[Galaxy S II Original Android Development] BlueScreenJunky:
How do you "undervolt" the screen ? It seems to me that if there's less power going through the leds it will just be dimmer, so that would have the same effect as using a lower brightness...

But if it can indeed lower the screen consumption without altering the brightness this is great news !

looked on quadrant information and after seeing peoples screnshots in says cores=2 mine and my wifes phone says core=1 is there someting i am missing in setttings to enable 2 thx

[Galaxy S II Original Android Development] stesteste:
got the answer from other member

Try to launch system information as fast as you can. This will activate the second core.
[Galaxy S II Original Android Development] BoneMo:
working :)
[Galaxy S II Original Android Development] sorrowuk:
See when you overclock and increase the cpu frequency. Does this overclock the gpu too or just the cpu ?
[Galaxy S II Original Android Development] kzakaria:
Open quadrant and immediately open system info (you have to close quadrant if you miss and start all over) you will have two cores!!!"
[Galaxy S II Original Android Development] aussiebum:
I believe any undervolting of the screen relates to the capacitive layer that enables it to respond to finger touches (ie. what turns a normal LCD into a touchsceen).

its not that surprising that the galaxy s 2 screen can be undervolted; my galaxy tab uses overcome's kernel that also undervolts the screen.

feedback on battery life with chaimd's kernel - I only lost 4% over 10 hours on standby last night (3g data on, auto sync off for everything), so that's pretty good :)
[Galaxy S II Original Android Development] chaimd:
Yep, you are right. ARM core undervolted is not enough;)

I released new kernel. I undervolted not only ARM core and TouchPanel, but also LED, GPU, bus, framebuffer, etc....

Thank you, and any chance we can get you to create your own thread to publish these updates? They work awesome but being able to follow step by step would make things a little easier and known to more people. Also what kind of UV are we seeing in these areas?

[Galaxy S II Original Android Development] nightranger73:
And maybe a battery recalibration could help
[Galaxy S II Original Android Development] aussiebum:
woohoo - it's flashing time! :p
[Galaxy S II Original Android Development] crypticc:
I think interactive prioritises non-background activities, which is great.

What did you modify apart from oc+uv?

does that mean conservative will not use your mods?
[Galaxy S II Original Android Development] crypticc:
two quadrant runs = 2581 @ 1.5Ghz interactive gov. 3.5 is normal for me so even though people frown on quadrant as sole benchmark, I'd say that this is a failure. It' is database writes that is taking too long I think, so maybe one of the nand undervolts is too low...but the problem seems to be related to the governor (see below)

UPDATE: Switching to ondemand governor and quadrant is back to 4k+; mandro shows similar result. Have you tweaked ramp-up threshold maybe?

I can confirm unlocked bootloader and superuseroneclick all works fine, so that's a success for me so

thanks very much

for doing that !

Chaimd, I understand that your kernel is based on the mods made here, but do you think we need a Kernel discussion for yours in another thread? What does OP say?

Update?

Fellas,

Whats the update now on the KE7 OC kernel?

Is it as stable as the original KDD OC kernel?
[Galaxy S II Original Android Development] bclark:
Are you asking about chaimd's from 5/29? I have been running it for 3 days and have had zero issues.
[Galaxy S II Original Android Development] afx69:
Yes I was :)

Thanx for the info bclark.

I've been testing KE7 with Tegra OC; but get reboots. I know I just need to adjust the voltage, but I dont have the knowledge to play around with it.
[Galaxy S II Original Android Development] crypticc:
I think the oc version of this ke7 kernel has some issues.

Would love a one stop shop someday, for rooted plus oc and uv,but for now, I find tegrak applied over stock or chainfire ke7 is best.

Did this a few minutes ago...
[Galaxy S II Original Android Development] Tom-Helge:
Can you tell me what kind of CPU speed and voltages you are using in Tegrak Overclock Ultimate if you are using that to get that score?

And can you tell us what kind of MFLOPS score you get in Linpack?
[Galaxy S II Original Android Development] BoostedSR20:
Using Tegrak Ultimate. The CPU clock was 1.68ghz, and I can't remember the voltages, I was playing with different combos all morning. I should have written them down...

I've also managed to hit 68.6 in linpack @1.740ghz, (I'm still only ranked 185) but I can't get quadrant to run with the clock that high.

Another trick I've been using is to put the phone/battery in front of the AC to get it cold before running, seems to really help stability. Gotta be careful though, I left it there too long and had a decent amount of condensation all over the phone and battery when I came back. :eek:
[Galaxy S II Original Android Development] Tom-Helge:
Ok.

I managed to hit 68.1 MFLOPS with 1.75 GHz though.

But that wasn't stable so that's just to do a benchmark in Linpack to get the most out of the CPU before the phone freezes.

I couldn't get Quadrant to run stable if i took the speed over 1600 MHz.
[Galaxy S II Original Android Development] RandyboY:
How do you even alter the speed? I've installed SetCPU and i cant alter it in an easy way? I'm a noob and need it easy to get it :-)
[Galaxy S II Original Android Development] BoostedSR20:
Go checkout the Tegrak overclock thread.
[Galaxy S II Original Android Development] kickassdave:
I managed to run quadrant several times at 1.7GHz with 1.45v. Not getting the same ridiculously high scores as you guys..
[Galaxy S II Original Android Development] BoostedSR20:
I took a break since trying this morning. But I found the scores didn't go up much past 1.6ghz.
[Galaxy S II Original Android Development] nongrata23:
Man.....

This kernel kick ass!

The most impressive part of it is... when i play games the phone gets hot like 30% of the intensity of previous kernels!!!!!! Also everything runs super slick, very fast movements all over, i am very impressed bout this!

Downside battery drain bit fast but for this quality and speed totally worth`s it...

I hope you can develop more of this and let us know more details about what tweeks u do, maybe open your own post with this kernel... way too cool!!!
[Galaxy S II Original Android Development] afx69:
working together....

Wouldn't it be nice to see chaimd and Chainfire work together on a kernel; chaimd with the amazing OC work; and Chainfire with CWM3.

That's my umtimate kernel :)

Lets dream about that kernel for a while; say some prayers... and maybe???

It you are using quadrant advanced or using chainfire texture memory reductions that's cheating and not a real gain

Quadrant advanced is older than standard and buggy (texture not drawed in planets and quake) and you get same results in quadrant standard using texture reductions

I get spikes of 4400+ on my new device, all stock. Got around 1000 less on my previous SGS2 (got stolen) My SGS1 used to perform better than most peoples SGS and it makes me wonder if one phone can differ from another due to some minor manufacturing differences. My new phone also has no issues with the camera (pink spots) and the previous one did. Apparently the manufacturing process of Samsung is not giving a 100% stable output, but we all know apple has those issues to.

New chaimd kernel ocuv with cwm

Just browsed chaimd's blog and found he's posted up a new version of his OCUV kernel... this time with CWM 4 built in and BFQ I/O scheduler. Guessing this is based on KE7.

http://chai99.wordpress.com/2011/06/14/sgs2-kernel-cwm-xuv-oc/

Changelog for lazy people, copy and pasted from chaimd's blog:

EDIT: If this kernel freezes on the "S" boot logo during boot, go into recovery mode (VolUP+HOME+POWER) -> Advanced -> Wipe Dalvik Cache. Also make sure phone isn't too hot when booting up (let it cool down a bit before starting up with new kernel).

EDIT 2: Download the less undervolted version of the kernel if the 1st one hangs during boot.

and, speaking of tegrak achievements, what about OCing the gpu (400MHz) at top speed while UCing/UVing it (100mhz) at lower level and keeping it stock (267 or 160) at intermediate levels? Or does it work for 3d only? That would be an hell of a governor for interactive

Is there some settings file where we can manually adjust cpu voltages to suit our own phones? I'm sure the settings you use for your kernel work fine on your phone, but maybe not for others, so might be good if we could tweak individually.

nice feedback, do you use profile in setcpu? any detail? please share with us if you don't mind..

[Galaxy S II Original Android Development] aussiebum:
no profile, just Interactive governor and not bothering to overclock to 1.5ghz. I do use Tasker to automatically disable Mobile Data 30 minutes after the screen is off, and to only reenable when phone is unlocked (assuming I'm not on wifi). Saves me loads of power.

EDIT: Tasker profiles to achieve the above attached. One caveat is that only the "Toggle" function for Mobile Data ie. 3g data works flawlessly... the "On" and "Off" method of turning on/off 3g data eventually causes 3g data to fail to reconnect without a reboot. The problem with the Toggle Mobile Data on the other hand is that there is no way (I'm aware of) to check Mobile Data state like with Wifi... so in my profile I fudge a variable to mark when 3g is toggled off/on. Sometimes the variable is updated even though it's not supposed to, leading to a reversal of the profile actions (ie. instead of turning ON 3g when the phone is unlocked, it turns it OFF instead :p), which is easily fixable by going into Android 3G data settings and manually marking "Use Packet Data" (ie. 3g data) on to fix the incorrect state.

I got a little question. I can undervolt everything from 200mhz to 1200mhz, everything is stable.

But as soon as I hit 1400mhz/1600mhz it reboot/crash every time. I didnt touch mV on these frequency and it still crash. So I add 50mV to the base setting, it still crash.

Is there a way to have a stable 1600mhz? I dont care about battery life. I just want it to be stable, I can run some Quadrant if im lucky, otherwise it crash with any app.

Heres my setting running on CM7, I was on revolution before with ninphetamine 2.0.5/2.1.3 and I had the same problem. My CPU doesnt seem to like uv/oc... I cant use the 200mhz-800mV like most of ppl, i need to use 200mhz-850mV

That ( 1.5GHz: 4000+ in Quadrant! ) is a very old post based on old kernel/firmware.

For example stock moded kernel with nothing disabled just few extras thrown in, gets me

But if i use latest speedmod kernel at stock 1.2Ghz gets me over 4000.

However that fast kernel disables some stuff that breaks functionality on some apps. Some of us use those, example "Application Protection" and some kernel revision breaks "Droid Firewall" , now alot of people won't need these apps or even know what they do.

Sadly to this day have not seen a kernel that doesn't break anything and keeps uber speed.
