[Q] Galaxy S Overclock to 1.2GHz with 2.2 JP6 Froyo Build?

Hi guys,
I've searched the forums and unfortunately have found nothing about the title.
Is there a known or upcoming overclock for the Galaxy S on Froyo 2.2? Obviously the Kernel Overclock below is only for Eclair but Froyo with 1.2GHz would be sweet!
http://forum.xda-developers.com/showthread.php?t=746343
Thanks!

the thing is we all use the samsung kernels and the froyo kernel is not released because firmwares aren't official so they're not forced to distribute the sources (leaks = mostly illegal - it's even breaking gpl)
i suppose u could get a 2.1 kernel to boot somehow, its probably mostly the init ramdisk which changes (?)

Until they get stable setcpu that works even with stock kernels overclocking is next to useless

How about now?

There is just one topic on this. And if you read atleast a couple of last msges you would know.

Just curious, is that overclock means drain more battery power? Then I guess it not good for smartphone isn't it?

Geeeezzz..... People here who want to overclock do not care about battery drain.
In most cases (use the Nexus One as a good example) they modified the kernel to undervolt to acceptable levels, and they were still able to overclock to 1.2Ghz stable. I saw no change in battery use when I had my Nexus One and overclocked with this UV method.

[Q] Overclock CPU to 1.2GHz

Can I overclock my captivate without loosing any data on my phone?
Edit: I'm running Froyo 2.2

Questions go in Q&A.

Please post questions in the q/a section or in the thread that you are refering to.
But to answer yes, flashing a kernel has no effect on data but if you have any sort of lagfix you may want to disable it just incase. Setirons froyo kernel has a universal lagfix and is supposed to work over other lagfixes of various types. The lagfix is managed in recovery mode which has been replaced with clockworkmod recovery.
For eclair roms unhelpful has a great kernel but a froyo stock kernel is just as fast in most areas. Also unhelpfuls kernel was not set to overclock by default. But you could set the gpu speed as well. The customizable clocks and volt started on version 1.4.1 version 1.7 was the latest and has voodoo lagfix.

By any chance you can post a link to that thread, where I can download overclocked kernel? I tried to search all evening yesterday, and wasn't sure which one is exactly for my phone.
Thank you, and sorry for posting in the wrong section...

Read the whole first post, especially the part about the modems.bin files. The 1.2 versions are considered more well tested, I'm not sure of the differences.
I odin flashed the kernel and did not change the modem.bin and people were complaining about poor audio quality in phone calls and my battery was draining, if you just flash the jpp modem.bin then you might not have the 850 mhz band so our may effect phone signal in some areas. There are instructions to get 850 mhz but it requires flashing to stock.

[Q] Kernel / Wolfson DAC: not sure what to do

I have installed COG 3.03 and find it great.
I want to unleash the power of the Wolfson DAC , and for that it seems I need a compatible kernel.When I installed the Voodoo App I got the message to do so.
Now I have search many, many, many threads, and I am MORE confused if anything; can someone point me towards the correct (and clear! 100 pages long threads make it very confusing to see what is the consensus) info for the following questions:
Which kernel should I choose?
How do I install it?
Do I HAVE to change my modem if I change the kernel?
Will the kernel swap have any incidence on future ROM choice I might do?
Will changing the kernel do anything to my reception (which is super great)?
Any help is appreciated; again, I tried understanding what to do by myself like a big boy, but I got to read so many threads in some many directions, that I can't make a clear choice....

Hmmm, isn't this what Supercurio is doing with his kernel drivers? Some kernels in here already have supercurio's code in, and you also need to use the app he made.

I think almost all recent kernels support it. If it says supports voodoo sound there you go. Try hardcores kernel.
Sent from my SAMSUNG-SGH-I897 using XDA App

Supercurio's audio thread has a link to all the kernels with Voodoo Sound. You can also just look for the phrase "Voodoo sound" in the short description.
Unfortunately, AFAIK every Voodoo sound kernel for Captivate is i9000/i9010-based, which means you'll have to switch modems (and lose bluetooth calls, unless you also switch to a different ROM) as well.
I'm sort of amazed no one put this and BLN into the native-Captivate Rogers Froyo source yet. DG said he had a test version of this combo *weeks* ago, but no release thread. And somehow no other kernel devs are interested...

Oh yeah, someone will kill this thread im sure cause it doesn't belong here. Should be in q and a.
Sent from my SAMSUNG-SGH-I897 using XDA App

Yeah, I see this thread being moved or locked soon.
I run Cognition 3.04 with hardcore's speedmod kernel, which has the Voodoo Sound 4 drivers in it. I use the T959D TLJL3 modem which gives me great reception and killer data speeds.
When you flash a new ROM, you'll probably be wiping and reinstalling everything anyway, so chances are you would have to flash whatever kernel/modem flavor you choose again anyway.
So:
Which kernel should I choose?
Any REORIENTED i9000 kernel with Voodoo Sound 4 will do.
How do I install it?
Most of them have the option to use either Odin or Clockworkmod Recovery. Since you're already using Cognition, make sure the Clockworkmod Recovery that you use has RED FONT. If you're installing the speedmod kernel it will be GREEN FONT thereafter.
Do I HAVE to change my modem if I change the kernel?
Since you're probably going to be flashing a reoriented i9000 kernel, i9000 modems will work best. I've had no problem running the JJ4 Captivate modem, but others have. Also, like I said above, the T959D TLJL3 modem is great.
Will the kernel swap have any incidence on future ROM choice I might do?
See above.
Will changing the kernel do anything to my reception (which is super great)?
This is certainly more affected by your modem than your kernel. I haven't seen kernels have any great effect on this.
HOWEVER, it's worth mentioning that i9000 kernels will chew up more battery than Captivate ones. Don't count on more than 20 hours of battery life... if you can even get that on a stock phone, LOL.

To flash a new kernal you can either use CWR or SGS kernal flasher from the market to install it. You do not have to change the modem when you change the kernal and when it comes to picking one that will work with voodoo you can usuall find that out in the original post.

[Q] Overlocking a SGS GT-I9000

Hello all
I just wanna know if there is any way to Overclock my processor
If there is.. i need the required kernel and programs please
PS: my device is Samsung Galaxy S GT-I9000, 2.3.3, Gingerbread.jpjv6

Search is your friend. Try looking in the development section yourself.

Thx, i found a question similar to mine

I am pretty much sure you need to be rooted for overclock. Are you?

lots of kernels which allow for OC. Several programs that allow you to monitor and set OC available on the market, most have a free version that you can try and then buy the pro version once you have made a choice. Some kernels allow for more user control and variance, others are more prescribed -- a lot of it is personal preference and so much is phone dependent: no 2 phones are the same in terms of what OC or UV settings they will sustain.
Lastly, most kernels will have their own group of users and advocates. Some have experimented extensively with alternate kernels, some less so, but all will have a passion for the kernel that is their personal preference. There really is no substitute for your own trial and error. Download 3 or 4 and try them with a stock rom -- root and use sgs kernel flasher -- flash a custom kernel, set your OC and use it for a day. Flash another, repeat the process and continue until you find your preference.
Having found the kernel you like best, then set about flashing a custom rom that plays nice with your chosen kernel.
Take about a week but at the end you will know what you like best and why.
Between flashes, clean cache and davlik cache -- keep a good backup of apps on your pc or external sd, and even better, completely cleanse the phone between kernels -- that will standardize things and allow each kernel to operate on a clean system.

Yes i am, and i used a lagfix "if that make difference".

Sorry i know i'm noob but i'm afraid to flash into a kernael which is not oc-able :S
So do i have to know any precautions first? or the CWM is enough to restore the original kernel?

its quite easy my friend download semaphore kernel 1.8.0 and flash it via odin or recovery and after flashing just go to semaphore script manager change ur overclock values.......too simple

And then use apps such Voltage Control (in the market) to select speed & voltage of the processor.

Thx all i appreciate all your help
and for guys having the same issue here's the topic that helped me alot..:

How can i speed up my galaxy s GT-i9000

Hi all on xda i'm wanting to improve my galaxy s i9000 speed, at the moment my phone runs at abt 960-1000 on quadrant standered which i know is rubbish, my galaxy s is on a stock rom & kernel (firmware 2.3.3, build number GINGERBREAD.XWJVH, kernel 2.6.35.7-i9000XWJVH-CL184813 [email protected] #2) updated using kies, I used to have it rooted but unrooted it don't know why what r my options regarding getting better results on quadrant any help on this topic would be much appreciated.
Thank you
John

install a custom rom,
if u want good battery, decent speed then install Darkys Rom,
if u want PURE speed (with stock android, without the touchwiz ui) then install CyanogenMod7
or just go over to the development section and experiment around with the Roms,
MAKE SURE THAT B4 U INSTALL A ROM, U ARE ROOTED BY INSTALLING A GINGERBREAD KERNEL THORUGH ODIN, AND THAT YOU KNOW HOW TO GET OUT OF A SITUATION IF U HAPPEN TO BRICK YOUR PHONE (LIKELY, BUT EASY TO FIX ) however, if u do anything to your phone and u dnt know how to fix it, im not responsible, ill try 2 help but wnt guarantee anythink
if i helped, be sure to click the "thanks" button

Forget quadrant, just a random number generator. High score in quadrant has value when you wanna show off, and at the same time let others know you really don't know.
I'm still going on XWJVH, happy user of rooted Semaphore kernel 1.8.2.
The included Semaphore app gives you access to a lot of tweaks, Voodoo color/sound and a smooth operating phone.
The latest leaked ROMs (XXJVS, XXJVT) still has bugs: phone FC, WIFI disconnect. If you feel brave and wanna try one of these ROMs, make sure to read what's fixed in their OP and latest posts for experience of users.

Try ThunderBolt! in my sig. Be sure to read the requirements and meet them before flashing

Stock jvt
or faaryabs f1 rom v13 that hopefully will be released today if you want more features.
talon or semaphore as kernel.
And thunderbolt tweaks.

delete unnecessary apps
root and delete unneccesary apps.

Flash stock JVT and Semaphore, then convert to EXT4.
my WiFi works fine, and for the Phone FC, just flash the JVT Phone Fix.
For me this is the best stock ROM that I've tried. Fast and stable, the browser has improved a lot.

use sgs chlorine, can remove all the stock apps in seconds

Root and install a Cooked rom, anyone will do better than the stock one.
And forget Quadrant, it's rubbish.

+1 on Pikachu01 Thunderbolt script. Running very much smoother on my SGS.

Mitra Rom is faster then other and use lagfix

small tip

If you use JVT with JVK modem the phone will operate amazingly, no phone fc, no wifi disconnect, great battery life + performance.
Good luck!

try miui mintberry

My advice would be first flash a few custom roms+kernels and see how that works for you.
If that isn't fast or smooth enough you could try tweaks like thunderbolt!
Sent from my GT-I9000

MIUI mint berry and via rom toolbox clocked into 1,3ghz

I´m on JVZ with Semaphore 2.1.1 and overclocked CPU (1300 mhz). This motor is fast, stable and smooth.

Hey!
2.3.6 is very good!
you should test at the beginn of your "Flash carrier" a few Roms + Kernels.

Look, if you want a rom that supports custom themes, mods and other tweaks, then go for stock JVT or some custom rom. But it is undeniable that gingerbread will always lag slightly on the galaxy s due to low ram. Heck, it even lacks on the nexus s.
In reality, if you want a lag-free (and I really mean LAG-FREE) rom, you should go for Froyo 2.2.1 roms. Froyo roms were meant for 512mb of ram, and they work flawlessly on the galaxy s. ZSJPK 2.2.1 never lagged on my SGS.
And just to be clear, ram is indeed the limiting factor to smoothness on our phone. On Gingerbread, free ram is less than 100mb after a day's usage, and so the phone has to constantly close and reopen background processes while you're using it. If I'm not mistaken, the default kernels begin to close apps and processes once ram drops below 64mb. Eg: Free ram is 100mb. You open the browser which uses 20mb, and then when you load facebook which uses another 20mb, the free ram has dropped below 60, so while processing the webpage, the cpu has to simultaneously close background processes. Then when you leave fb, the cpu reopens those processes. Hence, the phone lags.
But on Froyo, there's up to 180mb of ram on boot, and somehow ram consumption after prolonged use is not that high, so it can last for days with over 120mb of ram and hence never lags.
In conclusion, the only viable solution to lag that I have experienced so far is by using froyo 2.2.1 roms, especially the later builds like ZSJPK or the other one which name I cannot remember. Things like voodoo lagfixes don't really help (unless you're on eclair) and custom rom tweaks are really just placebo effects actually.

Wrong thread. Also there is tonnes of information a single google search away on how to root your phone. One way is to download Odin and then flash a rooted kernal such as CF-Root onto the phone from Download mode.
