i am running cm7 with stock kernal i go into settings then to cyanogen settings then to cpu settings the min. i can do is 245 mhz and max i can do is 1113mhz and it was set to 998 mhz what would be a good setting to set the max at for better battery if able and also not have bad performance?
all of the options are:
245 mhz
384 mhz
422 mhz
460 mhz
499 mhz
537 mhz
576 mhz
614 mhz
652 mhz
691 mhz
729 mhz
768 mhz
806 mhz
844 mhz
883 mhz
921 mhz
960 mhz
998 mhz
1036 mhz
1075 mhz
1113 mhz
I would just leave it at 998. You really don't notice that much of an extra boost by overclocking IMO. You can underclock, I had mine at 768 and didn't notice any slowdown, but can't say it helped battery life tremendously. Try out what you want and take note of your findings. See what combination works best for you.
Defaults are actually pretty good. However if you want to increase your battery life look at some of the other kernels out there. I've choosen Chad's incredikernel. It charges up very fast and has a min CPU of 128 which improves the battery life when the screen is off.

yeah i have the incredikernal on my computer ready to put on my SD card cause ive seen pretty much everything good about that one but then i also see everyone saying that kernals dont really show a difference.. i guess my only option to do is try it out and see where it takes me...

thanks for the reply and yes thats what im going to do
the latest one from cm7 gives me a great battery life
+1 for Chads.
anything with the smartass gov. rocks imo.
So I installed the Perseus kernel and with Stweaks I overclocked the CPU at 1800Mhz.
Antatu = over 19000 points
Then I oced the GPU only to 800Mhz = 18400 Points
But when I decide to overclock both at maximum (1800/800Mhz) I get low score.
Even overclocking the CPU @ 800Mhz and CPU @ 1700Mhz = lower score than just CPU @ 1800Mhz
Is it because the CPU is throttling? What's wrong?
Dear cyber.bg,
Yes probably your cpu is throttling to 800 mhz from 1800 mhz because it reaches the temp of 80c...
To avoid throttling, you have to undervolt cpu when overclocking...
According to me , overclocking gpu over 533 is useless and also makes a lot of heat which push cpu to throttle ... Even gpu @640 mhz with higher voltages you will face freezes and lags...
So just overclock your cpu to 1800 mhz but with lower voltages... Most note 2 cpus can do 1800 mhz @ 1250mV... You can try to give -25 to other values from 1250 mV... 200 mhz @ 775 mv is also fine and no deep sleeps for me.
Dont overclock your gpu but you can undervolt it a little bit... gpu @533 is fine with 1050 mV...
With the right frequency and voltages for both cpu and gpu there will be no throttling so u can get real antutu scores... cpu @1800 and [email protected] with lower voltages, u can expect an antutu score between 19300 and 19800 depending on your rom, kernel and tweaks...
You can use stweaks app to overclock and undervolt...
You can use system tuner pro app to observe cpu temp and other data...
Hope all these helps...
Kind regards.

Thank you for your reply, it was very informative
Currently I am with Note2Core AS (the 1.92Ghz kernel) and I still have the throttling problem, even though my CPU temp doesn't go beyond 50C in Quadrant. But it is till throttling.
I've tried to edit voltage with SetCPU, Voltage Control Extreme and System Tuner Pro, but they don't stick - they just revert back to their original values (1425mV for 1.92Ghz) Stweaks says Sorry, no kernel support.
The interesting part is that in the beginning I managed to run 1-2 benchmarks without Throttling, but anything after that is throttled. Best scores so far:
Antutu: 19868
Quadrant - 7941
Do you know why I can't edit voltages and why it throttles even when CPU temperature is low?
Maybe it has to be plugged in and charging from the Wall?
Dear cyber.bg,
I am using perseus v29.1 kernel and it supports stweaks app... Also i can use voltage control or setcpu with this kernel but i prefer stweak since it has native support in the kernel.
First, 1.9 mhz @1425 mV is really high and thats why your cpu throttles...
I do max 1.8 mhz @ 1250 mV to avoid throttling... I did many test and voltages above 1250-1300 will bring throttling back. My cpu is stable @1250mV...
With quadrant cpu may not throttle because it is an outdated benchmark and i am sure it doesnt use all the cpu cores @100 percent...
Antutu is the solution to observe for throttling...
To observe temps and throttling, run both antutu and sytem tuner pro in split view...
Also i use a 4k video to push all the cpus to max and view video in floating windows so u can see all the data in system tuner pro while video is playing in floating window.
Lastly, my advice is dont go over 1.8 mhz @1250 mV for cpu and 533 mhz @1050mV for gpu... i am sure with these settings, u will have a stable note2 with no throttling and at its max performance...
Hope all these helps...
Kind regards.

Thank you again for this very knowledgeable post
I've used Perseus too. I even switch them daily while experimenting.
I put the Note2Core because I want to push the phone to its limits and get a really high benchmark scores. I've seen people reaching almost 9000 in Quadrant. And for Antutu I already got a really high score (19548), but if I manage to stabilize it at 1920Mhz I can get higher. But it throttles
And I still can't understand why it throttles? Some people say it's because of the high temperature, but how high is high? When I finish with a benchmark and go to look for the temp the highest I've seen is 50C. Is that high?
Also how do I run Antutu and System Tuner Pro in dual view? Their icons are not in the side menu that I open when holding the back button. How do I put them there?
Have you tested with more than 1800Mhz for the CPU? or more than 533Mhz for the GPU only? Can you post some Quadrant and Antutu screenshots so I can compare.
Thank you again
Dear cyber.bg,
Here is my antutu and quadrant results...
Wanamlite v2.1
Perseus v29.1
Cpu 1.8 mhz @1250mV
Gpu 533 mhz @ 1050 mV
Antutu ~19300
Quadrant ~7300
I have run both antutu and quadrant only one time...
By the way, cpu begins throttling when its temp reaches 80c so i am sure you hit this limit...
I have also tried 1920 and 2000 mhz with angelom kernel but because of throttling and so much heat, i had to return back to 1800 mhz with perseus kernel...
Kind regards.

2 questions:
1 - How can I see the maximum temp the CPU reaches?
2 - Did you have any successful test at 1920 and 2000 mhz without throttling?

Dear cyber.bg,
1- The only way AFAIK is to use system tuner pro app... Be aware that apps like setcpu reports the BATTERY TEMP not the CPU TEMP...
2- Unfortunately NO since these speeds need min 1400 mV to be stable but throttling occurs immediately so no meaning to overclock...
Steps to observe throttling...
1- Download and install system tuner pro...
2- Download and install super video app and set it for software decoding not hardware decoding.
3- Grap a 4k video (life in the garden) from you tube with the tube mate app... i use this 4k video because it pushes all the cores to max with nearly full load in software decoding mode...
3a- Alternatively you can use antutu and system tuner pro app in split view to observe data... You have to flash this mod in able to add these app to multi windows list... http://forum.xda-developers.com/showthread.php?t=1953705
4- Play 4k video with super video app in a floating window...
5- While video is playing run system tuner pro app and touch to cpu button...
6- Now u should be able to see cpu data like temp,core speeds,load and also video in floating window all together
7- Observe the cpu temp and core speed... if the temp reaches 80c then core speeds down to 800 mhz which mean cpu is throttling... Try to undervolt some more to keep cpu under 80c but with stability of course...
As i said before, the max i can go without throttling is cpu 1800 [email protected] mV and gpu 533 mhz @1050mV... With these settings i can maintain stability, and full benefit from overclocking without throttling...
Hope all these helps...
Kind regards.

I tried 1800Mhz @ 1200mV and it seemded stable. GPU was 533Mhz @ 1050mV
You also write that it starts to throttle at 80C - have you found out that yourself or it is in the specifications of the chip?
Here are 2 shots (these were before I tried lower voltages):
Samsung Galaxy Note 2 - Jelly Bean 4.1.1
Quadrant (Run Full Benchmark):
Note2Core Kernel
CPU: 1920Mhz, 1425mV
GPU: 533Mhz, 1050mV

GPU: 533Mhz, 1050mV
Geekbench 2:
Note2Core Kernel
CPU: 1920Mhz, 1425mV
GPU: 533Mhz, 1050mV
Dear cyber.bg,
Nice scores... Well done... Which rom ?
During my observations with system tuner pro, i have realized the throttling temp is 80c..
I think the throttling level can be configured via kernel so this is up to the kernel developers... i remember from note1 that there was thor kernel and with this kernel cpu was throttling @85c and to 1.4 ghz not 800 mhz if i am not wrong...
Kind regards.

Scores were with stock 4.1.1. I haven't installed any modified ROMs so far, cause I like the stock
Btw I'm afraid to use System Tuner Pro now, because last time I tried to uninstall it my phone froze, but I pressed the power button for 5 seconds and restarted. On the 2nd attempt to uninstall it the same thing happened, but after restarting the OS didn't want to load. I didn't have a backup or anything and had to reinstall everything. At least I put 4.1.2, so I'm making a Nandroid backup through CWM recovery now. That was a good lesson.
Have you tried 1.8Ghz @ 1200mV for daily use?
Dear cyber.bg,
Yes, i tried 1.8 @ 1200mV but i got frezees while playing some 2k and 4k videos so i decided to be safe and push it to 1250 mV even 1225 mV seemes stable for my cpu...

Tegrak Overclock Ultimate is amazing !
I also noticed tegrak's overclocking doesn't take effect until I open Setcpu..
Edit: Overclocked to 2gHz @ 1437 volts.. what is the repercussions to the volts being "too high?"

Hi PROTOCHIP,
Can you send image files of your's STweaks settings? (for oc and for battery life)
Your experience is so reliable.
Thanks a lot.
Why can't I see any difference between the 533Mhz GPU and 800Mhz GPU on the GLBenchmark? I don't OC the CPU, I even tried to lock it to 1200Mhz to avoid thermal problems however I couldn't reach above 18 FPS in Egypt test. Normally it is 17, with 600 or 700Mhz it goes to 18 and then stays there.
When I compare the GPUs of the SGS3 and Note 2 there is %10 overclock on the Note 2 side and the results exactly indicates this. SGS3 scores 15 FPS, Note 2 scores 17 apprx %10 higher. From this comparison i take it as the results are linear with the clock speeds. I was also proving this theory by OCing the Note 1 to 400 Mhz and reacing a few FPS below SGS3 on GLBenchmark. So, without any problem Note 2 should score 30-31 FPS on 800 Mhz but that is not the case in real life. So I guess it is either never goes to 800 Mhz or thermal throttling happens during the test. Orrrr, maybe 1080p offscreen is not a good option to push-test our Mali-400s? But there is no other GPU benchmarks to push our devices like offscreen because of the 60 FPS lock.
What do you think about this? Is it possible to reach the 30 FPS level?
Can you guys tell if this is ok? Or can I still go lower.. I just eant fair speed with battery saving..
Thanks in advance

Dear _delice_doluca_,
Same here and never had the chance to go over 18 fps with my note2 too... Overclocking over 533 doesnt help because of gpu throttling... In theory as you stated , we should go over 30 fps easily but in reality, this seems so far...

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 se 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've been noticing my Gnex battery has been overheating not even with heavy usage. I'm talking about mild web browsing on 3G, in about 5 minutes the battery would skyrocket to about 45 - 50c easily. I'd like to share with you my UV Settings/ Kernel that reduced the temperatures . With the settings below my device hasn't overheated, not even while I charging and putting heave use it on it!

Regardless of UV'ing and underclocking, the phone is still going to produce some heat. It's the TI-OMAP and it's terrible cooling efficiency. Newer processors on the market right now such as the Snapdragon CPU's are absolutely great at keeping the CPU cool even at high load. Not to mention they're more battery efficient and can be overclocked to oblivion!
You know this phone runs much cooler than my sgs2 which has a snapdragon s3 (also a 2011 device). You could probably cook food on that device when it is under heavy network load.

You should monitor your CPU temp and frequency while benching.
You would see that your CPU's temp probably goes above 70°C if not higher and so the kernel thermal throttling policies would downclock your CPU's max freq. in order to keep your CPU "cool".
If you first bench @ 1944MHz then bench @ a litle lower frequency and have very lower score then its not because of the lower freq. but because you did first heat up your CPU @ 1944 and when you re-run @ lower freq. your CPU is already very hot and so does a severe thermal throttling.
Last point : running your CPU @ 1944MHz is not good since thermal throttling while happen every now and then.
Not convinced?
Then simply launch the camera app and try to take a video of 5 mins...your CPU will become so hot that it will downclock to something ridiculously low and your recording will become jerky.
Hey was wondering if anyone knows off by hand the lowest we can undervolt our phones @ stock freq or what our stock voltages are? I undervolted mine recently and got amazing results but stability seems to vary, using overclock freqs @ 1.89 running @ 1.087 mv 1.83 @ 1.05mv 1.78 @ 1.0375 1.7 @ 1.025 mv I seem to be fully stable pulling 28905 scores on anutu, my friends s4 isn't even this fast was very impressed phones not even hot at all, but I really want to try to tweak the lower freq to help with battery life/temp
solution to the battery drain problem
Overclocking the CPU frequency will lead to battery drain as u know it yourself....don't download any of the battery savers as they are useless .....try Greenify....bcoz it works....and it just is too awesome.....
Undervolted and got these results with anutu, impressive, looks like undervolting gets good results
Stock Speeds 1.7ghz -> 1.050
Barely over Stock 1.78ghz -> 1.075
Mild overclock 1.836ghz -> 1.0875
Higher overclock 1.89ghz -> 1.100 (highest anutu score)
Pushing it 1.944 ghz -> 1.250 (yielded a score the same as 1.89ghz)
what kernel were you using here and ROM? thanks
