I've Tried a lot of rom, kernel, too much time spent on this phone to see that ondemand governor, interactive or conservative doesn't stop frequencies of Tegra 3, I see through CPU Spy that, even I stop max clock to X mhz, it goes 1.4 ghz, 1.5 ghz...
There is a kernel that work? A rom that work without this problem? This is a bad culprit for the poor battery of this phone...

If i overclock but only when need more perform power whats the adverge life i ll get out my phone?
First of all how much do you want to overclock: 1,1-2,0 ghz ?
If you overclock to 2 ghz ( if you're phone is stable ) you will be sure you get a huge drain in lifetime. I have my phone overclocked to 1.4 ghz as I think this frequency doesn't harm your phone.
Second is not all the cpu's are the same, for me every frequency is stable, but maybe youre phone is only stable up to 1,4 ghz ( for example ). So keep that in mind.
The fact is you can't exactly say how long youre phone will last at what frequency as every phone's cpu is different. But I suggest, don't go over 1,5-1,6 ghz as you won't get any noticeable performance boost after that and at higher frequencies it does harm your phone.
So make a profile in "setxperia" and call it power or something you like, set it to 1,4 ghz max and threshold to 99 governor ondemand. This works the best for me, and if you don't need the power ( not gaming ) then switch it back to your normal profile i.e default.
What is the max overclock in this phone?? tnx!
Differs on every phone, most go to 940 or 902 stable, if you go higher you will get crash and reboots, but it is possible your gio is not stable above 883 , just try it out, it wont get it bricked

844
844 is the highest stable you can get, but you can go up to 921 mhz but you can get screen freeze and you will have to remove your battery and restart.
I've had problems with over 806, but recently I put it up to 825 and it's stable so far. I really don't understand how some can go over 900, the phone will become unusable. It also seems to be more stable with minimum freq being set to 122 not 245. Currently I have 122-825 with smartassv2 scaling and it's working fine.
One more thing. I have more luck oc'ing with cyanogenmod built-in CPU governor, setCPU with different profiles seemed to crash my call answering dialog too easily. So if you use smartassv2, there isn't much point to use setcpu for screen-off profile.
overclock
in my opinion best clock for daily usage is 806MHz

This.
Others are just stating their own experience.
True, everyone has other mhz that is stable, you just need a bit luck

Just a quick question:
I know how to adjust my Min and Max frequency, but which governor should I use?
My ROM is GalaxyICS-KANG-beta3, and the default governor is ONDEMAND. Max CPU frequency is set to 902 MHz and Min is 122 MHz, the default.
Which of these settings, if any, would you recommend I change? I'm a little intimidated by the sheer amount of governors available to me...

I'm not entirely sure how all of them work, but ondemand is the most neutral choice, that's why it is the default governor on most roms.. it chooses CPU workload according to need (on demand).
Smartass is similar, except it keeps CPU usage to minimum when screen is off (it has a built in screen-off profile). SmartassV2 is an upgraded version of smartass. It's based on Interactive governor, but there are differences on how cpu usage scales up and down.
Minmax uses only minimum and maximum values. When your phone is idle, it uses minimum.. when it's not idle, it's always at max value.
Performance keeps CPU at max all the time. Powersave does the opposite - keeps at minimum. Conservative avoids using high values when possible.
So if you don't need anything special, then ondemand or smartassv2 are the best choices with compromise between performance and battery life imo.
my gio is 940MHz
失败的中国人正在尝试提高！
it seems that my gio is stable at 940Mhz, it got one day 1Ghz but over a day he crashd and i could not set it back to ghz... xD
Ok so i have cm7.2 rc1 instaled with the new kernel. I've changed many different roms in the past to find out i cant overclock over 768 w/o the phone crashing. Anyway yesterday i searched the forum and found out i can overclock to more if i change the governor to userspace. It did work however i ran antutu benchmark and i saw the folowing.
At 864 governor userspace i get 1328 points.
At 844 governor userspace i get 1479 points.
At 825 governor userspace i get 1486 points
At 806 governor userspace i get 1675 points.
At 768 governor performance i get 1644 points.
So my question is could it be that antutu is wrong or is it some something buggy with the kernel or my device.
Edit. And also something that i noticed at 864 the cpu is what lowers the score drasticly and on 844 and 825 its the 2d graphics. I could post SS later cuz i dont have time now if neceserry.

reason is because of governor
Keep it at 806 and use whatever governor you'd like to (smartass2 if you want better battery life and high performance only when running apps). Don't set it any higher, as it could melt your phone and it'll definitely drain your battery a lot faster than it should.
Mine runs at 120 - 787 MHz and "ondemand" governor. If I set the upper limit to 806, the phone would crash when under load (e. g. benchmarking). The settings appear to save a bit of power compared to the "default" values, which is probable due to the so-called "race to idle"-effect. Basically "race to idle" means that higher clock frequencies will save power, since the processor gets the work done faster and can enter low-power states earlier than when running on lower clock frequencies, so if you can clock it even higher you should get even better battery life in the long run, even though this might seem counter-intuitive. Only disadvantage with these settings is that the phone lags a bit directly after booting and screen unlocking, but otherwise is really smooth.
My freequency is 245-864 and i have very stable work. But i have extended battarey (2200mah)
I am using ElementalX kernel on stock 4.4.4 android. I have to OC set to 1.944GHz currently. AnTuTu bench at 1.944GHz and 450MHz GPU gives me between 24-25k result. Now if I lower the CPU to 1.89GHz it drops to 21k. And if I go back to stock freq I get 19k. Something does not seem right in the test results as related to the frequencies. Question is this: Are there sweet spots in the frequency range for the CPU?
P.S. I know many people dislike benchmarks...I'm using it for comparative purposes...

It states it in the thread, having cpu at 1.9ghz is not economical with battery consumption and performance, it Is best at 1.7ghz

You should monitor your CPU temp and frequency while benching.
You would see that your CPU's temp probably goes above 70°C if not higher and so the kernel thermal throttling policies would downclock your CPU's max freq. in order to keep your CPU "cool".
If you first bench @ 1944MHz then bench @ a litle lower frequency and have very lower score then its not because of the lower freq. but because you did first heat up your CPU @ 1944 and when you re-run @ lower freq. your CPU is already very hot and so does a severe thermal throttling.
Last point : running your CPU @ 1944MHz is not good since thermal throttling while happen every now and then.
Not convinced?
Then simply launch the camera app and try to take a video of 5 mins...your CPU will become so hot that it will downclock to something ridiculously low and your recording will become jerky.
I have been searching for some time and i am yet to find any details on bcm21533 governoe for galaxy y.
In my experience it gives performance nearly as much as smartassv2 and gives battery life same or better than ondemand. i find it faster than interactive.
Yet i have never heard of anyone use this governor. anyone know why? isnt it far better than smartassv2 on our phone?
Have tried this governor ornhells fusion and percy kernel.
Indeed it works as this :
Only switching between max and min processor values (832 and 156 for example) depending on needed work, but maybe you are using some heavy app and speed = min it will be laggy , and light app on max freq will be battery drain, so interactive is better for me
I use kuro kernel with
Gov Ondeman
i/o noop
stable for me
I always used conservative and sio, never complained about this
