Freezes when overclocking. - Galaxy S I9000 Q&A, Help & Troubleshooting

So there's the problem. If I overclock my phone to 1.2GHz (or 1.4), it freezes at some point when using it (it can freeze on first seconds of booting up or it can freeze after few days). Battery pull is necessary to reboot it, of course. After that it's working agian but there's a question of time when will it freeze again.
Running CM10 stable, Mackay kernel, using NSTools to OC.
Sent from SGS GT-i9000 using magic.

Some phones (like mine) can't handle too much overclock. Most phones can only handle 114% OC to have still stable operation.
Device: GT-i9000
Rom: JB 4.2.1 C-RoM Mix v4
Kernel: Mackay 0.232
Baseband: I9000DXJV9

How do I set the lower value of hertz? Is there any other OC controlling apps for this kernel?
Sent from SGS GT-i9000 using magic.

Sorry, in Mackay kernel the intermediate OC 1100 & 1300MHz were removed by its Developer due to instabilities being experienced by users.
If you want a lower OC, you can use another kernel like Semaphore and Devil.
Device: GT-i9000
Rom: JB 4.2.1 C-RoM Mix v5
Kernel: Mackay 0.232
Baseband: I9000DXJV9

LiveOC or normal? Hardly any SGS handles any more than 114% LiveOC, but if it's not then you might want to try devil kernel for OC stability...

Mine is solid at 124% live oc using semaphore

My semaphore manager app doesn't even let me go past 120%
124%, that's great, but most of what I've seen here and heard from friends makes me think you're one of the lucky exceptions...
Do you adjust voltage?

I used semaphore +nstools without adjusting voltages. Definitely my phone is a lucky exception. It could handle 1.6ghz overclock using glitch kernel (which, sadly, isn't supported anymore)

Darkcore kernel over clock..

Hi. I just looked at the dev section but couldn't find the right darkcore kernel that would allow me to overclock my phone. Does anyone know a modded darkcore kernel that can be overclocked?? And is compatible with darkys rom 10.2 extreme edition?? Thanks...

Quite a few peoples are using Semaphore dude! Works a treat with Darkys 10.2.
I think Semaphore JVQ_1.3.3 in particular as Darkys is JVQ based.
DarkCore doesn't support OC / UV.
Semaphore 1.4 worked perfectly when I was on Darky 10.2. Didn't try OC/UV though.
Galaxian has been said to work nice with 10.2 aswell and has UV/OC

Semaphore allow OC. And it is stable too.
About phone:

I9000XXJVQ
Semaphore_JVQ_1.3.3
DarkyROM JVQ v10.2
(GO Launcher, GO SMS, GO Contact)
Check the DarkyRom forums beta rom section for the XXJVR rom (my url's get truncated so the title is here - [ROM][CWM][SGS+Cappy] DarkyROM XXJVR BASE
).
Download Tegrak app from Market which will still allow you to overclock. There have been a few iterations and believe Dark Core 3.0 is latest version. I am at DC 2.9.3 and was able to OC to 1.1 (1.2 hung on me but I understand am on a beta).
While I have SetCPU, I cannot OC but Tegrak app works on Dark Core (don't know how).
I checked the tegrak overclock app. I have the ultimate version and saw that I can set cpu freq to 2000 I think... I have the dark core from darky 10.2. I am not sure what.values to set on the app to have either overclock of 1100 or 1200 freq..

So far haven't gotten stable results passed 1.1. Keep getting hangs which need reboot. Even suspect about 1.1 so have kept quiet. Be curious what others have as well.

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

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.

Glad to hear it. No problem
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.

event does i set oc back to 100. i solve this by change kernel to semaphore 2.4.0. hope this will help.

Kernel for performance

Hello all,
I am currently running the CM10.1 (Android 4.2.1) with stock kernel. I've been searching for a kernel to install but that's where I've encountered a problem - I'm pretty new here..
So, what are your suggestions for a kernel? The only thing I care is performance!
Sent from my GT-I9000 using xda premium
use Semaphore JB 2.9.0 kernel
f.e. I can overclock my phone to 120% to all

+1 for semaphore 2.9, 120 live OC stable with mackay ROM 2.3.2. Benchmarks around 4400...have achieved 4600 once.
Sent from my GT-I9000 using xda premium
i use semaphore 2.9.0s they is very stable on my phone with 120% live oc and the Lazerdroid Tweak from Lenarox
I tested 3 Roms with this combination
Use Mackay kernel its faster than sema

Test both kernel and then you see what goes better with you
I've tested all kernels and for me the best performing is Devil.

OC Voltages!! please!

Hi I'm using MiUi 4.1.2 with Mackay Kernel and I want to OC it from 1000 to 1200 but it seems my phone has a lot of "auto-reboots" so anyone know's which custom voltages i need to enter in NSTOOLS?
Thanks in advance!
P.S- OC Might harm my SGS?
which vers of Mackay do you use?
I had also a few auto reboots, but after a few days it stops
