SetCPU safe?

Doesn't SetCPU overclocks our device? I heard constantly overclocking your device will kill it less in a year. Is this true?

I used setcpu on my g1 (overclocked from 384mhz to 528mhz) for almost the whole time i had it and it didnt do any damage. The overclocking on snapdragons is more of a wait and see as no one has overclocked a snapdragon for that long but its HIGHLY unlikely that it will kill your cpu that quickly (ive been overclocking devices for years and never seen it happen). Leo users dont need to worry about overclocking with setcpu as it hasn't been enabled in the kernel we are using so the only thing setcpu is good for is underclocking and setting profiles.

So once it is enabled in our Kernel that's when we should be worried? What's the worse that can happen?
Thanks for the reply.

I dont think we should, people on the n1 have been doing it for months and i havent seen any posts of things going wrong and even if it is enabled in the kernel you can choose weather to use it or not via apps like set cpu

I know I use it to underclock. I was just saying. I actually use it as a means of making the battery last. and also the reaction time at which the cpu scales.

So if I understand this correctly, setcpu does nothing to improve performance as far as Device speed?

A faster cpu is generally a speed increase and at certain points the gains are null. so its usually a small mhz boost.

it does, keeping the device at 1ghz (998mhz in our case) at all times will provide better performance than scaling from 245mhz to 1ghz. read here for more info http://www.pokedev.com/setcpu/

[Q] SetCPU for MT4G?

Is it safe to install SetCPU on the MyTouch4G now that we have permaroot? If so, what are the settings we should use with it? Just not sure if the current kernel has been tested with SetCPU or not, and if it works what version of SetCPU... 2.0.3 or 2.0.4?
Thanks.

I am running 2.0 4 with autodetect. Set at 1024mhz performance. No issues and been running 3 days now.

So you're not overclocking it then, correct? What is your setting for the minimum frequency?

I have it at 245mhz.

set up a profile under screen off and set max down to 3000 and minimum at 2000...saves me ton of battery power now
also download auto killer memory in market and set to optimum for even better battery life

I thought that over clocking required a custom kernel?

The closest options for this are the following:
368640 max
245760 min
What did you use for the scaling and priority settings?
EDIT - Added a screenshot to this post. I've tried both 2.0.3 and 2.0.4, and no matter what I set for the minimum setting it stays at 245 (not what I defined). Does it not work then on this stock kernel?

I was going to say the same thing, from what I have seen on my phone setcpu is not doing anything. It won't change any of the clock speeds whether boosting the low end or limiting the high end.
I have tried a few things like setting profiles for less than 75% battery to lower the max clock speed and that doesn't work either. Am I crazy or are others experiencing a placebo effect on profiles lowering clock speed when screen is off?

For HTC phones need to be rooted and also disable perflock. In setcpu: menu->perflock disabler. I set my perflock to disable on boot.

Hot damn, that fixed it! Now to test it out further to see how well it works here. I'm not looking to overclock, just underclock when I'm not using the phone. Thanks for the tip!

Just an average power-user. I email and text a lot as I own a consulting business. I am constantly on the go and need my battery to stretch as long as possible.
That is why I kept the stock kernel and didn't over-clock. I simply removed all the bloatware and non-essential apk's that I didn't need and set up a few profiles in SetCPU and now I can get an easy 2 days of power use out of it.
As I still employ the stock kernel and stock ROM I have no lag what-so-ever. Response is perfect IMHO.

SO I am new to this... I used your same settings and my bat shows 56%. On the my screen it still shows that its jumping from 1024-245. Am I missing something?
EDIT: N/M I am just dumb and forgot to preflock!
So I set my profile to have
Screen Off Pri 75 Max 3K Min 2K
Bat 75% Pri 50 Max 7K Min 2K
Bat 50% Pri 50 Max 3K Mn 2K
I will let you know how it goes but I am hoping for some good bust in bat life.
Had some issues when waking the phone, so I changed the settings on the screen off to Max 768. Going to test.
I also moved the 50 Bat to 30 and still getting good life out of it.

Well I have been experimenting with some profiles in setcpu and I have noticed a great increase in battery life especially when in standby a lot.

So i have done this according to what works for everyone else. But... my battery still drops from 100 down to 40 in about 5hours and it has been this way since the 2.2.1 smh. I dont kno what to do. I do text alot and get on facebook mobile semi frequently but mainly text and omg the phone gets up to 104 degreez wen using or charging. Any suggestions ? Or anythjng i may be doing wrong

I have noticed that Set cpu bind very processor! Try to uninstall and install this program: Temp+CPU V2
Link: http://www.appbrain.com/app/temp-cpu-v2/com.sanels.tempcpuv2
...and see that its processor to work at low levels ....

Mordon2008, I guess you're trying to say that setcpu is using a lot of cpu power? Which I don't think it does when you configure it correctly. On the other hand, if you're using a build/rom/kernel that comes with a smartass governor by default, it is true that setting up setcpu wrong might even give you a worse performance than not using setcpu at all, because it already handles energy saving during sleep and interactive scaling during load very well from what I understand (somebody please correct me if I'm wrong). Therefore, my answer would be that it depends on the build/rom/kernel you're using.

Personally, I don't see the use of SetCPU on NAND builds to be honest, unless you're looking to overclock your CPU (when available).
I'm not using SetCPU and i'm on my 3rd consecutive day without charging the phone. (30% left).

I'm not playing with the phone the entire day. I have more important things to do..like work
I 'stress' the phone maybe 40 to 45 minutes a day during travelling to work. And all that stress is the internet connection and the music player
apart from the occasional calls i must say it's holding up well.

That's actually what I was going to add... I think there's at least one use for setcpu even with the smartass governor. I myself am using it in order to restrict the maximum frequency to about 768MHz. For my purposes, this is enough and does not make the build I am using less snappy. But it might save at least a little bit of energy and therefore improve my battery life a bit.

SetCPU vs. CMSettings Built-in CPU manager

For those of you on CM7 (preferably RC2 or later nightlies), are you using SetCPU or the built in CMSettings CPU manager? Which is giving you better performance/battery life?
I can't help but think that the built in CM Settings CPU tuner is going to be conflicting with my SetCPU profiles.
Been using nightlies since #30 or so, and I currently run SetCPU with a normal profile, a screen off profile, and a profile for <10% battery and haven't touched CMSettings' CPU manager.
I'm contemplating just uninstalling SetCPU for a day or two and seeing what a 1017max / 245min Ondemand or Powersave governor via CMSettings ends up doing to my battery life considering there will be no screen off profile.
Any thoughts?

I dumped setCPU after a lot of testing (and even bought it on market)
I'm finding I'm much happier using inbuilt CPU settings. I think battery life is the same but performance is better due to the fact that SetCPU would sometimes get stuck in my screen-off profile when turned on causing the phone to be really slow.
I recomend uninstalling setCPU, set your ONDEMAND governor with ~1Ghz and run it... You'll find your battery about the same but much less hassle.

I have yet to try that, I somewhat feel obligated to use SetCPU since I purchased it lol. But it probably won't be the last time I waste money at the market.

Neither. CPU tuner works best for me.

its the same thing :facepalm:
Try the inbuilt one... I think its way easier

I've been wondering about this too. I don't quite understand how it works. Can I just set the frequency higher till a certain point without changing the voltage and get the same battery life?
What's the best way of doing this? Just change the clock speed or do I need to change something else or update the kernel?

Whatever you tell SetCPU to do, you'll see the same settings mirrored in the CM settings.

I say setCPU cuz as battery gets lower... I have my CPU speed lower also. Basically, 15% battery lasts me forever :] lol

Definitely. This is the one thing I like about SetCPU is having the 10% and 5% profiles so that I can get the last few % to last forever if I need it. Although in normal day-to-day use I'm never pushing it below 20%.

Yea I see this, as far as the governor changing etc.. This is why I'm wondering if it would be easier on my phone to just run only the CM Settings one.
I notice that every 5th or so time I unlock the phone, there is an obvious lag switching from the screen off profile, and my unlock sliders jitter around and it takes 4-5 tries to unlock the phone. I think this is probably partially due to both settings switching over trying to change.
I think I might try backing up and uninstalling SetCPU for tomorrow to see how it goes.

I've read on here that overclocking the Vision's CPU up to 1 GHz requires no over-volting, and in theory should not affect battery life (but not sure exactly where that information originates from). But there has been lots of debate on these forums on whether the SetCPU app helps or hurts battery life depending on screen-off profiles (underclocking to save battery) or its constant polling of the CPU clock (possibly killing the battery faster).
A kernel that supports overclocking is already part of the CM ROM. If you are on CM, you can just adjust the clock speed under Settings>CM Settings>Performance>CPU settings. Or set the CPU clock using an app like SetCPU. Choosing one method over the other is what is being asked/debated here. If you are on the stock ROM, you need to be rooted, flash a custom kernel that supports overclocking, then install an app such as SetCPU or CPU Tuner to set the CPU clock to your liking.

I'm not sure about CM's kernel with the over-volting but I do know that Pershoots kernel can be overclocked to 979mhz without over-volting (Pershoot told me himself).

At 1.8Ghz, I find the temp settings in SetCPU very useful.

Well obviously.... But why the hell would you ever need to be running at 1.8ghz? The fact that you are always using a temp-specific profile method should show you that consistent 1.8ghz isn't good for the phone...

Okay so I uninstalled SetCPU last night and I'm going to run just the CM Settings CPU manager all day to see how it goes. Running like this:
ONDEMAND governor
Min CPU: 245 mhz
Max CPU: 1017 mhz
On nightly #19 also.
Okay so its midnight almost, and I'm at 13hrs unplugged and 52% battery still. Pretty general/light use, phone is just as snappy and the lack of a screen off profile doesn't seem to effect battery at all. Liking it so far! very interesting to see the screen off profile not mattering much.

SetCPU for me. I like to have a temperature and charging profile, to prevent the phone from overheating. Even at 1ghz the possibility exists, nice to have a backup incase.

I'm thinking set cpu conflicting with the cm built in caused my ****ty running problems. I have not used setcpu since and been good so far

With multiple tries... If you change the settings on one, it cancels the settings on the other... Maybe it's because you had set on boot enabled on both?

im going to run the CM tuner and uninstall Setcpu and see how it runs. i never thought about this but i do get that lag when i turn my screen on sometimes. im gonna miss having the profiles but ill see how it runs over the coarse of a couple days.

Overclocking ROMs heat issue?

I am going to be getting an Atrix in the next few days and will install the Aura ROM right off the bat, but im wandering, since it appears to use an OC'ing kernal, what effect will this have on heat and battery life? presumably negative, but how much so? i dont want another phone which heats up like mad, but i do like the look of the ROM. please help out an Android n00b
thanks

Just because it can overclock doesn't mean you have to. I use set cpu and keep mine undervolted and set to 1.1ghz. Idle around 30 celsius and when I game it gets up to 50 degrees.
Sent from my MB860 using xda premium

the atrix on stock 1.0 ghz gets REALLY hot so yea i would assume it would just get hotter MUCH hotter but you can get a setcpu and just set your processor down when you dont use it much or make profiles to automatically do it

great, so the rom just allows OCing, not forces it? thats good to know, thanks

it will automatically clock itself to 1.3ghz, you'll need a program like SetCPU or PimpMyCPU to set it to not OC itself.
i suggest SetCPU myself, it can be found on the market. i prefer buying it over getting it for free here on XDA, we gotta support our devs right?
