Okay, so my question is basically how stable is overclocking your g2? I typically keep it at 800 when I use my phone normally, than 1.5ghz for games. I wante d to keep my g2 at 1.5ghz forever.. is that bad?
My battery obviously increases in temp..
I just use 1GH. It's enough for all game now. and didn't see any bad to battery or phone
I've had my DZ for about three weeks now and all this time I've had it consistently overclocked to 1843MHz. At that high of a speed, I had to let the phone cool down after 20 minutes of use.
Just today I flashed pershoot's 1516MHz kernel and noticed no heat issues after ~45 minutes of consistent use (temps < 40C).
I have had my g2 for.... However long they been out. I have always been overclock to at least 1.5 with zero heat issues. I ran 1.8 and even 1.9 for a good long time as well. Those speeds have heat issues ones that required a battery pull a few times because it started heating up faster then i could shut down the phone. If your going to OC at those speeds makes sure you set temp profiles with alarms.

ARM processors, like our snapdragons, are a lot more forgiving on the overclocking front than what you might find in your desktop, for instance.
I still treat overclocking on my phone like I do my computers, though... setcpu has a stress test built in that you can use if you're curious how "stable" your overclock is. but in my experience, I've found that you can get away with just playing around with it and using the phone normally and seeing how it reacts to different clockspeeds.
right now, I run it at 1.1ghz (24/7). I have run it at 1.5ghz (24/7) in the past for PSX/N64 emulators, but I've found with my new setup (pretty light; no widgets, very few things going on in the background, stripped as many unnecessary apps as possible, and not using any animations or fancy bits) that 1.1ghz is more than enough to be able to play the games I play on any emulator smoothly.
you should be fine at any speed that is currently available in the overclocking kernels we have with the exception of flippy's 1.9ghz kernel, which does require some monitoring to keep things cool and stable. but it still does vary from phone to phone. if you're running at 1.5ghz and the phone isn't doing anything wonky, then you shouldn't worry about it. if you're running it at 1.5ghz and you're experiencing stability issues, random force closes that aren't fixable through conventional methods, or heat issues, you should probably back off a bit.
some people have problems at 1.2ghz, some people are running at 1.9ghz all the time and never have problems... just find what works best for normal usage with your device and go with it.. it's not like we keep these things for more than a couple of years anyway, and the processor will be capable of handling the [stable] overclock for that period of time.
im always at 1.2ghz. 768 as min, interactive gov (when i use CM7) and battery has been fine, havent noticed any major issues. hard to tell if it was the rom bugs or OC being the issue but from what i read all my issues others have at various speeds so im guessing it was rom related
i think it depends on the rom.
when i use the Pyromod rom i dont need overclock but for other roms like sense roms those I require OC. I always keep it at 1400 when needed.
Hello guys,
Since a month or a bit less my Arc bootloops every 40-60 hours, mostly while charging. It started without that I changed anything on the device like a new mod or so
It plays the bootanimation again and again and just a batterypull can fix it.
What I did so far:
- Reflashed it without wiping data, didn't help
Mods I applied:
- DooMKernel V15
- Statusbar widgets Indi V2
- Removed Junk Apps
- SuperCharger V6
Setup:
- Overclocked to 1.4GHz
- Underclocked to 122MHz, set it back to 245MHz today to see if it helps
- Undervolted -100mV
- Worked perfect like that for 4 months
I ran out of ideas on how to fix it and hope you guys can help me, as the bug is really annoying, I wake up if that happens at night while charging, which happens most of the time
If you have any idea, post it
Regards,
Flo

Yeah, but I got tons of stuff on it that I don't want to lose.
And I did never do that on my X10 for 7 months and it was never a problem, then I got the Arc...

Those are your problems right there. Try by removing overclock, then undervolt and if all else fails go back to stock kernel.
Ok, I'll try that.
But it was stable for 4 months, that's why I didn't touch that yet.
And I noticed when the CPU can't handle something, like 2GHz oc, the phone freezes for a min and restarts then in a normal reboot.
But I definitly try removing that after I know if the bug appears with the min cpu speed of 245MHz.

Try the 1.6 ghz kernel from doomlord. It is possible that your cpu us a little fried with the 2ghz boot. Might just be more preferred then removing overclock, also i noticed that 1.4 doesn't really give give than 1.3. and only switch to higher values when you REALLY need them

Thought the 1.6GHz kernel is for devices that don't boot wth the 2GHz version which works perfect on mine, it even runs @ 2GHz for a while.

That doesn't mean that it can handle it. Prolonged stress to the processor can cause damage, so the FIRST thing to check when you see odd behavior is this (kernel, overclock, underclock, undervolt).
I won't stress test it @ 2GHz, don't want to burn it ^^
If it isn't fixed with 245MHz min speed I'll flash the 1.6GHz kernel and check it.
Otherwise I'll flash the stock one back, if it still happens then I ask for a exchange Arc. (It has the crack in the case, too)

For the Arc (LT15) anything above 1 GHz is potentially damaging, just saying.
The spike during boot is not much of a big deal, but running it constantly at 1,4 for example, could cause issues.
So be careful. And I don't think anyone will give you a new Arc because you can't overclock enough the one you have!
It's totally stable @ 1.4GHz and runs at lower voltage than stock 1GHz, so there shouldn't be any damage.
If the CPU (is damaged or) can't handle sth the phone freezes for a min and restarts then, never had that @ 1.4GHz.
I don't want a new Arc for more oc, just in case I can't fix the bootloop issue. For oc mine is enough for me

If it were "totally stable", you wouldn't have started this thread though...
And what you describe is not the only indicator that the CPU can't handle your settings. Actually, bootloops are quite common for all sort of overclock and undervolt related issues.
Again, try running the phone at 1 GHz and see if the bootloops still occur.
If yes, try going back to stock kernel and observe again.
It's the only way to see if something is really the matter with the hardware.
Yes, well, totally stable was related to using it, works perfect then.
Just after the timegrame it restarts while charging and while charging it doesn't bump up the CPU speed like when doing heavy tasks like browsing. That's why I am so confused, the 50 hours are the time when it happens, if it would be uv or oc related it should happen before that 50 hours timeframe, shouldn't it?
Exam tomorrow, on Wednesday or the day after I should have time and then I flash the stock kernel again.
Atm it runs perfect for 30 hours now with 245-1401MHz, uv -100mV and did heavy usage today.
Why happens stuff like that when you're busy with school, damn
But thanks for your help untill now.

Update:
It's running for 62 hours now, with 245-1401MHz, seems like the 122MHz caused it, but not sure, it gotta survive some more days to be totally sure.
But why caused 122MHz bootloops after a long time where it was stable?
So happy, that I don't need a new device, if it keeps stable
Thanks again for your help

Another - bad - update:
After ~75 hours of uptime I updated some apps, got a few FCs and then it bootlooped, I remove the oc now...
Maybe it needs more voltage after some time of use with oc?
EDIT:
Damn, I really can feel the loss of the 400MHz, fresh started phone lags, never had that with oc.
Horrible
Ok, that's because of a background progress I guess. 20Mflops @ 1GHz and 29 @ 1.4GHz
EDIT 2:
Increased the voltages +25mV, hope that helps, last step before flashing stock kernel.
Most speeds are undervolted -75mV now, but some are @ -175mV like 800-1024MHz now, had -200mV from one of the CM7 kernels before.
Using it @ 122-1401MHz now.
Voltages:
MHz mV
122 825
245 825
368 825
460 875
576 925
652 975
768 975
806 1025

1024 1025
1113 1075
1200 1125
1305 1175
1401 1175
That did the trick.
Happy user again
But it's strange that I had to increase the voltages imo
Anyways, works perfect again.

Hello all
This is my first post and Galaxy Nexus is my first Android phone.
So, when i bought my GNex it was on stock and I use Stock ROM about 3 days. In that period he never get any warm - not even whet I play Angry Birds RIO for about 30min.
Then my brother install me latest AOKP ROM and Franco kernel - great stuff, but now I feel heat around camera
I use TempMonitor PRO app and this is my results :
all apps close, not starting anything - around 32C
Gallery, cam, some apps started and closed - from 38 to 42C
Playing games (Angry birds RIO, Space, Sentinel HD) - 48 to 52C
My question is this :
Is that normal temp? How does Stock didn't heat that much
Tnx and i hope this will help if someone have the same question
Hi,
Your CPU temp is absolutely normal,no worries.And while playing games it's even perfect.
How does Stock didn't heat that much
Click to expand...
Click to collapse
You're not stock now...
After it depends at what CPU freq you're running,voltage,ambient temperature,etc...but here it's perfect.
I just posted in another users similar thread about their phone getting hot (he said "extremely" hot so hes likely going way past your temps). I too have found my phone to be warmer when running AOKP Build 38. I've run the Stock ROM and LiquidSmooth with Francos Kernel (also tried Provision briefly but it had some issues I couldnt overlook). AOKP gets the hottest by far for me (both at stock CPU and OC to 1420).
I plan on switching ROMs again soon and will take note of temp then
If you use a less feature rich rom you might have less heat issues.
I suggest using the trinity kernel together with a cm9 rom.

Your temps are fine but if you want to find something a little "cooler" try out different combinations. For me, CM9 and Trinity Stable 65 at 1344/384 stays pretty cool while gaming. Ultimately it is going to be a factor of your clock speed. You can adjust the frequency of your CPU back down to 1200 (1190?) and you'll see the temp difference. You might also see it slow down during certain UI interactions. Just play around with it, but your phone is still considered in the safe zone at those temps. They have thermal protection built into the kernels as well so even if something crazy happened your CPU would back off until cooldown and if it can't cooldown, it'll shut off for you but that would be a very rare condition. I've never had it happen and I've ran at 1650Mhz for a long time.
Tnx all for info. Great help!
Hmm it would be nice to get back to Stock but to keep root and maybe to install franco kernel... What you say about that?
It's iritating to play game 5 min or look pic in gallery and to feel heat in phone!
One more thing because I'm new in this stuff :
How to get back to Stock? Is it hard?
Your CPU is probably overclocked, don't worry, as long as it stays UNDER 55 degrees C, nothing will happen, if however, it goes over, it will burn your hand, if you're unlucky, it happened to me, with my GS II...

Hi,
Why under 55°C???
The stock temp limit before thermal throttling is 64°C and in Francisco's kernel it's at 75°C.
And the max before the CPU shutdown is 110°C...The extreme protection and the extreme overheating
So above 55°C no worries...In any case if you don't disable the CPU temp limit (like in some kernels->Morfic,Glados and eventually Francisco but not (yet) in his app) you're good and before 110°C->thermal throttling->lower CPU freq according to the CPU Temp limit.
His CPU temp is actually normal,don't say stays under 55°C....56/57/58/59°C,etc...to 64°C or 75°C,no problem unless you stay at 75°C during 1 hour...
With that you said the guy no longer used his phone for browsing 5 mins in the sun...

55 is a very low number and i would suspect most stock GNexs would go above that routinely under heavy load.
I've had my phone up to 66 and its nowhere near burning. Its warm to the touch and thats about it. Now if you are somehow putting your hand directly on the CPU (i.e. not possible) then yes that might feel much warmer.
Basically if you manage to burn yourself on your phone either its already fried or someone lit it on fire
After playing ShadowGun around 15min I get temp. around 65C?! That is really hot - for me!
I think to get back to Stock... This is way hot for me. What you say about that?
Can anyone post link how to get back to Stock? Guys this is my first android phone and if I get bootloop I will get a heart attack, really I will get one

Honestly don't be afraid of boot loops as you can most likely still get into recovery if that happens and all it takes it's a bad download of a ROM or forgetting that such and such kernel is incompatible. Be afraid of bricks and soft bricks lol. Although if you take the time to read before doing anything you'll be fine. Also just download a sick image for your phone from the tool kit to go back to stock. That's the easiest way.

Hi,
65°C after playing 15 mins of an "intensive" 3D game...I don't see where is the problem...It's absolutely normal...
How can your CPU temp will be at 50/55°C (about,for example) after playing 15 mins of game???
You hope what temperature?
Which cpu frequency?GPU?Undervolt?
Don't focus much on your CPU temp,if it's overheated->thermal throttling...And in extreme situation...just a reboot...
It will be the same thing with the stock kernel,you will get the same temperature under the same conditions (playing)...
Unfortunately that's the way it is right now with dual core phones. My phone regularly gets too hot to even touch when playing games for over 30 minutes. I called to speak with samsung about it and they pretty much brushed it off as normal. I'm running on cm 9 with a franco kernel

There is definately some sort of bug in my note 2 or all note 2 cpus
Iv been trying to find out why nova3 and mc4 have random lag spikes and then smooth gameplay. At first like many people said
Gameloft games arent optimized well i belived that. While thats true to some extent heres what iv found
Using set cpu or tegrak to force the cpu at max clock fails after hitting 38c
Thus causeing lag in game
No matter what setting iv tried the moment my phone hits 38c the cpu
Locks back to 800mhz. My phone is rooted yet there is no way i can maintain the clock at 1.6ghz
Im now using androd revolution rom and that hasnt helped either. Does anyone else have this issue?
To test run nova3 or mc4 any level and stay in there moveing around after the phones warm enough(around 38c for me) youll notice
Stuttering. Check ur cpu and ull find its downocked to 800mhz
Dear nielo360,
Probably, you are reading the battery temp not the cpu temp since note2 cpu throttles at 80 c...
Try system tuner pro application to read real cpu temp...
If you are overclocking or wanna lock the cpu to max speed then you should do undervolting by installing custom kernels like perseus...
Try to undervolt both cpu and gpu...
Also try to lower your brightness to stay away from extra heat that screen makes...
Issue discussed before so you can refer to here :

Hope all these helps...
Kind Regards..

Thanks for the reply, i did follow the thread and undervolted my cpu running at 1.3ghz 1025mv however my phone reaches 67c true temp and throttles very easily any idea if this normal i cant play any 3d games unless im sitting near a fan or ac. Every says they throttle at 80c
It is set to throttle for good reason. It may b irritating but I would let it be and not tamper with it.

The stuttering in mc4 has been driving me crazy.
I also used a tool to measure cpu and find that the game runs well for the first few matches and then it does tend to lock itself at 800mhz and the sideshow begins.
My phone doesn't get that hot, but something is definitely going on. I really hope that gameloft can optimize this game. These games running on ios are so much smoother that it's embarrassing for Android "super phone" users.

The problem is not the cpu its the gpu throttleing as samsung has for some odd reason overclocked it. The fix for this is a bit tricky
If you use tegrak ultmate Do not force gpu lock at 533mhz this will underclock the cpu automaticly and make it unstable after a few mins instead
Set level 0 gpu 533mhz stock
Undervolt if your like
Set level 1 440mhz
1025
Seg level 2 440mhz
1025mv
.. leave the last level at stock 166mhz
Cpu you can scale it or leave it doesnt matter mine is locked at 1.3ghz
This works great for the most part and u wont notice the downclock as the clocks will move between 533 and 440 during heat.

i found that the real throttling problem is a security protocol that Samsung roms have. When the battery reach 41C the cpu throttles (no matter if its only at 60C cpu temp)
i dont know how to deactivate that protocol...but if you want, try CM10.1 or any other AOKP or AOSP roms and you´ll see that there is no cpu throttling unless the cpu reach 80C.
you´ll need "stability test" app (cpu stress testing, and you can watch battery temp), and "system tuner" app (to watch live cpu temp during the stress test)
So I just reinstalled Cyanogenmod after a few tweaks I didn't like - Basically decided I just wanted to start fresh.
I booted up into TWRP, and clicked Wipe > Advanced Wipe > Checked Cache and Dalvik Cache, and wiped it.
Then proceeded to install my CM Mod zip file, followed by Gapps.
Well after it installed and booted up, It crashed and rebooted by itself. Now it's very hot in my room, which i'm sure plays a factor.
So I underclocked to about 1067ghz to be safe.
Im not sure what is going on, but using Cpuz or whatever that app is to monitor the temperature, almost all of the things that show up under the Thermal tab are around 40 celsius. Im wondering, is this normal? It definitely should not be that hot, especially underclocked, right?
Just looking for some answers, and possibly solutions.
Thanks in advance, guys.
Ps, I might post some random posts after this one to get my damn post count to 10 so I can actually start using these forums efficiently. I hate the way it is set up where I can't comment on other threads until I hit 10 posts, and my replies get sent to some random ass forum that nobody looks at lol. Plus I have to wait 4 minutes in between each, which means it will take at least 40 minutes to just actually get up and running on here, lol. You guys should use a different method for human verification, especially since I registered my email.

Okay now it is up in the 50s and I have no idea why. Nothing is really running that intensive. I think that's why it keeps rebooting, from overheating. What could possibly be going on?
It could be overheating does the tab feel hot to the touch?
even so the CPU should be operated by a governor (usually interactive or on demand) so when it's idle, it's supposed to turn off unused cores, and throttle back the cpu0 to 300~ mhz , and then increase the mhz or active core(s) depending on system load (the GPU does this too from 200mhz to 400 mhz), the CPU is not supposed to operate at full speed all the time if it is you either have a rouge app forcing the cpu to do lots of work or something else going on..
Other then that I have always only run the stock firmware in my tablet (to keep knox at 0) so it might be something wrong with CM build you are running
