Hello, our cpu should have 4 cores at 2100mhz but in kernel adiutor there are 4 Big and 4 Little cores both at 1700 max, why? Thanks
Found that our cpu has 6 cores at 1700 and 2 cores at 2200, but kernel adiutor wrongly displays 4+4 cores all at 1700.
Tried several cpu monitor apps but all see max 1700.
Also noticed that phone never go deep sleep

Can you fry the phone doing so, and is there really much speed increase?
I still havent fried my G1, im running the latest sensehero and using bill cui overclock widget. I did notice a little change in speed
My phone has been overclocked for about 11 months.
Nuff said.
It's physically impossible for apps changing the clock speed to damage the phone because they don't clock the chip faster than it's advertised speed or change the voltage. The chip is factory clocked at ~175mhz to save battery life, so the chip is simply re-clocked to 528MHz (which it can run at all the time with no problems).
does overclocking kill the battery faster?
Yes (10 char)
I use set cpu for overclocking. It has nice exceptions list for better battery life
it cant fry your CPU because your never actually over clocking it, the CPU max is 528Mhz.... so your just clocking it, but by the time your CPU is done on your phone you will probably have smashed the screen or dropped it in water or gotten a nexus one so it wont have any real affect on your phone
Hello,
I just flashed Cronos 1.2 last night, and after overclocking to 1GHz(62vsel), I noticed that my battery felm warm.
This morning the temperature had jumped up to 38C, but is presently at 34C. I used to run around 28C on CM7 and am wondering if these temps are normal? Should I downgrade my O/C to 900MHz?
Thanks in advance!

38C is definitely fine.
When i surf the web using 3G network, it is always 37C+
you can set a tempature profile using setCPU to lower the clock speed if temp. is high
You can edit /system/etc/init.d/10overclock using ROOT Explorer to change the speed to max 900Mhz. Also try to lower the vsel in the 10overclock file, it saves a lot of battery life
Right now, my overclock is set at 1GHz, with a 62 vsel. I have a stable overclock file from FroyoMod 2.6.0, that would save me a lot of battery life and it was clocked at 900MHz, just curious as to what are normal temperatures are, I'm used to sub-30C on normal browsing
I generally try to keep my battery from going any higher than 32 when browsing the 'net, but I did notice that on higher vsels it got hotter. I wouldn't call it dangerous, but remember that the more you're draining the battery, the faster it'll die. I don't mean lose its charge, I mean it just won't hold a charge any more. Lithium Ion batteries are rated for 500 charges, so if you need to charge the phone once a day, you'll be out of a battery in a year and a half.
If it reaches 40+ I would start to worry, though. The difference from 900 MHz at 52 vsel and 1 GHz at 62 vsel doesn't warrant using, in my opinion.
It looks like the spike to 38C was a random spike, because right now it is anywhere from 32-34C, so I think it might have just been one spike that made the phone get really hot!
I also think that the milestone is getting really hot. I think thats kind of annoying
Well right now I have mine at 29, sitting idle with EDGE turned on.
During the day time I've seen it going from 32 to 34.
With HSDPA and Wifi Tether turned on, I've seen it went up to 54.
That is my experience.. and yes 54 is HOT... usually I just turn off tether for a while, until the temp drops to 40+ before I re-tether.
I had my other phone touchscreen spoiled because of the prolonged heat. Bad experience..
Hi guys,
What is safe Tegra 3 temperature? I tried SetCPU stability test for 20 minutes at 1.6GHz and System Tuner Pro showed 72C. I'm correct, 80C is bad? I also suppose SetCPU stability test is more aggressive, than games or any other apps.
I user to run v10a firmware which often ran to 80° with no ill effects. I would be concerned if it rose any higher. The phone is built to shut down at 90° so I wouldn't worry too much, it can handle the heat
Sent from my smart frying pan (Tegra 3)
i had my device shut down twice while running werewolf with no skin throttle. i put the shutdown temp at 80 degs celsius. this happened after an hour of gaming. so yeah, it could probably run even more. i think default nvidia's shutdown temp is 120(!) degs celsius. not sure where i read it though.
I have throttle set to 75 and shutdown to 85. This is more than enough for me.
I wouldn't let my device go anywhere higher than 80C... It might be able to handle more than 80, but I'm not willing to risk it

I saw it from a kernel's changelog (don't remember the kernel's name), it said in the changelog "Tegra 3 default safe temperature : 85 C"
but I wouldn't recommend going above 80 C, it would reduce lifespan of your phone, not even mentioning the battery.Since battery is pretty close to tegra 3 chip, it gets effected by the heat chip generates
The main problem with high temperatures is not the chipset-temperature but the battery shouldn't get too hot. Li-batteries will be destroyed on high temperature. It's around 50 °C.
Did you hear about bloated or exploded phone batteries? This were cases of high temperatures.

Strange thing. Hot in the SoC area (top), not at all where battery is.

Because it is actually the SoC what gets hot. Look at temperatures in Trickster mod (or any similar app).
Better be careful, be careful burned out CPU

It's just one thing - Tegra 3 chip is awful. I watched a lot of review of Optimus 4X HD, but not in one was talked about awesome hot, sadly. Though Tegra 5 are looking very nice now with Kepler GPU, but I'm furious on nVidia and when I will buy phone next year, it not will be powered by nVidia chip. I'm crossing fingers on next gen Intel Atom SoC.
Hey guys,
can you share your CPU stats - usage and temperature? ~45* and 21% on 1300MHz seems weird to me, especially I only used a launcher and a browser. Note is in a Protective Cover, but I don't think it should make any significant difference in temp. Maybe I'm wrong or these temp and usage are quite normal? (phone is new and I still have a few days to return it in a bad case, that's why I'm so curious)
If i'm not wrong, Cpu Spy app only shows A53 Cluster's frequency.
Try using CPU-Z or AIDA.

A53 cores run on 1300 mhz basically whenever you touch the screen. But you can also experiencing fingerprint problem.
Ok, but what with temp? Now I'm jumping between Chrome, Messenger and FB and temperature is ~55-60*C. My hand feels that pretty well...
Does anyone know how to stop the Snapdragon 845 CPU from going into overdrive and using up the battery quicker?
Thanks
