You can use any custom overclocked kernel from forum and set cpu clocking frequency to stock i.e 2.1 ghz and overclock gpu frequency as per your need using kernel adiutor app. You may find app link on custom kernel thread page.

Over clocking will always produce more heating. Usually Custom Kernel which allows OC comes with tweaks to thermal management to counter that as much as possible.

[Q] Overclocking GPU?

Hi,
Sorry if this has been posted before but I can't find an answer to this question
I am currently running AOKP and trinity kernel, 1344mhz (cpu) and 499mhz (gpu). After installing the kernel, I manually went into ROM control, and increased the CPU to 1344mhz - set on boot. That was the CPU overclocked
However, I can't figure out how to overclock the GPU? I have run a benchmark, and it seems to still be at stock, and not 499mhz - how do I set it to the 499mhz that the kernel allows?
Thanks

There is a command that you can run from terminal on your phone but I can't think of it right now. Also, a bit of searching seems that there is an app. I haven't tested to see if it works, but it says it OCs the CPU AND GPU. Look for Overclocking(GPU + CPU) in google.

That one apparently doesn't work.. have also tried Antutu CPU Master pro but it doesn't support GPU overclocking on the Galaxy Nexus...
Afaik, gpu oc is only available, if built-in the kernel. Userland controlled gpu oc must be supported by the kernel first, thats probably why antutu pro master or any other app still can't do it.

KISS-Kernel

excuse me; have question about this kernel; i couldn't post in the original thread;
by setting the min clock speed to 768MHZ & the max to 1407MHZ, How much voltage does it spend? by setting the min to 245MHZ & max to 1024MHZ how much? i overclocked to 1407MHZ , i saw more smoothness and speed; but i felt that its consuming more power!
is overclocking harmful to CPU? ( always overclocking )
Rom: MY One V RC4.0 FX
PrimoU GSM
Kernel: Latest Kiss Kernel
Hi
Political correct answer:
Of course OC "can" harm your device - like all OC´ing
Realistic answer:
Most One V devices can handle OCing up to 1.5 without problems
but since this may be specific to chip manifacturing there is no
guarantee that it is. Therefore before using any OC you should
test it very carefully.
And also - Of course running the chip at higher frequencies needs
more power. Simply physics .)
In "normal" daily use the difference is not big because the cpu will
not run at high frequencies most of the time. If you do things
like "heavy" gaming this is of course forcing the cpu to run faster.
To reduce the "effect" a little bit there is a kernel feature called
Undervolting (UV) with that you can reduce the voltage for
specific frequencies. Like OC this is device specific. So some
devices can run stable with more reduced voltage then others
BTW: why to you set the min frequency to 768?
This will limit that the frequency cannot go lower then that if the
device is idle. Running at 245 needs of course less power then 768
max
Thanks for the nice info, well, i heard that some users said that the best frequency for " My One V" rom:
Minimum: 768MHZ
MAX: 1407
I'm using "Set CPU" to OC
So setting the min frequency to 245MHZ will save more power, right?

Yes - especially for the time before the device can go into
"deep sleep" when beeing idle.
The only "disadvantage" is that depending on the govener that you use
there might be a small lag before the frequency scales up
Actually it depends if you notice it at all
If you use govener ondemand it should be no problem
if you use e.g. smartassV2 you might consider thinking about
using some tunables that will reduce that behaviour.

Thanks, yeah, i meant for normal activities, like checking Facebook,mail, watching movies ... So ondemand mode would be better

What is your recommend governor to integrate with your Titanium-KISS kernel and what is your favourite I/O Scheduler tweaks, for daily use & heavy gaming?
I'm using smartassV2 & i set my I/O Scheduler to deadline until now, because it's peoples favourite
Should i change it to ondemmand to gain a better performance?
Hi
Actually there is already a lot of information about your question
in the KISS kernel thread.
Especially about how to tweak smartassV2 based on "profiles"

Stock GNex voltages

Hello,can someone please help me by telling me the stock voltages for the CPU,GPU and IVA? I have freezes with the basic voltages in franco's kernel SmartReflexand enabled.
I saw that some voltages from the CPU are decreased from the stock ones. I think my phone can't handle those voltages(maybe something chip-related) and I want the stock voltages and franco's kernel tweaks too
Im on AOKP milestone 1 (4.1.2) and franco's r300 kernel.

Up the voltages yourself until device is stable. And its indeed related to your chip quality.

I just disabled the SmartReflex option in franco's kerenel and my device is working like it never did,hope it will remain like this )

I thought you knew the stock voltages, seeing how you mentioned that franco's voltages are decreased
Anyway here it is.

those are exactly the ones that I knew,i need for the CORE and IVA :-/
I dont think franco's messed around with core and iva, only cpu voltages.

I overvolted each freq in CORE with about 50 mV and the games that use to have many little freezes,now they don't i probably need to overvokt IVA aswell. The only thing that slutters now is when watching a video,and sometines when scrolling thru desktop pages and appdrawer pages.
That's what i said.

[Noob Guide] What is and How to Undervolt

Hello, i wanna share my experience undervolting.
For people who dont know what undervolting is, its the power or energy that the battery send to the CPU with determinate clock speed.
For example:
384 Mhz is the lowest frequency of our CPU, it has a 800mv volt in the stock ROM with stock kernel.
So in theory, the battery send 800mv to the CPU when it runs at 384 Mhz.
The effect of undervolt the CPU is bassically get more battery life and at the same time reduce the temperature of the phone.Less energy send less battery used and less hot phone in our hands.
How to Undervolt
Im running Stock ROM with Ruby Kernel stable.
For undervolt you need a kernel that support it, you can do it in all rom if the kernel support that.
If you want to Undervolt, i recommend you to use Trickster MOD.
You can Undervolt maybe -50mv all frequencies and see how it goes. Some people can even in best cases undervolt -200 mv. But you need patience to test slowly.
DONT TICK SET AT BOOT IF NOT TESTED.
That why you cant:
For example if you undervolt -100mv and if not stable, and you have set at boot ticked, it will freeze the screen and after reboot it will happen again.
After you set the mv for undervolt, download from play store CPU stability test and run it.
It will test all CPU frequencies to see if it is stable.
If you dont get any SoD, congratulations its stable.
My undervolt settings are -100 or in some cases -75 mv and very stable. My battery temp is 30 C°.
Thank you very much

What is needed to undervolt?
Thanks for the info. What are your battery stats after undervolting? How does it suffer other operations of our mobile like browsing or gaming etc ?
Sent from my LG-E975 using xda app-developers app
You need to first make a backup, install a custom kernel, install trickster mod, and from there apply what this discussion is talking about. Good luck!

Bootloader unlocked with freegee and some kernel for your rom that supports undervolt.

Depends on the kernel. I am using Trickster Mod with Viper ZVC kernel. There are other control apps available -- some of them are kernel-specific, some are more universal (Kernel Tuner, Android Tuner, System Tuner, etc.). Look in your kernel's thread -- the developer usually tells which control app(s) to use with it.

Thank you, I'm using AK kernel with UKM and Synapse app from google playstore. Using E-975 (intl.). Can you suggest if I should change the global setting or the individual settings for frequencies ? I had recently (soft) bricked my phone by running benchmark at ~1900mhz CPU and 487mhz GPU (like a villain, I know. Re-connected battery to save it... phew..). I'm really cautious now and I just want it to be less hot and save some battery, that's all. Any guidance would be really appreciated... thanks

[Q] Add custom CPU Frequencies to Kernel

Hi there
Is there any solution to add custom CPU frequencies to the kernel?
As the ElementalX Q port is locked up to 1512Mhz
I remember the original version can push up to 1.9Ghz something
Any solutions?
BUMP
we really need it, For good work on a12.1
But here you only need a custom kernel with a set of these frequencies. No way to add on your own (
also it would be nice to increase the frequency of the GPU
GPU can be overclocked to 550mhz. Just CPU is locked down. pity!
