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~~
call me a noob but i gotta ask, just what does the kernals do to the phone thats so special, and all the ghz talk means what. i rooted my device for the teather and customizing, and now i see all this talk of kernal this, overclock that, and different ghz people are getting can someone explain to me what this does for your phone, should i be interested???
popcorn kernals?
the higher your ghz the faster your phone is.
overclocking is making your ghz higher
and kernals is what allows you to overclock(sorta)
lol dude...you should prob. take your time with customization but ghz is in reference to the speed of the processor. So...theoretically the higher the number the better your phone should perform...t, eoretically lol. Note that with a higher ghz value the worse your battery life will be unless the kernel is written really well. Also the kernel is the code that controls the devices hardware. (brain)
The nice thing is that you can generally play with different kernels without having to wipe and redo your phone. Also, if you really want to play with the various kernels out there you should get setcpu from the market. It let's you set your phone to make use of the processor in an over clocked (OC) application but it can also let you under clock your phone when your not using it, such as when the screen is off. This will help you conserve battery life. But be careful, over clocking can lead to over heating and other problems if you''re not careful
sounds very interesting, hmmm. so in the coming months people could create kernals to acheive speeds to challenge dual core phones
the kernels already are challenging dual core phones. The thunderbolt currently has a 2ghz kernel. The motorola atrix is a 1 ghz dual core... Thunderbolt definately rivals it with overclock kernel

A "kernel" is the OS layer that sits between the applications and hardware. So, when an application says "light up LED" it eventually goes through the kernel to do this, most likely by a request/system call.
The speed of a CPU is measured in hertz (frequency). So, a 1 Ghz CPU can perform over 1 billion operations in one second. The frequency can be increased (overclocked). When you do so, this can damage the CPU (most likely due to heat). Heat can also cause the CPU to run efficiently. So, if you overclock too high, you COULD end up running slower than if you had just left it at 1 Ghz. Changing the frequency can also hinder stability.
so with it being so dangerous how do u know what kernal to trust and whats a safe limit in hertz, do u stop at 1.5, because 2ghz sounds like pushing it
This thread is so full of misinformation it is comical. To start, higher clock speed does not always result in better performance.
Secondly, everyone has their own preference. The best bet is to find the perfect balance for your needs. For many people, overclocking the CPU is not very beneficial... since the device is already plenty fast at stock 1GHz speeds. A lot of users would rather use custom kernels to make their device more power efficient and use SMARTASS governors and lower voltages.
Mess around with kernels and see what you like the best! (always remember to create a backup before flashing... this allows you to easily revert back if something goes awry).
You mean they're not popcorn kernels?? Lol

+1 ninja point for correctly saying "over 1 billion"

It should be noted that most phones are definitely capable of being overclocked to a reasonable extent.
the majority of kernels we nexus one users play with, is undervolting the and playing with teh voltage tables to maximize standby battery life, at the same time overclocking the high end to improve performance. but really its about lowering voltage to improve battery life.
Hi im thinking of doing a overclock to 1.5 ghz is it safe for the processor and the battery life witch already sucks. has anyone on here whos done it using setcpu and the rom had any problems after doing so ? and how much faster is 1.5 ghz compared to 1.2 ghz on the galaxy s2 ? and is it safe in general for the hardware of the phone will the phone get hotter or have over heating problems ? also what should my settings be for minimum maximum and the voltages ?
Of course oc is going to make ur battery life a lot worse.

I haven' used Setcpu in a while but I believe it's got a feature to stress test the settings to see if it can handle it. Generally the worst that happens is it'll crash. So long as it doesn't get hot. Heat=death for electronics :')
I'm using tegrak (from market) to overclock to 1.4. I found 1.5 was too unstable. Noticeable difference between 1.2 & 1.4 is almost none. Also voltage increase of 50mv was needed to gain stability. There is not much point of overclocking the device IMO unless like me u just get some satisfaction out of knowing its running faster!

This is true. I see no difference between 1.2 & 1.5ghz. But that doesn't keep me from running it at 1.5 when I'm playing a game anyway :'D

Well it's not safe, that I can say. Nothing is safe when you don't know what other things are changing with the clock rate. But still you could do that. You just have to make sure that the temperature is within limit, it will be definitely high, but make sure it's not that high.
And upping the clock rate to 1.5 GHz won't drain any extra battery than 1.2 GHz.
Regards.

I tried the overclocking and each phone is different, increase then test, there are many benchmarking apps out there, I was stable at 1.4, my kernel does not include 1.5 GHz, and irregardless of what people may say, running the phone at higher clock speeds consistently DOES drain the battery more than 1.2GHz, unless you have found a way to manipulate the laws of physics. I don't see how one can fathom the thought that you can get a faster CPU at absolutely no cost.
Many people think when the CPU running faster means you complete tasks faster, hence 1.5 would complete a task faster than 1.2 and hence save battery, but I believe we use this phone as more than a calculator, so when you are performing a task that causes the CPU to run at 1.5 for a period of time e.g playing a game, browsing or whatever you do with your phone, then the CPU has to draw more power to keep the frequency at 1.5 as compared to the CPU running at 1.2
All in all, I dialed back because I was doing fine without it and I did not need it, other people may need it, and I wasn't gaining anything. to answer your question directly, it all depends on what you do with your phone, I'm not a huge gamer or anything and the 1.2GHz has proven to be more than enough for me to have a very pleasant experience using this device
Using it occasionally is safe, unless you stress your mobile at 1.5+ ghz for more than an hour or so.
The cpu governor will only make use of higher frequencies when there is a need, so mostly you will see your mobile idling at 200 mhz.

Not necessarily a lot worse. It depends on how you are using your phone, and what is causing it to run fast. If overclocking allows the phone to spend longer in deep sleep state, your battery will win. If its games, and by OC you achieve a higher frame rate, then the phone is doing more work, and this will be reflected in the battery life going down.
Most of the time, screen on is going to dominate. If you are a low screen-on user, I guess there is more chance for a higher max_cpu to be beneficial (it won't be used unless there is a task that requires it). More accurately, it helps some of the time, so the net result is not always obvious to predict.
How about undervolting?
Any danger in doing so- other than crashing when voltage is too low?
Before over clocking it might be worth downloading cpuspy from the market and seeing what time you spend in each speed.
Chances are most of the time you won't even hit 1.2 so might not have anything to gain by over clocking.
Then again I dont know how you use your device but I do know I was surprised when I found out.

I've played with the SuperSonic version of this phone (which has a 1.5Ghz core) and the results from photos/video are much better, I'm pretty sure the cameras are exactly the same but the SuperSonic benefits from the higher CPU.
I think it would be cool if somebody could write an app that states
IF user opens Camera application voltage + clock speed is increased to allow stable 1.5GHz speed
WHEN user closes camera application overclock turns off.
Thoughts?
You have a smartphone! Not a pc!
I didnt see any advantage if you oc to 1.5
Btw In normal use your phone keep in 200mhz not 1.2.
I think i only hit 1.2 two or 3 times for 3 seconds in a full battery cycle.
Sent from my GT-I9100 using xda premium
oc dosnt make sense ,there no noticeable diff,an yes very few times i hit 1.2 mostly its on 800 or few times on 1000....using a device with 1.5ghz proccesor an oc a device to 1.5 ghz which has 1ghz processor is very diff in nature....
Fair enough.
Well I wouldn't mind an app that mazes out at 1.2GHz with camera app open, as it can lag when shooting HD.
oc upto 1.4 ghz is fair enough, anything more than that is a waste. though you cant find any visible difference between 1,1.2 and 1.4 it does helps in maintaining smoothness on some situations.
yes very true i had oc my sgs1 at 1.2ghz and sgs2 at 1.4ghz but frankly i dint see the diff so after few days use i turnd to orignal settings....but many use oc an phone works fine,but depends on personel use......an yes as bala_gammer says its fine on 1.4ghz......cheeeerz

Plz help @..Longtime hd gaming(gta sa,nfs mw , asphalt,modern combat...) using 1.4 ghz is safe?
I also noted that gameloft games are makes more over heat for phone..
Which is the best and safe voltage level for 1.4 ghz 1250mv or 1275mv or 1300mv

after root... i have installed SetCpu, i have overclock my processor to 1.6ghz.. the question is, can i use this setting for daily use? is it will cause my processor hot or damage??
Depends on the phone. Mine can't run above 1.4ghz stable (but my GPU can overclock easily).
^What he said. Try it for a while, but if you get reboots or freezes, pull it back to 1.4 or 1.2.
if it runs stable then you can no problem
Watch your temp. Might be a phone but it's the same as a computer. That reno gets to high, and you're looking at overheating and possibly causing corrupted files from shut downs or worse, hardware damage.
Correct me of I'm wrong.

Just make sure you don't check "Set at boot" until you're sure you can set it at 1.6 with out reboots and crashes...... GL
Why 1.6ghz all the time? 1.4ghz uses MUCH less power (meaning less heat as well) and is 99% as smooth.

Very good point....
I underclock to 800 . And phone is just as snappy. Why would ya wanna use 1.6 out of curiosity ?
Sent from my SGH-I777 using Tapatalk 2
Honestly the only reason someone would overclock to 1.6 GHz would be for bench marking, which i find useless. My processor is usually clocked to 800 MHz and i can play games like N.O.V.A. 3 with only slight lags here and there.
I do something similar to a few people here. I keep it at 800 most of the time and bump it up to 1000 when I'm playing certain games. Then back to 800 when I'm done. Responsive enough for whatever I have to do and doesn't overheat.
Wow OP
What a question OP.
I can't believe no one called you out yet.. I will be the first
If you want to kill your phone hardware then keep it at 1600! (which is overclocked too you dummie)
USE SetCPU so that your phone can
1. remain cool when high CPU cycles are needed
2. save battery by making profiles especially for when your phone screen is off

ok theres good guides out there. just google it
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.
