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.

Hey,
So I'm interested in overclocking my I9000M, but I wasn't sure if I could flash a I9000 kernel onto my phone (how much difference does that "M" make?)
If anyone could link me to a good kernel for overclocking my I9000M, and maybe a quick how-to, I would very much so appreciate it. Thanks!
SetCPU is an app (which requires root) that allows you to control the speed your CPU operates at.
I highly recommend not flashing any version of Froyo. There has been countless problems with unofficial versions of Froyo with the i9000M which render the phone useless.

Thanks for the Froyo advice! I'm aware that SetCPU lets you tweak the speeds that your CPU runs at, but I was under the impression that I needed to flash a different kernel to allow SetCPU to go over 1ghz—was this an incorrect assumption? Can I simply install SetCPU and overclock my phone?
Either way, I'd prefer to use an optimized OC/UV kernel, so could anyone answer my original question: can I use i9000 kernels on my i9000m?
im on unhelpful kernel v1.7 with cognition, with voodoo lag fix. i dont know why setcpu isnt detecting my freq_volt_table file. can someone please help me out, i dont know what to do. thanks
Flash a 2.2 rom with an oc kernel. much better and you don't have to mess with the freq volt table anymore or setcpu
newter thanks, would you kindly point me in the direction of which 2.2 rom on this site right now is the best and easy to flash? thanks
Purely subjective obviously but serendipity, docs, darkys, perception phoenix are all good as I am sure others are as well. Kernel options if you aren't happy with what is in the Rom are glitterballs and setirons which are oc/uv capable. Just look through the development section. They're all easy to flash through clockwork recovery and kernel swaps are a breeze with sgs kernel flasher app.

newter thanks again for a response. im looking at using phoenix. my question now is do i need to use odin to return myphone to stock and then download rom manager and flash the zip file? then how would i go about overclocking and underclcoking? and after installing phoenix can i use odin later if i want to restore my phone to stock?
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.

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.

I am using cog 3.04 with the firebird 2 ver1 and jk4 modem to use voodoo control. I flash back to stock cog.3.04 kernel & modem when I want to use bluetooth. Speed mod kernel caused my phone issues. Seems to be trial and error with each phone, good luck with your set up
is there any app that can help me overclock the Hummingbird to 1.2ghz
did some 1 actually did it? how much VSEL on 1.2ghz?
i dont want to flash anything..

Stock kernel doesn't support overclock . You have to insert a custom one to get access to oc.
Bty, wrong section maybe

First this is the development section, please post questions in the Q&A section.
I do not believe there is any app that will do the overclocking if you do not want to flash anything. The overclock option has to be enabled in the kernel and stock kernel does not have that option.
using the PilotX 4.0 rom with speedmod hardcore 13E kernel
Pilot x rom?
Speedmod does not let you oc/uv. You would need to flash a new kernel that allows overclocking, and then download Voltage control to enable / control it.
Btw, if you are on a rom / kernel that is other than stock, you have already flashed... So why do you not want to flash again?
You could try this, no need to flash anything

by mean "flashing" i meant other rom to enable the OC feature.
what about the exect values to 1.2ghz?

Onix 2.0.5 is good. Try that, install it via CWM.
Anyway,
Ask the dev to post the ROM over at the development section. ;D

I have an AT&T Samsung Captivate with Serendipity+Redrom installed. I want to use a custom kernel for overclocking to 1.2GHz. (http://forum.xda-developers.com/showthread.php?t=746343). I have tried flashing this with Odin before installing Serenpity and it works but then Serendipity gets rid of it. If I install serendipity first then the phone does not even boot ofter flashing the kernel with Odin. Does anyone know how to get Serendipity to work with the 1.2GHz overclock?
When you flash Serendipity that replaces any kernel you had with the one that comes with the ROM. Have you tried flashing a kernel from CWM.. one that works with serendipity and is OC capable?
no such kernel
I have looked and this is the only overclocked kernel that I can find. If there is a kernel that can use CWM I cant find it.
ohh.. i did not know that. Have you tried asking the mikeymike if there is an OC kernel that works with his ROM?
dont know how
Sorry I'm kind of a noob when it comes to stuff like this but I have no idea how to contact Mikeymike01, I don't see any contact info on the serendipity website.
here on XDA.. Go to the Serendipity thread and just ask in the thread. You may even get some help on installing the kernel you are trying to use.
your link is for 2.1 Eclair, and will not work on Serendipity.....i dont understand how you cant find an overclock kernel in the sea of kernels in the dev section....i mean, the titles of the threads start with [KERNEL]
