See where it starts going down in 25mV intervals, do that all the way to the bottom (the app there is Kernel Tuner). The top two frequencies can be dropped by 25, but from there and any lower on the top two and you'll get an undervolt forced reboot. Some of the low end freqs might be able to go a bit lower than what my scale gives, you'll just have to test yourself since every phone is different in the undervolt department. And do not set it to activate on boot until you've pushed your phone a bit and know those voltages work. It is possible to undervolt brick a phone forcing you to do a factory reset to remove the saved undervolt values (or a full rom install if you save bad undervolt settings in an init.d script).

Rom shouldn't be an issue, this a kernel feature to undervolt cpu.

Guessing at the rom....probably PAC 4.4, but like Techno said, that really doesn't matter. And those are lowered.

I've enabled the converse CPU option in the power saver menu and I'd like to know what that does exactly. Does it just lower the CPU's clock speed? What are the best apps to monitor CPU usage?

Lowers your cpu freq tot 1.1ghz, that's all
It lowers your CPU speed to a maximum of 1.1GHz but it does not lower the GPU speeds. For games that aren't that CPU intensive, you can still play totally smooth with Power Saver on

Does anyone know a working CPU frequency set/limit program?
I want to limit the CPU to 600MHz or even 400MHz during driving because I want to use it as a blackbox and record everything. If I can limit the CPU, it won't heat up as bad.
I tried setCPU, antutu cpu master, no-frills cpu control, and everything doesn't seem to stick. I currently have it in energy saving mode, so it's 1100MHz.
The HTC One has an issue with frequencies sticking, it's because of the permlock. You could either flash a custom kernel or you could use setcpu and use the disable permlock feature, which I haven't tested, but it claims to allow frequencies to stick.
You'll need root for all this ofcourse

Hey guys and gals,
I've been searching AHD forums for a while now and I could find zip zero result on custom kernels even though I'm sure that I've read people write about Aaargh kernel before... [his user name's spelling ain't really helping either....]
So here I ask: where can I find it (or other custom kernels?), read what people have to say about it and what results are to be expected?
Lastly, what are you guys settings? I mean what voltages are you guys using? I understand that no phone/cpu reacts the same to undervolting, but I'd like to get an idea on how low I could expect to go...
I'm not really after overclocking as I find my AHD's performances acceptable at stock values; I'm just after better battery performance really.
Thanks in advance for your replies; I will be offline for the next few days, but will sure give thanks hits upon my return.
Cheers

Ok thanks for the link.
I wasn't searching at the right place and on the wrong device forum...
So in an attempt to make this thread useful, I'd ask again: anybody wants to share their experience with that kernel on AHD?
I mean other than getting a phone that can basically now running up to 2GHz and down to 96 MHz, what did you get from it?
- How (and how much) undervolting did you do?;
- Any noticeable and verifiable battery saving doing so?;
- Any before/after benchmark results to share?
- any observations, bugs or just general opinion on the subject?
Personally, I've noticed once or twice that the phone had a hard time waking up when I used 144MHz (forgot the exact value) as min cpu frequency (no undervolting). The screen would not turn on with either volume rocker or power button...it only did after a lot of insisting... And that was just within a couple hours of testing.
I've since reverted to CM11 kernel since I was eager to find out if a semi-dirty (no stock rom reflashing first) nand backup restore would switch the kernel back. And it did, but then I've also re-installed CM11-M8 for other reason/issues... (that too brought back CM kernel - at least that's what the "about phone" is giving).
Anyhow, the debate is open on the usefulness of that custom kernel. If no one dare to pitch in here, I'll just ask a moderator to delete the thread...
But I'm still eager to find out about how to undervolt as I always did on my Defy.
Cheers

I'm also curious about any battery-saving benefits that can be gained with Kernel adjustments; especially when screen is on (since I drive a lot with the screen on all the time). I have no interest in Overclocking, and would rather have the phone last as long as possible and still be useable.
Currently using arrrghhh's kernel (May 23 version) with:
1. Min 384000 (default)
2. Max 1458000
3. Scheduler: deadline
4. Governor: smartassV2
5. App: Trickster MOD
Also, the only way I've been successful in changing anything is by using the Trickster MOD app. Between CarbonROM and the CM11 (epinter) that I'm using now, I've never been able to get the kernel changes to stick. Didn't matter whether I used the default kernel or arrrghhh's, any modifications in my settings always reverted back at some later time.
Trickster MOD uses some workarounds to get it to stay, and I haven't had any issues since.

No. "CLICK TO SHOW CONTENT", then download the latest version (May 23) that doesn't use SaberMod. Only reason I was using that was because arrrghhh mentioned that SaberMod thing was experimental and may have issues. So I just chose the safe option.

Since you're a new xda member, I'll remind you that there is a button specially made to thank people... Look at the bottom left of the post useful to you...
As far as the undervolting goes, I found that the free app called "Trickster Mod" can do voltage changes. So I've done a bit more testing with the May 23rd anykernel and my results weren't that great....
First, I went too aggressively and try to lower the voltage by 150mV for every cpu frequency and that made the phone reboot as soon I applied it. I mention this because the lesson here is to
*** NEVER SET THE "apply settings on boot" OPTION UNTIL YOU ARE ABSOLUTELY SURE THAT YOUR NUMBERS WORK FINE. ***
Not doing so might make your phone unbootable and you might not even be able to boot to recovery/bootloader mode to revert kernel/settings....
Ok, that being said and since I'm after battery saving while the phone is in use*, I then went ahead and lowered by a more reasonable 50mV for each frequency (the app let's us move by 25mV steps). That 'worked' fine and I've experienced no sudden reboot. BUT, after some time (30 minutes), I've noticed some slowdowns and I've also had issues with an app that stopped creating video thumbnails. So all in all, that called for the end of my testing and I restore my CM11-M8 nandroid as I'm not going to live with such drawbacks for some slight (still yet to be proven) battery improvements.
So no custom kernel for me afterall.
.... Should this thread be deleted???
You guys tell me.
Cheers

*: hence I see no point of lowering the minimum cpu frequency: my phone does not take excessive power when on iddle, it deepsleeps fine and I use airplane mode at night..
*': some have argued that increasing the max cpu frequency allows the phone to complete tasks faster and return to a low power state sooner resulting in a lower overall battery use. I have my doubts on this and I'm pretty sure that it depends on what kind of task the phone is mainly doing. Anyhow, this is not something worth testing at this time... My AHD does its job just fine at the stock max cpu f.

I am NOT responsible for anything that happens to you, your phone, or anything as a result of flashing this kernel. It is of your choice to flash said kernel and or proceed to root your phone. So dont blame me if your phone is dead, it is YOUR fault.
Features:
Code:
F2FS Filesystem support
Write Protect Removed
Less aggressive interactive gov
Overclocked Ram to 566MHz
Overclocked Gpu to 477Mhz (will not be visible) test this and tell me if you get any performance jumps in gpu intensive games.
To do:
Add better touch drivers (maybe)
Add ram space and trim already used ram.
Add any optimizations possible.
FYI's
Code:
Requests,
You guys should request any feature you want added! :D I'll get around to
trying to add all of it!
Give me time.
I am a very busy person, I have school and a almost full time job. I'll work as
hard as I possibly can on all of this but you have to be patient.
I am sorry if I say something will be uploaded and its not. I don't have a way
to do builds and its hard to work on ROM's without constant access to a pc.
I will try to update the OP if plans change.
Fixed (Cameras, WiFi, any lags or old bugs)

Look at the tags. Im working on adding dt2w and the smartass gov. cpuboost (better power to performance managment) wheatly and intelleactive are already working. me and rbheromax are trying to get this all sorted out. His current builds have broken wifi. Mine had wifi at first and i didnt modify any wifi drivers so it SHOULD in theory work.
All in all at the end of the day (not today) the kernel will end up featuring dt2w, 3 new govs, overclock, maybe voltage control, and support lots and lots of file systems. Oh cant forget write protect is removed lol.

Faux sound support?
Hmmm feature request...well fauxsound, row scheduler(others), I think this kernel can be throttled up to 1.5 or 1.8 ghz per core, but for battery saving, 1.5, maybe seeing if you can update some of the drivers(personally when I hit them c++ books(c) I would modify), screen configurations if possible like faux, but I do not think HTC allows developers to mess with the display driver, and possibly extfat4 partitioning.

As for the kernel level cpu oc at the moment its not possible. Every attempt has resulted in a non booting kernel. For now my development will be slow until i can get my hands on a laptop. Sorry guys. Ill update my kernel and rom in unison from here on out (usually) but its gonna be a while. Sorry again everyone. Thanks for the suggestions though I will get to do some tinkering this saturday and next saturday. Ill report back then.
New image uploaded!!! (It is in the downloads section) If you cant download it heres another link:
http://www.mediafire.com/download/5d1iwc4brvey8z0/boot100.img
@ anyone running this please post me the output of /sys/kernel/debug/msm_cpufreq
Where's the download link
Will this work for Boost Mobile?
Flashing this kernel gets rid of all Roaming related options from the phone, before I used to see the option to enable roaming, plus enable/disable roaming guards and enable roaming for domestic and internationally, all that is gone after flashing this kernel. Since I have a roaming agreement with Sprint and I travel alot, I can't do without the ability to roam, therefore I restored my /boot nandroid backup and that brought back all roaming related options.
Question: Why did the OP remove roaming from this kernel? Many people NEED this, Or is there something that I was supposed to do in order to bring it back?
Hi,
does anyone tried to optimize the gpu of the SD888 Soc via KonaBess?
i found a post with a list of changes a user made. https://forum.xda-developers.com/t/...-root-and-konabess-app.4275089/#post-85555809
So i used the same settings to maybe save some battery.
I'm not a phone-gamer at all, but i tried to OC the gpu a bit. Not because i need it, but i wanted to see what's possible.
850mhz is working fine. If I set 860mhz even with higher voltage level (LEVEL_TURBO_L2) the phone won't boot. So i stay with 850mhz.

If youre interested, i exported my settings (150mhz added, UV, OC to 850mhz), which can imported in the konabess app.
Via app you can import/export settings and save your vendor.img. If the boot fails, flash your backuped vendor.img via twrp and the phone will boot again.
Maybe we can gain some more perfomance or better batterylife via undervolting.

I have lowered the voltage on my 11T Pro using KonaBess.
If the voltage on the high frequency side was reduced too much, the drawing of the 3D bench collapsed or could not be started.
Also, if I reduced the voltage too much on the low frequency side
The home screen would freeze or collapse after startup.
Therefore, it seems that the GPU voltage is actually being changed.
In the default state and after lowering the voltage
Wild Life Extreme Stress Test, respectively.
the score for the lower voltage was
all exceeded the default score, suggesting that the lower voltage
throttling is suppressed.
We have been using the system for several weeks in the low voltage state.
The operation is extremely stable.
Of course, there are individual differences in margins, whether for OC or lower voltages.
@cyphone
Sounds great. Nice that you tested more then me. Did you noticed some improvement in batterylife or does the phone feels cooler?
Why did you used the app at all? Just out of interest or did you aimed for something special?
Can you share your stable settings and/or list your changes, to let me and others try the same settings?
EDIT: Okay, seems like he won't respond. Sad.
On the stock Chinese ROM, I noticed that the GPU is locked to 305 MHz. Can we change some settings to increase this? For reference, the GPU's max speed is 650 MHz.
I'm 90% sure this works. Search for "manage my games" in the settings, and check your games. That will boost the GPU clock speed. With the stock rom you can use the time widget with cpu/cpu clock speeds, and if you open a game and then go back to the home screen you'll see the gpu/cpu at a higher clock speed.
Oh, there's also a bar at the top when you're playing a game and it shows cpu/gpu clock speeds, temp and fps. Even at the stock clock speeds I have great game performance.

I already use Legion Assistant but did not see the GPU increase its speed. I guess the game isn't supported, or the increase in GPU speed won't help (the game relies on CPU power more than GPU)

the cpu and gpu increase in speed. Even if you choose beast mode you don't see a cpu increase?
The CPU changes its speed but the GPU is constant at 305MHz, even in beast mode. I guess the game doesn't need it. I haven't tried other games sine I only play one android game right now, and the tablet's other uses are for videos and manga reading.

Didn't work. Anyway I've tried another game and the GPU Mhz increased.. So the game (Ragnarok Origin) really doesn't need the extra GPU power.
It goes up to 670 Mhz in CODM if I set it to beast mode...
