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.

Lol I'm not mad. I don't really like to over clock. I just figured under clocking would work better. But nooooo lol

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.

So I found a kernel on the Fascinate forums that was built off of our EC10 froyo source that was from nemesis2all and I saw that he had added the ability to overclock and undervolt from within the ROM so I installed it just trying (backed up of course) and found that it does indeed work.
I then got the Voltage control app from the market and started playing around doing Quadrant scores throughout after each change. I found that at 1200 mhz I was getting 1600s instead of 1400s and the phone ran great. But when I tried 1400 mhz the phone froze up and restarted while doing the CPU section of the Quadrant test so I reverted back.
My question is, what would be safe to stay at for general use?
Second question, how do you use the voltage app to undervolt I see the settings but I don't know what to set them too.
Here is the link to the kernel
1200 has proven to be the most stable overclock, any higher and it will freeze up eventually.
With voltage control, the way it works is that you set the max clock and then it will give you increments that the phone will automatically clock to within the guidelines you give it. Then for each increment you can set the voltage it will use. Just look around and experiment with voltages, see how low you can go without having issues and never set it to apply at boot unless you know that's what you want, other than that go crazy and a reboot will fix it if you have a problem.
I recommend keeping setCPU installed along with it, that way you can still force it to underclock or overclock or whatever. It all depends on how much you use the phone and what for.

H'm, I tried going up to 1.3 and it would freeze up after 5 or 10 minutes every time.
Like I said, 1.2 is the only one that has proven to be safe for everybody... not each phone is exactly the same and if akellars CPU has a soldering that is done a little bit different than mine, it might allow him to clock a little higher. who knows
Sent from my MIUI SCH-i500
I've been running it for a week @ 1400 -25 undervolted and haven't had any issues. The new 1.6 gives me trouble. I don't think there's enough overvolting in that one to make it stable for pretty much anyone. I use the 1400, 800, 400, 200 steps all undervolted @50 except 1400 which as mentioned is -25. Battery life is good because during sleep it doesnt really hit the high end and by not having the other steps its snappy when in use. Fastest this phone has been by far. I don't use setcpu because I think it and the voltage app conflict. That was nemisis's instruction to install it.

Yup I'm just lucky 1.4 worked for me too but I didn't see much of a performance difference so I didn't see the need to stress the cpu out anymore than I already was. battery life had been awesome for me with my setup as well.

Do you overclock or underclock? If so, to what point? If not, why not? What clocking profiles/situations do you have set up? Share your thoughts and experiences.

EDIT:
Below is the setup that has worked best for me, in terms of performance and battery life. I seem to have found a good balance.
1.2 GHz/245 MHz (Conservative)
Profiles
Screen Off - 768/245 MHz (Conservative)
Charging - 1.2 GHz/245 MHz (On Demand)
In Call - 1 GHz/245 MHz (Conservative)
*Profiles are ordered in terms of priority (e.g., if I am on a phone call and my phone is charging, the charging profile is activated).
*I'm also undervolted.
I keep my phone at ~.7GHz (underclocked) when on battery, 1GHz when on charger, and have profiles for medium (~1.3GHz) and max OC (~1.7GHz), as the kernel will allow, in case I need the extra power for something (like FPSe, chainfire, etc).
I keep mine at 500Mhz...gingerbeast is so beastly it can run decently even at about 200Mhz, I only use maximum...1900Mhz when I am showing off.

Damn if it doesn't. Never tried it but since you said it I figured I'd test it. Typing this this at 245mhz, and it actually functions decently, even scrolling this page. I tried this with my captivate and it wouldn't even swipe screens. I'm kinda amazed right now.

Im at 1344mhz daily with absurdly outstanding battery life on leedroid 3.1.1. And I'm using antutu CPU master cause setcpu wouldn't let me adjust the slider. No problems whatsoever.

Before my phone got jacked "another on the way" i run TPGB with ~1.5ghz top and .232ghz low. Smartass govener, and i use my phone alot. I easily got over a day. Thats with tethering-games-email-calls-messaging,

I was running at max OC (1.8Ghz with LeeDroid's kernel) for a little bit, but realized I didn't need the speed. Since I'm a PC overclocker as well, I couldn't just let things be at stock, so now I'm at 1.267Mhz max, and .245Mhz min. I'm doing my best not to bump it up more, and going to see how much I get out of my phone. I'm a very light user most of the time, so it's sometimes hard to gauge.
I overclocked for the same reason I OC'd my PC, because I could. That said, I'm running MDJ's kernel on Inspired Ace with the smarta** governor set at 245 min and 1400 max.
Seeing several people using smartass governor. I've been using ondemand....I'm gonna run smartass today and see what happens....

Mine is at 768 all time, with just one profile that kicks when battery heat crosses 46 C that sets max speed at 537.
Adjusted both to 614 and 384 respectively after looking at above posts.
OC'd and [email protected]
using setCPU and being on CM7, i overclock to 1.7 ghz while the screen is on, using the interactive gov. i also set up a "screen off" profile that is underclocked to 247? mhz so that while my phone sits in my pocket for the majority of the day or on my desk, etc, etc.... it conserves quite a bit of power.
ive been using this set up since i got my inspire on cm7 (whenever that had its first RC) and im getting anywhere from 48-60 hours of usage.
my daily usage includes: tethering, streaming audiogalaxy, ghosttown, pandora. camera stuffs, calls, texts, 2 email accounts syncing, twitter, facebook, calendar, palmary weather updates, and much more stuff. so im going to stick to this set up until someone says they can get more usage with all that going on.
I run min(250 IIRC) and max(1.5) using on-demand.
I was overclocked at 1800 but my phone would freeze sometimes to where i had to pull my battery. So I tried 1000 but 2 days and then 1500. I noticed little difference in battery us and speed. I stuck with 1500 but after reading this thread i am gonna try 750. I never used any battery monitoring widgets. Im gonna try that. I use Leedroid GB btw.
I'm running at 1.2ghz with Coredroid and am happy.
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.
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.

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?

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!

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.
