[Q] Constant overclocking safe? - Galaxy Note GT-N7000 Q&A, Help & Troubleshooting

Setcpu determines that 1704mhz can be achieved, would it be safe running the GNote at that constantly does anyone know?

Hmm...
I would say, this is depending on more than only the frequency,
if you set the voltages for 1704mhz on e.g. 1650mV u'll get a very hot phone and a hot accu... this will not be good for ur phone, if you're doing this constantly.
But if u find a good compromise between voltage and frequncy, u can do this constantly.
Also you could make profiles in SetCPU so that for example if you're gaming it will set voltage and frequency to 1704mhz and if your screen is off, it setz frequency to 800mhz.
So you have to decide if u'll want to take the risk...
I hope i could help u and sorry for my bad english,
Schnizel.

Aside from benchmarks theres no real benefit from running at 1.7ghz. Most of the time thebphone stays at 200 to 1200mhz

safe?
thought overclocking is always a risk. think nobody here will tell go do it its safe is there ?
and why would you overclock a 1,4ghz dual core in a mobile ?

Thanks, i've seen in a different thread that the voltage would need to be lowered so overheating isnt too bad.
SetCPU gives information on what frequencies are used by percentage and mine is either minimum or max so it suggested its topping out while doing stuff....

1.7ghz is too much for a constant setting.
I had my phone at 1.7 and while watching Netflix on 3G, it would get TOO HOT. and i mean TOO HOT.

[Q] Kernel for CM7.2 Stable that allows OC and governor change

I have just updated to Cyanogenmod 7.2 stable on my P990 Optimus 2x (Fido Canadian version).
When I go to the CPU settings I cannot change the min/max frequencies or select a CPU governor.
I have done some research and found kernels like Vork and FauxDS, but they are for 7.1 nightlies so I am not sure if it is a good idea to flash them.
What I am most afraid about is the possibility of getting the black screen of death while my phone sleeps (it happened once already but it stopped after I changed to a different charger and reflashed CM7.2).
The reason why I want to change the settings is that there tends to be scrolling lag (my old HTC Desire Z was faster!) and there is also a bit of lag waking up the phone (lockscreen does not appear instantly when pressing power button).
Does anyone know what is the best kernel I can flash to enable frequency/governor changes in CM7.2 stable? I would prefer not to change the ROM if possible as I am kinda nooby in comparison to the XDA community in general. Thanks for any help.
I suggest you try Etana kernel. It has the things you need. Also use CPU master to set profiles and minimum CPU frequencies. I used something like min freq 352 MHz when asleep (don't worry doesn't drain battery) and I had no lag whatsoever.

Are you referring to http://forum.xda-developers.com/showthread.php?t=1427646 ?
If so, do I just flash the zip off the sd card using ClockworkMod? And what are the differences between lite and DS?
Thanks.
All right, after reading, I determined I don't need LOC/HOC/DS as I don't intend to raise the max frequency, I just want to raise min frequency.
Installed the Etana kernel via CWM and it works. I can raise minimum frequency, though I still cannot see a governor option! Any idea how to get my governor setting back?
You can use CPU master and set some profiles. It's not exactly the same as governors but it's as close as it gets and it gets the job done pretty well. As far as I remember there were two governors for O2X - powersave and performance. I've always used performance and I can't tell if there's a HUGE difference in battery usage. I guess performance utilizes higher CPU frequencies when the device is asleep and somehow scales faster to even higher frequencies when needed to. But this might be complete crap as I am not too much into how CPUs work...
And please use the THANKS button (right below the user name), it kind of forum etiquette and it keeps people motivated to help others. Thank the Etana developer too.

Thanks for letting me know, I didn't realize there was a thanks button at first haha.
Fixed!
As for now CPU Master in his profiles let's you choose governor. We have only 2. Power save nd Performance.

[Q] CPU frequency throttling

hi all
im using DooMKernel for a while and when i set the maximum frequency for any speed faster than [email protected], when the cpu is on heavy load or when the phone temperature is rising above some threshold (i think it's around 45 degrees, not sure tho) - there is an automatic down throttling to stock valus (max 1.5ghz) and nothing will recover it back to modified values unless reboot or reapplying the OC via SetCPU or equivalent.
now, i know there is a 'thermal control' sort of mechanism, and i also know it probably resides both on os level and sony framework, but i wish i could disable it somehow.
i know there is a great risk of frying my XZ, but im only intend to overclock for short terms and not for a main daily usage.
a quote from DooMLoRD's post on the subject:
It has been observed that the overclocking sometimes reverts back automatically to stock settings especially after heavy CPU load and if the device heats up.
I think have found why this happens:
Android OS level
there is a binary called: /system/bin/thermald which writes lower CPU freq values to the CPU sysfs interface if the device starts heating
there is also an app "Overheat Control" which i suspect is doing something similar
Kernel level
there seems to be some sort of fail-safe in place "msm_dcvs" which resets the CPU to 918Mhz or 1026Mhz or 1512Mhz
could also be some other things i am still searching
now there are ways to circumvent these issues but given the risk of the damage associated with overclock for long time i think its in our best interest to not screw with these fail-safes...

if someone could plz explain how to totaly disable thermal control - it would be much appreciated.
if you totally disable them your Smartphone will shutdown every time you reach....(cant remember! think it was 75°C) SoC Temp! and you will reach that kinda fast!

Help for OC and UV!!!

hey i needed some help on overclocking and changing some voltages on my device!!
1.i have read threads and guides on other forums before which explain how to OC and what are governers and schedulers etc.
2. most threads on this topic are from different devices' forums
so i thought their frequencies voltages must vary as they have different CPUs and hence started a new thread!!
3. What i want to know is, what voltages should i choose at different frequencies??
or it is completely not important to set voltages??
4. Earlier i used setCPU but it doesnt stick to frequencies i set and resets default 1024 after reboot.
how do i avoid this??
Currently i am using AnTuTu CPU master PRO for doing all this
please guide me if possible provide specific values on which htc incS performs good!!!
my system details are in my signature
any help is appreciated!!

I've commented on this 100 times before but I can't search on mobile. So there are a few threads out there explaining this in this forum. If you can search and find them they'll go into a little more detail than I'm about to.
OK so the OC controller you're using I'm unfamiliar with however they all do the same thing. What you should do is find out which governers your kernel supports and than use Google to figure out what their perimeters are. Generally speaking you're going to want to have different profiles set up for "screen on"and "screen off" for your basic set up. Later once you understand why you're doing you can set the governers for gaming, charging etc.
Set your screen off for around 200 min and 400 max. This will keep your phone from running high frequencies that will drain your battery while you are not using your phone. Set the governer to smart ass or on demand, read about them and see what's best for you.
Screen on set to max 1200 - 1400 if you want high performance and the low to whatever you like just not above 400 as it will not allow your CPU to idle. Set governer to smartass. You don't really need to be running above 1100 for most I stances however you will notice it is a bit peppier. While running at higher freqs you will notice your phone heating up... I have never heard of an incs over heating and frying in every case your phone will shut itself off or freeze. If you're afraid of overheating there's a profile for that too to change your freqs at certain temps.
Do NOT choose "set at boot" until you are certain that your set freqs will not hang your phone, doing this will cause your phone to freeze as soon as your ROM boots up causing a boot loop and you will have to revert to a backup to fix the situation.
As for uv'ing the premise of this is to save battery life, running at lower freqs than intended. I recommend not bothering but if you do want to try and save battery I generally suggest -10 for all values. Be aware it is very common for this to hang your phone. You have to tinker with it to get it right for your ROM.
Hope this helps any other questions just ask.

Clocking problems

Hi,
first, I want to apologize for my bad english.
I have a problem with the clockingspeed of my HTC One.
I was impressed by how bad the battery life of the One is.
I found out, that the CPU is always clocking at 1,7Ghz, both values (Min AND Max) are set to 1.7 Ghz.
If I turn on the battery-safe option, it clocks at 1Ghz, but again on both values.
So, I have downloaded some CPU apps, which should let me change the clocking speed of the CPU.
Well, it works, but if I turn on "Set on boot", and reboot, the values are gone.
I thought, this would be caused by the stock ROM, so I have flashed the "InsertCoin" ROM, but no changes.
Has someone the same problem, or does someone has a solution for me?
regards.
The clock speed is dynamically controlled. When the phone is not in use, it should reduce the clock speed.
It sounds like you have an app that is preventing it from sleeping.
Install betterbatterystats and look for partial wakelocks. Feel free to leave a screenshot here.
Hi,
even if there is an app which would prevent my phone from clocking down, the MIN-value should be at 300/400mhz, and not be the same as the max-value ..
regards.
No idea..?
what hes saying is theres a rogue app mostly likely in the background thats pushing your phone that it thinks it should ramp up the speed of your phone. so even if you have it set to 384/1.7 the phone is detecting "oh **** *so and so* app is beastly bump the speed to max 1.7. bad analogy but you get the idea. i would start by wiping the phone install a brand new rom and DONT install anything just the mhz reader. then check. if your on a fully clean flash and still holding at max value all the time. then next is to check the CPU governor. it may have been set to performance at some point "accidentally" the performance governor forces the phone to hold at max speed. mostly only used for synthetic benchmarks.
Nope nope nope.
Nope.
I just had to S-Off my phone ..

Crazy overheating problems with Stock Kernel and even more with Stellar Kernel. Help?

Hello, I'm using Titan Stock ROM and it was working quite OK, but I noticed that with high CPU usage during longer periods of time (Like when you are calling on Skype with both webcams on) after like 5 minutes (depending on ambient temperature) the CPU throtling kicks in and you can barely end the call because the whole GUI of Android gets completely unresponsive.
Quick questions:
- What is the maximum "safe temperature" for the CPU to not break? 60ºC is way too less.. as it gets easily to that temperatures.
Now in hope of getting this a bit fixed I recently installed the "Stellar Kernel". I set the CPU settings as recomended on its kernel page (Undervolted to Min Freq. 98MHz and Max Freq. to 1190MHz). Now its just a nightmare. It overheats even quicker.. and when it throttles you can just pray to do anything.. (I changed finally to Min Freq to 385MHz but that doesn't helps much).
And on the other hand thanks to the underclocking the phone doesn't wants to wake up during minutes.. which is quite unpractical when somebody is calling you.. you can hear the phone ringing but you cannot accept the call because the phone doesn't want's to wake up. But that got somehow fixed putting it back to the Min Freq. +300Mhz.
Just want to know if somebody knows about some magic setting which allows the phone to function properly during longer time.. as far as I'm aware 1190MHz is the original maximum Freq. of this phone so no overclicking is done here. So it looks that the only way to have it working somehow decently is to underclock the maximum frequency and leave the minimum frequency high enough to work properly. I don't really care about battery anymore, as I just need the phone to be functional, and as it is now it's just not. Any advices? Thanks for any reply.
You probably have a hardware problem

acquire kernels and other que rooms have different governors Study on them and the Best That was enough pro you and your needs .
I think this will help you , give will take this need to manually change the clock all, the governor will operate according to its governor preferably .
