Have you done undervolt also?
This is the main cause.
The problem is from your kernel
what kernel are you on, to overclock the best kernel is siyah kernel for ics roms
SiyahKernel for SGS2 | "One kernel to rule them all"
www.gokhanmoral.com
once you do this you should't have a problem anymore
if i helped press thx

Said the man who just posted that there are no stable ICS ROMs.
Great advice about overclocking though - the OP obviously really wants to, he just ended up underclocking buy some twist of fate... Good you're here to fix it for him
You cannot possibly be for real.
may i know how to undervolt and what app should i need to use to underclocking/overclocking?
i used battery saver pro to underclocking but my phone hang and force shutdown

Hi everyone,
I'm really really sorry for asking a seemingly stupid question like this, but I browsed the forum and asked google to no avail:
How do I activate/enable the smartAssV2 governor (or any others for that matter)? SetCPU or CPU Master show only 4 governors, I think those are the default ones. But if I'm not mistaken, the other govenors (looking for smartassv2 myself) should be included in CM9, right? I have a rooted SGS2 and the CM9 "final" installed. Didn't find the govenors on my SGS+ either, but didn't think too much about it.
I also tried downloading the governor and installing it in CWM, but that just gave me an error...
hope somebody can help....
Different kernels have different governors. Try looking through some kernel threads to see which ones have the governors you need. Siyah has SmartassV2, amongst many others.

LOL I was asking OP
Well, at first I was using the stock CM9 kernel (which should have the smartassv2 governor I think), now I'm using the Fluxi kernel (which also has the governor, according to the description) - but with neither of these kernels I can select anything else than "interactive", "conservative", "ondemand" and "performance"...
Oh, and btw, I already looked in lib/modules, and there is no module for smartassV2 - but then again, maybe it is compiled into the kernel? how can I check this?
I think this is something really simple that I missed, but all the tutorials also just say "install CM9, select smartassV2 as governor..." so I'm assuming it should just be there?
Installed the Dorimax kernel, now I have other governors...which is OK, but I'm still confused as to why no other governors showed for the CM9 kernel. I can live with this "solution" though.
I too face a similar problem. I flashed siyah kernel in my sgs2 and couldn't find smartassv2 governor. I tried setcpu, no frills cpu and even stweaks. I have all other governors like lulzactive and hotplug but no smartassv2. Is there a way to find it? This is driving me crazy for days.
Sorry if i posted in wrong section but this thread was related.
Thanks in advance.

Any productions by me are not, and will never be donation ware. However, I have put many hours into the development of this kernel, and will continue to do so for the foreseeable future. Your generosity - if you feel like showing it - is deeply appreciated. I do how ever ask that you hit the thanks button.
OverClock & UnderVoltOver clock and Under volt at your own risk. not every device and chipset are the same. what works might not work for others. I will not be supporting oc/uv any further. Dont ask for a higher overclock. Are chipset has the coding for 1.7ghz and all i did was enable it. This dosnt mean its safe to do so. If you expirence any problems with with oc/uv return your phone to stock settings. I will not help you any further.

I can n will when they get everything working. There's no point of me to build a kernel when there still updating it. Allot of tweaks are sideway found in cfx. You may have better results by asking him to include the faux sound enhancements

I haven't looked into the keys. I turn them off n use the soft keys. How ever of you goto settings/display/front key lights n turn them on to always they will stay on the hole time the screen is on n turn off with screen

I have great battery life with that ROM, but I'm running Trinity kernel. I'd suggest trying a custom kernel like Trinity or KTmanta.

Here's the thread for Trinity http://forum.xda-developers.com/showthread.php?t=2083885
Sent from my Nexus 10 using xda app-developers app
While that ROM gets ok battery life, it isnt the best there is. Smaller ROMs with less features tend to get more battery as they dont try and do so much stuff. But still, I dont see a problem with AOKP PUB, it still is ok enough on battery. The kernel has a lot to do with battery since it controls your CPU speed, scheduler (which some use more or less CPU), and GPU, as well as voltages. So the right kernel combo can give much better or worse battery life.
Alright so i booted into recovery mode and installed the trinity kernel. Now once i cleared cache/dalvik and fixed permissions, i have booted up and in settings it still says the kernel is: 3.4.5-g3e87446-dirty. Its the same as before, did i do something wrong?
Its possible the ROM you are on has Trinity installed by default, or the kernel didnt install right. Also you dont need to fix permissions.
I'd try and reflash the kernel again, and post back if it doesn't work.

CleanROM with stock Kernel has great battery life on mine.
Nope everything working fine, but i cant seem to get this to work. Ill try the KTmanta kernel and post back.
Alright so i got the KTmanta kernel to work, so i guess the trinity one doesnt work with mine? Now how can i see how much of a battery improvement this made? Is there an app or something? Thanks guys
Kernel and app in the first link, premade settings in the second link if you want them. Settings get placed in the tweaking apps' folder and loaded from within the app itself

http://forum.xda-developers.com/showpost.php?p=40087947&postcount=2741
What does that app do specifically?
Allows you to tweak all kernel related settings
All i really need is better battery life lol
Then use enigma1987 settings as a base for further optimization. Read the forum to get the knowledge about the different options that the Tweaker app offers and adjust them on your own taste. I am getting an average of 8h+ screen on time with good performance
Well when the next KTManta kernel version comes out I will be putting out a new version of the "Butterlicious" settings as there are major changes to the kernel. In addition I will also post a pre-made settings file designed entirely around best battery life. Talha746, can you please list out the things you do most on your tablet? And any games you play regularly?
I basically watch videos and play emulators and surf the web. But as of installing this kernel, i cant even play a single video file! It keeps crashing and turning off my device, any ideas?
After many many attempts of making my own scripts (and failing horribly), I found a decent base and created multiple scripts that use the conservative governor for better battery life and a mixture of performance and battery life. I'll be posting a couple variants for different kernels.
You'll need SManager or ROM Toolbox to run these scripts.
These will create MUCH BETTER CPU scaling. You might notice slight, but quick, lag when the screen transitions under the performance and balanced scripts. The battery saving one will definitely have lag in it.
I personally prefer the balanced tweaks.
NEW SCRIPTS TO WORK WITH ALL KERNELS THAT SUPPORT THE CONSERVATIVE GOVERNOR!
