I've noticed that the default clock speed for the Nexus 4 CPU is 1GHz - 1.2 GHz (for my phone, anyway), but any attempts to underclock either of these values with many of the available CPU control apps have been useless, for after about a minute of usage, the clock speeds return to default, despite the CPU governor remaining as my choice.
I'm wondering if it's actually possible to effectively underclock/overclock on a stock ROM. If not, are there any battery-life optimized roms/kernels out there?

Are you rooted? If you are, I don't think you should have trouble underclocking on stock. What app are you using to change your CPU frequencies? Try using a different one.
Trinity Four kernel has given me the best battery life so far.

You need to be rooted, use setCPU (app) or flash a custom rom
Can I flash the Trinity Four kernel over the stock ROM without having to wipe everything?

Hi all,
I am using a rooted n7.
I have over clocked my galaxy s2 to 1.5ghz before, but I am not sure what is a safe level to over clock the n7 to.
What is a is is for battery life and performance?
And which kernel do u guys recommend
?
Thanks in advance
Cheers

I run trinity kernel on my Gnex and N7 and on my N7 I keep it stock speeds because I've seen no reason to realistically OC it. Most of the improvements I see are from the kernel software changes over stock. You can OC to 1.6 safely but I'm not sure of the power usage difference but I'm pretty sure the loss in power isn't worth the gain from OCing.

I have mine at 1.6 just for the hell of it, I get a good 4 or 5 hours of continuous usage out of it.

For the benefit of the community, can you tell us any major changes at 1.6 GHz?
Is there anything noticeably faster?
Hi, I have a related question but can't post since I'm new.
Using the glazed rom which i like but it apparently has gpu overclock. I would like to know how to adjust that back to stock setting or at least see what it currently is. I found the CPU section but there is no gpu I can see.
Is there a tool I can use?
Sorry for the hijack...at least its sort of on topic
IMO over clocking is a gimmick, its the kernel build

My thoughts exactly. I play some light games and web browse on my Nexus 7.
For those purposes, my Nexus 7 is already extremely fast, so I don't think I would be able to notice if it was over clocked.
But I guess it depends, maybe there's a big difference when running GPU heavy games.
I have OC mine upto 1640 MHz for bench marking alone for half and hour or probably more and it went fine although the tablet was getting warmer more than usual.

Hi,
I decided to flash trinity kernel.
I am currently OC to 1.5yghz, is that a safe level to keep it at full time? Or can that burn the cpu out?
Thanks again
Cheers
Corey
Edit,
I over clocked my galaxy s2 ages ago, and I noticed a huge difference in performance.
So that is why I want to over clock my n7 too lol

there is no such thing as a safe overclock. overclocking, by nature, carries some risk. that said, i havent seen anyone brick their device from overclocking.

Just wondering
Why do you feel the need to OC?
I go to 1.6 but use the Trinity App to go back to stock when OC not needed
Sent from my GT-I9300 using xda app-developers app
I have not over clocked the Nexus 7 yet but one way to test your devices max is to use setcpu. Make sure you do not have "set on boot" option selected. Then step up your cpu. If your cpu can not handle the over clock it will force restart. If you do not have the set at boot selected it will revert back to the last good state on restart.
Each device is different on what it can handle for over clock.

To be honest I doubt you'll notice much increase from oc the CPU since the CPU already is so powerful nothing pushes it to max really.
Only thing worth overclocking is GPU really. And at that, your not going to notice a difference unless your playing some intense games.
Hi all,
My Nexus 7 is fastboot unlocked and rooted.
Is it possible to underclock Nexus 7 without using custom rom?
I read about SetCPU app, does it work properly with Nexus 7?
I was thinking to underclock to 1.0 ghz in order to gain more battery life.
Please share your opinion if you have done it.
Thanks

Underclocking wont make that much of a different. You can undervolt it (same speed less volts being used)

Wasn't the primary reason google underclocked this tablet was to save battery?

Did you solve your issue somehow?
I want my max clock at 1 GHz too to save more battery.
You don't need a custom ROM; only a custom kernel. You can probably use SetCPU or whatever app the dev recommends. But as the above user said, you could undervolt instead. If you stay at 1.3 GHz but you use the voltage for 1.0 GHz, you will save the same amount of power (if those settings are even stable...) as underclocking it.
Hey guys, I'm new to the forums and fairly new to Hacking and overclocking android devices. However I have been building and overclocking high end PC's for sometime. So I am no stranger to the risks or processes of overclocking.
But I have some questions that maybe you all can help me out with before I start overclocking my Nexus 7.
Here are my Current Specs and Software:
Nexus 7 Wi-fi version
SmoothRom v5.0 + LeanKernel
Currently I am overclocked to 1500 Mhz Max with 204 Mhz Min + Stock voltage
I have been able to find information about CPU overclocking. But after extensive searching I have not been able to find much on Nexus 7 GPU overclocking.
1. Does my kernel support GPU overclocking?
2. If so how do I enable it? Or where is it located? and what settings should I be looking for (Names)?
3. If you need an App to overclock the GPU are there any that are free (Or at least one worth paying for?).... and which one if any supports my kernel?
4. Are there any good Nexus 7 CPU and GPU overclocking guides someone could point me to?
Basically I am looking for someone who is experienced in Nexus 7 overclocking, to point me in the right direction and help me with some indepth questions that may come up.
Thanks guys
What temperature is your CPU?

According to System tweaks App 39c to 40c while idling in that program. I don't know how accurate that app is though.... so if there is a standard better app to monitor your CPU/GPU temps I am all ears
I have yet to find an app that allows you to monitor your temps during load. Again if you can suggest one I am all for it.
Try trickstermod

Alright I will check that out. But what about GPU clock settings can trickster change those too??? And if so.... What setting am I looking for because I saw nothing referencing GPU clocks in those words
Sent from my Nexus 7 using xda app-developers app
It over clocks the GPU its on the 2nd to last page I think and you will see the clock speed and you can edit it, don't over kill though haha
Sent from my Nexus 7 using xda premium
Lean kernel doesn't have GPU over clocking settings. Try M-kernel, you'll find gpu settings in the specific menu of trickster mod.
Feel free to share your setups and experiences in this thread.

I'll start things off for you...
It all depends on what you want out of your phone. My set up is for battery performance so I've got omega rom v3.1 teamed up with kt-sgs4 kernel. Under volted by 50 across the board, under clocked when screen off and some smaller tweaks to help eek more battery out...
After full day of use with wifi, bluetooth, gps and air gestures on I've still got 48% battery left...
But equally u could use the same set up for performance if needed by changing some kernel tweaks like screen off mhz, Overclocked cpu and gpu etc etc

What's the best recovery?
I could give you a link to the one that works best for me but it'll probably brick your phone.
