[Q] Improvement :D

I use xperia x8 and i have nAa11 and 2.1.9 CM7... I have the processor speed, my minimum speed is 600MHz, 806MHz is max speed... I am interested in what else I can do or put on my xperia x8 to be a better, more beautiful or fast?

When it comes to speed, I think you have reached the X8's limits. There is only so much the devs can do - and for the record, they've done a far better job than SE (I guess it's just S now) will ever do.

Why 600Mhz for minimum speed? That will drain your battery very fast.. I have my minimum speed at 19Mhz and my phone is smooth as butter.. Your governor will raise the speed when needed.

Well, i have nAa too and no reboots at all. Because i don't overclock i also undervolt which also helps saving battery. One thing i like is the fact that phonecalls always use 19MHz
What governor are you using?

OC & UV limits

Hi, I'm tempted to push CPU beyond current 1200MHz, no Undervolting. I want to do a survey on what CPU frequency settings and UV hold you for daily use. :silly:

I'm currently using 1.3GHz/368MHz with smartassV2 governor. Good performance and good battery life on IceColdSandwich 8.2. At 1.4GHz or higher, it's unstable and the phone freezes while the screen is powered off sometimes.

I'm currently running 1420MHz with Ondemand governor, no UV, with no problems.

I thought the phone will start freezing when max freq is set to 1.5GHz?

I have my inc2 ocd to 1.5ghz on a daily basis , used to run cm at 1.8ghz daily with little overheating (nothing high enough to worry about), and I've also ran quadrant tests on cm7 at 2ghz.right now I'm running cm10 at 1.3ghz very stable.although sometimes in set CPU transitioning to a high freq like above 1.6 my phone would lock up but it seems like it happened only in ICS ROMs .idk hope this helps.BTW I never under or over volt

[Q] How to Reduce CPU brick when Over Clocking.?[SOLVED]

when i use 729 or above my Cpu stops working and its Reboot automaticaly any way to fix

Unfortunately you can't fix it. The overclock ability of the cpu is different in each phone. Some x8 can run on 800+ MHz, some can't reach frequencies over 700MHz. Basically the SoC (the cpu, gpu, dsp and some other device) contains millions of transistors, but the whole chip is only ONE small piece of silicium, the transistors made by litographic and other complex (and expensive) procedures. The overclock ability depends on the material quality (damages in the silicium structure), soldering quality between the core and the casing, etc. So, no existing rules to the overclock, if you lucky you can reach high frequencies, if you unlucky you can't overclock.
Note: under the manufacturing procedure the chips get a selection after testing, the highest quality 7x27 chips marked and sold as 7x27T with default 800MHz.

There is an app in the market called No Frills CPU Control: https://play.google.com/store/apps/details?id=it.sineo.android.noFrillsCPU
It will automatically change your CPU frequencies during boot to save your phone from hard bricking.
Anyway CPU gets overheated by overclocking as more amount of power comes in to it than what is required. So as a long term effect your CPU will die out and also your Battery too. So I would say to use a faster rom and dont overclock the CPU to very high frequencies.

You are using stock kernel?
Overclocking more than 729 is not possible for stock kernel...
Use "set CPU" application & remember to uncheck "set on boot "option
# I couldnt over more than 729 in stock kernel but now with nAa kernel in can overclock up to 787 mhz

governer also matters, I always use smartassv2

As someone wise already stated, better using something like FroyoPro which is blazing fast compared to any GB rom instead of overclocking.
I can do more with FroyoPro than anyone running GB, ICS or JB roms.
It's just simple - lighter code takes less cpu cycles therefore it is quicker.
GB, ICS and JB roms really are a waste of time once you've tried FroyoPro.
The other roms are really only good for proof of concept - not for everyday usage.

I tried it , it's not that much good:/ plus it have so many bugs with alfs kernel.(brightness bug for example)
I compared it with iXperia 8s rom before, froyopro is better @ one of 3d tests(just 2 fps better)
Other test were like iXpera & minicm7
Remember it's froyo & they are ginger ,they can run newer apps .
My opinion iXperia is our best rom till now

It also depends on the kernel you are using..Alfs is better in this aspect..but too much overclocking is not recommended.
if you are using custom kernel ,under CPU settings, select the frequencies you desire and do NOT select "Set on boot" . Even if your phone gets rebooted due to overclocking the default values will be applied at boot. This way you can avoid problems.
My X8 supports upto 787MHZ on nAa .
Hit thanks if i helped.

Just out of curiosity so upto how much can i overclock my awesome x8??
So far i've been to 729MHZ

It depends on the kernel you are using..some people here overlocked @800Mhz successfully while my X8 got settled only at 787Mhz. Try yourself.

its nAa N is next to B ;-D

At 787hz doesn't restart
Mine work at 787 hz smoothly,,,,it restarts rearly...remember to have an app advanced task killer ...and set its setting to auto kill after screen turns off..Also set it to crazy kill....
Hope it will help you....

please read 2nd post by pilu. that's the best explanation. it's a hardware limitation, and it does NOT depend on the kernel.
[cAs]

Partially depends from the kernel too. The cpu clock is not only a simple value: xyz mhz. In the kernel this is a little bit complicated (pll frequencies, dividers, multipliers, voltage level, etc). Different kernels use different frequency tables, the results can be different, this the developer choice who can set different bus speeds (axi, ahb), base pll, voltage to every clock speed. You only see the frequencies in the different kernels, what is same, but the same speed maybe generated with different method.
So, the cpu overclock ability is 90% hardware limitation and 10% other things. Usually if you reach your own max speed with a kernel, the probability of higher speed with another kernel is small, the typical difference is nothing more than +/- 1 multiplier (+/- 19,2 mhz).

[Q] Min CPU freq setting for low battery consumption?

Hi!
I've found this thread which explains in detail all Governor/Schedulers characteristics and much more.
Even if the thread is SGS2 based, there is one thing that catched my attention.
It is written that setting the min CPU frequency @ 100 Mhz actually takes more power during phone standby then the 200 Mhz setting because of cpu voltages...
Does anybody has similare experiences with the Galaxy S i9000?
Which is the recommendable min CPU freq for the lowest battery consumption during Standby?
Thank you!

it depend on devices n true voltage lacking when cpu standby, but its dualcore vs single core

200MHz is the best minimum CPU frequency for both performance and battery consumption for most cases. Leave your minimum at 200MHz.

you cant overclock from settings only one core. to overclock only one core u have to do a surgery to the cpu chip........
u cant overlock if the kernel does not support it. stock rom limit is 1500

Dude I just rooted my phone like 2 days ago so don't excpect me to be a pro at these stuff xD (I am a noob) But you didn't really answer my question tho :s

First,You need to install a kernel that supports overclocking, and after that you can use app like trickstermod or tegra overclock. But i would strongly suggest you to read more about rom,kernel,recovery etc. before asking such questions.

the phone doesnt have to do anything with the procedure u can overclock anything. from just a coffee machine to a kitchen , from a pc to a phone !! if a cpu has more than one core, u cant just overclock only one of them. I answered i told u the limit of the stock rom and kernel is 1500. u cant overclock. u must have a custom kernel that can support overclocking.
that means u need to unlock bootloader and flash at least a custom kernel if not a whole rom.
<<EDIT>> and just for the knowledge ! take for example samsung s3. it has a lower cpu frequency but the phone is little faster than our optimus. overclocking isnt only about rising the frequency. u can also overclock by slightly giving more voltage and faster correspondence. u have to read a lot to understand how it works. for example a mistake can make u have a slow 1700 cpu but a fast 1200 cpu. read read read read

set governor to performance, set cpuquiet to userspace. you need trickstermod app & custom kernel in order to tune this.

your cores are already at 1500. to set a perfomance governor to make them run permanently at 1500 will cause u a huge battery drain and cpu overheat. when u will go play a game the heat will enable automatically the cpu to rest so u will have actually around 1000 mhz speed. the cpu HAS to rest. the phones dont have many big fans inside to cool the board and the cpu. thats why people prefer ondemand governor usually. the cpu rests until the 1st core go to 90% usage or more and then the other cores are enabled too. when the cpu usage go below 90% one core is working again and when there isnt any need for cpu usage , the core goes down to 102 mhz.

overclocking
before you get your phone overclocked you should but in consideration that you may break your phone..over heating .... battery consumption.. don't look for performance alone >> you cant get performance with out battery drain or over heating >> just thing before you do that

You should look at how often cores 3&4 are even active. It's very rarely on my Nexus

ah c'mon he cant destroy the phone even if he wanted to. its not like he has the knowledge to decompile the kernel , change the proccessor limit to over 1700 and recompile it. so his limit is 1700 of iodak and werewolf and mokee. the thing is to understand how overclock works. he will figure it out eventually.

for the developers that know what to do , max for our phone is 1700. originally the safe overclocking at any cpu since many many years , is around 20%. after that it needs cooler. the better the cooler the more u can overclock.

Hi, trickster show me that my phone don't use the 1700 MHz. Y?
Sent from my LG-P880 using xda app-developers app

Probably it is not overclocked.
The stock higher operating frequency of p880 is 1500 MHz, and that is what your trickster diagram is showing.
So. Either your phone is notoverclocked, or in whatever kernel you are using maximum frequency is set to 1500 MHz.
