You could set your phone to 25mV and it would still be actually doing 800mV as its capped in the kernel to that.

750mV is actually 800mV as thats the MINIMUM.

Do i need to say this again

800mV is the MINIMUM, if you set it below that its STILL 800mV

​
[Galaxy S II Original Android Development] SimpleNick:
you've said it, i've read it, yet you are missing my question.

my question is, if the cap is there, why would a different of 10mV (working 760mV vs. freezing 750mV) cause a freeze?

it's a technical question, and i'm looking for the rational of how the mechanism work, that causes this behavior.

and expanding from there, what are the caps for other freq steppings, assuming there's one for each of them?
[Galaxy S II Original Android Development] JAG131990:
This kernal is so good and power efficient it even charges the phone itself without an external power source.

Edit: apparently I don't have permission to upload on xda forum using tapatalk and tapatalk self hosted feature clearly offers shocking quality. So disregard this. The screenshot depicts a spike in the battery percentages

Here's something really important - how do you pronounce your username?

Is it:

1. Hay-ker - like Acre, but with an H

2. Hacker - like clacker, but with an H

3. Hack-reh - like the sacre in sacre bleu, but with an H

4. Hacer - like the bad computer manufacturers with an H

5. Throat warbler mangrove - but with an H
[Galaxy S II Original Android Development] kalpik:
Hacre is pronounced as "Ninpo"

The H is silent you see!

Cheers to the devs, as if the phone wasn't fast enough on 1.4, now we've got the "even more fasterer" 2.0 goodness.

Looks like I missed out when I had my Hero, this is comedy gold. Phone enhancements _and_ entertainment? Surely too much to ask!
[Galaxy S II Original Android Development] antiochasylum:
Not that measurebating matters with benchmarks, however nenamark2 I got lower FPS at 1.6 than 1.2. ::shrug::\

edit: is this ro.secure=0?

edit2: yes, just remounted her :P
[Galaxy S II Original Android Development] bluesith:
again , i'm hoping i'm not treading on the dumb question line , but

coming from chainfire kg2 kernel , flash over it and enjoy ?

and,

The version of cwm i have will work just the same ?
[Galaxy S II Original Android Development] antiochasylum:
Yes, yes and yes :)
[Galaxy S II Original Android Development] Hacre:
It is ro.secure=0.

In my many years of overclocking, I can confirm that if an overclock is unstable, but not unstable enough to crash, it can cause apparent performance lags due to repeated cycles/instructions that occur due to error, the errors caused by the overclock. Hope that makes sense, it's late...
[Galaxy S II Original Android Development] antiochasylum:
Perfect sense. Guess I'll just run @ 1.2 :P

Thanks for your work :)
[Galaxy S II Original Android Development] Dancube:
I noticed after flashing this some slight hiccuping/pausing while listening to poweramp with my screen off. Is this likely to do with the kernel?

I came from the stock kernel that comes with Cognition 1.15 (I think this is Ninphetamine 1.4).
[Galaxy S II Original Android Development] Hacre:
Hmmm tested here and it's fine. Are you changing the CPU clock or the voltage?
[Galaxy S II Original Android Development] jonny68:
Cheers for this just flashed it...
[Galaxy S II Original Android Development] tobeman:
used to have a hero - glad I got me a sgs2 - sticking around with Ninpo and his splendid dev-art
[Galaxy S II Original Android Development] Dancube:
The CPU clock, I had a screen off profile set up, I'll try it without that enabled.
[Galaxy S II Original Android Development] Hacre:
Possibly that, what did you set it to for screen off?
[Galaxy S II Original Android Development] sicopat:
Hi and thanks for this kernel :)

What i found :

* CWM 4.0.0.2

* Rooted

What I dont know :

does it allow init.d scripts ?

does it allow custom bootanimations ? edit : NO

Thanks again :D
[Galaxy S II Original Android Development] Major_Sarcasm:
I'll be sending a donation later today. Not for the kernel, just for the first post.

[Galaxy S II Original Android Development] netarchy:
If you're limiting the cpu clock with a screen off profile, that'll easily be a problem trigger on any phone depending on how far you're limiting it.

I despise profiles.

I could read that OP and find the download links actually provide a crippling virus, yet still smile with acute satisfaction. If only the first rule of XDA was you HAD to write like that, what a wonderful community this would be. Will download tomorrow and give the new kernel a thorough test.

Have you tried adjusting the audio buffer in poweramp?
[Galaxy S II Original Android Development] el.motar:
Just a thankyou.

I am on cognition 1.5 was quite happy till I read your first post.

I don't usually give much thought to quadrant scores and the like but that op made me do it honestly.

When i first installed cognition and run quadrant was getting around the 3600 mark, just for fun run it after installing your kernel and could not believe the score. So run the thing a few times and it really does speed things up.

My new alltime best score on SGII on quadrant is over 4500.

Many thanks (not sure wether to thank you for the speed or humor ,so thanking you for bouth).
[Galaxy S II Original Android Development] Hacre:
It should allow custom bootanimations. If /data/local/bootanimation.bin or /data/local/bootanimation.zip or /system/media/bootanimation.zip exist, it'll use one of those accordingly.

Thank you very much and remember, it's a donation, the amount doesn't matter and it is appreciated.

not entirely sure on this one, many have flashed without problem. Can you provide any more details about your phone? The output of adb shell ls -al /lib/modules/ ?

Because you are being stupid and going below the cap, goodness knows, maybe your phone just isnt stable at 800mV. Your question is stupid, maybe you should just uninstall setCPU to save yourself and your poor phone.

The cap is a general cap, the higher the freq, the more power it needs, derp.

Basically your phone is not 100% stable on 200mhz@800mV! Ignore the sub 800 numbers, they dont exist.
[Galaxy S II Original Android Development] pulser_g2:
But... she's not a 1337 h4xx0r...

Mind = blown

:eek:
[Galaxy S II Original Android Development] HellRazorGod:
Yo Homies , I've been having fun lately :D

Does undervolting affect performance or stability of the phone by a significant margin ?

coz I was going undervolt to 755 mV at 200 MHz to see the bottom cap of the phone.

It din hang at all,killer performance but when I rebooted , it said Bad SD card and the ROM stopped detecting my SDcard and Internal SDcard . I reset it back to 850 mV but it din seem to help. Do we see the connection pattern here ?

Also the external sdcard is not accessible in CWM . Is it only compatible for CF or you're too bored ? :P

Houston we have a problem , Ninpooo do you comply ?

Edit : Rebooted after reformatting SD cards and all's fine . 800 Mhz it is.

Your internal sdcard is corrupted...
[Galaxy S II Original Android Development] HellRazorGod:
Ahhh SDcard's all fine , both of them . Checked in CWM recovery and card reader.

Was just finding the lower cap for 200 MHz for my phone since I heard every phone has a different processor capability . And I did .

As I said, you are trying to hard to get in post 5...
[Galaxy S II Original Android Development] Lownita:
Hey

Since KG1 firmware a lot of people including me noticed, that the yellowish tint on the left side of the screen nearly completely disappeared.

I tested out several kernels since then and the only custom kernel I found that kept this awesome change made by Samsung was CF-Root KG1/KG2.

My question is: Would it be possible to allocate this "feature" and build it into a kernel like Ninphetamine?

I took some pictures today to demonstrate what I actually mean:

Ninphetamine 2.0.2

CF-Root KG1:

Both of course have been taken under same circumstances, Rom was LeoMar 2.2.

Greetings
[Galaxy S II Original Android Development] mach0boi:
It will be done when 2.3.4 source code is out. I already told ninpo bout this ;)
[Galaxy S II Original Android Development] SimpleNick:
the 100% stability & software cap are overrated, just like stupidity..
[Galaxy S II Original Android Development] Hacre:
Bet it won't, he's trying too hard.

Yes, we know. If you'd read the thread you'd know we know. Samsung have changed the gamma values on the display and there's no comments at all in the source code for where to begin. I could figure it out, but I'm lazy enough to wait for them to release the source code for the KG1+ kernels.

All they've done is provide a workaround for the poorer displays. I do not get a yellow tint on my SGS2 with my kernel. Others do. The workaround is to saturate more blue into the display, with a cooler colour temp. People who don't have the yellow tint will actually get a poorer display quality out of the "fix". When they release the later source I'll make the change optional so people with the better warmer colours aren't forced to have too much blue and people with the yellow tint can still use the workaround.
[Galaxy S II Original Android Development] CrimsonAxe:
This might sound dumb, I'm using Litening rom 4.1 with Ninphetamine 2.0.2

What app should i use to underclock my voltage? i tried Voltage Control and after i've got my settings done, i try to check the current battery voltage it's still at 4004mV? Does that mean the application is not working?

[Galaxy S II Original Android Development] Hacre:
Over here, where it needs to be earned.

Over 600 posts in this thread, only 10 entries on post 5. I'd say respect is being distributed quite fairly. Unless you think there's something about posting on the internet that means no matter how ****ing moronic your post, you should get sunshine and daisies in return? Not in here matey boy.

Besides, you've got more important things to worry about than my treatment of people who say stupid things in my thread, such as the ability to spell "twiter" properly.
[Galaxy S II Original Android Development] HellRazorGod:
Lol Ninpo d(-_-)b

On a more serious note , I really can't access external sd in recovery .

Full CWM compatibility stands only for CF's kernel ? You know its a piece of cake for you. Eat it already,will you ?

To the best kernel maker in the business . Bow in the presence of greatness :)
[Galaxy S II Original Android Development] Hacre:
Already mentioned in the thread that when I get around to sorting out my initramfs external_sd will be sorted as well.

Dear Hacre i just wanted to let you know that i'm going to try your kernel with latest VillainROM (2.3) just because you're the best dork (in a friendly way) on xda.

I can't help but laugh while reading your first post.
[Galaxy S II Original Android Development] EarlZ:
I disagree on this, my whites are still very white w/o any slight blue-ish tint, Im actually very curious on what sammy changed since the color levels are exactly the same, at least on my phone. We just have to wait for the sources to be out so we can really say whats going on.
[Galaxy S II Original Android Development] Hacre:
The colour levels aren't exactly the same at all, I've seen side by side comparison photos showing the issue.
[Galaxy S II Original Android Development] 2khong2:
I have to reply to this...

U must be dying for post 5..
[Galaxy S II Original Android Development] EarlZ:
Side by side comparison on the very same phone with controlled light? I guess my screen is better then to keep the same level of whites, natural whites!

Because if its from 2 different phones then its an invalid comparison. I've also taken shots on my phone. I dont see any difference or a shift in blue color, the only thing missing is to make both sides equally bright OR dim.
[Galaxy S II Original Android Development] Hacre:
Screenshots?
[Galaxy S II Original Android Development] adz63:
thanks for your kernal work . its awesome

thanks button clicke d:)
[Galaxy S II Original Android Development] Hannibal226:
Hi,

just looked a bit around for nice OC/UV -settings...

I ask especially devs (sure all replies are welcome), if this settings are good, ok or more bad (prozessor, performance or battery life)?

Would be nice if u can comment on it, so that i can be sure what I can set my voltage.

Thx in advanced...

PS: Gr8 Kernel at all!
[Galaxy S II Original Android Development] willverduzco:

[Galaxy S II Original Android Development] xenastro:
Hello,

First I would like to thank you for this kernal, I am using it with VillainROM 2.1 and it is working flawlessly, snappy performance and amazing battery life without any fiddling with voltages or clock speeds.

You mentioned earlier that this kernal provides a boost to recharge, how did you achieve that if I may ask?

I noticed high mA values while charging, over 900 mA sometimes (using wall charger), which is amazing!

A question springs to mind, is it still faster to charge while the phone is turned off vs charging with the phone turned on and idle.

I have always thought that the next break through in battery technology would not be a long lasting battery but instead something that you can charge in very short time, imagine charging your SGS2 up full in 5 min, you wouldn't worry much about battery consumption then would you!
[Galaxy S II Original Android Development] Hacre:
Hello.

Yes yes you're welcome. You may worship us now.

It's a configuration change in the kernel.

A wall charger should always show higher current, as it's a wall charger.

Yes of course, as the phone isn't consuming any battery power while switched off. You also cannot get a 100% charge with the phone powered on.

Yes faster charging would be a good thing.
[Galaxy S II Original Android Development] buxz777:
His undervolts are quite low and every device is different so may not work on yours my phone would seem stable at that for a while then reboots when playing flash video or gaming

mine have been asjusted a bit i used to run at about 100mv-125mv under each stock setting but it prooved unstable over a few days and have now adjusted it too

1400mhz at 1275mv

1200mhz at 1225mv

1000mhz at 1100mv

800mhz at 1000mv

500mhz at 875mv

200mhz at 850mv

this has prooved to be quite stable for my device like i say no reboots yet in about 2 days of heavy useage and it is very fast in performing tasks etc

every device is different so yours may not work at these settings or it may go lower .
[Galaxy S II Original Android Development] EarlZ:
Yes screenshots, if its a change in color temperature (SW level) screenshots should show it. I've also taken actual photos but it needs a more controlled environment and a better camera.
[Galaxy S II Original Android Development] Pacifiste95:
Hi

what is "JHash updated to version 3."?

Thanks
[Galaxy S II Original Android Development] Hacre:
...

Pray tell how a screenshot is going to show changes in drivers that tell the screen hardware how to display a picture and at what intensity each individual pixel is supposed to shine?

To give you a clue here, what you're doing is like me taking screenshots to show Samsung that I have a dead pixel on my monitor. In short, it ain't gonna.

Now, please drop this and trust me that it's a change in colour temperature/gamma, as that's exactly how they remedied the issue with the Nexus S. Post 5 is starting to become unwieldy.

This is to indicate that I have updated JHash to version 3.
[Galaxy S II Original Android Development] xenastro:
I meant, your configuration change that makes the phone charge faster, it is a software change, hence, one would assume would only work if the phone is turned on. and that is why I asked if it would charge faster while turned on and idle (exploiting the configuration change).

I am aware that there is some software running while the phone is turned off, example would be Chainfire's application that shows charging options when the phone is turned off, don't know what that piece of software that is running while the phone is turned off is called though!

Note: I am not savvy in how Android or Linux works, but learning from you guys :)
[Galaxy S II Original Android Development] EarlZ:
I was actually checking if they did some software level changes on the screen that would be visible be screen shots, with the yellow tint issue of course I've been using actual photos. I've compared a 2.3.3 and a 2.3.4 kernel, so far the photos (and in real life) dont show any change in color temperature, But anyway thanks for the input, just gonna wait for the 2.3.4 sources and for the other devs to see whats changed.
[Galaxy S II Original Android Development] willverduzco:
Low level (driver/kernel) changes to color temp will not show up in screenies. SurfaceFlinger hacks do show up. However, this does not apply here.

[Galaxy S II Original Android Development] eiraku:
IINM, the kernel actually loads to show you that "turned off charging battery" animation, so yeah any changes Ninpo makes will be there too.

I could be an idiot and be wrong tho.
[Galaxy S II Original Android Development] Hacre:
It's not the kernel running that does that.

The changes to USB charging will only show when the phone is booted. You'll still get full power via an AC adaptor however. Whether the firmware in the phone will pull all that it can from a USB host, I have no idea, although one would assume that it should as I doubt that the firmware is smart enough to know the difference between USB or AC.

I can guarantee it's a change in gamma/colour temperature, search Google for Samsung gamma yellowish github to find where people have flipped back and forth on the same issue on other Samsung devices. Whether you see it or not with your photos is neither here nor there.

I'm happy to leave this "debate" here however until we get updated KG* sources from Samsung.

[Galaxy S II Original Android Development] Nathalex27:
I've tested these settings on my phone only. Stressed 200 to 1600 individualy for 30 min. I experience no problems. But like pc cpu's every phone is different and you should test what settings work best

On your phone. Try these and if unstable find the unstable setting and raise voltage until stable.

Good luck.

(Stressed with setcpu stress test found under info.)
[Galaxy S II Original Android Development] xenastro:
Use the same, amazing app.
[Galaxy S II Original Android Development] Hacre:
Yes, exactly what this guy says. It'd be great if we could stop asking for UV/OC settings or posting endless lists of what people have set as it's a waste of forum space and is helpful to no-one. People comfortable with changing these settings know how to do so already and people who don't can find better information on UV/OC on the internet. Posting "settings that work" in here will only serve to encourage idiots to fry their phones.
[Galaxy S II Original Android Development] Hannibal226:
------------

Thx both for answering!

But the big question for me also is, if I can damage my prozessor (CPU), even if it's running fine or just when I see it's usntable and use this settings further (what surely would be stupid :D)?
[Galaxy S II Original Android Development] Ghazkul:
If we use battery monitor widget, is there a way to know at what mV is getting close to dangerous for the battery ?

Reason I am asking is I just now had my battery at 1% (using 2.0.1) for about 15 minutes and with screen on and I got a bit worried that the phone wouldnt close down before reaching the danger level.
[Galaxy S II Original Android Development] Hacre:
There is always a risk of damaging the CPU when running it outside the recommended specification. Undervolting is usually safe, however.

Danger level? It's solid state storage with a journalled file system, what danger are you referring to?
