I am using speedmod kernel or some times the stock kernel
my Cpu is speed up from 800 to 1200 mhz without pass in 1000 mhz
cpu spy show that the less used speed is the 100 just for 1 min in 24 hours
is that normal or is a kernel or my cpu problem
Thanks in advanced
That's normal. Some CPU steps are just used less because of how you use your phone.

I see but can you tell me which app need the 1000 mhz speed
I know my question is difficult some thing
sorry I can`t press the thanks button cause I exceed my limit number of thanks I will give it tomorrow

the cpu attains that freq (1000mhz) only when the same is needed ,cant specify any app that uses the same for u, so please stop wasting urs as well as other members time

Hi All,
I am writing this post to know what are the pros and cons for overclocking the phone. I know it helps to increase the clock rate, however if the phone can support it, why didnt the manufacturers made it that way.
And if we do it, are there any chances that the phone might blow up and stop working or something.
I tried to search on this topic but cudnt find anything.
please reply
Iam using LG Optimus One
Thanks !!
Hello.
The main plus is the increase in productivity phone.
The downside is that, theoretically possible to burn the phone, but I repeat it theoretically.
I myself have clocked the phone and nothing terrible has happened to him.
I don't think anything's going to burn as kermel always goes in panic if it can't handle it.

The processor won't burn, as 4silvertooth says the kernel will panic and you'll end up in an endless bootloop; 729 - 748 mhz is safe, 800mhz in most cases cause the kernel to panic.
Well oc has nothing to do with proceesor (don't laugh). Well at hardware level the clock (MHz) and processor are two different thing the crystal provides the MHz to processor and in return it computes at that speeds. So by oc we are telling crystal to oscillate at higher frequency. So if our processor can't handle higher frequency it tells kernel get lost I am not doing this for you as I am not able to execute instruction at such speeds. And all the governers are nothing but a rule for processors to execute tasks. Like if you select performance governer it tells CPU to execute at Max speed you have set. So what ever you set the min frequency it always uses Max speed no need to change min if u r using performance governer same for powersaving governer no matter what you have set for max it always work on min. So all the governers has different sets of rules.
Pros: CPU speeds up the execution
Cons: Crystal may get hot.
Bye.

No you wont go in bootloop.
Let me explain.
You will go in boot loop if you have set speed that processor can't handle and selected set on boot option. As the processor can't handle it and you are telling it to be always in that mode. Dont select set on boot. After reboot manually select oc. The second reason would be currepted filesystem as after kernel panic your phone has rebooted with unsaved changes chances are that filesystem table is currepted. Theres a command to check that I forgot name its like chkdsk for Linux. But no rom impliments that on unhandled reboots.

i'm more concerned about the processors life. can overclocking to 729 in long term kill the processor.

Even I am concerned about such facts, and also why didnt the manufacturers made it that way if it can support such speed without any problem.
Thanks for those who replied, Much appreciated
It heats up very quickly with the new update 2.3 the
998 MHz microprocessor works all the time.
view with setcpu or temp+cpu v2
you check it is not normal
It is the work of the microprocessor in the update 2.3 Whenever
is at 998 mhz.
in 2.1 this happened I never ever was 245 MHz but is now only 998 mhz
any solution?
Are you sure?
But i thinking SetCPU working not properly.

I can not confirm that.
Pointed this out a while ago with no replies from anyone. If you look at time in state in setcpu, you see that both go up at the same time but more time is spent at 1ghz. My phone is staying cool though but I'm worried about the cpu working too much.

This program shows how much time the processor runs at a given frequency.

i can confirm
cpucpy state :-
998 mhz = 52%
768 mhz = 0%
576 mhz = 0%
384 mhz = 0%
245 mhz = 1%
Deep Sleep = 45%

Same here. Always on 998 MHz or Deep-Sleep. ~1% on 245MHz, the rest nearly 0%...
but it's weird, battery life is great...better than 2.1, yet all it's using is 1GHz or deep sleep, nothing inbetween...
i can not confirm this
998 - 0:10:17
768 - 0:00:06
576 - 0:00:03
384 - 0:07:31
245 - 0:03:17
DS - 1:09:10
im on wb with hotfix 3 and bravia engine
I was having same problem... heating and eating a lot of battery
I've found out that was an application that was killing it.... I've removed the app and now is rolling well...
CPU does indicate 998Mhz all the time even when it's not doing anything... Does this "ruin" the CPU?
Cheers.
Flashed Faux123's Kernel acouple days ago and have a question.
Does this Application need to be running for the voltage changes to work? What about for the profiles set?
Thanks.
i don't know the answer because i haven't flashed a kernel. the quickest and best answer is to try yourself. setcpu is in the market.
I know, but it's hard to tell and I really don't want to undervolt too much more because I don't wanna see a crash, although I have yet to experience one. I have it set at
Respectively:
-100
-100
-50
-75
-300
-300
-300
Seems stable with and without SetCPU on while spamming Quadrant standard benches and I cannot tell if the voltages are working or not. Those extra volts being taken away can greatly help my battery life, but if it's not working without the program on there is literally no way to tell. I use Advanced Task Manager a lot and it takes out SetCPU all the time.
Maybe someone with more experience of the program can help me out.
why do people undervolt it? Why wouldn't Faux undervolt when he created it? I don't touch the voltages, but not sure how you test if undervolting would hurt performance.
There is a bunch of responses to undervolting in faux's kernel thread in the dev forum. But long story short u can't have more than 100 m's between jumps when setting your undervolting, or it simply wont apply it. Example.

Well, I've been overclocking computers for years and something I've learned is that the lower your voltage is, the less degraded the processor will be after awhile. Such as, if you overclock the voltage too high, overtime you would need more voltage to obtain the same speed. Same thing applies when overclocking graphics cards.
Edit: Anyways, why are people dodging the main question
no you shouldnt have to keep setCPU running. i believe the app is just changing some sysfs files, so its one and done till the next time you open and change more values.

Bro, this setting is left 770-470 = 300 or 770 - 300 = 470mv ?
Hello,
I'm writing this thread to know which processor options would be optimal in our minis. The best settings, which give me the best performance/battery, I've found are:
CPU Governor: SMARTASSV2 (Default)
Min Freq: 19MHz
Max Freq: 748MHz
Undervolt: TRUE
I'm also using Apex Launcher. Which settings are you using?
Note: This are just my results, be careful when you change your processor settings.

Whats the purpose of Undervolting when you have it's max frequency as overclock?

Because it undervolts on every frequency below 600, and his minimum is 19, so when the phone is idle or doesn't need all of the processing power he saves battery
The SmartAss governor is very good at picking the right frequencies for any given job, so it doesn't allways run on 748Mhz, not even when you're using the phone.

That is the same very purpose of SMARTASSV2 to undervolt your device when idle or on sleepmode and overclocks it when on process. So ticking the undervolt wont affect your device because the one that manage the frequency will be the COUgovernor.

The SmartAss Governor only governs the frequencies, not the voltage that the Processor uses. there is a difference between the speed the cpu runs on (Mhz) and the amount of Electricity (Volts) it gets fed
Say Qualcomm has said it needs 5 volts to run at the stock frequency of 600Mhz, then the processor will always get 5 Volts, no matter which frequency it uses.
Undervolting will feed it less than the 5Volts when the frequencies are lower, SmartAss won't do that, it will run the 19Mhz still on 5Volts.
(Voltages are examples, i don't know the exact values, but I know that running on 122 or less will be stable on less than half of the nominal power)

I just installed the cpu-z to see the processor information and i notice that the maximum clok speed of s2 is 1.20 ghz but it only reach maximum upto 800mhz the clok speed not reach it maximum at 1200mhz why? What is the problem explain i am in worrie.

Powersaving mode limits your CPU to 800mhz.
