How can I change the speed the CPU is running at? Setcpu won't allow me to go over 1ghz even with Tiamat 1.4.4 @ 1.7ghz kernel. Newb question I know...
Did you turn on autodetect?
Did you allow setcpu in superuser.apk?

[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.
Am I wrong in believing this ROM comes with an overclocking kernel? I know in the D2G Development post for the MIUI 1.10.21 ROM, Aceoyame stated you could set the CPU speeds/voltages in the bootloader, but any settings I change there don't seem to change anything in MIUI or setCPU. My setCPU 2.2.4 still won't allow speeds over stock 1200MHz, and there is no smartass governor option in setCPU - just ondemand, userspace, performance. I have tried autodetect and 'show other frequencies' several times, nothing. Is there a setting I'm overlooking, something I need to install?? Is setCPU just reporting the wrong speeds? I've searched for related threads and can't find any, hopefully I haven't missed them... Thanks everyone
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 world,
I am wondering what program you guys use to overclock your tablet? Or what procedure? I am currently at ARHD rom with ICS test 21.3 kernel and am wondering what clocks do you guys use - suggest also some UV list would be great
thanx
make love,
miHah
apps to control cpu speed
use: set cpu (paid) or nstools (free)
Ok, what about schedulers? I installed setcpu and its on "sio" ondefault. Which one to use and when?
I don't like setcpu, or any app to oc for that matter. When I was on ARHD (and therefore had to use an app) I used No-frills CPU control, not too many bells and whistles and worked.
I highly recommend 'interactive' for a performance governor, it's easier on the battery life than performance and snappy.
Default scheduler with wifi off during sleep tweaks is fine.
I use 1.4 Clock at home and 1.2 out and about, but you can probably go higher if you want, 1.2/4 is plenty fine for me though. (I keep my RAM really free though, I feel that is more important. IMO)
