hi all, i sincerely don't know how to set no frills cpu control on my samsung galaxy S plus to avoid problems on frequency, don't have OC so max is easy (1400mhz ) but dunno what value choose in min frequency, can someone help me?
u better use 245mhz. try to install custom kernel with better governor.

Hello, I have a Vodafone 845. What is the default CPU speed please? And what would be the max overclock possible for this device?
Thanks,
Donald.
Install setcpu and see your default speed. You can try system panel also.
For overclocking, it depends, Temps and stability. Try to increase your clockspeed with small increases first, and go to the highest possible one with no stability issue. Just like you overclock your pc, you need patience and to be careful not to increase it to a point where you canot boot or spoil you processor.

[O3D] Overclock/Downclock guide/tutorial?
- can someone explane safe way to downclock(or overclock) GPU/CPU for O3D, I want to downclock to safe some battery life.
Thanks
SetCPU (search xda-developers for free download or market for paid updatable version) works for me, detected cpu speeds and allowed me to change them from 300 to 1008 Mhz, also there are a few options how the processor freq change when needed. For now you can only downclock until a new kernel arrives (not 100% sure what kernel is and if it really enables overclocking - just saying). I didn't try anything with setcpu but if you do please post your feedback
i have installed but i cant set the clock, with setvsel for defy i can define 3 speed for the principal status, in set cpu i see only the maximum rate (1008).
help me tks
Have you rooted your device, before you run setcpu?
what about downclocking, is it really giving extra life for battery?
I use Antutu CPU Master to downclock, it has a cool widget.

to what numbers you downclocking and how is battery life after downclocking?
Please advise me, what settings are the best for HTC Desire S (SHADOW HAWK V2.0|Sense 3.0|Android 2.3.5[2.10.401.8] ROM)?
Or give me a link where I can read what mean: VOC1, VOC2, VOC3, UV1, UV2 pages?
It's really not hard to understand,
VOC 1 2 and 3 are 3 profile of CPU frequency tweakers :
Here you can chose the governor and the frequency of the CPU
You can set wake and sleep governors, low frequency and high frequency.
With Hyperion kernel, i set
ondemand
245000
1152000
conservative
245000
614400
I don't know if you can OC/UV with a stock kernel.. Maybe someone can answer you better than me.
And it's really fluid and low battery eater.
UV1 and 2 are profiles for CPU voltage tweakers
CPU voltage tweak can affect the stability of the system.
The lower the voltage is the greater the battery life is.
I advise a -25mv every where (ALL -25)
But not more, i had stability issues with -50 and more.
I know how to set a cpu clock but I don't understand those profiles onemand, virtuous, conservative etc. Could someone explain me the diffrence between them?

if you are using stock kernel then you cant OC or UV
but if you use a custom kernel like Hyperion kernel you can OC /uv
VOC1 is for setting the frequencies
this is what i use
wake
governer: virtuous
min:384000
max:1228800(you can set it higher if you have any lag)
sleep
governer: conservative
min:245000
max:384000
press perm activate button
VOC2,VOC3 are like more profiles which you can switch to when needed
UV1 is for reducing/increasing voltage
if you are using hyperion v2.0 kernel you can uv by -50 (-25 if you have stability issues)
to do this press all -25 twice & then press perm activate
If you are going to change UV settings use the temp activate for a while cause if the phone freezes it will revert to stock settings on reboot
Sent from my HTC Desire S using XDA App
These are called governors. They control the way the CPU ramps up between the maximum and minimum frequency. Go to setcpu's website for a list of descriptions between all the different governor s
Right, setcpu homepage explained me everything.

Thanks Kartkk for the info. I am using the Endymion sense 3.5 ROM with the Endymion Kernel V2 on my Htc Desire S. Sorry for being such a noob at this but just wanted to ask you lot soemthing. Users on that forum somehow seem to get Quadrant Scores of over 2000, I only manage score upto like 1750 with the settings you have mentioned above. Please Advise.
Thanks in advance.
I'm running a pre-rooted, deodexed 2.3.5, and have now tried 2 different kernels (unity and hyperion) and while I can make changes in SetCPU, I'm unable to alter tin UV settings in UV/OC beater because the kernel doesn't allow it.
Does anyone understand why this might be? X
Default undervolt values
Can someone please post the default undervolt values for the respective frequencies. I want to set back my phone to the default voltage. Thanks allot
OV is risky business if you ask me
I have htcdev unlocked DS (after ics ruu) S-on,...
I guess that some kernels allow UC/OC and UV/OV but some don't. I only tried two diffident roms fallout v5 which allowed both, but now I running finnys JB 4.2.1 rom which allows only UC/OC but not UV/OV(according to pimp my rom app).
Benchmarks cores; fallout5 antutu score: 4600, JB antutu score: 4050 but JB runs faster, smoother, slicker
And if you cannot find default values just restore nandroid backup image, and then look for values there.
Hi,
I am fighting against a problem with interactive cpu governor. For some reason cpu frequency gets randomly locked to any value. Rom is Android Revolution HD and kernel is faux 8b9. However, this has happend with older kernels & roms too.
Any ideas ? Familiar issue to anybody ?
Thanks !
"No-Frills CPU control/Pimp my Rom" for different speed governors and I/O schedulers
The custom Kernel for A110 is coming. But till then, you can try out some different clock settings to get you more speed when on games and experiment with speed governors and I/O schedulers with the stock kernel.
Install No-frills CPU control or use Pimp my ROM to change the Min clock(limited to 250 MHz) or Max clock (limited to 1.001 Ghz now) and 5 governors (ondemand, userspace, powersave, hybrid, performance). For optimal battery and speed use ondemand with 1Ghz/250Mhz and noop scheduler. For games, try performance governor. Those who want maximum battery life can try powersave governor....

lol..its useless on stock kernel.bdw each and every kernel can be underclocked.

I think you have not read the post correctly. See the heading...Its not for changing clock speeds...Its for changing governors and I/O schedulers and there is no way you can do that on stock ROM without an external application as there is no settings for that in the stock ROM. And I am not taking anything about overclocking dude And many of the end users are beginners who do not even know these things...
I have clearly mentioned that the highest freq is capped. And it is not useless. We can play with the governors and the I/O schedulers. Read before you comment pal
but all are useless in stock kernel.ask varun if u have any doubt.

You are totally wrong dude..Get your info right. I have been playing with android right from 2010 and have used a multitude of phones Am not a beginner...I do not have to ask Varun on this...Default kernels come with limited speed governors and I/O schedulers that I have listed above, and THEY DO WORK...When you modify the kernel using sources, you can add many more governors and schedulers and also add other functionalities like over-clocking. Think before you post pal

Read this dude....
And for your knowledge. The default governor and scheduler that our A110 comes set with is hybrid/cfq. That gives the maximum quandrant score of 3000 and above. Try to change it and you will see the difference in performance. The quadrant scores will go down. The settings DO WORK and to get better battery you can compromise on the performance.
Cheers....
m also not new in android..i also used too many android phones.

You mallu?
same here, expand what you are trying to say?
o/c not possible in stock kernel, but yes we can set clock values depending on the stock clock values between 0 - 1ghz (min 250mhz / maxx 1ghz), and even set governers, we need root for doing such actions na? but not possible without root!!!

so can you give me a clean explanation of everything u said on the 1st post?
Yup..plz explain dude.:angel:
in the stock rom/kernel , what settings in "no frills cpu control" is the best for performance and battery respectively ?
the options seen are governors ( userspace , ondemand,hybrid, powersave , performance ) and I/O scedulers (cfq , deadline, noop) ..
will changing these options be effective in the stock kernel ?
