checked either don't mention they support it or just don't.

Extra governors are not needed since on demand does the job well, its like a hybrid interactive/ondemand though how it has post freqs etc
I'd recommend elemental, bulletproof, kangaroo (coughcough)
Imo limiting freq doesn't do much for battery.. But you can use power saver mode to limit to 1134mhz and its still super smooth
Extra bells and whistles are not needed and are buzzwords

Haha didn't see you were the Dev, I'll give it a run for awhile. And I just mostly don't like how the phone heats up when running at the higher frequencies/voltages but I know on my last phone limiting the CPU speeds seemed to have helped a lot. Overall I'd just rather have longer battery life over performance any day.
