Safe under and overclock for Desire Z?

What are the safe/stable clockspeeds for underclocking and overclocking my Desire Z? Also, what app do I use? Like, I don't mind paying for the app (as long as it's not too expensive)

SetCPU can be used to overclock if you're rooted. Depending on the ROM and Kernel combination, overclocking to about 1.3ghz is usually safe. Some go up to 1.5ghz or even 1.8ghz, but are often quite unstable depending on other configurations you have in your ROM.
As far as underclocking goes, some custom kernels clock all the way down to 122mhz, I've been using a streamline5 kernel on CM7 (which offers 122mhz min) and haven't had any ill effects with this.

I have the Virtuous Sense ROM (with it's default kernel, although it does have other kernels which can give other cpu speeds), right now but might try out another ROM soon (maybe) do you know what's the min and safe max for this ROM?
Also, can I just set a particular clock speed (e.g. 500MHz) and it should be ok or is there any stability difference between say 500MHz and 505MHz? Just curious. I looked at SetCPU and it looks like a good one. Also, if the clock speed I set makes things go wrong, can I revert it or can I get stuck with it and need to do a wipe?

No, there's no need to set a particular clock speed. Just whatever works for you. I wouldn't recommend going under 800mhz, as the phone will really really bog down even with normal use.
I haven't used that particular ROM, but I'm assuming anywhere around 1.3ghz should be safe on the upper limit. Like I said before, anything above that might start to cause issues. You might also want to consider the battery life implications of severe overclocking.
You can change the clock speed any time you want. If you're having wakeup or heat or any other issues just go back to SetCPU and change the max clock speed again. You can also use profiles in SetCPU to change the clock speed when the phone is overheating, or when the screen is off, or when the battery gets to a certain %. There are tons of posts detailing how others have setup their SetCPU profiles.
One last note, don't forget to check the box for "Set on Boot" in SetCPU, this way your changes aren't undone on reboot.

Thank, I think I got everything I need to know in your last reply

I'm on CM7, with the CM7 kernel, and clocked in at 1.5GHz, and have no problems, and the rom is super fast. And I use SetCPU.

Best SetCPU Config for Desire

Hello
Does anybody use set cpu with HTC Desire ?
I would like to know wich settings work the best for you. I am trying to get the best compromise between battery life and performance.
Thanks

128MHz - 998MHz ondemand. I get more than enough life out of it. I found that if your using AOSP and not really doing much on it like just texting or calling people, capping the max to about 600MHz or 500MHz if you want, works a dream and you get even longer out of it.

Smartass is better or worse ?

I do not see any real difference between smartass and interactive in term of battery live and performance.
On demand seems to drain slightly faster than smartass.
I set my Desire to 384-1136 with interactive govenor.
I charge it once i a day each time before I go to bed anyways (sleeping time usually23.00 - 05.00), so further battery saving is not necessary to me
Edit...my normal usages are:
Syncs (no auto sync by opening):
Friendstream 4 hrs
News 4 hrs
Weather 6 Hrs
push Yahoomail
push Googlemail
push Whatsapp
push EBuddy
Active background :
Lookout antivirus
No app killer used
Phone calls : about 1-2 hrs each day
Music listening mit DSP add-on : 4 hours
Fruit ninja (man! this is addictive!) : 1 hrs
Browsing (Dolphin HD + Android market) : 2 hrs
welll....every time I charge my battery it is about 15-25% left till out of juice...if I use my phone more than those, I have to charge it earlier (more than once a day)

245 - 985 MHz Conservative give mere 36 hours power and running smooth.

For me the battery has never lasted more than a day... Even on my un-rooted one...

BTW: Battery live depends on many things
1. Your ROM and kernel
2. Your runnning application, syncs, etc.
3. your usage and settings such as cpu freq, display brightnes, airplane mode, etc.
4. Received signal quality.
5. The condition of the battery...is it top fit for example?
It is difficult to measure the battery live.
@atuladhikari : battery live has nothing to do with rooting..

I don't like using any of the other governors since I get lag. I hate lag. OnDemand gets rid of the lag for me. I've had it before where I was using smartass and it took ~30 seconds for my screen to turn back on from idle. I wasn't too impressed.

setcpu
thanks meaple for your advice
i think that set cpu is fine on "ondemand" for some roms and for others roms no
set cpu is included on oxygen settings and running well

Cool, I need to download Setcpu

128-998 ondemand
screen off 128-384 ondemand
in call 128-384 ondemand
I get very good battery and performance with theses settings.

Which app do you guys recommend? Tried overclock widget doesn't seem to be working.
Am on Insertcoin stock GB rom.

DidI do that?....I did.... LOL.

I used to use set cpu
set a profile like
Smartass
on charge - 1113mhz
80% - 100% - 998mhz
59% - 79% - 600mhz
35% - 58% - 500mhz
Screen Off - 300mhz
Priority was higher for lower battery %
BUT I stopped using it because of the little bugs, like when it changes to 384mhz for no reason after unlocking screen
It also affects the standard script with the rom you install, so you can never uninstall it properlu, you have to do a full wipe install and never install it, until I did that my phone was always a little laggy
I prefer my phone without it Each to their own

@shankly1985 - you didn't noticed wakeup lag with 128 MHz?
I must use 245 - x MHz to properly and fast unlock my phone.

Best Setcpu config for Desire is - no Setcpu at all.

I couldn't agree more with you. Experienced all of the above so no go.

245-1033mHZ with smartass give me two day out of my desire loaded with insercoin 1.0.9 with v06 kernel !
I am mostly sending Text message and some calls.

Not at all mate, I get zero lag on my phone. when I check the info on the setcpu app and time in state 128 is at 85% so my phone is using very little cpu.

Do we need SetCPU apps when we have CM 7.0.3 Stable ?

I am a newbie on rooted phones. Just rooted the phone to CM7.0.3 Stable and found out that we have a setting to change the Govenors, currently set using SMARTASS with 245/729.
One question, is it nessesary to install apps such as Setcpu to overclock? or it is just adequet to use the setting in CM7 ? Will both conflict each other? Many thanks

Its useful I think, because you can setup CPU speeds for certain things, such as when your screen is off or when the battery drops below a certain threshold.

depends on you need dude. playing games/ watching videos/ hearing music/ simple phone usage/ battery conservation etc. stock one dont have profiles. but 3rd party like set cpu have it. so that it auto switches profiles according to ur present phone status.

SetCPU is much more useful than the cyanogenmod CPU functions, I did use the cyanogenmod one but I didn't see any changes

yes, the good things are the profiles! but I'm not sure if underclocking the processor really saves battery since i've heard that its just a saying/placebo

Yeah I think your right, strangely enough I think it's the same with overclocking, I put mine up to 700ish MHz and the battery still lasts just as long, I expected a reduction in battery life!

[q] htc wildfire s overclock

I have htc wildfire s ...i hav rooted ...i want to overclock it 806 mhz.....pls tell me the procedure to overclock..
I am using htc wildfire rom ..pls help

First you need a kernel that supports overclocking.
If you using a stock Rom then look for the kernel that matches your Android version eg. 2.3.3 or 2.3.5 you will find them in the development section posted by Jikantaru
If you install a custom Rom then it will most likely have an overclockable kernel baked in.
To change clock settings I recommend 'no frills CPU' search it in the market or you could use set CPU.
Once you install one of the above apps then change the min and max sliders to the desired frequency.

if we over clock it much does it effect the speed or hardware of the phone?

Your phone may hang.
There is SetCPU for XDA members:

You will definitely get better performance and it shouldn't cause you any problems.
Use no frills CPU I find its better than set CPU, when restarting your phone set CPU doesn't keep your overclock settings even though its set on boot.
As for the govonor settings I would choose smartass2 and noop for the scheduler.
I would keep the minimum frequency on 245MHz it can go lower but it could cause some issues (lag and slow unlocking and waking)
Note: not all cpu's are capable of running at the same speed, I'm lucky mine can run at 806MHz but some people have issues.
If you notice any problems like freezing etc, then drop the speed to a lower frequency until you find the sweet spot for your CPU.

I had mine at 806 MHz with no problems

so it wont cause hardware problems only lagging and other stuff

Should be fine mate.
But remember if in the very unlikely event something does go wrong I wont be held responsible.

youll have to need an overclock kernel for that. (and a rom which supports one)
go for dust kernel or cake kernel! These two are well known for high end kernels!

[Q] super heating.... I'm confused

This is the topic at hand .... not that after a period of use the lg nitro hd p930 is heated in an incredible
way and this caused the system is damaged and the wifi did not work because of this I had to unbrick the phone to
install them other rom that doing ics hard reset on stock 4.0.4 att ... but I just realized I still doing the same in other
rom and you do not and I hope that someone knows about this and can give me an answer.
Note: this step after aver played Turbo Racing League now all I installed rom without playing is heated and the wifi is
going to turn off and remove and replace the battery
excuse my bad English use google translator

Try to change frequency. Standart is about 1500mhz and you should decrease it to 1200 or less. Use set cpu or cpu master (free in google play).

No Frills CPU is also free and available from the Play store. I use SmartassV2 and Deadline in the cpu settings.

thanks for the info ... I cofigurado yesterday with the minimum frequency to 460Mhz and 1000Mhz the Maxima using the SetCPU program ... My concern is that if this resolves the wifi is not active due to heating after that I have to wait for the restart and pull the battery to get it working again ..
If you have further information about the settings they are appreciate ... I'm using the Rom Avatar

You could try installing an ICS rom to see if wifi works. If it does, then you know it's the current rom that is causing the problem.
I have tried a few roms and never had the heating or wifi issue.

not that the wifi does not work is that when heated or I'm using and gives the restart issue is not working anymore for some time

Not sure but maybe there is something wrong with your phone or the battery. Does the battery heat up when connected to a charger and sitting ilde? Does it heat up just sitting idle and not connected to a charger?

This is happening with regularities in these devices and as I see on forum ... is when I'm using a heavy application at first but after was more consistent than using normal applications gives Random restart

I think I read one or two posts from people that had hot batteries but that was due to the person using a custom rom.
I started using my P930 after not using it for many months because I was using a different phone. I loaded CM10 because it seems to give me the best battery life so far. I'll know more when I start using the phone more regularly.

In my reason I have determined that the problem seems to be hardware that is not heating the battery but processors am using Avatar Rom Android version 4.2.2 based on CM10 ...using wind kerner 2.5...And as I have read it is the cpu frequencies...download an app to adjust the frequencies at the same level...commented after what results
