Kernel that is only undervolted but not overclocked?

Can someone post a link to a kernel that runs at the stock 1.5ghz but is undervolted? I don't care about performance. Just want the best battery life. Thanks!!

Almost any kernal is better in battery than stock

you can easily limit the CPU to not go over 1.5 or even 1.0
when i really want to save battery i keep CPU at 800 Mhz or 1.0 Ghz

Any of the kernels in the development section can be either under bolted or over clocked. I'm using synergy the way it comes out of the box and its great. Standby battery drain is unbelievable.

why dont u UV ur 1.5ghz to 1.0ghz voltage? or near there?

That would be underclocking not under volting

in CM ROMs it's build in
in other ROMs you can use SetCPU or faux or the other one i forgot the name right now

true, but i find it more effective than UV
yes, we can keep it at 1.5 Ghz with say -0.010v or something like that
it's just a minor hassle to tweak
you can open a Terminal in your phone and launch the command
some apps like the faux can let you control the voltage as well

CPU Overclocking

Anyone has managed to overclock the cpu of Samsung Galaxy W?
I've tried with both SetCPU and CPU Master with no results, as the max frequency cannot be increased more than the default speed of 1400MHz..

For overclocking need custom kernel

Correct!!
Arco is working on a custom kernel, and maybe i will give it a shot if there is a good tutorial!

gr8! thx guyz

I've talked about this before.
Arco refuses to add higher speed frequencies to his kernel before making sure it's stable and smooth.

I see, can you tell me which file should I edit to add higher frequency on the kernel source? (just for experiment)

CM 10 Clock Speed

So I have recently installed CM 10 on my S3 and I'm loving it. However i am a bit worried. The S3 is said to run at 1400 Mhz or 1.4 Ghz. But when I go into settings then performance, the max is set to 1512 Mhz and I didn't touch anything! CM sets it to this by default. My question is does Cyanogenmod overclock your device? Or is that the clock speed that S3 really runs on? My phone has also been getting hot lately but I'm not sure if that has to do with anything at all. Any help is Greatly appreciated!!!

If the kernel supports it. But stock touchwiz runs at 1.5.

I never changed the kernel. So I shouldn't worry right?

1400 mhz is the max stock clock frequency on the international version (i9300) and 1512 mhz is the stock max freq for the at&t version (i747).
I haven't had any issues with heat. Try running an app to check the CPU temp.

Also how is or battery life? I know when my phone gets hot its because something is eating my battery. I by some controls on said apps and I am running at 1.9 with ko heat issues

The battery life is great I'm not sure why its getting hot

I would use better battery stats just to see what is accessing or CPU. Also u may wipe and do a fresh full clean install. Like I said I have mine over clocked to 1.9 with no undervolting with no issue. But also keep in mind every phone is different.

Any GPU Overclocking Kernels for...

I recently flashed the KT747 for a super fast 2.1mHz CPU overclock. But then after flashing I realized it doesn't overclock the GPU that much.
Are there any kernels that can overclock the GPU to about 700mHz?
-Thanks for any help!

Sorry for CyanogenMod 10.1 (d2att) nightly ROM.
Does the new SiyahKernel work with the ATT Galaxy S3 running CM10.1 nightly?

Ah stupid me I meant 2.1ghz or 2106mHz CPU overclock.

I don't think any kernels do GPU OC, because it has shown to cause more problems than it is worth. That's just what I remember KT saying.
Sent from my SGH-I747 using xda premium

Most custom kernels if not all already have GPU OCd to 450mhz
Over clocking the GPU on a GS3 is not needed and even with it over clocked, you wouldn't tell the difference. It also leads to issues and battery drainage.
The S3 doesn't need OC at all 1.2Gz with 2Gz of ram leaves no place for lag.

Then how come when I play high quality games they lag so much on all qualities.

I haven't had any lag whatsoever at any point that I've had my S3. Try reflashing your rom and completely wiping. Also try a different kernel and kernel settings.
This phone shouldn't lag at all. Maybe a little on TouchWiz but never on AOSP

My s3 lags at 2.1 GHz too. Try it at 1.6 or 1.7 GHz or change governor settings to a faster ramp up one.

Best Kernel for Overclocking Galaxy Nexus

I'm thinking of flashing a different kernel to my Samsung Galaxy Nexus so I can overclock the CPU/GPU. I've noticed that franco.Kernel and Trinity seem to be among the most popular kernels, but I'm not sure which one to choose. In your opinion, what is the best kernel for overclocking and why? FWIW, I have the Verizon model of the phone (toro) and am currently running CyanongenMod 4.1.2, which is based off of Android 4.2.2.

Try It And See. TIAS.. GlaDOS kernel can overclock to 2.0 GHz.. The highest I ever saw. But my phone didn't like it. As for the rest you just have to try and see which kernel suits you best.

Antutu or CF bench are good apps.. And a warning: overclocking will decrease the life of your phone! Be careful! If you want to use your phone a little longer I wouldn't do it (I wouldn't anyway because I think this phone is very fast especially with Android 4.3)..

Hi,
I've decided to bump this thread because all other GNex OC threads are very dated.
I recently received the extended battery 200mah and I'm ready to overclock. I wish to retain battery life to have screen time 3-4 hour on moderate usage.
I'm current rooted on stock ROM, and I wish to simply stay with stock ROM provided battery life will remain the same (perhaps I have to undervolt)
I want to hit 1.5GHz CPU and 384MHz GPU...which is what the OMAP and PowerVR SoC's true default clocks.
Given my circumstances of stock ROM, which kernel would give me the best stability/battery life? Any kernel that somehow has OC settings built in or do they all require me to buy setCPU?

They all use setcpu or trickster mod. Regarding the kernel you just should try some out.

What type of OC are you running?
Do you actually notice it day to day usage? I cant think of any apps that could benefit from it besides gaming which I do very little of on mobile.
How has it affected your battery life?

I don't OC myself. I want my gnex to last some longer. OC will wear out tour CPU.. I die it once for a day maybe two but didn't notice any improvement. I was at 1.5 GHz or something.. I think it may have some speed improvements but your battery will drain like a maniac. If you don't game I suggest you underclock: even more battery life with no speed loss!!
