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 guys,
does anyone have a tried and working UV values for best battery life? I don't want any more performance, so I'm not looking for OC, but perhaps any idea what UV stays stable?
Well, it's easy the higher you OC, the more it will drain your battery. As for UV, I can't tell because the voltages are different for every device, Rom and kernel...

Usually undervolting -50mv for each speed will work for most devices, although its not recommended to decrease that much for speeds below 800mhz since it will affect your phone's wake up speed.
And tegra 2 cpu controller only supports minimum of 770mv, going anyway lower than this value will not have any effect.
My advice, try UV -25mv for 500mhz, and the rest above is -50mv. Some o2x can go -100mv, but you need to be lucky to own such device.
Cheers!
Mine is working perfectly on -75.
But when i go to -100, soemtime freezes device, so i use -75 regularly.
trying -50 across the board now, seems to run stable.
brw, how does lower voltage hurt the speed?
I can't really explain clearly since I do not know the technicals, but from what I read in xda, it will affect your speed, meaning 1.2ghz running at undervolted setting will not run the same as at stock voltage. Maybe its an efficiency issue, I do not know.
I thing that i experience, If you undervolt too much the few lowest clock steppings, you sometimes might not able to wake the phone from sleep because there is not enough power to wake it up.
I hope my explanation help you a little, and hopefully someone with more experience can give you a better explanation.
using -25mv ate 1.1ghz and 1ghz, -50mv at 800 Mhz, and -100mhz (750Mhz so its 770mhz because hardware limitations) on all other frequencies!
-50 mv is the limit for the device don't use below -50mv. but it dependes on your device. mine cannot UV it always gives me SOD i think my hardware phone is crap

When did you buy your phone?
I have one of the 10 first phones sold in Sweden and I cannot undervolt mine at all.
Just wondering if there's any correlation between manufacturing time and UVability (yeah I just made that word up).

I run with 1100.. good compromise between speed and battery life i think
Hi guys, some times ago I flashed Semaphore, but it haven't any CPU step higher than 1000 MHz. Can I have more CPU steps,like Devil, in Semaphore? (100-1400 MHz)
(Sorry for my bad english)
Download Semaphore Manager from the market. You can overclock using that app. Mind you, semaphore kernel can get glitchy at ~114% OC and up, so you might want to go with 110 and build gradually until you find a sweet spot...

Yeah, I know that, but with Live oc my limit is... 106 % :crying: I have tried every thing but I don't know why the CPU is so limited...
Heh, mine caps at 108%. It would be nice to "normally" oc to 1200mHz on semaphore. I could get 1296mHz with 108% like on Devil.

the "live oc" has better performance of "simple oc" (at equal overclocking), because "live oc" overclock all frequencies and not only the higher frequency.
But with "live oc" you can raise less the frequencies

The only limit is your device. If your CPU/GPU doesn't like OC - you have to live with it (or buy another I9000 :cyclops: )

Theoretically yes, but if you overclock BUS, your CPU, GPU, and RAM are OC'ed. On stock BUS is clocked at 200mHz. If you use LiveOC 110%, you overclock everything by 10% - GPU goes from 200mHz -> 220mHz, CPU from 1000mHz -> 1100mHz. That's why it's more unstable than normal OC.

You might be able to get a higher stable overclock with voltage increase; available in later versions of semaphore, but that's something you'd need some guidance doing, and of course there are the general risks of that.

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"?
Numbers right after reboot and stopping some unused apps...just stock apps running...
2729 / 930 / 1112 / 1050 / 511 / 927 / 1436 / 5278 / 696 / 600

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

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 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.

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.
