Successfully OCed to 1.2 ghz (80 voltage) on motorola defy. My temperature is going up to 41°c from 37°c within 10 minutes of PSX gameplay...is it safe? and how high temp goes up so that it is on the safe side. I mean is there a limit to the temperature of the CPU after that it's dangerous?
Also should the freqeuncies of Max and Min be same? what's the difference
Please i need a fast reply on this !
thanks in advance
no reply? don't tell me no one knows this?
The min and max should not be the same. Min is the lowest you want the CPU to scale down too and max is the highest frequency you want to overclock too. On my HTC Desire min is set to 245 mhz and max 1113 mhz.
I don't know about the temperature, someone else should elaborate on that.

You should be fine... These CPU's are designed to run without a fan or cooling of any kind.
It's time to Overclock our Phone...
DISCLAIMER: OVERCLOCK IS DANGEROUS FOR OUR PHONES
How to:
1. Now download r151 from Here
2. Put the files of r151 in the root of SD, run HARET.
3. Download SetCPU from Here and install It.
4. Now open SetCPU, And choice "Autodetect Speeds Reccomanded".
5. Allow Root.
6. Press Windows button and choice "Perflock Disabler" and "Attemp to Disable Perflock" and Check "Set on Boot".
7. Now, close the windows and OC our Phone.
My phone under USB and AC run at 825 MHz without Crash, i had tryed to run it at 864 MHz but System Crash everytime. Without USB and AC my phone run at 787 MHz. I Post 2 Images 1. = Normal Clock 2. = 825 MHz Clock.
To Made Benchmark i Use BenchmarkPi.
1. Screen Normal Clock
2. Screen 825MHz
For Other Question:
1. SetCPU
2. -r0bin-'s Post
I did it, it works perferctly !
Upscaled to 825 and min 128
Downscaled to 245 while charging and screen off
Thanks !

Tell me please, does it helps to save the battery in last releace (r163)? I`m asking becouse i try to use Master CPU, and it seems to me that it don`t helps to save energy... But I don`t use profiles, only ondemand settings from 120-600 mHz.
Thanks!
@HTCxxxx
what is the percentage priority by profile?

To PowerSave try 19-480 MHz if Don't need Performance or 19-600 MHz Im Sorry But i Don't Know Master Cpu

In Call is 100
And Screen Off 100 too.
19 Mhz does not work for me. Phone gets unusable slow and dont come back :/
Beside that, underclocking do not have a big influence on the battery consumtion.
Undervolting would be more interesting.

Why Unusable??? Yhea, Undervolting can be an Interesting Thing, but i Think if the Volting is too low phone Freeze, and if is too high cpu can have an High temperature if you're stressing cpu and phone can freeze too. But i've noted, when i use a low "screen off" profile battery consumaption is high? why? is a problem of kernel? or is nomal?

you are right,i also experienced that 19 Mhz makes phone lazy
i'm also agree about 2nd part..i read the same

you don't need to undervolt it too low,you just need to find the right voltage
try last kernel from r0bin and you will not have high battery consumption anymore
Low Mhz does not lead automaticly to low consumtion.
If you phone has something todo (update something for example) it will get the job done faster with high Mhz and is going fastert to sleep after that.
With low Mhz it takes longer and so can have higher consumtion.
On my HD2 I dont use profiles (like screen off) and it has a very low consumtion on standby/sleep.
If you set a minimum speed when screen is off a11 is not able to go to suspend, maybe
just a quick feedback on power consumption:
it never been so good with r167+drain fix without SetCPU
when I set profiles with low frequency (19 or 128Mhz) it keeps on consuming battery up to 100mA. when i switch SetCPU profiles off, i go to 9mA in suspend mode.
true story
there must be a way to setup SetCPU in a way it doesnt affect too much battery drain in suspend mode, but for the time being i just deactivated it.

Hi All,
I've understood why CPU doesn't run @ 19MHz or @ 128 MHz...
Go to /sys/acpucloclock and look acpuclk_tbl...In It there are write all frequencies CPU can Run:
245760,400000,480000,600000,768000,787200,806400,825600,844800,864000....
but no Under 245 MHz so if You use a Profile for Screen off From 19MHz to 254MHz, cpu Run everytime @ 245MHz...so there is an high consummation of energy
bye

hi
as codiak said earlier lowering CPU(underclocking) doesn't have so much impact on battery life..he also explained you why..if you want i will explain you too
explanation:run CPU at low voltage,open an app or downloading an email,etc= CPU will take time to get to the level app needs,display will stay longer while it CPU will get done the job= worse battery life
Undervolting will have impact on battery life
explanation:run same CPU clock at lower Voltage= CPU will use less power=better battery life
hope it's clear enough for you now,and if anyone else thinks i'm wrong feel free to prove me i'm wrong
P.S. Anyway i asked devs and they will lower CPU to run @ less than 245 Mhz.
Enjoy

Ok thank you very much!!!
Hi. Trying to understand SetCPU.
There are two things I don't understand. That is MAX MHZ and MIN MHz...
Have seen some screenshots that people only change the MAX MHz. Why? And why not MIN MHz?

In essence it's to let the phone run at slower speeds when it can. This helps keep the phone cool and preserve battery power.
When I used SetCPU I used to create profiles to slow the phone down (lower the MAX) progressively as the battery % got lower. I also set it to Lowest/Very low when the screen was off.
Even now on my Sensation I'm at 192/648 screen on and 182/384 screen off. Obviously YMMV, it depends if the stuff you do on the phone works well enough at the lower frequencies. If I find it too low for something I just crank it up.

Thanks man!
Hi All,
When I try to use liveoc my phone hangs.
I have noticed the following:
for 105 - min needs to be 200Mhx
for 110 - min needs to be 400Mhz
The int voltage I am using for 400 is 1000mV and ARM voltage of 975.
As the stock int voltage for 100Mhz is 1000mV and ARM for 100Mhz is 950mV, hence it would only mean a little more battery drain than being on stock, which is fine by me.
But just wanted to know if setting the min to 400Mhz, would it cause a problem? Reduce life of my phone etc etc? I do know there is a deep sleep state. Would this compensate the min being set to 400Mhz? What exactly happens to the clock speed on Deep Sleep.
Thanks for any info that can be provided.
So I'm trying to understand something about our phone's voltages. Say for example if i set it up so that at 300 mhz freq, the voltage is 875. And my 400 mhz freq is at 810. Does the higher voltage of the 300 step mean it consumes more power than the 400 step? If so, in this situation, is it better to keep the min freq at 400 rather than 300?

Yes, if you're running both steps for the same amount of time, the higher voltage would most likely equate to using more power. Your min frequency should be 300 because it is being in this frequency that deep sleep triggers.
No idea why you set 400 lower voltage than 300. If 400 is stable at that voltage, 300 would be more stable at that voltage. The lower the step the lower the required voltage to maintain stability at that step.
