[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.

A bit of using search never really hurt anyone before...

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

SetCPU 2.1.0

The new version of SetCPU seems to let us set CPU speeds for boot. Check it out in the market!

Downloading now. Yesterday, I rooted my friend's Fascinate. I got him the new version of SetCPU and the new OC'd StupidFast kernel. This explains how it kept the speeds at boot without the could not auto detect message.

I didnt realize it was out, still looks exactly the same to me

If you have one of the overclocked kernels do you need this app? I assumed both sped the processor up to the same speed?

[KERNEL][AOSP] invisiblek-2.6.37.6-4 [UPDATED: June 11 2011]

This kernel is for AOSP Gingerbread roms for the Incredible only!
Do not flash with ROM Manager, it has been known to give very strange issues on this phone, boot into recovery and manually flash it.
Things I add from stock (I believe in a mostly vanilla kernel with smaller mods to improve battery life and, in some situations, performance)
-havs (hybrid adaptive voltage scaling)
-smartass cpu governor (capped at 384mhz while screen is off)
-smb329 enabled (fast charge)
-no debugging (for smaller kernel size)
Use kernel manager from the market to get this (unless you want to be stubborn and do it yourself)
Pulled -5 and -6, not working as expected
invisiblek 2.6.37.6-4:
-Updated to latest cm-kernel source (latest change was May 30th)
-smartass and havs settings grabbed from the popular .32 #28 kernel which should help us get some decent battery life
Download
ENJOY!

We need to thank cyanogen, slayher, toastcfh, koush, cuviper, chad0989, cayniarb, vinylfreak89, seanzer, conap, jamezelle, and im sure others for all their help with this

FAQ:
Q: Will this work with Froyo?
A: Maybe, but probably not. I would recommend a .32 kernel since they are more stable at this time.
Q: My led turns green at 90% what gives? Please Fix!!
A: It always does that, been addressed a million times. Live with it
Q: Why is my cpu governor <x> when i set it to <y>?
A: <x> is probably the default (most roms set this in the ramdisk although the kernel does have a default setting, the ramdisk usually trumps it) youll have to re-set your governor after a reboot
Q: How can I help?
A: You can start by grabbing the source code from here
Q: What is havs?
A: from kingxklick's thread:
Code:
Also, a little info on HAVS and AVS:
The purpose of HAVS is to minimize the power used by the CPU by determining
and setting the optimal voltage. At the same time, the maximum voltage by
which HAVS can scale to is fixed to a specified voltage depending on the
CPU frequency in order to prevent scaling to a higher voltage than what is
normally used at a specified voltage. The optimal voltage is actively determined
for each frequency and temperature. HAVS actively adjusts the CPU voltage as the
CPU frequency and temperature changes.
Q: What is smartass?
A: The smartass governer drops drops the max cpu frequency when your screen is off (currently set to max 384mhz). It is very effective in saving battery life. (juice plotter is a good one for monitoring your battery life)

It's because you probably have a 004f touch controller. If you try to register more than 3 points on it, it won't function.

Thanks for bringing this out to the full community! Hopefully we can get the ball moving a bit better on development now.
Also great to see pretty much every active kernel dev for the Inc posting in here, and a lot of other people interested in getting this going.
I'll keep pitching in however I can.

I also greatly appreciate all you kernel devs hard work and I look forward to the development of this kernel...I am a willing tester just waiting for a build to come out so I can report on it

Zio Overclocking Question

Well iv had my Zio for a few months now and even with the 2.2 Update sometimes it seems to slow down and stutter.
I have been doing some research on Rooting my phone to get wifi tethering and the ability overclock my phone for better performance.
Now so far the Zio community on here seems to be very small so i dont expect an answer very fast so here is my question.
Has anyone with a Zio Managed to root there phone and overclock it? im not talking about some CRAZY overclock. im thinking in the 50-100MHz range. if so how has the performance increased? or has the performance Decreased? how is the battery life?

I have attempted such by manually editing some CPU files. I was able to successfully adjust the governor and changed from the stock 95% to 100% CPU threashold.
Sent from my Zio using XDA Premium App

So far I would say its a little faster. I definitely see a difference when opening apps and especially with the 2.3 launcher from the market.

What were your exact editing lines? I forgot which thread it was where you answered this question before.

I basically changed the governor to performance and threashold too 100. Actually overclocking the ZIO is giving me trouble when I try to go higher than 600000
Sent from my Zio using XDA Premium App

Correction. Governor must be set to on demand to edit the threashold.

You wont be able to get true over clocking until theres been kernel source released. Has that happened yet? New to this device.
If so, and someone is willing to do something with adb, I can work on getting an overclock kernel for you guys, but I wont be able to test it myself so it could be a bit dangerous.

As long as it isn't clocked any faster than 6.5 or 7... 7 would be risky.
Sent from my Zio using XDA Premium App

You cannot over clock the Zio at the moment. The Kernel does not support it. You can use an app to set it to 600mhz all the time. It usually stays at 600mhz on its on.

which is why I said if we had kernel source, I would work on it for you guys. Keep an eye out for it.
Once we ave source, if one of you can pull your current config for me, which i'll explain once its available, it shouldn't be too hard to clock up a little.

There is a overclock widget available that works great. When screen is locked it downclocks to what ever you set it too. Once unlocked it goes to 600 MHz.

but im gonna try and bump that 600 number up a little bit. Just need source code.

Tried to overclock witb droid. Fixed some permissions with clockwork it opened and ran just like setcpu. The app said the overclock module couldn't be opened because my device wasn't listed. Obviously.
Kyo M6000 Rooted with NoAds or Bloatware.

yeah the module is gonna be device specific.

I can't wait to see what this phone can do overclocked!
I had the Droid Incredible, iPhone 3G and neither could play the videos that I encoded for the ZIO without stuttering. The ZIO is playing the video files without stuttering with default player!
MP4/H.264/AVC/AAC LC
Video
800x480/4:3/29.97/1536
Audio
48100/2/160
I was just testing these settings on full movies just to see how bad the ZIO would stutter, to my surprise it played those as if it wanted more!
I will not keep those settings, as a full movie is over 1.5GB!
I might keep the video settings and use different audio settings, because the quality of the videos kick major butt!
I will be the beta tester for your Overclocking kernel option94!
I think it would do 750Mhz no problems, which would make this phone a beast! I wonder what the video sub system is in this unit?

Undervolt would be more needed right now, I don't think I need to squeeze anymore performance or battery life out of this thing. Once we get updated on GB and other things... then yeah overclock will be good. OC kernel right now would just make everyone complain even more about battery life.

Undervolt would be most excellent at this time

I'm not really worried about battery life my phone is plugged in 99% of the time because of my job just wondering if anything is out there that I missed or something on here

you cant undervolt on this phone.. maby on the inspire.. and i remember that setcpu didnt really undervolt on my ARHD inspire but whatever..
as it stands... untill someone makes a custom OC or UV or both kernel for the thrill, we just have to wait.. the only custom kernel i know of that kinda works is for the O3D but even it isnt OC or UV enabled..

so, again.. NO.. no you can't

I am assuming the Dev's are waiting for GB to get rolled out on this device before going ahead and messing around with an OC, UV kernel. Considering once that roll's out you would have to redo and remake a New Kernel which I would think would kinda defeat the purpose of making one at the moment considering GB "SHOULD" be out anytime now I think lol.

from what I've been reading on the Thrill development and O3D development forums, it has to do with the framework that LG uses..
the O3D and the Thrill uses a new tri- something system.. dual core + dual channel ram alternating between each other.. blah blah blah..
see.. the roms/ kernel that are out at the moment are basically the latest release of froyo that lg put out, with some mods done to the asthetics, and debranding or removing all the att apps that nobody really wants anyway.. no major re-programming has been done yet.. (devs are still figuring out this new system, or dont care to figure it out till a more familiar/popular release has come, namely Gingerbread or ICS..)
not to mention that the 3D aspect of the two phones requires its own kernel and as of yet, flashing another kernel on top of an existing one simply replaces the kernel.. the 3D needs the 2nd kernel to be flashed alongside the 2D kernel..
those two points are additionally preventing an OC or UV kernel since... well.. it would need to be re-written.. and since, as I have said.. the framework is still being figured out.. well... we'll just have to wait.. lol
at least thats what I have gathered from reading pretty much EVERY post in the two development sections..

The kernel source is available through LG. If someone wants to take the time to add in the ability to oc it can be done. I'm sure the same applies to UV (though I've never tried that on a kernel personally). I've looked into OCing the stock kernel a little bit and couldn't figure it out. Not quite as easy as it was on my Aria. The CPU tables were laid out real clear for that architecture. Not so much for the omap4 architecture. And I have as of yet not found anyone who's been able to help figure it out. I put it aside to concentrate on porting gb, which has been very slow rolling due to time constraints.
As for waiting for gingerbread, the kernel wont change since we already have the gingerbread kernel. Whether or not this kernel will be compatible with ICS I have no idea.
