Hello to everyone! I've got a question: everyone knows that galaxy nexus cpu was made to work at 1.5ghz but it's downclocked to 1.2. Developers did a lot of kernels that can increase cpu clock. Now, everyone knows also that overclock brings instability sometimes and may damage permanently the phone. If it's true that our cpu is made to work at highest clock,can we consider it an "overclock" that includes risks like every overclocked kernel do,or it's safer than other phones overclock? Also,(here i appreciate some developer statements) the method used by kernel developer to overclock it's the same used by google own developers? Thanks in advance!
You can oc to 1.5ghz if your phone can handle, there are no more risk than flashing a kernel. But if you try to oc to 2ghz,there are a lot of risk. My phone is okay with 1.5ghz very smooth. If I want to go to 2.0ghz my phone freeze but work after pulling the battery. No fire. Try, and see if it works.

I know,eveything works fine up to 1.5 ghz. Even if battery sucks,it's ok! But i want to know: if i'll use everyday my phone overclocked may i damage it?

No, but it depends of the temperature of your phone. If your phone is at 100°c yes it will damage your phone, return to 1.2,but if your phone's temperature is lower than 65°c all the time, no problem.

Hi,
No,CPU temperature...
In any case there is a thermal protection for the CPU...The limit depends of the kernel you will use.
Stock is 64°C,some have a limit at 75°C and for others you can disable the thermal protection or set a higher CPU temp limit.
In any case the max CPU temp is 110°C after the CPU shutdown...
If the limit is at 75°C,at above->thermal throttling->lower CPU freq to prevent damage.
There is already some threads about CPU temperature wher you can find what is normal or not.It mainly depends of your CPU settings/usage obviously...
But some phones can't handle some higher CPU freqs...

1.5ghz is fine no damage should occur seeing as how the cpu in our phone is meant to run at that speed but was uc to probably save battery
Question. Why was it underclocked to begin with?
To extend battery life, probably

Re,
If you use Francisco/Glados/Morfic's kernel they have their own applications with a ton of features/settings and in this case the CPU temperature->Go to the dev section
In the Play Store System Tuner...Hum...there must be others (though perhaps not that much ),but I don't remember...
While the CPU in the Nexus may be the same as the 1.5 Ghz ones in other devices you have to keep in mind that when a manufacturer knows they will be underclocking you will potentially get the cores that were made for 1.5 but couldnt handle it and therefore used for this application (all about yield and bin rates). So while most phones are likely fine at 1.5 Ghz (phone does get warm) its not a guarantee it will work
I'll try some apps to monitor my CPU and i'll update this thread with my personal experiences after overclocking/switching kernels. Thanks to everyone!

I'm now using aokp build 39 + franco kernel r190,1228 mhz max cpu,384 min,ondemand,384 mhz gpu. During deep sleep the average cpu temp is 42°. Using the phone (wi-fi activated,messagging and xda app) it reaches 55°. The max temp was reached playing nova 3 for about 20 minutes: 72° (overclocking to 1500 mhz and using interactive governor). Are this values normal?

TempMonitor is the one I use.
It'll be fine.. CPU gets throtled if it goes over 63C, unless you're running a custom throtle temp, or your kernel changes it. Shame they gimped these 4460's for more mass produciton and I think they were having stability issues? Regardless, this phone still flies @ 1.2.

Hi there, thinking about getting SetCPU - I have some questions before I do because I hear it can be dangerous?
- I've heard it can brick your phone?
- What if you set it too high?
- Do you personally have to monitor it?
- What are the benefits?
- Use alot of battery?
- Is it really worth using?
- Is it optimized for different phones - example the One X?
Thanks guys!

Hi, i have read that SetCPU cannot view all the cores i have read alot saying that System Tuner works fine you might want to try that.
I used to use SetCPU on my sensation and never hand any issues with it i did not monitor the app at all
Benefits allows overclocking if available in kernel
it can be overclocked and cause some issues such as overheating but if set correctly will be fine doesnt use much battery if any
and no i dont think you can brick your phone
if you set it too high i believe i had to reflash rom nothing major
BTW this is based on my own knowledge and usage
Hope this helps

None in theory, if the CPU is slower it takes longer to go from
idle - process - idle
Faster speeds allow it to get it over and done with faster and get back to idle.
Of course it will at times stop the CPU going higher than it needs too which could save battery.
Under volting will save more batter then underclocking ever will.

undervolting requires your phones kernel to support it, currently on these forums there is only one that does but i haven't tested it, sticking firm to the "stock kernel is best" and will do untill the kernels have more time to mature.
you could limit your max speed to 1 GHz, if you are rooted you can use Core control to turn off cores and run your phone as a dual core.

Not to be lazy, but would running the phone as dual core and limiting it to 1 ghz result in a perceptible battery savings? I'm trying to get a feel for how much I should expect custom ROMs to make my One X perform up to par. Thus far, I've installed two custom ROMs and felt like the improvements were all safely in the minor category.
I did install cyanogenmod 7 on a phone last year wow, that resulted in major benefits.

Running on 2 cores stops the phone from using and 2 cores uses less power then 4, playing games and using all cores is over kill 2 cores will run the game without lag use less power and make less heat.
You'll maybe get 10% from doing that but I haven't tested.
Really the only time any of this saves battery is during demanding programs, tegrea has a super low power companion core, for all your power saving needs.

I tried conservative governor while downloading sd files for Nova3 gave execllent results
I strongly advice not to undervolt tegra3
t3 is not like any other chip and UV or OC should not be attempted
OC because the chip is already at the max of its thermals
UV for the same reason n might end up with problems like flicker
changing governors and UC should be enough
Well the title says it all ,my phone randomly restarts while i am using it since started using arhd so is there any solutions?

i think what i am doing is called underclocking , i am just making max clock speed 1 ghz
that sudden rebooting means you're doing something that crashes your phone... probably the underclocking that causes this.
bit weird though as the hox has many speeds at which it can run, 1ghz being one off them.
Are you sure you didn't also undervolt your hox and that you're using an app that is 100 percent compatible?
Try running the hox at standard speeds to make sure it's not a hardware problem and using an other app to make sure it's not the app causing problems.

strange, but as your not experiencing any problems after uninstalling set CPU it probably has something to do with it... maybe it's a wrong setting / are you sure set CPU is compatible with hox?
Try contacting the programmer of set CPU about this, or try another tool.
undervolting means setting a lower voltage than standard for your hardware, in this case the CPU.
This makes it spend less energy and thus generate less heat. Undervolting can be used as a battery saver (use less energy) just as underclocking.

So, I was wondering if it is possible at all to overclock the Nexus 7 (2013). When I go to the app to overclock it (Yes, already rooted and installed busy box) I am unable to change max CPU's frequency higher than the default 1.5ghz. I also can't change the GPU's frequency over 400. Was wondering if there's like a limit to it or something. I was hoping I could overclock to 2ghz. Please help, thanks

Not to be mean or anything. But you really should not be overclocking your device at all when you don't even know what is required to over clock in the first place'. Let alone 2ghz.

Everybody has to start somewhere.
The kernel linked above should work fine. I would recommend backing up in TWRP/CWM before installing in case something goes wrong.
Why would you need to overclock this device? It already runs amazingly smooth with no lag whatsoever. What is it that you need the overclock for?

On a funny side note, cm11 runs everything lag free without needing oc or custom kernels, so maybe it's the stock kernel that's crap

I am currently using stock rom with elementax kernel, cpu @1,72ghz and gpu @450mhz. When i tried 2ghz oc, everything worked fine, but it got really hot while gaming. So i´m asking me how dangerous it is to use such high oc values in daily life. How much could it decrease the lifespan of the components?

We can only guess. Keep it at 2ghz, and let us know how long from now before your CPU is baked, then we'll all know for future reference.
Also there is an inductive charging coil on the inside for wireless charging some day when they come out with the chargers, sweet ****

Actually it is an underclocked snapdragon 600, but i didn't know that this cpu supports a clock speed until 1.9ghz (thought 1.7ghz would be standard clock). So i think up to 2ghz there shouldn't be any problems and it's okay for everyday use. I've also heard of some rumors that our nexus 7 2013 contains a "second choice" snapdragon 600 chipset, which didn't fullfill the predetermined requirements and that's why it was rebranded as an s4 pro... but this is really unimportant and just speculation.

omg you certainly shouldn't overclock it because the SOC architecture is designed to run at optimal clock speeds... by overclocking it, you might shorten the lifespan of your device and you might even damage it permanently as well

UV is simply "Undervolt", which means reducing the voltage of a component, usually the processor, reducing temperature and cooling requirements. Another benefit of undervolting is conservation of battery power. ExUV is Extremely Undervolted. Some phones cannot simply handle too much undervolting resulting to phone unreliability or reboots.
UV = Undervolt
ExUV = Extreme Undervolt
The phones have some different things, there are some Galaxy Ws with LCD panel rev1, rev2 and rev3. Some GWs get bootloop when the boot is overclocked and some GWs can't work with extreme undervolt, just undervolt.

I want to ask, Undervolt means underclock?
Hi guys,
I understand that some heat when running resource intensive applications and games is to be expected but I believe I've passed into the danger zone, so to speak. When playing XCOM my CPU temperature quickly exceeds 80°C. From my googling on the matter I have come to assume that a temperature as high as 80°C is dangerous for the hardware of the device, but I have had trouble finding upper threshold limits for the model itself.
I guess my questions are as follows:
1) How damaging would running the CPU at 80°C for an extended duration (1hr +) be?
2) What would you consider the max acceptable CPU temperature to be?
3) Assuming it is as bad as thought, what are my options to reduce the CPU temperature, short of avoiding the problem applications? Underclocking seems to be a common suggestion, but I get the feeling that XCOM, or similarly taxing applications, may just fail to run or become incredible sluggish under such constraints.
My device is rooted and running Lean Kernel v2.4 along with the w03Slim ROM. Found here: http://forum.xda-developers.com/showthread.php?t=2638116
I've done similar test runs in the Temasek kernel with the recommended configurations through Trickster Mod and there is no difference, the CPU still exceeds 80°C when playing XCOM. After a week or so of googling, searching the forums, and digging through device manuals I feel like I'm spinning my wheels.
Any insight or advice you all might have is greatly appreciated.
Solved!

Agree with this post, conservativex is a great governor to keep your cpu in check and not over throttle itself, also check out my thread I made here awhile back and apply the 8th post down. It really helped keep the temp down on my phone when playing graphically intensive games like dead trigger 2,riptide gp2 etc. Also if you have trickster mod or faux clock(really recommended) you can scale down your max frequency, that should really help keep it cooler and you won't see much of a performance drop (if any) while gaming or heavily using your phone.
