[Q] OC problem

i've heard some people can OC their GIO to 921MHz stable, but on my gio it can't even get stable on 883Mhz. on 864MHz is somewhat stable but i still get hung or FC randomly, im super stable at 844MHz.
Why does my phone can't be OC like them other guys?

Not all devices are made exactly the same. Processors can behave differently as do the batteries and other hardware.

is there nothing i can do? i've tried many ROMS, on some i can get to 921 for a few seconds, but still the same. will changing kernel help?

Why not stop overclocking ? Just find a very fast rom and then you can save the overclocking , hence the instability and hotness and draining battery. That way you will have longer life on your Gio.
L.E. : just change the minimum frequency to 245 and refrain from using roms that are heavy right now , like CM 10.1 , try anything based on gingerbread like Adrenaline or Enhanced 2.3.6 or DebianDroid for example , or AOSP ICS wich i find very fast.

well currently im using AOKP milestone 6 CM9 based, i use conservative governor 245-844MHz, installed adrenaline engine 4.4, and pim my rom and set my OOM and LMK to medium settings. battery is drained only when im using data or playing games obviously. actually this ROM is superb for me performance wise, its just, i feel like i can squeeze a bit more of it for playing games you know. its like i see this slight lagging and i thought if only i could use a little more CPU power, the lag will be gone

Even you can overclock a 1st gen AMD Duron to 2Ghz with liquid nitrogen, it just doesn't make sense doing it

AW: [Q] OC problem
i can oc my cpu to 960mhz but i think it makes no sense... you don't feel the extra speed in normal use only in benchmarks... my cpu is set to 480mhz because it's enough for every app i am using (facebook, whatsapp, xda, browser and so on).

[Q] SE Xperia Play & CyanogenMOD 10

Hello guys and girls, i just installed the Cyanogen MOD 10 by FXP Team and i was wondering what settings i should use in the "Performance" tab, for Min CPU, MAX CPU, RAM and I/O Scheduler. I just wanna use my phone for daily use and also games from time to time. Any other tweaks or ideeas ?
Thanks!

For daily use I recommended same settings like masteril said. For gaming use 1600 Mhz/249 Mhz, performance, deadline.

for daily use, if your using turbo kernel, i'd say for the governor = intellidemand and for the I/O = sio; max clock 1.018 GHz and min clock 184 MHz. I got amazing battery time with those settings just listening to music and playing online casual games and emulators, but sadly Jelly Bean and emulators don't get along very well because most of the "oid" emulators don't work properly on Jelly Bean (not just CM10, PACMAN and Paranoid also) and when ever I touched the touchpads the games stared to lag. So I went back to Gingerbread for gaming, best battery and smoothness

[Kernel] [CM9 - RC2 & RC3] honeyx 7up 2.6.35 kernel [for better battery life]

Due to some requests via PM´s I decided to make my kernel finally public, but remember:
This kernel is a personal kernel for my private use, so it´s only containing the tweaks I´m also really using
It´s the older 2.6.35 kernel basing on latest 2.6.35 sources from Arco, so only use it with Arcos CM9 RC2 or RC3 or a custom ROM with 2.6.35 kernel
This kernel is not filled with a lot of governors and schedulers, but only the ones I´m also personally using.
I have made this kernel because non of the custom kernels worked stable for me in the past, even at stock voltages. With this kernel I´m able to run at extreme Undervolting rock solid.
So this kernel was created with stability and battery life in mind. Each modification was tested separately, so everytime I added a tweak or a new feature, I tested the new kernel for a couple of days before adding the next one.
So why I decided to tweak this older kernel rather than going with 3.x kernel?
- Because this kernel is giving me a much better battery life than the 3.x kernel, is running rock solid and also because I don´t really need the new features added into 3.x kernel.
So what it has included:
- UV and OC options
- lowered WiFi voltage
- lowered lcd voltage
- slightly lowered standby / deepsleep voltage
- Battery life extender
- Fixed 100% battery notification after charger unplug
- 377MB RAM
- NO-OP scheduler as default scheduler
- Lulzactive governor as default governor
- tweaked Lulzactive for battery life and smoothness
- added 518, 633 and 902 MHz (new)
- screen off frequency set to 518 MHz max.(new)
- some more voltage tweaks
- no other compilation tweaks just to make the list longer
With this kernel and a new battery my SGW can last up to 7 days in standby. This is without WiFi and Mobile Data. With the stock kernel I got 3-5 days. It´s also working absolutely stable and smooth for me without any issues.
So if you run into some issues that are/were also discussed i the CM9 Bug report thread, don´t blame me for them.
other suggestions:
- enable KSM
- enable 16bit Dithering
- disable CPU rendering
- greenify your apps
If you follow these suggestions, your ROM should run absolutely smooth without the need for other tweaks.
To use Battery Life eXtender:
Use RootExplorer and go to: '/sys/class/misc/batterylifeextender'. Change the value in 'charging_limit' for example to 90 (default 100). This will set a limit for the capacity to which the battery will be charged. So in this example the battery will be charged to 90%.
----------------------------------------------------
After flashing the kernel whipe your cache and dalvik cache and fix permissions.
Just as a note. Should you encounter the white screen bug in some apps, this is because you whiped the cache in CWM Recovery after flashing the kernel. To fix this go into settings -> apps and delete data and cache of those specific apps.
Credits are going to:
- Arco (for his great work and sources)
- educk (for helping me doing the first steps)
- Christopher83 (for his great commits)
- ivendor (for his tweaks)
- Ezekeel (for Battery Life eXtender)
----------- 18.08.2013 -----------
- added frequencies
- incrased RAM
- lowered screen off frequency in Lulzactive
- some voltage finetunning

nicely done

I have tested this before with rc2 and I have to say battery life was very significantly longer compared to hurtsky 2.5 + QAsR v2.3. However, the white screen issue persisted in 2 of the apps I used the most, namely boat browser and Gmail so I have opted out again. But if you guys don't care about white screen, do give this kernel a try

Yeah, kernel 2.6 is always better battery life... i recomended it
- screen off frequency set to 768 MHz

What mean of that ?
is we get trun off the screen it auto lock on 768Mhz ? it's not deepsleep any way CMIIW

This is the max frequency the clock might rise to if the screen is off but for example an app or a service awakes the phone from deepsleep. So it will not drain so much the battery if the phone gets awake for some reason and if you undervolt your cpu, you can reduce the consumption for such a case even more.
This is preset in the Lulzactive governor, which Christopher83 fixed to make this working, so it´s only related to this governor, which is also my default governor.

So when in screenoff the phone only maximum can use CPU clock at 768Mhz
Yeah i get it. .thx for explain it

I think arco might be able to help you fix the white screen. Long back skull kernel experienced the same and acro helped him to fix it.

Uhm, well I´m not sure this is exactly the same because Keff (Woohooo..) is modding the 3.x kernel for CM10. But thanks for the suggestion. I will aks Keff first to not to bother Arco in the first place. It will be for sure interesting what caused it for him.
Just to clarify some things about the white screen bug. The one I described in my first post is not the real white screen bug, but only what happens to some apps after whiping the cache in CWM Recovery. This can easily be fixed like described above and will not bother you anymore.
The real white screen bug came all of the sudden (without whiping anything before). So for example you opened facebook, everything was fine, but a few minutes later by relaunching facebook you got a white screen. The procedure to get rid of this was the same as I already mentioned but with the difference it happened again after a while.
So well I have had this issue with facebook too in the past, but it´s gone and now even not happening after whiping the cache in CWM Recovery. It´s not gone because I updated the rom (still using RC2), but because facebook updated their app.
Edit:
I already found what you was talking about. It´s called the white noise issue where you get a white screen by turning the screen on, so it´s not the same.

Mind you: This is battery saving rom. It is meant to have low game performance. It MUST have a lower gaming performance than those v3.0 kernels. If you want gaming, this is not for you.

Yes, this is a battery saving kernel, but why should it have low gaming performance? Just because it´s optimized for low consumption in standby and because you can undervolt it? It´s like you were comparing an older Pentium4 against an Intel Atom CPU and saying the Atom must be faster because its newer. Or by comparing a Atom against a 286 CPU and saying the 286 will be faster than the Atom because the Atom is more battery friendly.
Sure, it´s not optimized to get the highest scores in benchmarks, but the games I´m playing once in a while are running totally smooth.
The newer releases of CM9 might be of course faster in games, but not just because of the 3.x kernel, but also because Arcos ocessionaly is updating the GPU drivers.

Thank you for correcting my ignorance. :laugh: Maybe I'll give the kernel a try and tell more about that

Honeyx, I hope you continue to develop and share this kernel in the future because I decided to start everything over from scratch because of your work here. I love this kernel. I get so much better battery life now. If you would ever consider adding Lionheart in the future, I would be very grateful. Is there any way to add Row or does it require kernel 3? Thanks again!

I may add some tweaks in the future, but this may take a while till I have some spare time to test them. About adding other governors...well I tested a lot of them but finally decided to use Lulzactive because it was the most battery friendly governor in the one hand and because there is also the Lulzactive app you can use to tweak it to your needs. So for example tweak it that way it behaves like for example Lionheart. I also tested the ROW scheduler but it wasn´t as stable as I presupposed to be. So the best compromise between stability and performance was to use the noop scheduler. It´s nearly as fast as the row but way more stable.

LoL. I´m quite sure with extreme undervolting you can still save some battery juice even while playing action games on this device. Beside this it´s not the CPU or GPU that consumes most, but the display and its backlight LED´s.

it is for battery saving but for me its not good to play with games cuz playing for like 40-60 minutes consume 60% battery ? lol
thats quite alot and might burnt up my battery life.

So did you thought it will consume just as much as being in deepsleep????????? The kernel is tweaked to consume less in deepsleep and in daily use but not to consume less in games. Beside this it´s not the CPU nor the GPU that consumes most, but the backlight LEDs in your screen. So even by undervolting and underclocking it will still drain a lot if playing games.
There is no and will not be a magical Kernel that is using witchcraft to reduce the consumption of the LEDs, exept someone compiles you a kernel which turns out the LEDs completely, if you can with a complete dark screen.

Im not expecting anything from ur kernel, im glad that u shared ur kernel taht could last longer than arco's stock kernel.
I was just giving up my comments about ur kernel that i have used for 2 months , Not complaining and whining lol.
I am sorry and thanks for sharing ur kernel , keep it up. :fingers-crossed:

[GUIDE] [ROOT] ExtremE Battery Life, ie Ultra power saving mode!

GUIDE TO EXTEND YOUR BATTERY LIFE UP TO THE LIMIT
20% Enough For A Day!​It is one of the best option if you left home with less juice, and are going to be in a trouble!
Yesterday, when I was on a trip with my friends, I forgot to charge my battery, and guess what: just 17% of juice left on my device at early 6 AM! So, I used this simple method, which I am going to explain down there, then while returning home at 9:30, 6% of juice was available!
The thins that I did was, listened to music for more than 10 hours (via earphones), Took photos for more than 15 mins (altogether), Surfed 3G for about 7-10 mins (on way back to home! ), and some phone calls!

App required:-
No-frills CPU Control: Most of the custom ROMs have this app integrated, but you can also download from Play store! https://play.google.com/store/apps/details?id=it.sineo.android.noFrillsCPU
STEPS:-
1. Go to No Frills Cpu Control or Cpu Settings(on most ROM's settings)
2. Select:
-Ondemand (Extreme Battery life)
-Powersaver/Conservative (Ultra Extreme battery, but laggy)
3. Tick Apply on boot and choose Apply!
4.Youre done, Enjoy ur maximum battery life!
-P.S: To have these governer, i.e. "ondemand/Powersaver/Conservative" you must be on Custom kernel bcoz, its not available for stock kernel!

well for your kind information all the governers (if have custom kernel) take phone to deepsleep while screen off. And as per your thread title i don`t think the guide is that effective becoz this governer thingy is known by almost every one here.Not trying to flame but just wanted to say that don`t open new threads for such known things.

stock kernel have 2 governor
bcm21553 and performance
this trik can be apply when we use custom kernel
i know about this long time ago

[Confused]which is the best rom and kernel for gaming??

I am currently in MIUI 10, but i experience frame drops even in low settings.
I want to know which rom and kernel are best for gaming.
With fastcharge enabled.
Thanks in advance ,Really confused!

go for No-Name kernel
(overclocked up to 2.2 ghz)
u can play pubg in Medium settings
I used MIUI Dev rom + NO Name kernel for 3 days (smooth performance + good battery life)

Wrong section, this post should be in questions or discussions
