Hey guys, I just wanted to get an idea of what an alarming temperature would be on our CPU when overclocking, so I can set a profile on my toolbox to drop the GHz when it exceeds x temperature.Thanks in advance!

Battery status today plugin tells me my cpu temperature. I overclock to 273mhz (238mhz TCPMP), normally my cpu temp is around 25-30 degrees. I was wondering at what cpu temp do I shove it in the freezer? what's the safe maximum? The highest I've noticed is 36, but I reckon it must be more after a long drive with TT6.
So what is your highest temperature please?

Normally you should not have problems with the temperature as long as it stays between 10-55 degrees Celcius. When you notice that some applications might crash the phone, or become unstable, that is when you reached the maximum overclocking possibility of your device, not necessarily the maximum temperature. There might be small differences between phones, although they are exactly the same. I overclocked my MDA Compact III to 247 Mhz and don't have a problem of any kind.
Is that 247mhz using omapclock or battery status? And does anyone know what the actual cpu speed is if TCPMP says one thing and battery status says another. I personally much prefer battery status for the today plugin.
Hi anyone does look at the temperature sometimes? My defy (cm7 default 1ghz) is about 40-42 C after playing for a while and there is about 35 C outside. Obviously at 800mhz it is a bit lower. Share your experiences!!
Best regards.

Hi,
i think it is absolutely normal at such ambient temperatures.
My Defy is currently 37C at 26C ambient currently running stability test at 900MHz.
u should try to undervolt some frequencies to get lower temps, check the setVsel settings thread
Hello!
I recently noticed how frequencies 122MHz through 460MHz all employ the same voltage (900mV). I've come to understand that the higher the CPU frequency the faster your battery will drain. What I don't understand is why a higher frequency will drain your battery faster.
Is the only cause for higher battery drain when running a higher frequency, the higher voltage which comes with a higher frequency, or are there other factors?
If, then, a higher voltage is the only cause, then my battery would not drain faster if I clocked my minimum frequency at 460MHz instead of 122Mhz?
Thanks in advance to anyone who can shed some light on this!
Hi
cpu power consumption at a specific frequency is bound to its voltage.
you should test a voltage for a frequency while your device has 100% workload, because you could find a voltage so that your device is stable while being idle, but freezes when it needs to work. (for more information search for linux phc)
my conclusion:
the voltage for a specific frequency has minimum!
you can set your minimum frequency to 460 if you want to, since the screen consumes most power, it should not matter that much. i have set my minimum freq that high, too. I believe that way, my phone needn't raise the frequency when dooing simple stuff, like playing music.... but i am just guessing.
i theory it must get hotter than at lower frequencys, but i did not notice that.
i have had a palm pre and a custom kernel introduced a voltage on demand governor, which kept the device at 1ghz all the time, but changes the voltage with the workload. i think the developer of the awesome idea is "unixpsycho" ... i would like to see something similar on android.
greetings

EDIT:
http://en.wikipedia.org/wiki/Dynamic_frequency_scaling
it looks like it is bound to the frequency, too!
~const*f*V^2
the Voltage is quadratic, that means it tkes a higher priorety.
e.g. lowering the voltage from 900mv to 800mv => (0.8^2)/(0.9^2) ~ 0.79
460mhz*0.79~363mhz
=> [email protected] consumes as much power as [email protected] (Stock)
hi everyone, a quick ? does the galaxy line of phone have thermal compound on the cpu or gpu? and if so is it possible to replace it with some prolimatech pk-3 thermal compound? i know when i did the thermal compound swap on my laptop my temps went down 12 deg C. i notice a difference in the warmth of my phone when i overclock it past 1.7ghz. so i hope the temps will drop on my gs3 if i can put some on the cpu and gpu.

That works fine it's what I.use less is more on stuff like this
Hi there! Could someone tell me the stock cpu voltage table please. It`s 1237 for 1500 MHz, but what is the voltage for 1300, 1200... And so on?
Одг: Stock voltage
I think it is something like this, but I can't guarantee...
