OP - ^^ this. Good advice. Start with stock voltages & gradually decrease until you get to the lowest possible whilst remaining stable. As Rocky has said, there's no shortcuts (apart from the the posts on this subject on here), it's trial & error.
And the other thing, don't expect to see massive increases in battery life with undervolting. Yes, you'll get some increase over the life of a whole charge, but it won't double your battery life or anything like that. So far as the heat issue is concerned, of course your phone is going to get hot if you overclock.
The phone is only made to go to 1200mhz out of the box. If you want to overclock, heat is something you're going to have to learn to live with; tho undervolting might reduce the heat produced by overclocking a little bit.
Overclocking is the same as undervolting in that some CPU's can handle more or less than others. Your phone might be able to handle 1600mhz just fine whereas the CPU in mine might only be able to handle 1400mhz. Same with undervolting, stable values for me might cause your phone to crash.
adding to the above you could also check this thread:

Its an EXCELLENT thread to start with as there is quite some information as well as sample values for you to play with. Keep in mind that those values might not work with you but you can experiment a bit in order to find the values most suited to your phone.
Also i think you should take a look in this thread

Alright, then I'm sorry Google couldn't answer your question. (Which is odd, since overclocking is kinda popular.)
Anyways, Overclocking means to "Make the CPU go faster than it was designed for". Some devices "like the hero" can jump from 518mhz to a stable 691mhz by overclocking, this increases the speed of the CPU so that programs and the OS can work faster.
But overclocking is about finding the highest speed, while having the stability to use it. Since it's no use to overclock, if it makes your phone unusable to use. (Force closes, phone freezing etc.)
Overclocking CAN harm your device, if you take a too high value. But if you stay inside a stable zone, there shouldn't be any harm to your device.
You can experience that the phone is getting a bit hot, or that the battery is emptied faster than normal.
Since the CPU drains so much power, there are settings that allow to set a different clock (how fast the device should go in mhz) when the phone is at sleep. So that it can run at a much lower frequency, when you don't use it.
ROM developers normally post ( 691/197 ) or something at their thread, the first number is the CPU speed when it's on and you're using it. And the other is when the phone is at sleep.
If there's anything other you want the answer to, ask it here.
But, please use Gooogle search Before posting anything.
Overclocking increases the clock speeds of a CPU. And as a result means it can do *things* faster.
Overclocking on a desktop PC tends to increase the voltages to overclock the device over this isn't really an option on a phone as it has limited battery life. So overclocking on a phone is normally done by software changes. When CPU makers make a CPU they can not be 100% accurate on the performance of that chip - in fact its very much the opposite, so after each chip is made it is tested and then given a clock speed and locked to that, overclocking breaks that and allows you to manually increase the clock, however overclocking capabilities will be different on every device.
If you take an example of an Intel Chip, a 2.66GHz Core-2-Duo, this is exactly the same chip as the 3.06GHz however when tested it wouldn't run as fast so Intel sell it at a stable clock speed.
Overclocking the hero shouldn't really have any implications for the device, however overclocks can reduce the life-time of a CPU (and any other hardware you might overclock). You shouldn't notice much extra heat from the device as the voltages being used are not changing.
Hope that cleared some of it up for you.

Hey all,
I come from an extensive background in OC'ing my own systems, pushing them to the extreme for noticeable performance increases. The one thing I know though, is that it does add wear and tear on the components, and shortens their lifespan. Is overclocking the Vibrant really worth it? I'm not sure if, with a ROM like Axura 2.2.5.7 which is blazing fast already, an extra 100 or 200 mHz is really worth the risk/performance.

the only reason i OC is basically just so i can tell myself that i am OCing. If that makes ANY sense. its basically just my phone OCD.
to answer your question, even though you kind of already answered it yourself: the only reason you would actually NEED to OC is if you game a lot on your phone, if you do a lot of multitasking, or if you have a lot of data transfering going on (which i do). other than that, our processor is pretty powerful, and can handle 95% of what is thrown at it.
With that said, since youve indicated that you are satisifed with your phones performance, i would say the only thing you should definately do is install a lagfix (if you havnt already). if you dont need to OC, do your battery/hardware a favor, and dont.....unless you have phone OCD like myself.
PS - not to ramble on, but there was actually a 2-day period where i actually wasnt OCed and i didnt know it (i guess my app reset itself or something). i remember saying to myself during that time that my phone phone seemed a little laggy and much slower than usual....then once i discovered that my OC wasnt applied, it made sense. but keep in mind, i have my phone doing a lotttttt of things constantly, so OCing may not have the effect on lighter users that it does on myself. pretty crazy what a .2 ghz difference makes
Like above stated, OC is only needed if you do some intensive task on your phone. In addition, most of the Overclocking Kernels are targeted at a broad audience, what I meant by that is the developer bumps up the voltage enough so that only a small amount of people experience crashes. However, user generally have no control over the voltage themselves and any increase in voltage is bad for electronic components. (exception being some of Eugene's kernels which allows UV by user).
I don't, its not needed. I like my battery life.

I dont usually oc unless I am near a power source. last night i tried the Dow kernals and wow my phone was dead within ours even while in standby. Imo thats just nuts. Even while Oc'd it shouldnt die that way.
What I am looking for is a kernal thats compatible with nero v3 that will maintain battery life aslong as I dont oc.
I have seen this post http://eb-productions.proboards.com/index.cgi?board=samsungsgs&action=display&thread=28&page=1 on Eugenes forum but non of the info makes sense. The one that does make sense has a older modem than the one I am using.
I guess I am use to the hd2 in which I would underclock to maintain decent battery life and use profiles. It doesnt seem like this cpu likes the profiles. amirite?
I would OC no question if we could get a UV kernel with good battery life like we did with Eclair. I won't do it with Froyo because of the terrible battery on i9000 kernels.

What TopShelf10 said is correct. Basically the trade off is this.... faster kernel.......quicker battery drain. That is the trade off. I have used oc kernels ...I do not use the phone for games, so EVERY thing I do on the phone the oc is not necessary. That statement is true for 95% of us.
BUT, that said, there is some cool macho feeling you get when your phone is in overdrive, just like my car, 350 hp but I live on an island that only allows 25mph speed limit...still, it doesn't change that feeling of awesomeness I get when I start the engine
I had nothing but issues with each and every OC ROM I tried. App alarm, pandora, slacker, ect. It was always something. My phone would actually get random freezes so it made the phone feel slower. Voodoo or OCLF on the other hand work wonders.
is it worth it?
well, here were the trades i had with dow14:
going from 13-14mflops to 18-19mflops in linpack (yeah, it's a benchmark, but it's hard to otherwise convey how the oc directly translated to the phone being extremely fast otherwise).
battery life went from easily going 22+ hours between charges to going 6-8 hours between charges.
however, with the core 1.2 oc i had great battery life and performance. so i assume (and have gathered from reading people more knowledgeable than me) the battery downside is due to it being a i9000 kernel. so hopefully/eventually we will get source for the vibrant 2.2 kernel and get an oc kernel with similar performance but much better battery life.
and until i flashed nero v3 and using voodoo, i kept super io and dow14 kernels on my phone so i could flash the oc if i wanted the performance or flash super io for battery life/day to day.

Opinions from people who really know? I can't imagine that overclocking increases battery life.
It doesn't. At least from my understanding. In fact as I understand it running at higher clock speeds would decrease your battery life no? I usually under clock, so...

The theory is that overclocking allows you to complete processes quicker, which in turn allows the processor to go back to a idle/deep sleep faster. In practice it doesn't really work that way though.

doesn't the increase in voltage also come into effect?
They did talk a little about undervolting to increase battery life. Personally I don't worry about it. I'm not using my phone to sort out heavy algorithims at the moment, so running how it does is fast enough for what I use it at. Just found the article interesting.

They say the undervolting on lower clocks should balance out the higher voltage on overclocks.

Undervolting rarely makes a difference on mobile SoC's, but on the desktop/laptop CPUs you can really save a ton of power with undervolting and underclocking.
Why to overclock and understand it?
Here is a good reason to know what you are doing..
and the battery avg's lasting at least through the day, but most of the time, I have a charger near me...

The article says its not the actual overclocking that is saving battery life. When you put SetCPU on your phone not only can you overlock but you can underclock and set different voltages. I'm not 100% sure how the voltages play into it but you can set the processor to run at really low speeds during certain acts ei. when the screen is off, or any other time you don't necessarily need alot of power. That's and I changed all the voltages (I got them from a post where the guy knew what he was doing and tested them). I get almost 2 days moderate browsing, apps and text. If I talk alot or use my hotspot I only get 1.5 days. It is a little time consuming to get everything just right but when you do you really see it.

This isn't a SetCpu feature there are other programs that can do this as well. It just so happens SetCpu has it built into the program. I bought SetCpu back in my Atrix days and loved it so it does work great for a simple tuning program.

I'm running a kernerl and a custom ROM that allows me to underclock and overclock.
I tried it out both ways and the battery lasted for almost the same amount as on the stock option. As I tend to play games a lot on my phone, the underclocking ran into some issues with stuttering and sometimes force close of a couple of games.
Personally, I've never been a big fan of either .
Disclaimer: I realize overclocking and tweaking is very much device specific and what works for one person won't necessarily work for another. That said, I've done a fair amount of reading on the subject but need some clarification on the finer points, along with some opinions on what's working for other people. Most of my questions pertain to the Devil kernel, as most of the settings aren't very well explained. I'm running AOKP M6 with Devil kernel and I've set a modest overclock with 200 minimum and 1200 max, which seems to be pretty smooth and stable. I haven't really felt the need to push it yet
1) What governor do you prefer? From what I read in this thread, SmartassV2 sounds the best and so far it seems to be working okay for me. Also, do the profiles matter (smooth, normal, powersave)?
2) Is it wise to mess with the memory settings in the Devil kernel (zRAM, etc) or should I just leave it alone? What about swap files? Worth the hassle or not?
3) What's the difference between using Live OC and the ROM settings to OC? I've left Live OC alone, and just used the AOKP overclocker to set my values.
4) I know that I've read Deep Idle doesn't work for our phones, but what's the Devil idle setting do?
5) Right now the Screen Off- Min/Max Freq setting is off, but should I set the values for that or does the SmartassV2 governor automatically handle it?
6) Any thoughts on I/O Schedulers? From what I was reading, SIO seems to be the best choice, but then again it seems to be all a matter of opinion.
Thanks for any input you might have on the subject
Alright well I think I'm getting a better handle on this since I've had a few days to mess around, and I'll post some of my thoughts in hopes it might help someone else who's trying to mess with OCing. Problem is that AOKP ICS is already so buttery smooth that overclocking really isn't that noticeable of a gain (at least for me).
As far as clock speeds I've been sticking with 200MHz min 1.2GHz max but might just drop back down to 1.0GHz to save some battery life (I don't really run cpu intense apps that often so I don't really see a huge need). I'm not really going to mess with Live OC now that I understand that it overclocks the bus too... I've screwed around enough with PC overclocking to know that it's going to seriously compromise stability which is a risk I'm not willing to take right now (not to mention it'll probably drain the battery a lot more than 'standard' OCing). I've also found that screen off 400MHz min and 800MHz max works well for me, because although 200MHz min will work too, it lags far too much coming back from standby for my liking.
2 things I still haven't messed with are the RAM settings and devil idle (which I assume doesn't work anyway). As far as the RAM I've never once ran into a low memory issue so I don't really think it's worth the trouble (due to reading this forum post I found).
I changed to SIO for the I/O scheduler but really can't notice any difference from just the default, but I'll keep it set there for good measure I guess.
Well that's it for now, if I notice anything else that might be helpful I'll post again, and if anyone wants to jump in with their experience or settings feel free.
Thanks

I have run PBJ, Saber, Perseus and Beans Stock so far (all on Beans ROM). I only messed with overclocking and undervolting on perseus and frankly didn't notice any real difference. For me Beans Stock has been the best for battery life (just cracked 2 days on a charge with 3 hours of screen time), but even that is only slightly better then I got with the other kernels. As for performance the phone is so good I can't honestly say one is better than any of the others. I am sure some people can post some test scores that show one being better than the other, but I am not sure in the real world there are major differences.
Alright thanks
I like my kernel Really, stock is already pretty good. For what 95% of users need, it will do just fine. My kernel just strips out a lot of stuff from stock and leaves you with pretty much just what is needed for the kernel to run, not much more. Overclocking isn't going to do much for you outside of getting pretty benchmark numbers. Undervolting also isn't going to do much for battery life as you won't be able to drop the voltages enough to do anything appreciable. Having 50 different I/O schedulers and CPU Governors is great on paper, but really, most of them aren't going to improve performance or help battery life.

For what it's worth, PBJ was a close second on my device to Beans Stock. I would rank them 1 and 1a. I totally agree on the OC and UV comments...I tinkered with them a lot and it didn't seem to do anything. Appreciate your work...I was a Tweaked devotee on the droid charge.
Something that people probably don't realize, overclocking and undervolting will negatively affect the power usage stats in Settings. They are based on specific power usage levels for each frequency, and if you add frequencies or change voltages from stock, the stats won't work correctly. Will it be a big difference? No, but it will be affected nonetheless. It wouldn't make the battery drain faster or slower, but it would affect what application(s) the system sees as using the most battery.
Alright so if I use your kernel it won't miss up MeanBean stuff?? Are should I just leave it stock

Subjective questions and what they do for you:
As a member of many different forums and networks, I see people asking subjective questions all the time and wanted to expand on them and what they do for the person asking.
I am going to use the topic of smartphones for the purpose of this post as it's easily the most frequent.
People always ask what launcher they should use, or what app works best for something etc..
Typically my answer [albeit cold and withdrawn] would be something like, "try all of them and choose the one that works best for you". This response is usually met with hurt feelings or some troll itching to lash out and pull his keyboard commando card.
I will liken this scenario to a car or truck. If someone were to ask me or you what make and model of car you drive and what you like, you could easily answer Kia [I'm using what I drive as an example here]. Then typically they would say they heard Chevy was better or Ford has something similar blah blah blah.
Ok, then if Chevy makes something better then why the hell did you ask me?! This type of question is always subjective because it builds on my personal choice. My preference. But the person asking the question almost always has their own preference or bias which taints the question to begin with.
Any question that asks a person or group of people for an answer that is inherently based off of personal preference begs to be answered the same way. It also makes the person who asked the question look stupid because they were too lazy to simply try the options and make a calculated decision themselves. They don't have the capacity to form an answer of their own. This is the uneducated method.
So when someone asks me which launcher I choose, I could answer Apex Pro. But that's only because it works well for my needs and my application which is specific to me and me only. Hundreds or thousands of people will argue why Nova, Launcher Pro, Chameleon or one of the many other launchers is better. This is an endless argument as again, the best launcher is the one that works best for you. On your phone. With the apps you have installed. The way you use your phone. The same holds true for kernels. Case closed.
Subjective questions will almost always be met with subjective answers. The easy way to not make yourself look and come off as lazy or stupid is to try things yourself and decide which works best for you in your specific situation.
