It will definitely shorten the life of the battery. As for the phone itself I can't really say. I used to use my vibrant @ 1200mhz daily while running bionix 1.3.1. I never really noticed any wear and tear from the overclocking. If your phone runs warm while overclocking you should really consider running the stock voltages. Your phone may overheat and fry your cpu gpu with the high temperatures. So be careful when overclocking.
Meh i dont completely agree...
It will only shorter the life of your battery because the processor will draw about 20% more power which is very small compared to the like 20x more power the lcd takes up.. i dont think youll feel the difference.
The heating up i disagree with too since ive seen processors reach boiling point of water and continue to work.. thats not to say they all will but ive oced my phone to 1.6ghz to benchmark for several minutes and it never got above 41*... the battery heats up alot more when its charging than the processor does most of the time so i wouldnt worry tooo much about that.
Now as to whether the phones llife will lower... yes probably.. youre putting more stress on the processor than if you dont oc.. honestly tho, processors dont die very often so i oc all day as my daily runner, usually to 1.4ghz if my kernel will do it..
Up to you and honestly all of this is my opinion based on my available info etc.. hope this helps

Everything I have read says 1200 is completely safe. I run mine at 1460 with no issues. It obviously draws more battery but using Voltage control app you can adjust the level of battery.

You would be fine with 1.2Ghz, but look into a kernel that supports some slick CPU scalers (smartass is a good, easy choice). You can set that (1.2Ghz) as a max clock and you can let the scaler determine how it gets there (if need be). Running only 2 clocks (OC and deep sleep) seems a bit overkill to me, but to each their own.
Like everyone else said, you ought to be perfectly fine with that value.
The highest I would go is 1500 though

Lol, running an overclock on a phone seems a bit overkill to me...
Think about this.. How much copper is strapped up to your phones cpu?
Would you overclock your desktop on a stock cooler?
I feel sorry for the saps who buy phones second hand(especially after reading this thread). (hey wait a minute, that's me too.. Lol)
I never overclock anything.
Ever.

With Linpack I see people getting to 848mhz and even 1ghz.
I lose stability at 787mhz and I'm ok at 768. I know that different chips vary... but 1ghz difference?
Is there a way to overvolt on the Eris I don't know of?
The eris OC at 1ghz....thats a lie and some one is pulling your leg lol. The eris is not built handle that and if it did reach 1ghz the motherboard would burn up.
Yeah but 848mhz isn't so farfetched. I can do 787 for a while without any freezes. The freezes do happen though.
If you overvolt it shouldn't be impossible to get up to 848mhz.
As for the 1ghz + entries on linpack's site I think it must be another phone running Eris ROM's/ basebands.

I can do 806 all day with Aloysius but my buddy with the same exact setup (i setup it up, so I nkow its exactly the same) can only get stable at 768.
I have not seen anyone with proof or that is respectable, show that they can keep their phone over 806.
"Begin envy now "
I do lol
So there are NO overvolt kernels/ methods?
I can run 806 stable with evil Eris 3, most of the other roms crash when I clock them at 806.
Lucky lol my processor seems to be stuck at 768. 787 doesn't last too long and it's not worth the random FC'ing. I'm sure it would be stable with more voltage and heat hasn't been an issue for me at all at 768 even with Pandora/ Zenonia running for quite a while I haven't gotten even lose 50C.
The question is why would one want to OC that high. I see absolutely no difference in performance at 710 vs anything higher. Probably even lower than that. I just don't see why you would want to run any higher and eat up your battery as well as tax the processor and board more when there isnt a noticeable difference other than linpack scores. Just my opinion but I think all new to OC'ing should be aware that faster isnt always better.
I know that lol I mean... a lot of people who overclock computers don't do it for a performance boost, they do it because they want to see if they can. They won't get better gaming performance they just get a slightly better benchmark.
I want to do it just to do it.
Ok rock on speed demon On that note, I wonder if it could be clocked to the max in a freezer room. If the low temp would help or if it is just hardware limited.
The MAIN problem with overclocking with voltage modification would be heat/ ****ty PSU. I'm sure the Eris battery can get up pretty high, it's a matter of staying cool. I would like to see how high I can get with cooling but I don't even know if overvolting exists for the Eris lol
Dont know about over but I know you can undervolt on it.
If there's undervolting there should be overvolting... someone has to know lol I've tried searching XDA and google but I can't find anything specific.

I tested 710, 768 and 806. I didnt just test with linpack either. I just used apps I normally would run, running for a few days and what not and noticed a difference from 710 to 768 but not really a noticeable diff from 768 to 806. I still keep it at 806 for reasons that my battery life is better. Dont ask me how or why but it just is. I have mine set at 806/480 and for sleep, 480/240. Now most of the day my phone is just in my desk drawer so that could be the reason but i still go a full day with heavy use at the end of the day (bt, wifi, internet radio, run keeper) and still have about 30%+ left when I go to sleep at 10
I have never had a problem with battery lol since overclocking my phone I've only increased battery life. Significantly so.
There has got to be some sweet spot there for OC'ing that gives best perform with least batt consumption. Just wish I knew what it was.
People are getting high because all processors aren't the same. So some can handle, some can't. As for the 1ghz it's a big lie. According to several people including jcase linpack scores can be easily edited and faked. I wouldn't believe anything on linpack that's outrageous.
I sorta figured they wre faking somehow. And I know some processors can handle higher speeds, that's the basis of overclocking. I want to know if I can overvolt my processor.
Can't help you there. Maybe go ask in the IRC? I'm curious if you can as well.
I can hit 787 and run stable... linkpack scores around 5.3-5.4. Oddly enough, my fone refuses to run at 768. I actually have to use a txt file for setcpu to remove 768 from the equation with profiles and the setcpu "trick" my battery life is GREAT. Much better than "stock" even.

Excessive overclocking really did damage your hardware, depends on the quality.. Overclocking from 1.0ghz to 1.5ghz really give a performance boost, in benchmarking.. In real life, only noticeable in process hungry apps, such as 3d games.. Gimmick? Well, if its a gimmick, it won't give any sudden resets or lock ups.. The processor have a safety switch if the temperature increase because of oc'ing.. If it's to hardcore, for example, 1.0Ghz to 1.8Ghz or even 2.0Ghz, for sure you processor will overheat and lock ups.
Well, mine running at 1.5Ghz, no lock ups or whatever..

You will barely notice the difference in most circumstances. Even if your phone runs fine at 1.5 or 1.8 ghz it will probably reduce the life of the chip over a prolonged period.

it will help in cpu intensive tasks, that which require lots of calculations, math stuff, 3d drawing done via cpu, faster cpu, better...
in other tasks, don't even bother, there are lots of other things far slower then cpu.
downside, heating, battery drain, increased rate of damage..!
Im using SetCPU for saving battery life. Set the cpu for 384 while screen is off. Noticed quite a difference.
OP, your asking if a overclocked cpu will give a better performance or if it's a gimmick? Really??
Of course it will give you better performance, that goes without saying but the question is, are you willing to sacrifice battery life? The chip will most probably last for years and years if overclocked but 1 thing that kills chips is heat and volts.
I only overclock when I need to and when I'm done I go back to how it was, usually.
My phone is fast enough at 1GHz, dont need overclocking, all games and apps goes fine fine
Most OC kernals are also undervolted anyway so I wouldn't worry about it
to be honest, i use mine with "underclocked" at 800mhz, trying to get at least a half-hour of battery life... i don't see the point in overclock a 1ghz processor, imo, even with a speed gain, the bad side effects easily override the good ones...

I'd look at other reasons for your battery life, if it's really that bad.
I'm running at just a touch above 1GHz with no side affects what so ever and get 24+hrs with heavy use, 30+hrs with moderate use and 40+hrs with light use, and that's never turning wifi / 3G off unless I'm in bed when I switch to 2G.
At 1GHz the OCUV kernal I have installed uses less voltage than stock kernal at stock speeds so in theory it's actually safer.
It's not that bad, but it's not so great as yours too. I got about 16hrs with 'hard' use, what is enought most time, but sometimes i get in home with the blinking orange led. Quite annoying...
I try my best to improve the battery life, but i was becoming a battery freak, or something like that, always checking currentwidget...
I get 3 or 4ma at stand by, what is considered normal, i guess... and always use full brightness, hate to use anything bellow...

Full brightness is your problem. I bet it uses like 70% of the current while you use your phone.

First off, I would like to apologize in advance in case a thread like this exist and I can't find it.. :/ (Search is down, tried Googling) also, if anyone believes this to be in the wrong forum.
ANYWAYS! This is intended to be a preference/opinions thread centering around your OC/UC and Undervolt settings. Feel free to post your current set-up in Voltage Control (or any app of the like) and what Kernel you are running! I wanted to start this to get an idea of what everyone else is setting their UV and CPU clocks to, and possibly give a few of them a try on my own device. :]
Personally all of my clock speeds are at their defaults except for 1000Mhz @ 1200mV. (-75mV). I am also rocking Genocide v1.0 and getting a decent 30hrs of battery life with pretty moderate use.
Post away!
It is kind of pointless since every phone is different so cannot do exactly the same as others. Most can't do 1.4Ghz and most don't wake from sleep at 100 Mhz. All depends what you use your phone for. Mine runs fine at 1.3Ghz except for some TV apps will freeze.

I believe that would be my point however.. curious as to what other people are running as far as cpu and voltage is concerned. Their success and failures. What people can get away with and remain stable. I, and others, could then try their setup (taking precautions of course; ie Nandroid backup.) And see what we get. Who knows, maybe I might adapt a set up that runs better on my device than my current one.

Yes, every phone is different, but that is just more of a reason to collect data - perhaps a baseline can be established, which would be helpful in determining if a particular phone is messed up or just at the low end of the scale. Right now it is hard to determine if a particular phone's troubles are caused by low quality or by damaged hardware.
I keep all voltages at stock, and don't use any OC - my phone runs fine as is, and the battery life actually seemed worse with UV (and my screen felt hot with the screen UV).

My phone wakes from 100 but won't do 1.4ghz for even a couple seconds before reboot but 1.3ghz lasts about 20 minutes before reboot and 1.2ghz is stable. As for undervolts it can handle -25 on 1.2ghz and -50 on 1 and 1.1ghz -50 on 800mhz and that's it otherwise becomes unstable and reboots. Battery life and performance seem to meet at 800mhz with a -50 undervolt games run smooth too and 12 hours of battery. Oddly enough benchmarks are consistantly higher on 1.12ghz than on 1.2ghz I wonder if I'm the only one?

Just to throw it out there. Aggressive undervolts will do more harm than good to your battery life. By that, I mean you'll drain your battery even more.

I can only use Genocide kernel to get 1.3ghz at stock voltage with since all the other choices are uv'd. My last two Epics were able to handle uv'd 1.4ghz by 50mV but I'm not really complaining as I think this is a new phone they gave me and not a refurb. I currently have 100-400 uv'd by 100mV, 600-1000 uv'd by 75mV and 1300 at stock.
My phone can handle 1.4 Ghz but only with the stock voltages. If I try to touch it even by 25mV it locks up.
Who all has enabled the 100Mhz step? I noticed when I did my phone went into Deep Sleep a lot less by a noticeable amount. Staying at 100Mhz a lot.
Always interesting to hear about all this theory behind the reasons for undervolting OC and UC, then to hear about the issues (at times extreme) some have. I would also like to know who uses the 100 step and if it is noticeably better on battery life than the 200? Unfortunately I am missing out on it if I am. Still running Genocide here, but with 1.0 at -50mv 800 @ -50 and 600 @ -25. Very stable and still at 30+ battery life. Having 1.0 down 75 made me nervous. although I hear people dropping it down -100mv successfully.

Good tip about "aggressive UnderVolting"...didn't know that actually drains your battery more. Might explain why 6 hours into my day, my battery is down to 30% already!!! I had it set at 1120Mhz UV to 1175mV (Stock = 1300)...
So now I'm going to try 1200Mhz only UV by 50...see what my battery life is after this!

Can you explain how this is so? Is this based on any actual research, experimentation, or online documentation, or is this just your own opinion?
Unless your undervolt causes the CPU to hang (I've seen mine start to warm up when it's hung, until a battery pull), I don't understand how providing less voltage to the cpu will cause it to drain the battery faster.
If you change the voltage settings please don't blame the rom developers when you phone bricks...

In most [low-end] phones little OC consumes a lot of power, but I don't see this issue in SGS.
Are you using your phone overclocked? How long last your battery?

there can be a difference in battery life, but there does not necessarily have to be one I assume... after all, it is only the maximum available for the processor, most of te time it will not run at that speed... I for one do not overclock my phone (actually, I have underclocked it to 800mhz) since I have no need for these speeds (just using my phone for messaging and some browsing)...
please correct me if I am wrong since I do not know much about how the SGS processor exactly works
i cant see how it shouldnt impact battery.
As we can see in many forums, people like to overclock their phone to increase It's performance although overclock can increase battery live and may broke their phone. I think the increased performance can only be felt through benchmark software. The effect on the apps is almost negligible specially on high end phone (like our Note). Why do you overclock your phone and use overclock on daily usage (I understand if the reason of overclocking phone is for satisfaction) ?
Never saw the slightest reason to overclock my phone.
Emulators and because I cannot resist getting extra performance. My captivate was a beast OCed.
Some people don't get it others do...like everything in life. Some don't get how we can live with a phone this big but we do...

On GB (LC2) I overclocked to 1.6gHz and it made everything run smoother (screen transitions, opening and closing apps etc.
On ICS I haven't felt the need to OC. It runs super smooth and fast as it is.
But maybe I'll get bored some time in the future and do it just for something to do...
I'm on stock GB LC1 CF rooted and I OC to 1.55.
Differences when I open apps. They open faster. And not that huge battery life drain because cpu stays at 1.55 a little time and for me the faster app opening matters

Its not bout whether its "important" or not... Its more like, If you can...then why not!? I did overclock my sgnote till 1.6ghz at 1.7 it would reboot.
Its like gettin more for less
Just as Overclock with your desktop, some take a step further by changing heatsink, better ventilation, water cooling, etc.
Exactly, its just free power and if you are not dumb, you are not going to kill anything. This is not the dark ages of overclocking and those fears people seem to still carry from those times.
Take for example on GB running 1.6Ghz Nenamark2 scores me about 34fps or so..Damn close to my record with the Captivate which is 33.5! Then I ran 400Mhz on the GPU and boom..53fps...that is some kick ass gains there. While I will probably run 300Mhz mostly, if I find a game that needs the extra performance, I know I have it there so why not use it.

Very true.
On my desktop I have an Intel i5 2500k (original 3300 MHz) OC to 4500 for daily use and when needed 5 GHz.
From 1 year and a half the CPU runs like this and never had any stability issue. And my PC kinda stays on A LOT.
So yes, we don't live in the dark ages of overclocking. Why people STILL HAVE FEAR OF OC!?
These days OC is very easy. Most of the times you can't broke a device / component from OC, because the "drivers" of some microcontrollers from your motherboard won't let you (a lot of protection these days )
Indeed. Plus if you are too afraid then dont push higher voltage, just OC with stock voltage as much as your CPU can do.
