Hello all,
I've a question since some day, I try to find the answer with search but with no success.
Which benefit you can receive with UV or OV?
I think that:
The UV is better for battery life but with less performance.
The OV give a better performance but consume more battery.
If so... why you find many overclock setup with more Mhz but less Volts?
I cannot understand that... it's look like a no sense for me.
I've a Galaxy S with NEO 17 Kernel.
Actually use:
Governor: conservative
Force Minimal freq when screen off: OFF
1200 Mhz -25
1000 Mhz -50
800 Mhz -50
400 Mhz -50
200 Mhz -75
100 Mhz -100
I try this setup coping from other post, because I want the better life battery for "office use" but a good performance when I do gaming... but I cannot understad why of this setting
PS: sorry for my poor english.

How come you think that UV means "less performance"? Core voltage has nothing to do with performance (at least not in the way, you mentioned it)
I think you can found some good tutorials about OC/UV, somewhere in sgs section..so check those out to learn more about this subject.
It isn't always very easy to figure out these things, but it's good that everybody can found lots of information from xda

First of all thanks for your reply.
I "suppose" that under voltage is mean less performance, but I really don't konw.
I want to understand why I have the possibility to under or over voltage and what does mean...
In order to make an example, which different are there if I put 1.200 Mhz with voltage -50 or 1.200 Mhz with +100 voltage?
Sorry I'm newbe in overclocking!
I was using oc for few days and I didnt find a better performance except the quadrant score. Anyway oc is a risk process. If we are not getting that much performance then why should we take risk. Try Darky ROM v10.2RE and flash semaphore kernel you will get a better performance without OC.

Using in ROM http://forum.xda-developers.com/showthread.php?t=2386561 and so far did not show any apparent bug. Very fluid system. No overheating, lags and crashes. Let's wait a few more days. But congratulations on the good work.
fashed the kernel and so far so good everythig is ok. if its not to much to ask for a request. please in ur next release please add slide2wake function and sound boost like in dorimanx kernel.

It would also be extra handy if your next kernel iteration could be able to prepare delicious meals, automagically disconnect when my ex-wipe™ calls and bark at postmen when they enter my front yard. Please consider including these useful futures®, I'd much appreciate it.
OK so after a few hours of testing, the phone is not heating up at all and its very fast and fluid but the battery runs down too quickly, lost 3 percent in time it took me to type this. I'll test how well it sleeps next and report back
welcome!!!
I am impressed with this kernel!
So snappy, smooth, cold and lets see the battery now...

Thanks everybody !
I will release two undervolted test builds (CPU and GPU) as soon as I can. CPU will only affect group B as I can't test for group A and C.
I do not intend to add some fancy features or overclocking to this kernel. I'm trying to make simple changes that have a real impact.
Remember : the main bottleneck of the Note is in userspace, not the kernel. The latest Insignal source drop may improve a lot the smoothness of our device. It is not merged yet into CyanogenMod, as it requires some big changes, but it will come some day. Crossing fingers.
I'm waiting for some more feedback...

Good work!
Currently testing cm10.2. Will try this kernel tomorrow with the latest cm10.1 build.
CPU undervolting test build.
Here's the hardcoded voltage table I'm using (only for group B), based on my own tests :
Code:
MHz mV crash nominal delta
1400 1200 1125 1300 100
1200 1100 1025 1225 125
1000 1000 950 1125 125
800 900 850 1050 150
500 875 825 950 75
200 850 775 950 100
Download : raw_kernel_r1_cpu.zip
This is a TEST BUILD so it may be UNSTABLE. Report any problem but don't complain.

Im on a volt group B.
The most stable undervolt I use from ICS to JB is:
MHZ----------VOLT
1400---------1175
1200---------1150
1000---------1075
800-------------950
500-------------875
200-------------850
I use this all the time on TW, NX, LoKi kernel and no instability.
Will try your kernel later when I get to charge it a little bit more.
Lets see how those undervolts go :thumbup:

Ok, 20h+ uptime without any glitches. I will now compile the GPU undervolting test build. Feedback welcome!
EDIT: cm10.2 kernel will also follow
GPU undervolting test build #2
Slightly increased lowest GPU step from 133 to 134MHz as Tegrak was reporting an actual frequency of 115MHz. It should be even smoother now.
CPU voltage is stock, while the GPU voltage table is set as follow :
Code:
mHz mV crash nominal delta
267 900 800 1100 200
200 850 750 1100 250
134 800 <750 1000 200
Download the build here : raw_kernel_r1_gpu.zip
Same advice applies. This is a TEST BUILD. Please report back !
EDIT: I spotted a mistake in mali_platform_dvfs.c which was setting a higher voltage than needed when ASV_LEVEL was set to 0, so I set it to 1 (fix included in this build). Default voltages are 1100 and 1000mV in CM10.1 while it should be 1000mV and 950mV

Hi! Just to clarify. Does this new build raw_kernel_r1_gpu have stock CPU mV like in OP or is this packed with the test build raw_kernel_r1_cpu from above?
Thanks!

This build indeed has stock CPU voltage table as said in the previous post. Thus if anyone has a problem, it will help me to fix the right voltage table (cpu or gpu).
However, the next r2 build will have both included. Also, you must know that the modifications only affect group B as I can't test for group A or C, and group B represents 90% of the Notes out there.
Hello! This is my first kernel, The UnleaZhed XTZ Kernel. I'm a noob in developing a kernel, so some bugs may be found in this kernel and I may not be able to fix them!

Will do but it may be done in the next month, Thanks for your suggestion.
First of all THANK YOU for spending your time on this and sharing your result with us!
Just flashed the kernel! Good news...nothing is bricked
CPU Spy Plus indeed shows 1836 Mhz used! I did´t do anything for that.
You might re-think this. Using 1512Mhz instead by default and let the users choose that high speed CPU mode themselves as it may not be stable on all devices.
That 324Mhz added is a huge step...there is no step in between possible?
What about voltages. Did you modify anything? Is the voltage raised to achieve the high cpu frequency? Please post some more information about what happens here...
In fact I´m just running Antutu to see general stability on my device.
VERY BAD score. Before your kenel there were 20300 points. Now with OC only 19746.
=====================================================================
EDIT: Just recognized.... several questions are being answered by Antutu CPU Master.
1512 IS USED by default!
1620Mhz and 1728 Mhz are there to choose and of course finally the 1836Mhz.
Scaling is interactive by default (changed to my fav ondemand)
I/O Scheduler is cfq by default (changed to my fav noop)
Antutu Score @ 1836Mhz: 16077Mhz ???
Lower than without OC? Needs retesting (14230 point when setting max to 1836Mhz and Min to 1512Mhz(!!!???)...maybe the benchmark is wrong...Will give it some time to see if I myself feel a speedup.
After Restart Antutu Score ends up @ 19761 points...not bad. but clearyl not enough looking at the massice OC done. REBOOT! Tab just rebooted! So 1836Mhz is not stable at mine! Trying 1728Mhz now instead.
18139 points....this kernel lacks some serious power if we can believe the scores of antutu. This is a V0.1 so nothing to worry too soon. You´ll make it find it´s power
Switched back to kernel from pulser_g2 (http://forum.xda-developers.com/showthread.php?t=2444452) and 19908 points without any OC! You may look into it.
But please answer the other questiones I wasn´t able to clear myself.

Sorry for my late,
I've tested Antutu with 1512MHz and 1836MHz. For my Tablet Z, I got ~20000 (1512MHz) and ~23000 (1836MHz).
My Tablet Z has fast binning CPU. Can you please tell me which binning your CPU is? Thank you!
hard to tell...did taht thing in Terminal emulator....it tells me "1".
Not fast or slow or anything...

Don´t know....after the disastrous performance of the first release I of course switched back to stock.
Now there is the new version which does not cut performance in stock mode.
I´ll OC now to 1728 Mhz and see how it performs with that....battery life is not really good with stock so if you are already asking...FORGET ABOUT alternative kernels not optimized for battery.
That is why I don´t use CM oder AOKP on my Note1. I just eats the battery for breakfast....
OK OC just seemed to scale...20300 points (ca. 19300 at stock speed)...trying 1836 Mhz now.
17389 points....clear drawback....possibly because my device seems to have a bad CPU from what I´ve learned....wanted to use the 17xx Mhz anyway....oops....device just rebooted....my device just isn´t capable of the max cpu setting. :crying:
Anyway the working 1728 Mhz working is great news!
Will give it further testing...
I have two APQ8064 devices, Nexus 4 and Tablet Z. Nexus 4 is 0 (slow), it will reboot sometimes even on [email protected], the Antutu would force close and red light of death would happen if you ignore it and attempt to run again. While my Tablet Z is 2 (fast), this can run at [email protected] and got 23XXX in Antutu.
I don't have an idea which frequency can the 1 (nominal) APQ8064 clock at, but I think [email protected] will be OK. Also, keep eyes on the CPU float-point section in Antutu. At 1512Mhz, it is around 2000. At 1836MHz, it is around 2200. If this drop lower, just pull up the voltage BUT NOT TOO MUCH!!!

Raising voltage is not an option to me. But anyway...which app do you use for that on tablet Z?
What App do you use for cou control?
I use No-frills. Do you change "interactive" and or "cfq"?

What is the terminal command to find out? I also considered custom retelling to add some processing oomph. On a per app basis, but reading this... Stock SGP311 on 4.2.2 is chugging fine just north of 20000 points on Antutu. Can we compare Versions? Mine is 3.3.1. I faintly recall reading they mixed up some benchmarking internals because some corporations found loopholes to cheat / inflate scores on new to market devices, maybe that's the discrepancy there?
Another wild thought, could there maybe be, aside from different CPU Models, different kinds of cache / memory scattered through the devices? Would not be the first time a sub par. Cache/Memory bottleneck severely strangled a nominally and factually quicker CPU into much lower overall results. Much depends on weighting within Antutu
Man, what happened with your kernel? We need some stock kernels for 4.3

When I start my day with my phone my ultimate goal is to get the most out of my battery. I have a Nexus 5 which is great phone but one downside is that the battery which is 2300mah can barely get you through the day. One way to help this issue is to under volt your CPU, the nexus 5 has a snapdragon 800 CPU clocked at 2.26GHz which is power CPU but at times it can run a bit hot and use more juice than it needs. By Under Volting your CPU your device will run much cooler without losing performance. (Warning if you go too low with the voltages your device will freeze and randomly reboot. ). The voltages than the nexus 5 ships with are a bit high I've been able to under volt up to -75mah without losing any performance however your experience may be different. To under-volt your device you need to have a rooted phone with a custom kernel installed. Franco, ElementalX, and Codeblue are few a few of the many kernels you can use with the nexus 5. I've been using ElementalX as my kernel for a while now, although Franco is also a good one. I use the ElementalX kernel app to manage my voltages, its a paid app but its definitely worth it. you could also use the Kernel tweaker app to manager voltages as well. I've set the governer to elementalx and i set the max cpu freq to 1574MHz, and the max screen off frequency is set to 729MHz. Don't go to extremes take small steps. Please let us know your results here.
This is what i have so far.
300MHz = 650mV
422MHz = 650mV
652MHz = 700mV
729MHz = 720mV
883MHz = 740mV
960MHz = 750mV
1036MHz = 760mV
1190MHz = 780mV
1267MHz = 790mV
1497MHz = 830mV
1574MHz = 845mV
1728MHz = 875mV
1958MHz = 945mV
2265MHz = 1000mV
Edit:
my pvs is 2
300MHz = 650mV
422MHz = 650mV
652MHz = 700mV
729MHz = 710mV
883MHz = 730mV
960MHz = 740mV
1036MHz = 750mV
1190MHz = 770mV
1267MHz = 780mV
1497MHz = 835mV
1574MHz = 840mV

You should be able to go as low as 650mV for both 300MHz and 422MHz., without experience unstable behavior.

Just remember in a couple weeks if you notice stability issues or your phone rebooting, it's probably because of these changes.
Personally I value 100% stability, and I'm already able to achieve the same battery lifeout of default clocks and voltages as well as stock ROM and kernel. Such as these 5-6 hour SoT examples using 40% Adaptive Brightness.

Also I think you'll find lowering the voltages by 5-10% doesn't make a noticeable difference in battery usage, thought it should run cooler and throttle less.

Going to give this a try. I've had good success undervolting other handsets.
With latest code blue and adiutor app cannot set 650mv for 300mhz and 422mhz, lowest i can go is 700mhz not sure why though. Thank you anyway, I'm trying this out.

It's the kernel the lowest you can go with code blue is 700
So, I went on a "boredom rampage" and I've read an article about a guy overclocking his 865 GPU to 865 MHz and reaching Adreno 660-levels of performance and I decided to give it a try and it was awesome.
Problem is, I'm too much of a thinkerer and I pushed the GPU as much as I could. I ended up on 2000 MHz with "TURBO" voltage profile and it's rock solid even on 2100 MHz with the same profile but KonaBess gives me an error if I try to edit the GPU tables after I booted at 2100 MHz.
I even edited the clock profiles to make it smoother, starting from 305 MHz to 600, 800, 1000, 1200, 1400, 1600, 1800 and 2000 with the right voltages.
Now, the battery and SoC temperatures are the same, the battery drain is basically the same, some other fellow modders with the same device (Mi 10T Pro 5G 8/256 with Pixel Experience Plus ROM) didn't manage to hit the same clocks, crashing even with 1000 or 1200 MHz, with my file from the KonaBess app.
So, have I been extremely lucky with the silicon lottery or it's just an illusion?
Please ask if you need ANY benchmark or proof. I've been monitoring the GPU clock with Franco Kernel Manager Live Monitoring and the clock is solid at 2000 MHz and the 3D performance has at first jumped and then slowly climbed, especially on 3DMark Wild Life Extreme. Wild Life Extreme Stress Test is stable the temperatures are fine.
Do you guys have any questions/suggestions/requests?
Edit: Here are some 3DMark runs, both Wild Life and Wild Life Extreme at stock and 2 GHz. I use Greenify, my storage is 94% full and all my processes in the background take up 4 GB of RAM and I didn't touch the bus for the various steppings for the clocks, so I believe that if heavily tuned, this could make a difference.

I have the history of all the bench on 3DMark, because I downloaded it just for this. Would that be ok?
it seems fishy, a 1ghz+ oc would increase your fps by more than that.

It doesn't have the biggest of bumps from 900 MHz to 1 GHz or 2 GHz, but still, is capable of doing it and rock solid too.

i don't think your gpu is actually running at 2ghz while you are running a benchmark. going from stock to 2ghz would at least have to give you an extra 20-30 fps in Wild Life.

Not necessarily. The GPU IS running at 2 GHz but I think that the problem might be some diminishing returns where the clock doesn't mean anything after a certain point.
Are you try locking the freq on 2ghz in Kernel maneger ? Set min and max to 2gzhz with performance governor .

I've made various frequency steps. 400, 600, 800, 1000, 1200, 1400, 1600, 1800 and 2000 MHz. But if I change the governor, after I reboot, it will be msm-adreno-tz again. Max frequency is still 2000 MHz and minimum 400 MHz.
Yes after reboot is resets like on every phone you have to check apply on boot and select min 2000GHZ and max 2000ghz GPu freq in tap in FKM and set gov to performance and do benchmark like 3dmark wild life . Like that. And in Smart pack Kernel manager free app is GPU throttle turn that off.
Check box apply on boot and after boot will be apply.
And that you can show improvements of OC

Can you share your Konabess txt file to import. I"m buying it I and want overclock.

Thanks What is temperature ? Do you game with that or this just experiment ?
Temperatures are roughly the same. I do game with that. On normal games, frequency stays at 400 MHz, but on really heavy games like Genshin Impact, completely maxed out, depending on the scene, the GPU goes to 1.6 or 1.8 GHz and rarely at 2 GHz during some heavy cutscenes. 3DMark keeps it at 2 GHz all the time.

Hello, excuse my ignorance, but I want to learn what konabess is, it's an app or a magisk module, I also have the xiaomi mi 10t pro with DotOs rum android 11 and then I want to play more fluently, could you help me
konabess app is software you can overclock GPU and undervolt.
You need root and that it.

Here tutorial but it old I need make new one because there isn't good one tutorial about it.
This doesn't make any sense. Why would Qualcomm leave so much on the table ?
