First of all, I got interested in overclocking because I've read that it helps boost the performance of android devices.
Now, Having no experience at all, I have some queries and questions about this feature:
1. Supposing that I have already downloaded an OC with my preferred frequency, Do I have to flash to be able to apply an OC Kernel in my device? Or do I just have to update it from CWM?
2. What does this term mean? :
"use no-Frills for OC and I/O setting"
3. If ever the OC I have applied is unstable, how would I be able to revert it to 600MHz again?
I hope you guys could help me with my doubts.
Thanks in Advance!
Dude never overclock a device...it decreases the life of the device and who the heck told u that improves the performance of the device???It doesn't improve just causes more problems!!!!!
Hit The Thanks Button if I have Helped.

Stop lying . It may decrease the life of your device if you overclock dangerously (too high for the processor to handle). It does increase performance.

1. You just set your frequency in the app.
2. No frills is an app. Whoever stated that is just saying you should use that app to do it (thier preference).
3. If you use SetCPU, you can create an update.zip file which allows you to set it back to the default frequency via recovery (if your device can't boot).

Are you sure? This is far contrary in the threads that I've read. Does anyone else agree with this?
Totally confusing. HELP!!
It's ur device ur wish. Any overclocking involes a lot of danger. Set it too high for the cpu to handle it might explode(personal experince). I overclocked my device and it exploded....So it's ur wish.

Phew! At last. Something worth reading.
Thanks for the answers! But I have another follow up question.
I found this thread :
[kernel] Cm7 OC kernel with all feature
So what does this mean? Why do I have to download it from there instead of using the app to change the frequency?

Because not all kernels have OC/UC capabilities. You have to download and flash a kernel that allows it.

Yeah right! I forgot about that.
Maybe my Samsung Galaxy Fit doesn't have that capability that's why they created that thread in our section.

It is capable. That kernel will allow it.
Yes you can revert back to 600mhz, but as everyone else has said, do not overclock too far.

Don't overclock beyond what anyone else has had success with. Look up other's successes.
And if you can't, doing it step-by-step, ~100mHz at a time, slowly, will make it feel hot or crash before it explodes (back down if it does get hot or unstable).
Undervolting can also help counteract some of the bad parts of overclocking, without affecting performance at all. UV can, worst case scenario, cause data loss and crashing, never hardware damage, but best case scenario improves battery and device life. Again, do it step-by-step, 5V at a time, slowly, and back up when it starts acting weird
You can check this guide:

you need to have a kernel that allows for OCing/UCing , i'm not sure if galaxy fit allows it
you'll know if it allows it or not if you'll run an app that allows for OCing/UCing, if it doesn't allow it, the maximum frequency at which you can set is 600mhz only which is the default.
My phone's rooted for the first time several days ago and the CPU is overclocked from 1Ghz to 1.7Ghz.
I suppose it depends on overclocking application. The ROM that I have includes an O/C app and there's an option called "on demand" which means even if your CPU is overclocked, it will not utilize the max clock speed all the time.
My phone actually runs at 300Mhz on standby and around 1.2Mhz when I am using it to surf, listen to music or watch a movie. I've never seen it run max 1.7Ghz.

It depends on your device (and kernel), plus the frequency you set it to. Also, it's based on your preference to do it or not.
Hi, i have just flashed the new HyperDroid v5.2.21 (Full wipe) and i wanted to know if i can overclock my SGS2 from 1.2ghz to 1.5ghz, if so how do i go about it?
Do i need to change the current kernel (XWL1)?
P.S ive heard its stable, but does it drain the battery?
Thanks XDA Community
Hello there. Yep you can overclock but you need a kernel that supports it. [url="http://gokhanmoral.com]SiyahKernel[/url] is a good choice. With that, use the Voltage Control app from the market.
However I know nothing about battery draining or stability... dualcore 1.2GHz mobile processor is more than enough for me, and the phone can get pretty hot under maximum load, same with the MALI GPU which can be overclocked to 400MHz (but since it has 4 cores and the phone has no active heatsinks it could get risky...)

Yes you can overclock and you can stick with the kernel that comes with Hyperdroid. I am currently Overclocking 1.6ghz max and 200 min. Not touching voltages though. Use No-Frills app to set it up. My advice though to you no point in overclocking as 1.2ghz is good enough as it is..And the kernel you are on is good enough...It is stable depending what voltage frequencies you use..I say leave it as they are. And like i said download No-Frills from the market..Set your clock speeds and that should be it..Choose a governor and off you go

No-Frills ? AndroidMeda Developers recommend Voltage Control (and I personally like it much more than No-Frills, too) with their kernel.
+ Here is a small guide : http://forum.xda-developers.com/showthread.php?t=1036020 how to test your OC Settings, I use it when I am testing new voltages.
Thanks for the replies i will try out the no-frills app and see what happens. What would you say is the best governor to use? and wouldnt you recommend going over 200min?

Pongster uses No-Frills. The rest of the team uses Voltage Control. And to avoid any freezes or random reboots leave the voltage settings as they are till you get to grips with the overclocking. Hence why i suggested No-Frills as currently Voltage Control for me kept on reverting back to stock frequencies..And yes there is a way round it but it is to much of an effort

I am currently using ondemand and Sio as scheduler. You can not go wrong with that. Like i said..choose a governor choose a scheduler and let them do the work...I also do recommend Voltage control but No-frills is simple and does the job for you. And no i would recommend either go to 100min or stick with 200...I am currently on 1.6max and 200 min

for hardcore gaming, what governor have you found that works the best
for best batter saving, but still be able to watch videos, surf web, email and just general navigating without it being too slow.

Use the smartassV2 governor. It regulates the CPU frequency according to load (sorta like ondemand except it works better).

I'll have v1 of Funky kernel out soon if you want to try out wheatley.
I've been a fan of smartassV2 since the first time I used it on the Thunderbolt. It is as close to an ideal governor as I've ever used. SmartassV2, with a complete sysfs implementation, can be tweaked very nicely. It is a governor that you can really tune so that most of the time it's not running balls out, but it's not loafing along either, which is how a governor SHOULD function. (I like to see a nice bell curve peaking at an ideal frequency, and spiked way out at the bottom frequencies when I look at a bar chart of my time-in-state's.) From what I can tell, few if any devs tune their governors to their kernels. I'm thinking that's how we ended up with a dozen or so governors that are rather similar, yet rarely ideal.

Yeah. Don't use DSB's kernel. I spent DAYS trying to figure out what his kernel is trying to do as far as governors. I'm not going to talk smack about the guy's work, but I will tell you what I know.
I doesn't appear any of the governors have been tweaked for his kernel. It looks like code was just tossed in there and left however someone else wrote it. For instance, smartassV2 has a sleep_wakup_freq of .998GHz, which is much slower than it should be. It SHOULD be near or equal to scaling_max_freq. Likewise, the max_cpu_load (which determines when the cpu should scale up) is 70, a fairly aggressive number, while the awake_ideal_freq and sleep_ideal_freq are pointlessly high. If I had to guess, these look like parameters for a Snapdragon S1 SoC, not the dual core S3 the Rezound has. No matter what governor you choose, it's only active on "cpu0". "cpu1" runs ondemand no matter what. The reason you have trouble making settings for the governor stick is because the sysfs location disappears and reappears for no obvious reason. It appears when things pop in and out (presumably when cpu1 goes on and off line), things are reset.
Cold hard reality is this: You're NEVER going to optimize any kernel out there to it's fullest potential. Either the options aren't there to tweak, or they behave in inexplicable ways. I can't tell you why DSB's kernel (not to single out a dev or his work, but I'm certain that's the kernel you're talking about) does what it does, but it's so far divorced from optimized on such basic levels you're better off not wasting your time.
As an aside:
After getting a rough feel for what some of these kernels are doing, I'm not at all surprised some kernels have had significant heat and battery drain issues. There are things that simply do not work right or work consistently. The devs shouldn't be blamed for this. These are probably the issues they're trying to work around that they inherited from the sources they're starting from and what makes tweaking them so difficult.
I acutely got everything to work. I'm just trying to overclock the GPU.
Hello all
I have a bit of a small problem. I like to run my phone using the Performance Governor but after a while it goes to 1Ghz on all 4 cores despite me running it at 1.8Ghz. Setting it back seems to correct the issue but in time it goes down again.
I believe it is getting a bit warm and thus it hits a limit and the system auto slows to 1Ghz.
Can anyone confirm this behaviour? It never happened to me before but I have had a few kernel updates and updates to the Omega ROM that could be the cause but I am not sure. Is there a setting where I can tell my phone what temps to throttle at?
Also, I assume all this is down to the Kernel and not the ROMs?
Would like some imput regards where to start my search to return my phone to its previous state as a pocket heater.
Many Thanks

1.8Ghz is not healthy for the CPU in the long run and will cause overheating which is exactly what you are currently seeing.
Especially since you keep the phone on 100% CPU power all the time (performance governor) which should drain battery like hell as a side effect.

This is down to your settings. Neither rom nor kernel.
- Don't overclock (much)
-Use a good kernel such as Siyah

Hi buddy and thanks for your response.
I am not sure about what you said regarding it working correctly, it gets the best results for any benchmark compared to others so I would be interested in more detail about the specifics of how its not working correctly as I have never been told that. It would be appreciated.
I dont mind the battery drain although I do heed your warning about about longevity of the CPU.
I have been using Siyah Kernel for some time now and I find undervolting a little unstable, for now I am forced to use pegasusq.
Can you or anyone else answer the original question as I still wish to pursue this to a resolve other than not using it.
Many thanks for your time and efforts non the less!

it´s samsung´s based roms related: when the battery temp hits 41C the cpu will throttle. Nothing related with de cpu temp (can be at 80C before throttles).
try CM10.1 and you´ll see what im talking about.
We need a solution for this throttling with samsung based roms
I have a problem with my m4 Aqua. All my cpu cores Are active when screen is on. I am using on demand cpu governor. Even with the other cpu governors the problem is still there. I have this problem with 3 different stock firmwares.
Is there anyone Who dont have this problem?

Thanks for your answers but i disagree. On my Z1 Compact, it only activates the other cores when i touch the screen, or when it needs the extra juice. Not only because it's on. This results in a huge battery waste wich i don't have on my z1c.

Not true, most of the processors have just only one core activated when you are doing nothing and it turns on more cores when it needs them. This is the first processor I've seen that almost has all the cores turned on all the time.

Is it possible to change that without making a custom kernel?
Sadly, no, i tried to turn mpdecision on using terminal emulator and nothing happened, maybe sony ripped this function at all in kernel
But if you need to save battery and still have a good system response i recommend to set the 4 big cores to powersave governor and let the small cores in interactive, you can set like this using kernel adiutor (is totally compatible with big.LITTLE arch and can manage individually the smalls and big cores)
