I know that if you OC/UV incorrectly, it can cause stability issues. But I was wondering does it cause any damage to the phones hardware like battery, etc? And like how can you tell when SETCPU is causing problems?

Well if you OC to high numbers your just stressing the cpu more.Knowing when you have issues is simple getting random reboots,phone getting too hot etcc.
It differs for every phone but undervolting -25 for each voltages works well.
Personally I really don't see the point overclocking to high levels like 1.4 ghz etc,Is up to individual I guess.

Yeah I have been wondering what's the point of OC to 1.4? Does it make that big of a difference in the 4g speed? And cpu speed?
Sent from my LG-P999 using xda premium
Honestly, there really is no point other than for benchmarks. I, like mt3g, actually underclock the phone to something like 750-760mhz; it runs beautifully smooth.
Other than that, if you game a lot and want to maximize FPS, then overclocking would do that for you.
Doesn't have anything to do with 4g speed afaik. That's entirely reception.
Yeah 4g is about reception and tmobile simply.
I mean I had single core devices like MT4g ,SGS 4g for the most part on a day to day basis transitions to transitions theres not much diffirence in terms of speed. Now for FPS and a few other games you need that dual core.Point is there"s no need to OC a dual core phone!

I have had mine OC'd to 1.1 ghz with some undervolts. It is very stable , 10-12 hr battery with medium to heavy use , and ofcourse fast. Took a while to find the best settings.
When I have SetCPU set to 1015 megahertz, that's the same as stock voltage, isn't it?

Changes you might see are battery life but not that much unless you so how mess with voltage. Like other have said you know it effecting stability when its overheating, shutting down randomly, exiting program randomly.

I'm having an issue with my phone not being responsive if I set the CPU to 400Mhz. I first found this problem using Juice Defender then I uninstalled that and did it under SetCPU and it still did the same thing. The phone pretty much doesn't wake up after a while. I have to do a reboot in order for it to work again.
Don't get mad at me but IMHO overclocking and messing with a phones core features (what makes it run, processor, ram, etc.) is unsafe and can cause instability. And no I have no scientific research to back this up but it's just my two cents.

It does that under 800 mhz I forget why but I've read that in a couple places

underclocking that much is using less than 1/3rd of your true processor power.
your processor simply is not able to draw enough power to perform its background tasks - even when the phone is idle - when you underclock to such an extreme extent. therefore, it freezes trying to complete these processes.
if you're going to underclock, i'd say that 800 MHz is the lowest you can go if you are expecting your phone to do everything it is supposed to do. although it isn't going to save you THAT much battery life anyway, so you might as well just run it at the stock setting of 1200 MHz.

There's a known issue with setting CPU profiles to less than 800 MHz. A fix exists but some kernels don't have it.
Many of our Gingerbread kernels fix it, Infusion-GB is one of the few that hasn't pulled in the fix yet. (Although version 1.1 may have pulled it in, haven't checked github lately.)
None of the Froyo kernels have an explicit fix, but I'm not sure if the flaw even applies to our Froyo kernels as the clocking architecture is VERY different.
Hi, Rogers stock 2.3.3
It's using up 60% battery over night. Most likely I should turn off Wi-Fi.
I have underclocked to 100, 200, and 400 and it's stable --- minus the delay/lag at 100 and 200 . Sorry to seem like a troll.
I find that by default this phone either runs at 100mhz or 1200 on average, and 200 400 800 under 10%

Bumping from 100 to 1200 is classic ondemand governor behavior.
Also, some people never had problems even without netarchy's sleep patch running the CPU capped to 400 - but others have. I don't think anyone has had a problem with a patched kernel.
My Nexus S 4G seems to heat up very quickly. While I was expecting this behavior during excessive 3g/4g use, I was NOT expecting it while reading PDFs on my phone. I am using the built-in ThinkOffice to read the PDFs, but the phone always heats up after 10-15 minutes of use. Has this happened to anyone else before? If so, what is the solution?
Currently, my phone is rooted, with 2.3.7 stock ROM w/ Apoc-Talon v 2.1 kernel, overclocked to 1440 Mhz w/ Smartass v2. The heat problem has also happened while my phone was running a stock 2.3.4 ROM on the Netarchy kernel.
Its your kernel. I'm running cm7 at 1440 too and my phone never gets past 110 degrees Fahrenheit. Even while tethering which surprised me. When I tethered on my epic it would get hot enough to fry eggs. Even when downclocking to reduce heat. Just a hunch

Even if your overclocked it doesn't mean your gonna overheat. The CPU scales. Remember that. Its not like its running at 1440 all the time. Ive been running at 1440 ever since 7.1.0 came out with absolutely no overheating or lock ups.

You can't dispute what I said. Because you are able to overclock to 1.4 without issues he should automatically be able to? Are all cpu's equal? Take some time to think about it.

Of course. But that wasn't wwhat you said. You said overclocking needs higher voltages. Understood. I was only saying that the chances of his phone overheating because of ocing is slim. As far as I know only benchmarks and a few gpu intensive games will push the phone to run at 1.440 ghz. The CPU scales and barely even touches 1.2 ghz. Floats around 200 and 800mhz for the most part. I'm deducing this from my own usage and keeping an eye on the CPU with cpuspy. My point was that ocing wont do this unless he's actually pushing the CPU that far or setting the governor to performance. Which from the looks of it isn't the case

Now that I measured it with a battery app, the temperature only goes up to 107.6 degrees...guess it just seemed really hot to me.
Hi Guys I have a Galaxy S 4G I have noticed that max stable overlclock is 1.508Ghz If I bump up to 1.516Ghz It is stable but at watching videos for a long time it crashes, I have noticed that the normal max temp is below 60 C or 55 C, that's stress testing for long time, normal everyday is 41~43 or, I Think It can go higher but I t would need 1500mV or 1600mV core Voltage also to achieve 1.6, 1.7 or 1.8 even 2.0Ghz It takes 1600mV or 1800mV, temps would be 45~47 normal, and above 60~65 on stress testing. But tegrak doesn't support these volatges, It would need to tweak the code. With proper cooling temps can go down to 33 or 30, lets say using the phone in a cool room.
Do you know when are they gonna support higher core voltages(Tegrak OC)?
Do you really need to oc that high?

At 1.5 is goood but for proper PC like performance it would be a bit higher.
2.0ghz would beat samsung sgs2
I know anything higher than 2.0Ghz the phone would suffer, I don't know if the main board can support 2.5Ghz or 3.0Ghz. The battery doesn't handle that much power not even 3500mah battery
Mine runs stable and quite cool @ 1.62 and I get 4128 quad score, but I have no need to oc the phone with all the tweaks.

Thanks I'm gonna try out your setup, but that's the highest it can go?
I get a max of 2300+ because I have no tweaks and I am at Stock 2.3.5 UVUKJ3
I really don't see the need for oc other than for playing a REALLY graphical intensive game. For me, I get a better performance boost from the tweaks incorporated into roms than oc. I tried running a 1.5 for a week and I honestly didn't even notice a difference other than less battery life.

Well I notice a difference but anything above 2.0 GHz it is nearly impposible, even if it is gotten above that it would not match new dual and quad Core CPU because they have a different architecture but the battery is the first thing that you notice but the things that I do on the phone require much more processing power than stock. Well the highest is 1.6ish that I think the phone has been able to handle. But definitely overclocking the phone will get you up to speed work new games coming out

When we get source for GB or ics then I can write scripts to tweak the voltages higher for a higher oc, I have been waiting for that lol

Hi.
I a speed freak! If there is something I hate, is lag.
I therefore thought of using a better kernel for my G2x.
As I understand, some kernels can OC the cpu. Wow. That's cool, first of all.
Second - any conclusions about this? Is it safe? Does it really make a difference (i don't game on my G2x)?
THANKS!
Since you obviously don't know how to use the search function, I'll just tell you that it is perfectly safe to install a kernel and constantly run it at 1.5 Gh.
Go buy setcpu from the market to set your processor speed at Max, and leave it there. All the time. No matter what.

Haha, good answer..Or you can go and download CPU master for free. =)... But honestly overclocking is not good
There's no real speed difference when overclocking install a custom kernel but don't overclocking it its a waste of battery
Sent from my LG-P999 using XDA App
risks? yes. it kills your battery faster, and battery life will drop. by battery life, i mean the amount of recharge/discharge cycles it normally will allow will drop.
pros? makes your phone much faster. and no its not a placebo. if you bump up your kernel from 1ghz to 1.5ghz, thats obviously a speed increase. how can it not be faster.
Sent from my LG-P999 using xda premium
But also the risk at a constant 1.5 of overheating and burn out of the processor.
if you're a noob and don't know exactly what OC is, don't do that.
it can kill your battery and processor much faster, make you're phone unstable and accidentally overheat and burn out your processor, if you have a constant OC
processor life is worth the wait imo
I oc mine tops 1.2 and its as fast as it needs to be for my needs. I also bump up the minimal speed to about 500-800 cuz our g2x's should never be running that slow even when idle/screen off imo.

at the risk of offending you, I would not recommend setting your phone to 2ghz..I can assure you nothing great in the long term is going to happen. As for kernels give LordClockan and TalonAce a glance, I'm not 100% sure if they are 2ghz kernels but its a good jumping off point
2ghz will fry your CPU. Maybe not initially buy your phone will definitely fail prematurely. The only reasons other people do it is because they can and they probably have a newer phone for their daily. Even just overclocking a little bit can have a negative impact but not as drastic. If you insist on overclocking I wouldnt exceed 1.4.
With that said there are several Aosp kernels that will allow you to push it to the limit. Just search the dev forum.
Overclocking your cpu will not hurt it unless its running hotter than the cooling system can handle. It will cause lock ups and failure to boot. If you start overvolting it, you WILL cause premature damage to the chip itself. Optimum overclock has always been 10-20% increase for any processor. Personally id rather underclock and undervolt a little, runs cooler and less power drain.
gizmoe is right, 2ghz is a 'just cuz i can' overclock. it wont run stable at that level. its like the 8ghz overclocks you see on the intel processors using LN2 cooling lol.
2ghz is bad.
I ran my inspire at 2ghz and besides the battery practically counting down the phones was heating up and that was maybe 15 minutes. Definitely not a goods idea.
Thank you for the input and info guys.
I could over clock and undervolt on a past captivate. Is there any app you would recommended for the inspire on cm7 to do this?

Setcpu use to be the go to app but many found it to lag after waking the phone. Many have now moved on to daemon controller. From the looks of it you're using CM7 which has the function built in..I believe its menu > settings > CM settings > performance...or something like that...don't check set on boot until you know how much OC your phone can candle. If you like CM, take a look at Absolution by the Collective. They have scripts written for custom profiles for OC and UVing.

I've clocked to 2ghz a few times just to get a crazy quadrant score but that's about it. I usually keep mine somewhere in the 900mhz range with a little lite uv'ing and found that to be plenty.
2ghz can definitely be bad for your cpu..... Like to much bacon can be bad for your arteries.....
