Hello,
I installed cyanogenmod a few months ago and want to overclock now. Anybody who knows if it is dangerous? Is it possible that your cpu breaks down faster because of the overclocking? which are the acceptable cpu settings?
thanks

It's not that dangerous, but your cpu will wear out faster than normal, because a highter clockspeed means more heat. Acceptable cpu-settings? Depends... most phones seem to handle 691 without problems, anything above that is luck of the draw.
Set your desired cpu-settings (don't use set-on-boot)
If the setting is higher than your cpu can handle you will start experiencing crashes. If you have found a stable frequency for your phone, you can set it on boot so you don't have to think about that every time you restart your phone. If you set an unstable frequency and use set-on-boot, you will get a bootloop.

So the higher the frequency, the faster the cpu will wear out, just because of the heat. I will keep an eye on that.

When playing high-end games, I always put the cpu-clockspeed to 729 mhz...

I tried asking this in the Megatron-thread but as usual, no answers...
I am a little worried about keeping my phone overclocked at all times, so I was thinking about downloading SetCPU and switching between 600 and 700 via that app. But my question is this: Megatron ROM overclocks the phone by default. If I download a 3rd-party app to overclock/underclock the phone, will this mess up the whole system?
Anyone? Would really appreciate help!
i've been using megatron & setcpu together for the past month.. no issues yet, so cant promise ma phone wont go up in flames i clock extra if needed
Ok, thanks!
My Experience: USing LOL rom with default OC gave me kernel panics ...so instead i disabled OC in ROm and wud then OC using SetCPu...ALso I dont know why but touch feels a lot more smoother on LOL rom with the lag fix than megatron....so i switched from megatron to LOL...Currently even with maxCPu 480Mhz and conservative profile..touch is very smooth on LOL

How do I disable the OC in Megatron? By adding the "minitron" file and then using SetCPU?
Hi all,
I'm a newbie in Android world. Successfully flashed my O1 to Megatron v1. Afterwhich I tried installing SetCPU to it and overclock to 806mhz & above. However, after overclocking with SetCPU, the whole phone's performance became more sluggish than the original Megatron 729mhz...
Someone please advise me on how to overcome this and make the phone speedier with high frequency.
Is there a way to edit some of Megatron's kernel to make it 806mhz on default even without using SetCPU?
Don't use set on boot feature, it will make ur phone get stock on bootloop...
So can someone tell me how to proceed with this? I want to be able to change between 600 and 700, when I please. Thanks

Got it! Tried last night without set on boot feature. Working fine with 806mhz and speedier than 729mhz. However my chipset refuses to go into higher frequency without freezing and rebooting... Is it due to my microsd card? I'm still using the original 2gb microsd card tt came together with the O1... Will changing to a class 6 or higher microsd card let me clock higher? or my chipset is just lemon at 806mhz?

FnH84: I downloaded SetCPU from XDA forum and can tweak the frequency between 600 & 700 by myself. Even can set profiles to govern the speed at different situations.

You are already pushing the CPU to its limit with that 806 MHz frequency. Do you even realize is 34% above the designed specs for this CPU? You're already lucky enough you got it stable at 806, and no SD card will ever make a difference, they're not related.
How come Samsung Galaxy Mini running on the same chipset offer 800Mhz as stock???
Man, I don't know! How come the same "Pentium IV" processor could come in speeds from 1.3 GHz to 3.8 GHz?
Can any of you actually believe that LG would underclock an 800 MHz CPU and sell it to us as a 600 MHz instead of letting it run at its best?
Galaxy Mini is obviously using a CPU designed to run at 800 MHz, even though it bears the same name. And that one can probably be overclocked to above 1 GHz.

Thanks for your reply. I was thinking bout the same as the other guy, that galaxy ace can run at 800mhz, and why not O1.
Hmm... Isn't there any other ways to push the frequency higher? Maybe supply more voltage to the core? I dont mind sacrificing batt life, I just wanna try ways to push it to the max~~
Hi... I have rooted my Samsung GS2 and payed for the OC app TEGRAK ..
But every time I go over 1400mhz the phone gets very unstable.
It even feezes at 1400 mhz when i use my navigon app...
I have tested it at 1500 mhz.. But reboots in a kind of save mode.,,,
At 1400mhz i runs Quadrant smooth with 4200 in score
And 56 MFLOPS in Linpack
But why is my phone so unstalbe?

Because it's supposed to run at 1.2Ghz.
If every SGS2 was able to run at 1.4Ghz without any issue I guess Samsung would have set them at 1.4Ghz by default (since battery life is obviously the least of their concerns ^^). When CPUs are produced, there's always variations in quality. what usually happens on x86 CPUs is that they're tested, sorted according to their max stable frequency, and then sold under different names and at different prices. For Exynos my guess is that any CPU that fails to pass the 1.2Ghz bar is just ditched, and they keep the others, some of which will work at 1.4Ghz, whereas some won't.
Now if you want to gain more stability, you can always try to increase the voltage, it usually gets more stable as voltage increases, but it also gets hotter (which can cause it to crash, or may even permanently damage the processor).

At 1.4ghz the phone will also get hotter and it decreases the lifetime if you run 24/7 at 1.4ghz
Ok.. I know about the x86 cpu's.. But didn't think it was the same in ARM cpu's-
But I see ALOT SGS2 that runs 1800mhz..
I guess that I just have one of the not so OC lilkes...
Overclocking won't always work for everyone at same levels.
I've also seen evidence to suggest that OCing significantly reduces the life of the SGS2. Nobnut had his phone vastly overheating even on stock speeds, and constantly rebooting... He overclocked. A number of others reported similar.
Overclocking is not simple and it is not that you just click on 1400/1500 MHz and you are Overclocked. A lot of things matter here. When we overclock in our Desktops then we have to test it very thoroughly, setting up the right VCore, Bus voltage, Multiplier, checking the stability and temperature etc. etc. Tegrak OC is a nice and simple software to use, but it can't be perfect when you can't set all the settings manually other that just higher the clock rate. Personally I'd always stay with stock speed as incorrect OC could harm my CPU and GPU.
Regards.
If you know anything about overclocking then you'll understand that there are a variety of factors that affect the overclocking of a system. The overclock headroom you get from a processor varies, add to that the variables in component tolerance in the circuit board and you have a huge variety of factors that can limit the maximum frequency that you can overclock your system to.
I'll give you an example using my computers. Click on the images below:
Both processor overclock similarly on using the same components and that was the maximum I could get out of them. Now when I bought an EVGA X58 Classified motherboard and overclocked the Xeon W3520 I got it up to 4704 MHz with less vCore and less CPU VTT. All of this was done with aircooling.
My point is that not all systems will overclock the same even though they share the same model components.
Hello, I have an HTC thunderbolt, rooted with CM7, and installed setcpu and used autodetect and I put the CPU govern to "conservative" with minimum GHz 245 and maximum 1.8GHz and I am just wondering if this is safe? because I read some threads about Compatible kernels and I jave no idea what that means, they were also talkimg about undervolting, which agaim I do not know means, anyways thanks for reading

If your device will run reliably at 1.8GHz, then there's not much to worry about as long as the voltage isn't too high. High voltages and heat can shorten the SoC's life or kill it altogether. Generally, I don't recommend running that fast because the performance increase isn't as great from 1.6GHz to 1.8GHz as it is from 1.41GHz to 1.6GHz. These cores weren't meant to run any faster than 1.5GHz really, and anything past that doesn't increase the performance as much as the numbers might suggest.
Also, a conservative governor probably isn't ideal if you're willing to run a device that fast. That governor would seldom, if ever, use that kind of speed. I'd suggest smartass, smartassV2, ondemand, or interactive if you're looking to see a good boost in performance.
If you're looking for an app to view and adjust voltages, IncrediControl works well. For all the nitty-gritty of overclocking, I'd recommend reading my OC guide. It's in the "Second Post" of my Q&A thread. If you've got any questions, feel free to hit me up.
So does over clocking just speed things up? What are the real benefits

I look at it like this. My screen eats up most of my battery. The less time it's on, the better. Overclocking uses more power for the CPU, but the display spends less time telling you it's waiting. It doesn't really add functionality, just speed and efficiency.
Hello,
I'm writing this thread to know which processor options would be optimal in our minis. The best settings, which give me the best performance/battery, I've found are:
CPU Governor: SMARTASSV2 (Default)
Min Freq: 19MHz
Max Freq: 748MHz
Undervolt: TRUE
I'm also using Apex Launcher. Which settings are you using?
Note: This are just my results, be careful when you change your processor settings.

Whats the purpose of Undervolting when you have it's max frequency as overclock?

Because it undervolts on every frequency below 600, and his minimum is 19, so when the phone is idle or doesn't need all of the processing power he saves battery
The SmartAss governor is very good at picking the right frequencies for any given job, so it doesn't allways run on 748Mhz, not even when you're using the phone.

That is the same very purpose of SMARTASSV2 to undervolt your device when idle or on sleepmode and overclocks it when on process. So ticking the undervolt wont affect your device because the one that manage the frequency will be the COUgovernor.

The SmartAss Governor only governs the frequencies, not the voltage that the Processor uses. there is a difference between the speed the cpu runs on (Mhz) and the amount of Electricity (Volts) it gets fed
Say Qualcomm has said it needs 5 volts to run at the stock frequency of 600Mhz, then the processor will always get 5 Volts, no matter which frequency it uses.
Undervolting will feed it less than the 5Volts when the frequencies are lower, SmartAss won't do that, it will run the 19Mhz still on 5Volts.
(Voltages are examples, i don't know the exact values, but I know that running on 122 or less will be stable on less than half of the nominal power)

de-noobing is good from time to time
xda is overcrowded of false answers given by people thinking they know but don't
anywhere, at anytime, newbies asking get fake answers from people wanting to help but failing to do so , due to lack of knowledge.
as everyone, i might be one of these, but try not to be.
make sure you know what you are talking about before spreading your (incomplete or false) knowledge

Hey, thanks a lot for all the replies. I had no idea why my settings worked like i wanted.
I have a super old galaxy nexus that im currently using because i was flashing new rom on my note 3 and killed it.
So i decided to flash franco kernel in this baby to make this underdog fly with 1.8ghz.
The stock is 1.2ghz.
What i did was i set min freq=1.8 max freq=1.8.
Did some stress test, didnt have issues (no reboot or shutdown). But the frequency will drop go 192mhz to 384mhz.
Everytime i stress the phone (games or heavy multitasking), the phone would simply downclock itself even though i DEMAND and LOCKED the frequency to 1.8ghz.
Any ideas? I assume its thermal throttling
If so, how can i get around it? I just want maximum amount of performance
Thanks guys.

Even if i dont overclock the phone, the galaxy nexus would downclock itself from its 1.2 ghz down to somewhere around 500mhz anyways.
Seems to be aging because literally anything i throw at it, it will overheat regardless.
I just want a usable phone, if its constantly clocked at 500mhz, its literally slow enough for me to certify its a piece of garbage
