If your motherboard got burnt by overclocking, your phone is bricked.
thank's
if i set cpu Frequency to 900 Mhz haven't problem for my phone

NO problem. The best CPU frequency is either 864mHz or 883 mHz. Up to you!
No kernels we have will do that I'm pretty sure because we haven't entered the wonderful world of voltage changes. Just keep the bat temp under 50 degrees

Which software shows the CPU temperature
Ah its maybe brick some phones
But its power off immadietly when got high temperature
Sent from my GT-S5830 using xda premium
Overclocking too much like more than 900 Mhz may get your phone in high temperature. Also continuous overclocking can reduce your processor's remaining life span. So if you're planning to use your phone for long time. I'd suggest to not to.
PS:
1) I have overclocked to 864Mhz for normal use (Using SetCPU), Priority: 50%
2) To stay away from heating, given max Clock to 640Mhz when Temperature is >39%, Priority: 75%
and there are some other profiles too but irrelevant to this topic.

First, you crack the bootloader.
When you've done that, I'm guessing you allready figured out how to OC the CPU

For now just use the overclock widget. set top two settings as high as you want up to 998 click on off screen frequency. set between 246 and next number you choose. set at boot save. define settings at what mhz you like and experiment. do not run on screen and off screen freq at max. i have had my battery sweating and even plugged in all day and not gained a single % of charge. until boot loader is cracked.... this is all you can do.

Although it's impossible today because of bootloader, note it's always dangerous and not great to overclock embedded cpus.
You can't overclock a lot, as you have a battery (X10 works about 5-10 hours with full speed - 998MHz), and the CPU only has passive elements to cool. Overclock can damage your CPU and your motherboard, stress all elements and low your battery life (battery charge and cycle of charge). (Even there's a self shutdown when too hot)
You can get an idea of overclock on Nexus forum, as we have the same CPU (Snapdragon 8250) - I saw overclock up to 1300 MHz, but it's really not looking safe to me
Thanx everyone..

Depends also on the voltage (as long as your voltage isn't increasing as you overclock, it isn't really that harmful as long as you watch the heat), and what you have your underclock speed set to with screen off (as this can in some sense reverse some of the possible "damage")...
I had my htc hero overclocked to 710 with the screen on, and underclocked 176 with the screen off and it ran a lot better.
I digress, I see no purpose in doing so when you already have a 1ghz processor that is super fast. I only really see a point in overclocking if the possible benefit is greater than the possible harm, and in this circumstance, I really don't think you would see that much benefit.

I have seen considearable difference when maxed out. however the dangers are high of overheat. ive done it once and onetime only. kept on and off screen at 998 and hat it plugged in all day with out a single gain of battery. it was like on life support and was hot enough the phone was sweating even when sitting next to a fan blowing on it constantly.:-( since then i have made adjustments to run between 700 and 998mhz on screen and min 246 and 400mhz when screen off.
if looking for better performance without the overclock and good drain of battery, download and install sysctl from market and follow settings below.

Not in all instances. Depends on the quality of the chip. Lot of chips are capable of handling higher speeds and temps but are set lower quality assurance.
For instance, I've got a NookColor that has base CPU set at 800MHz and is now overclockable to 1.2GHz
We'll have to do stress tests on some to see what they're capable of.

Agreed.
My Motorola Defy has a Omap3630 that comes at 800MHz,stock but can be easily overclocked to 1.3GHz without a sweat.
Just depends on the chip's capacity of "Stress".
Respect
1st : My understands
So I'm completely new on the undevolting science and don't know if I understood everything correctly... For me, undevolting the cpu means : reduce power consumption for the same speed, so we can minimize the battery drain and have the same performance at high frequencies. Am I right?
I also understood that if we UV too much, the phone will be buggy/freeze. Is there any other risk I should be aware?
2nd : My statements
I start to UV my phone tonight and now I'm quite surprised to see how low I can go : I'm running at 1200MHz / 600mV (instead of the stock 1275mV) and the phone is solid stable (I don't know if I can go slower though, I was a bit scared and decided to post this message before continuing). So how do I check setcpu applied the settings correctly? To check system stability I use setcpu's stress test for about 2mins (the short test between two settings), then about 10mins (the big test for the final seting) and finally my feelings using my phone as a daily usage. Am I doing it right?
What are the common values at the UV exercise?
3rd : Some wtf in my head
If our phones can handle a so low value (compared to the stock one), why is it so high by default? I understand that, for stability and because every device is different, sammsung could not use the lowest value, but even some 100mV could improve the battery life of the phone, and since not everybody is tweaking his phone as us, it would have made an even greater phone OTB...
PS : my configuration
Phone/Pda/CSC : XXKG5
Kernel : ninphetamine 2.0.5
Yes, lower voltage is better but not all chips will take it. With undevolting the main risk is random instability or reboots, if you get a reboot just scale your uv back by 25mv and see what happens.
As far as why the voltages are what they are, for a chip as young as the one in the sgs2 there is a lot of variance in the chip, not all will be as "good" as others, so samsung bin (select) them to hit the clock they do at the voltage they do at a certain yield (aka not to many chips unable to hit the needed specs).
Maybe in the future the stock voltage will be lower, but for the time being we can tweak and see if we got a gold sample (better than standard) chip.
Also as far as your uv settings, you are not at 600 or something mv, the kernel has a hard lower limit of 800mv, even if it slows something below that in setcpu, the minimum the kernel will give the cpu is 800mv.

Thank you very much for your quick reply ! And sory for being late too ^^
I indeed re-read more carefully Ninpo's thread and saw his kernel can UV from 800mV to 1500mV. Btw I think because 600mV was under the limit, stock setting was applied.
So after a day of testing, I can say my phone handle 200MHz / 825mV, 500MHz / 850mV, 800MHZ / 950mV, 1GHz / 1075mV and 1,2GHz / 1150mV with no problem at all And now, my battery will last forever

To make it last forever you want to set it to 0mV
Just don't set 200mhz to low or your phone may suffer from the sleep of death where it won't wake up.

What are the best settings to have you phone's CPU speed set at? I'm looking for both good performance and good battery. Also I am using the default overclocker, what is the best one? Thank you guys for your time.

I use SMARTASS as my CPU speed governor and I set my CPU to 480-748 MHz, seems pretty stable for me.

Overclocking values differ from phone to phone. Test it out with different values and use the one which is stable for you.
This was just discussed in the IHO technical-discussion thread, as a matter of fact.
My phone is stable for most stuff at 806 MHz, but sometimes the camera will cause a freeze/reboot. So I run at a 786 MHz max. Your phone will be different; this has to do with minute physical differences between individual chips.
The thing to keep in mind when overclocking is that the processor in our phone (unlike those of many other phones) does not make use of dynamic voltage scaling. There are only two voltage levels: a lower one if the phone is running at or below (or is it just below? correct me if I'm wrong, guys) 480 MHz, and a higher one if the phone is running above. So below 480 MHz, the system will give the processor a certain amount of voltage (period), and above, the processor will get a certain higher amount of voltage (period).
Because of that, the tests that have been done indicate that 806 MHz is the sweet spot for battery efficiency when the phone is in use--and the closer you get to 806, the better. Thus, I've had the following settings for quite some time:
786 MHz min
786 MHz max
Performance governor
which has treated me pretty well. On a day of light to moderate use, I'd end up with 65-75% battery left (occasionally more like 80%), depending on cell signal where I am et al. And it gives me probably the best performance I'm gonna get out of this phone.
However, I very recently decided to change the minimum to below that 480 MHz threshold and see what a lower voltage when idling would do for my battery life. My current settings are:
320 MHz min (may change to 480)
786 MHz max
Smart*** governor
There is actually a noticeable performance decrease when I first wake the phone up, so I may switch governors as well. In any case, I've had those settings for only one full day now, but for that one day the battery life was noticeably better. I'll post an update when I've had a few more days to test.
As always, it's difficult to quantify battery life in a reliable/rigorous manner (much less a universally applicable one), so YMMV.

It is not a static value across devices. Test it out yourself and use the one which is stable for you. Some guys have it stable even at 806 while my phone freezes at anything above 768.

My o1 freezes at abt 800Mhz...
If you want to play safe, keep it under 720... after this it starts becoming unstable....
Press Thanks If I helped...
i would not set anything more than 768
and i like to set it one level below the max I think I can go.
so i set it at 480/748, and it is stable
varies...im pretty stable at 480/844
Depends on your Hardware
Try frequencies from 729 to 806 , but remember to uncheck the "Set on boot" option. (Just in-case to avoid boot loops)
I've set mine at 787
Thanks guys! I will try!

What about the lower end of the freq?
I see some people cost 245 while some post 480.
I'm thinking 245 give it a better battery life since its lower but I've also read somewhere that 245 is too low and it causes the cpu to ramp up and down.
My phone gradually increases the chance of receiving a kernel panic starting at 768 MHz.

I've been reading a lot about battery saving in our P500 and it seems that power consumption is the same for frequencies of 480 mhz and below, so in the end, the phone sleeping at 245 consumes the same battery as when it's sleeping at 480.
With that in mind, it's much more convenient to set the clock at 480 mhz at it's minimun since it provides a better response and wakes the phone faster, ending up in less processing time with same battery consumption.

That's not 100% correct. if you download an app like CPU Spy you can monitor how much time your phone spends on each CPU state. unless you do a lot of gaming and other CPU intensive activity your phone will spend most of it's time in lower CPU states. unless you specify that you want it to run at 1113 MHz at all times which yeah, would kill your battery faster. just looking at CPU Spy on my phone OC'd to 1228 MHz it has spent 70 hours in Deep sleep and 25 hours on 245 MHz. only 3 hours at 1228 MHz.
So unless you do CPU intensive things on your phone you shouldn't notice an overly dramatic change in battery life.
