when i use 729 or above my Cpu stops working and its Reboot automaticaly any way to fix
Unfortunately you can't fix it. The overclock ability of the cpu is different in each phone. Some x8 can run on 800+ MHz, some can't reach frequencies over 700MHz. Basically the SoC (the cpu, gpu, dsp and some other device) contains millions of transistors, but the whole chip is only ONE small piece of silicium, the transistors made by litographic and other complex (and expensive) procedures. The overclock ability depends on the material quality (damages in the silicium structure), soldering quality between the core and the casing, etc. So, no existing rules to the overclock, if you lucky you can reach high frequencies, if you unlucky you can't overclock.
Note: under the manufacturing procedure the chips get a selection after testing, the highest quality 7x27 chips marked and sold as 7x27T with default 800MHz.
There is an app in the market called No Frills CPU Control: https://play.google.com/store/apps/details?id=it.sineo.android.noFrillsCPU
It will automatically change your CPU frequencies during boot to save your phone from hard bricking.
Anyway CPU gets overheated by overclocking as more amount of power comes in to it than what is required. So as a long term effect your CPU will die out and also your Battery too. So I would say to use a faster rom and dont overclock the CPU to very high frequencies.

You are using stock kernel?
Overclocking more than 729 is not possible for stock kernel...
Use "set CPU" application & remember to uncheck "set on boot "option
# I couldnt over more than 729 in stock kernel but now with nAa kernel in can overclock up to 787 mhz

governer also matters, I always use smartassv2
As someone wise already stated, better using something like FroyoPro which is blazing fast compared to any GB rom instead of overclocking.
I can do more with FroyoPro than anyone running GB, ICS or JB roms.
It's just simple - lighter code takes less cpu cycles therefore it is quicker.
GB, ICS and JB roms really are a waste of time once you've tried FroyoPro.
The other roms are really only good for proof of concept - not for everyday usage.

I tried it , it's not that much good:/ plus it have so many bugs with alfs kernel.(brightness bug for example)
I compared it with iXperia 8s rom before, froyopro is better @ one of 3d tests(just 2 fps better)
Other test were like iXpera & minicm7
Remember it's froyo & they are ginger ,they can run newer apps .
My opinion iXperia is our best rom till now

It also depends on the kernel you are using..Alfs is better in this aspect..but too much overclocking is not recommended.
if you are using custom kernel ,under CPU settings, select the frequencies you desire and do NOT select "Set on boot" . Even if your phone gets rebooted due to overclocking the default values will be applied at boot. This way you can avoid problems.

please read 2nd post by pilu. that's the best explanation. it's a hardware limitation, and it does NOT depend on the kernel.
[cAs]
Partially depends from the kernel too. The cpu clock is not only a simple value: xyz mhz. In the kernel this is a little bit complicated (pll frequencies, dividers, multipliers, voltage level, etc). Different kernels use different frequency tables, the results can be different, this the developer choice who can set different bus speeds (axi, ahb), base pll, voltage to every clock speed. You only see the frequencies in the different kernels, what is same, but the same speed maybe generated with different method.
So, the cpu overclock ability is 90% hardware limitation and 10% other things. Usually if you reach your own max speed with a kernel, the probability of higher speed with another kernel is small, the typical difference is nothing more than +/- 1 multiplier (+/- 19,2 mhz).

I have a question: why I can't overclock my SGS past 1.2 ghz. When I try to set for example 1.3 or 1.4 it freezes and I take out the battery in order to make it work again. Is there something I do wrong, is it a general problem with more SGSs? If somebody can , I really appreciate. Thanks
it is a kernel thing.
the kernel has to support those frequencies.
Sent from my GT-I9000 using XDA Premium App
I tried with tegrak overclocking with voodoo kernel (the application itself doesn't need a kernal that supports those frequencies) and with Supe Optimized Kernel (1.4 ghz) and voltage control and setcpu and is the same result:freezing.
Not every cpu is capable of stable overclocking past a certain threshold. You have probably hit the max speed your cpu can maintain.
I agree with you but then why there are other people with the same phone as me that can overclock them at 1.4 ghz?
With CM7 or miui and either bilboa or zacharius kernel you can overclock to 1300 but I haven't found a kernel that allows 1400 either, I think those that are doing it are hacking the CPU settings themselves.
My phone gets really hot at 1300 running apps like dungeon defender so 1400 might just be a bit too much

can someone shed some light?
I've seen someone test this on another forum somewhere, and the difference the undervolting makes to the battery length is negligible..

The principles of ovetclocking a PC also aplly to phones. Undervolting reduces the power available to the CPU. Undervolt a little and you'll save a little power. Undervolt.too much and the CPU won't get enough power to do basic functions hence freezing.
Every CPU has a limit to which you can over clock. You can overvolt to a point but then then the CPU reaches its limit.
From what I understand (read in another post) the hummingbird processors are not suited to overclocking. Where the arm such as that in the Motorola milestone clock really well. (You can oc a 600mhz milestone to 1ghz before you start seeing instability)
Hope this helped.

i always use 729-748 as max cpu frequency and the lowest frequency as min cpu frequency... as governor i use ondemand or lilgV2... for me works fine but you should find your own configuration because it depends from the use you mean to do with your device... for example if you use you phon for gaming so you need high freqency for lagless gaming experience but a governor and a shleuder that make long battery life... try by yourself xD
For maximum freq 710, for minimum freq 245 (less chance of hanging when waking device) and governor smartassv2. That's how I roll

Download Semaphore Manager from the market. You can overclock using that app. Mind you, semaphore kernel can get glitchy at ~114% OC and up, so you might want to go with 110 and build gradually until you find a sweet spot...

the "live oc" has better performance of "simple oc" (at equal overclocking), because "live oc" overclock all frequencies and not only the higher frequency.
But with "live oc" you can raise less the frequencies

Theoretically yes, but if you overclock BUS, your CPU, GPU, and RAM are OC'ed. On stock BUS is clocked at 200mHz. If you use LiveOC 110%, you overclock everything by 10% - GPU goes from 200mHz -> 220mHz, CPU from 1000mHz -> 1100mHz. That's why it's more unstable than normal OC.

You might be able to get a higher stable overclock with voltage increase; available in later versions of semaphore, but that's something you'd need some guidance doing, and of course there are the general risks of that.

Hello, Im new in Note, installed yesterday Slim Bean Rom and hydracorenirvana v7 OC kernel and I noticed that Note get warm, like 35-50 C while browsing internet or doing some low requerements stuff. I tried to low CPU to 1ghz but still the same... And while playing it jumps more then 50C, is that normal? I really dont want to burn it
Probably the media scanner is maxing the CPU, normal after installing a new ROM especially if you have a lot of files. Give it some time to settle down.

Dont forget the Hydracore is a maxed out performance kernel, designed for ultimate speed, so it will generate more heat doing basic things unlike the stock kernel.
and not to mention the massive power hungry screen and huge battery inside, its normal so dont worry about it. If it gets to the point where its too hot to touch, just remove the battery for 10mins and allow it to cool down.
Can I OC and UV GPU with hydracore kernel? I have S2 with dorimanx kernel , there is Stweaks app its very usefull when I can choose battery or performance profiles. and its auto OC and UV on that kernel. Can we get something on Note?
there are many apps that can do this, Tegrak, SetCPU etc, but be careful messing with voltages as it can prevent the phone from functioning.
You can use a basic app such as no-frills-CPU to adjust OC and governors.

If you use a custom kernel like iodak or ww, you can tweak many parameters. Among them there is cpu clock frequency and voltage.
Personally, I've set the stock 1500 mhz frequency and undervolted Mpu and cpu respectively by -30 and -75 mV. My phone runs smooth as silk and never gets horribly hot.
The guys who replied before me are right, though, stock roms or their derivates cannot be compared with CM11 in terms of performance they are way better. If I were you, I would flash one of the latest nightly and a custom kernel.
After some trials and errors you will be able to find the correct balance between over/underclocking and undervolting.
That is, if you are willing of doing some experiments. If you are looking for pre-cooked solutions I am afraid you will be deceived.

Trickstermod is a favorite for most of the people.Check your tegra variant, if it's 1 or above, you can use -122mV for CPU with no problems, max freq set to 1.5 ghz
I'm using this for months now and I sometimes forget my phone can get hot, unless I do heavy gaming for 30 mins or more.
Also try to overclock GPU.Helps a lot with FPS issues.
If you want good battery life and decent performance, underclock to 1300 mhz and undervolt by -122mV (if your variant is 1 or above)
Btw you can check your variant via /sys/devices/system/cpu/cpu0/cpufreq/tegravariant after installing iodak kernel.Higher the variant, the higher you can overclock/undervolt.
@UP
My tegra variant is 3 o.o But when I undervolt 30mV on CPU and 75mV on MPU - as @peppethustra recommend in http://forum.xda-developers.com/showthread.php?t=2761923&page=2 - it causes freezes, even when I underclock to 1,3GHz :/

All phones are different you may have to tweak the values to fit your needs. Try upping the LP CPU voltage to -10 and work your way down. For MPU try -25 and work your way down on that as well.
Mine is a variant 2 and can use -20 and -110 with the 520 GPU overclock
Edit: also for more performance try changing your minfree values. Lower values mean better multitasking and high values mean more killing of background apps but more free ram for the foreground apps. I personally use 8, 12, 45, 65, 95, 165
