[Q] Undervolting my i9000 - Galaxy S I9000 Q&A, Help & Troubleshooting

Hey all..
So i'm following this thread and it asks to find an undervolted kernel :/
Well.. I don't have one.. as well as my ROM is stock JPJV6 GB.. and it's lag fixed.. with vodoo kernel
I looked it up and found that OC/UV Beater2 can undervolt you kernel but it says that my kernel doesn't support it.. what do I do now??

You need to flash a kernel that supports under volting. Eg Semaphore.

Do I have to disable the lagfix? and does Semaphore has lagfix?

I think everyone is using voodoo lag fix nowadays, so it should be fine even if you leave lag fix on. However, make sure you are flashing the version for Samsung rom, not AOSP roms.

Overclocking Onecosmic's ICS RC3

I flashed Onecosmic's ICS RC3 and Have downloaded NStools from market but so far all the frequencies I've tried for Overclocking are not stable.So I was wondering if someone has succeded in overclocking the rom with stability could share their values here. All the stuff,live oc,processor frequency and voltages.
Hi. Have you read this guide ?
why do you want to oc, first wait til there is a stable version of ICS ;-)
Im running Onecosmic's ICS RC3 and allready now its fast

Ya I've read that and I've triead almost all frequencies shbmitted their and i can't get a stable configuration on any of them.And that is for glitch kernel and Onecosmic's RC3 is using Platypus so i thought that maybe I can get some different settings that will work. Anyways,thanx.
Do you have problems with oc only in ICS? Maybe try another kernel! I used RC2.11 with a few different kernels, but a little oc (1200+5%live oc) always worked for me.
I overclocked it to 1460

So from what i understand u have not used live oc and have just oc'ed ur processor?
End result???
So did you finally succeed? I have tried quite a few voltages, and the maximum my phone has stayed up with any OC/Custom voltage setting is a few minutes.

Best kernel for gingerbread MIUI?

I run Miui.us build 2.3.23 and it runs the shade.toxygene CyanogenMod kernel. Is there a better kernel I can get?

It's not that I'm not satisfied with the kernel I run, it's just that I'm certain there's some better one out there.
EDIT: What do you think of the kernel labeled Tiamat_N1-v4.1.0? From here: http://tiamat-dev.com/mahimahi/
the kernel you mentioned is what i am currently using as testing so far its working good with MIUI 2.3.23 and it offers up to 1.2GHZ overclocking which is not stable on my nexus at least

Any overclock beyond 1113 Mhz is unstable.

sry for my noob question. but is the kernel jus for oc purpose or for overall performance(battery life,call audio quality,smoothness etc)?
cos i am happy with stock kernel. no issues at all
Sent from my Nexus One using Tapatalk
the stock kernel was good for me to it did not give me any trouble but i like to mess around with my devices the change log for the kernel can be found here
Code:
http://tiamat-dev.com/8x50-changes/
as you can see there are a few improvements to the kernel with each update
I have been having 3G mobile network issue with CM7 base ROM. On certain location, I cannot download and make or receive calls. my 3G icon arrows show upload activities but no download happening. My ISP name (Maxis Malaysia) showing as normal. I upgraded to CM7.2, tried Kang ROM, preshoot kernel and change new SIM card but doesn't help. Anyone has any ideas on this problem? ROM or Kernel issue? Thank you.

Wildmonks [Kernel] [2.6.38.8 (CM7)] HAVS/SVS + 1152MHz (09/17/11)
is the best I have seen so far, used it for months and often thought I was glad I did because it seemed more stable than stock !

[Q] i need help

hello
so here.my friend has samsung galaxy s I9000,and he gave it to me to flash it.now, wont have problems with flashing since im experienced in odin and cwm,but i would need someone to tell me wich kernels and roms should i use.
what i need:best gingerbread kernels,and best ics kernels.ill try many roms in this two days i would have this phone,but my only concern is the kernels.
i am also thinking about to make MegaBassBeats for GS gingerbread users.but i would need your help then.thanks
All ics kernels are great, midnight, semaphore, devil and glitch. Personally I find midnight and semaphore most stable.
Sent from my GT-I9000 using Tapatalk 2
Try slim ics, doc master with glitch or devil kernel

That's for gb, I don't see the point in using gb still.
ICS is stable and by far superior, slim ICS with devil or midnight kernel. Anyone would love that combo.
Sent from my I9000 running Slim ICS 3.6.
I tried both,and cm7 is faster.and got everything working.you need to understand that 3.0 kernel on gingerbread isnt a small thing.its above-average

Which is the best kernel.... safe kernel...????

Sent from my GT-N7000 using xda app-developers app
for me, its NoteCore kernel, it has the MMC_CAP_ERASE line removed as well as the cwm.zip bug too. Making it 2x safer than the rest
Its also fcuking awesome !!!
What bout Franco kernel is it safe....
Sent from my GT-N7000 using xda app-developers app
its safe from the MMC_CAP_ERASE bug which triggers the brickbug, But im not sure about the cwm.zip bug, its only just been discovered...
I havent read too much into it to be honest, Ive always used NoteCore kernels and I know its double safe so I dont worry about it
Check it out if you're concerned , Its stickied in the General section

and yes it awesome kernel with great perfomance too
Hi I am really using my note heavy work, now I am using crash rom v8 but not stable, would you mind to advice me which rom stock or custom rom doesn't matter I can use with notecore kernel without any lag of phone and dialer and the others. Thx

+1 for CleaNote, Combine it with NoteCore kernel and you will feel like your handling a triple quad core phone
I cannot stress how fast and stable these 2 are any one with doubts should definitely flash them !

Any reason to change kernels in CM10?

I'm running CM10 nightly, and wondering if I will gain any performance improvement (without OC) and longer battery life if I flash one of the alternative kernels on XDA (looking at Devil and Semaphore as those seem to be the most popular)?
yes and yes, but it all depends on how you configure the kernel options and how you use your SGS...
Sent from my GT-I9000 using xda app-developers app
yes, definitely!
but to get the "best" result, of course you have to let it settle for atleast 3 days..
here is a youtube link on how to flash them: http://www.youtube.com/watch?v=kCBN-_zu5cY
i hope this helps,
cheers
Thanks for the answers. I was hoping for recommendations, do you have any?
Semaphore is looking good to me. Opinions?
I'd go with semaphore for ICS...
But for CM10 I'd use Devil..
But that's just me
Sent from my GT-I9000 using Tapatalk 2
If you want stability then semaphore.But if you want more tricks to make your phone even faster it is devil of course. There is one more kernel to try Mackay.
Test each to get the right one for you.
Sent from my GT-I9000 using xda premium
Semaphore is the one you need .
What else from having great speed with stability. Yeah, maybe Devil could provide some more speed, which is unnoticeable, for me at least.( except the benchmark tests )
Sema is the most stable one.
But devil isn't bad too.
Try them. But give your phone about 5 minutes after flashing and don't be frustrated when it's a bit laggy after first reboot.
Last days I tryed makay. --> I prefer sema
Sent from my GT-I9000 using xda app-developers app
I prefer devil. My phone still lasts a whole day (7am - 12pm) and is much faster. I like all the options.
Sent from my GT-I9000 using xda premium
On JB roms i always use the devil kernel even if the Semaphore is a very good kernel, Devil kernel allows me to entirely use my phone's habilities with no more battery drain than Sema
you will instantly notice more speed and smoothness with flashing semaphoer kernel.
+ more speed if you set up liveOC to 114%
Does anyone have any links? I'm using CM10 nightly and need a kernel so that BLM and Voodoo sound will work. I tried the latest semaphore 2.8.0 via Odin but the phone would not boot.

You should read the description more carefully. The 2.8 kernel is for JB 4.2 not CM10. Flash the 2.6.5 kernel.

I have few more questions...will i flash only kernel or i need to flash the rom together with kenrel...and can i use odin to flash kernel?Sorry for all thease questions im noob guy in this area
You don't have to flash a rom if you're happy with the one you're using. And you can download .zip's and flash in CWM if you like, but I've found that the only times I've ever got into a boot loop when flashing a kernel are by doing it this way. Not that it has happened often. But for that reason, i prefer to flash my kernels .tar in odin, I've never had a problem doing it that way, but whatever way you choose to do it take a nandroid first, just in case.

Download semaphore manager app if you haven't already done so. Also, if you used the (s) version, you need to make sure and select the bigmem option in semaphore manager and reboot for settings to take effect. Then you have 403MB RAM.
