[Q] Overclocking the Galaxy

Now that the kernel source is available, won't we be able to overclock our mobiles?
Guess i got a little bit envious with all the overclocking that has being going on with other phones.

So is it possible yet.

Been possible for last 3months. Just find a kernel with oc support and get setcpu. Frankly its not worth it as setcpu is a piece of **** app that make your system unstable. As other poster said. Do a damn search

But for froyo? Maybe is asking for it.

maybe someone with the tallents could have a look into this OC method they use for droid x and milestone using a kernel module, this would enable us to overclock any froyo kernel.

It would be nice to have it in the kernel. 100 to 1200 that the system controlling like it already do. No setcpu crap.

also setcpu is not to blame for the problems, as it runs just well on galaxy i7500 for overclocking. i´m not sure what the problem wit it is on SGS, but i´m pretty its not setcpu´s fault

The problem is that SGS doesn't like different CPU governors! It will only work if you don't touch the governor settings! At least that is what I have found to work in the Eclair builds!

Seems ignorance is bliss for some of our fellow xda folks. SetCPU is not even needed for those oc kernels unless you want to change scaling from default schema. It really don't contribute to the unstablity, just that the kernels seemed inefficient.

I agree. Don't install SetCPU and the kernel is reasonably stable, but crashes miserably when running cup intensive apps. We have to work harder developing a kernel which works well for our hardware.

kernel was very much stable. It is just that hummingbird is bad for overclocking. Not all phones can be overclocked, sadly.

I can understand what you are suggesting, however why was it still unstable when I tried to disable 1.2GHz or 1.13GHz frequency keeping the original scaling and running at 1GHz or less??

Is that 0.2 bump really noticeable?

dont know which version you used.
1.13 was quite old. All recent versions were 1.2. Anyway, nevermind =)

Yeah, do want a OC'able kernel - the 1.2GHz kernels for Éclair were always stable enough for me if I didn't try to UV it.

Id be open to using a 1.2Ghz OC if its 100% stable and no wake-up bugs and ofcourse should not affect the life of my CPU that much and should not drain my battery more than 10% faster

[kernel[05.13.2011][bfq][oc]2.6.32.9

Hey folks,
P-Funk asked me to take a look at the kernel source for the Zio and see what I could make of it.
I won't lie to you, its not pretty. However, determination usually prevails, and so I present you with a kernel, currently beta, with minimal support (I don't have a Zio).
Use at your own risk! I, nor anyone else is responsible for damage done from, or to your device. Your device may become unstable. Your cat may marry your dog, and your gerbil may elope with your daughter or son. This is not my fault.
Features
2.6.32.9 source built
overclocked to 748mhz
lowmemkiller driver patches and tweaks
Boots at stock 600mhz speed. You must use setcpu to overclock.
sdcard read speed tweak
init.d support
smartass and interactive governors.
bfq i/o scheduler added and set as default.
kernel is pre-rooted, and will start usb debugging by default.
swap support
Download URL:
http://www.multiupload.com/2GQA0JD1VS
How to install:
Download file, place on sdcard, boot clockwrok recovery and flash.
Please note: I am trying to upload source to a mercurial repo, but it is having issues. I have a trouble ticket in with bitbucket. The source is too big to upload to github for free. If I do not hear back from them, I will tarball the source and upload it that way.
Thanks:
Every single soul in IRC #openzio who broke their phones testing stuff for me

Thanks. Testing now.

OK I flashed the Kernel and I am stuck at the Kyocera splash screen. Dont understand why its not booting up.

For those that cannot boot this, SPz0 has a more stable version that he will be releasing with his rom.
729mhz seems to be the most stable clockspeed for this device.

for those that are wondering, the smartass governor eliminates the need for a "screen off" profile by automatically capping the CPU speed when the screen is off/phone goes to sleep.
More info.
Smartass will also cap the max frequency when sleeping to 352Mhz (or if your min frequency is higher than 352 – why?! – it will cap it to your min frequency). Lets take for example the 528/176 kernel, it will sleep at 352/176. No need for sleep profiles any more!

In other words, SetCPU would only be needed to OC (or use the Overclock widget, whatever floats your cookies).

So this kernel is ready to use or wait? A little confused from your post.

No this one is unstable but there is one working and being tested as we speak, it should be released soon.

Would this work on a sprint device?

Great job man, and much thanks from all of us Zio owners for your time and effort, thanks Adrynalyne!
Any reason anyone can think of why or what in the kernel would cause 2d graphics to choke out so bad? I was scoring 110-120 prior to OCing, and now 2d is scoring 70 if I'm lucky. Any thoughts or ideas?

I thought this device could run at 800mhz??? I thought wrong. Cheap cpu they are using.

Why on earth are you such an ungrateful douchebag?
Why not contribute something constructive instead of showing people how douchey you can be...
OnTopic:
749Mhz ran flawless for me. It seems to be random on who 749mhz freezes with.
@sinisin: did you flash 749oc with the openzio rom?
My ROM has Adrynalyne's stable 729Mhz overclock for those interested.

Hey Adrynalyne:
Think I could grab an 800Mhz OC from you at some point? I really wanna push the boundaries of this cpu.
Just a straight step from 748 to 800Mhz would be sufficient.
I want to see if I can get it to run stable @ 800Mhz.

I think that would need some voltage tweaks to reach 800mhz

All the cool kids have cricket
Cricket users are lucky to have any development, my roommates told me there wouldn't be any Dev's interested in the ZIO. I think the main issue you're encountering is any Dev who has the droid options available on sprint, is not going to choose the ZIO for their personal phone or development. You're best bet is to start reading like crazy and head the development of the sprint side of things yourself or upgrade to a phone that has active development.

Over Clock on Glitch Kernel

Can someone tell me how to over clock with v14 B6 just where to set things at?
Sent from my SGH-I897 using XDA

There is an app called "pimp my cpu" (I believe it's in the market) that will allow you to easily overclock the Glitch kernel. Might want to give that whirl.

I got it but the interface is confusing I kinda wanna one click thing lol
Sent from my SGH-I897 using XDA

I don't have it on my phone right now, but I believe all you have to do is open the app, pick a maximum cpu frequency (e.g. 1400 MHz) and long-click on it. It will pop up "set as max", and when you click that, it will put that as your max speed until you reboot.
If you want to go farther than that, you can create profiles that will load on startup, and tweak the undervoltage settings, but for a simple overclocking, you're actually in a good place with PMC.

The best one for glitch kernel is the nstools

Governor problem

Hi everyone, as i have been starting to fiddle around with governors i discovered that my setting won't stick and I'll have to reset them after rebooting, what could be the solution to it?
Also after researching it seem the better governor is smartassV2? Should i change any voltage or GHz for balanced performance and battery life?
Thanks all for helping out yet again:beer:

What app are you using to do this? Try trickstermod or daemon controller
And have a look at the guide linked in my signature, that might answer your questions about overclocking and undervolting
You'll have to look on a pc or on a browser on your phone

Never, ever, ****ing ever set your clock speed apps to set on boot.
Why? If you set up a frequency that your device cannot handle it will set these frequencies as soon as your phone hits the loading screen. You will not be able to boot your device as the clock settings will kick in immediately and freeze your system.

If you dont check that option the settings will revert to default setting when u reboot

Most roms running ics or greater have built in safety, so if the phone force closes set on boot will not apply. It is perfectly safe to set your governors and I/o on these roms. Check for info about current Rom you are running, if it has this feature go nuts and test the limits of your phone . Do your research peoples, can't stress that enough, find out what you can about your phone and current rom/radio/kernal and you won't hurt your phone. Fail to do so and risk bricking your device, its that simple.
