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.

Hi,
I'm running CM 10.1 with Werewolf kernel v007. At 1600 MHz the CPU is stable, but at 1700 MHz, the phone freezes and I need to remove the battery. Any solution to make it stable? I tried to set 1325 mV instead of 1275mV, but the SetCPU crashes.

Try another over-clockable kernel, but i advice u to stay at the 1600 mhz no more.

I wouldnt worry about it, the difference between 1600-1700mhz is tiny and a 100mv voltage jump is a big jump to get 1700 stable. Personally is underclock mine to around 1200-1300

well, in that case you have no choice but to stay at 1.6GHz...
and two more side notes: i'd recommend tricksterMOD for such things like UV/OV, ... (i use it myself as well --> "guaranteed" working )
and the max voltage is capped @ 1300mV. more would be too much (remember, we have mobile device with no cooling, not like a lappy )
I would stay at 1600 MHz. The battery gets hot enough without pushing the phone.
I for my part had it underclocked at 1200 and after Optimux Prime kernel Im using 1500MHZ.

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...

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?

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.
Hi guys !
I've been trying to add overclocking to Android One, I'm able to add another frequency (both Overclock and Underclock) but I'm able to test it, the 1391 MHz was the stablest overclock frequency I could get. Decreasing frequency lower than 590 MHz makes booting slower (I don't know why).
Check the screenshot, I'll report more news once I get things finished.
I have attached the mt_cpufreq.c just in case anyone have a kernel source and want to try the overclock.
EDIT: It seems max frequency can't be changed since it's hardcoded to 1.3 GHz, it keeps jumping to 1.3 GHz when screen is turned off, but the frequency sticks when phone is rebooted, but not on screen off.
Click to expand...
Click to collapse
EDIT2: It seems that mt_ptp also controls DVFS, which is interesting. This means we have to edit two files and disable restoring frequency to its default table.
Click to expand...
Click to collapse
EDIT3: I found this in mt_cpufreq.c :
Code:
static unsigned int g_max_freq_by_ptp = DVFS_F0;
Which is defined in the same file, the DVFS_F0 is :
Code:
#define DVFS_F0 (1300000) // KHz
The DVFS_F0 is 1.3 GHz, this might explain why the max frequency keeps jumping to 1.3 GHz when screen off. But this is just an assumption.
I've added mt_ptp.c just in case anyone want to checkout and help the development.
Click to expand...
Click to collapse
Interesting
I had given up all hopes of low level modifications such as over clocking /underclocking/under volting and kernel level wake gestures like double tap to wake etc... This gives me something to look at. Thank you
It seems that max freq can't be set to other than 1300 MHz / 1.3 GHz.
Can anyone here using CM12.1 confirm this bug ? Since it might be because of the ROM but I'm unsure here, it can be either ROM or my custom built kernel.
BTW, 470 MHz isn't fully implemented, the kernel refuses to use it. It might be because I haven't defined it in the volt switch function.
EDIT: Another possibility, it seems on mt_ptp, the clock are either hardcoded or defined in other file. So I have to say that overclocking might be still far away to be achieved.

Depends, does your phone kernel source exist ? If yes, then you're free to try. If not, then don't.
BTW, please don't think this is just a 'install the .c file and get overclock'. It needs many work, and such, I advise you to have at least some advanced knowledge of Linux Kernel.

So, tell me a safe way in which I can underclock my Sparkle V (Stock 5.1)...
Using trickster mod??
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.

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

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.
