It's normal. If you're on the faux's intellidemand governor, it changes the frequency based on the load you have on the phone. It does this to save the battery. I highly recommend you to leave it as is, because if you lock it at a high frequency when the phone is not being used, it can drain the battery like crazy.

Oh...but it often work on 1.51Ghz..it is too hot when i watch the video，so i wanna to decrease the frequency..
could u recommend a kernel please？thanks for ur answer!
Go back and get the yank555 aroma version on page 217.. you can set max MHz to a lower setting

What is the best setup to save battery in Setcpu with the stock HTC kernel? What I mean what do you set the high and low at or any other setting yiu mess with. I am a total noon to this and any info would greatly be appreciated.

you might be right but i set it to 192mhz as the low and it went that low. I am not looking to overclock or anything just trying to get the best battery life.
this may be dumb, but is there an app or something that can tell me where im clocked at? I think I'm supposed to be at 1.5 ghz

SetCPU, System Tuner etc. You need to have a custom kernel in order to change cpu speeds. If you're not sure whether you have a custom one or not, try installing one of those apps and if you're able to change cpu settings, you're on a custom kernel. congratulations
thanks man...i am on a custom. I just want to know if im running at 1.5ghz like im supposed to, or does it not run at that all the time?

That depends on which governor you choose. I'm going to go ahead and guess you're on an Anthrax kernel. Each governor behaves differently, but only the performance governor locks your phone to the max speed you selected. I'd recommend intellianthrax or interactive, I personally use intellianthrax or lagfree. Lagfree is a really good one IF you don't overclock, but since you want to run at 1.5 ghz, I'd stay away from lagfree. If you use lagfree, your phone will rarely ever drop the clock speed down below 1 ghz when it doesn't need it.

Yes you are overclocked. 1.18 GHz is the stock CPU speed for our phones, so any number over 1.18 for the max frequency is overclocked

You are always using a governor, even if you don't have an app for it. The governor tells the phone how to use your CPU, basically. See where it says "ondemand" in that screenshot you posted? Well, ondemand is the governor you're using. If you click ondemand, there should be a drop down menu that opens up that gives you all the governor options available for the kernel you're using
thanks man

I like to use the virtuous overclock deamon, it is said to work better. But most roms have not implement it here.
tammyjustin, I assume you're using MeanROM since 486MHz-1512MHz / Ondemand governor are the default settings built into that ROM. I just started playing around with Anthrax kernels and MeanROM a few days ago.
A word of advice if you're going to be playing with overclocking... You need to be aware that you shouldn't use any overclocking tools like SetCPU with MeanROM unless you modify a system file first to disable the built-in clocking and voltage controls, or you can use only the built-in controls. I was getting strange instability with MeanROM before I realized what was going on with the internal clock management and SetCPU (which I have always used). Basically SetCPU and the internal clock controls in the ROM were both trying to manage the clockspeed and it was causing stability problems. Now I'm using only the internal settings and it is far more stable.
MeanRom ICS 2.4
Hey. I have been using meanRom for a while now, and the newest version (MeanROM ICS v2.4) is eating my battery too quickly. I was wondering if there was a way to disable dual cores all the time or reduce the processor speed to try and save some battery. I have never attempted to change max speed or change the number of cores being used before so i really don't know where to start.
I saw in inbREDed 5.2.5 they have a "Core control in quicksettings, change to dual/single core on the fly". Is that available to use in MeanROM?
Any help would be appreciated.

Yes that is correct. but I text a lot and don't need dual core while sending texts. I have to charge my phone twice a day right now. =\
I was hoping I could on the fly turn on / off dual cores or change the CPU speed.
With previous versions of MeanROM I only had to charge my phone at night. I have thought about down grading, but it's pretty stable right now, i just want better battery life. So that is why I wanted to change the CPU settings.

Mikey did say something about his next version (which will be based on the Sprint OTA when it finally arrives) will dial back performance a little to extend battery life. Maybe this is what he has in mind.
Here's my 2 cents.... Overclocking is great for speed but it cripples battery life. I used to be obsessed with OC and quadrants, but then I realized I can't tell a difference from 1.2 GHz to 1.8 GHz. OC can also make your phone unstable. Honestly you probably wouldn't need to over clock if you don't know much about it. So I wouldnt spend too much time worrying about it
Do what you want though cause that's just my opinion

I want to know what's the safe overclocking maximum and governor . I also want to know what's the maximum safe temperature? Is 50c' as a maximum safe? Thanks for your help.

theres no such tthing as safe oc.
each and every cpu had different characteristic thus different capability when it comes to oc. what might works with others might just hardbrick yours. you just need to experiment yourself. do note thats its dangerous. earlier one guy already fried his phone when oc to 1.8ghz+playing gta3.
and for me personally 45c feels too hot already.

I know what you mean. You are right of course. Mine is overclocked to 1.3ghz governor smartassV2 and the max temp for overclocking is my problem now. I can't decide what is the max temp at which the phone should go back to 1ghz . Do you think 45c' as a maximum safe?

then use any app that can create profile to automatically lower cpu freq based on temperature eg cputuner or setcpu.

I'd say 45° MAX. Or even less. And still you can't be 100% sure you won't have any problem.

After I flash the doom kernel V4a, my Xperia s sometimes shutdown itself, I just only lower the clock speed in 192MHz, I don't think this is the reason, can anyone tell me the reason please ?
That might be the reason. Too much underclock there.

as k900 said it might be the reason, try with different governor...and try with less underclock and see if it shutdown
wondering if the phone can get damaged if u changing cpu speed constantly by profiles? not overclocking thought.

And if the speed goes down does it means that voltage goes down as well?
Since i have rooted my sg3 and instal custom room and got setcpu i have set some profiles but seems like my battery drain a way quicker then when it was unrooted. Any advise please

You will need a kernel that supports Undervolting and then you can do it in SETCPU
i suggest Siyah's kernel. im OC'd to 1.6mhz and UV'd at -100mV. my phone is stable

Overclocking your S3 above 1800mhz will SURELY damage your hardware, the most stable and recommended clock speed when overclocked is 1600mhz,1800mhz and above are highly experimental.

1,8Ghz should be possible i guess. The Note2 has the same cpu and is standard clocked to 1,6 Ghz.

Not true, i`am using Voltage Control Extreme right now and set the max clockspeed to 1 Ghz on a stock kernel in ARHD 9.5.0 and saved these settings as init.d script at boot and it works, even after reboots it`s still 1 Ghz.

A friend of mine downloaded SetCPu. She did something and now the phone is just dead. No screen, no vibration. Heck it doesnt even go in recovery. Either the battery is totally dead or we have a very expensive paper weight here.

Maybe, she overclocked CPU too much for long time and burn out the CPU... in which case only solution is replace motherboard
