Just curious is most people who root/use custom ROMs overclock, and if so, what settings do you typically use in SetCPU?
I'm using a S2, rooted with latest Unnamed ROM and find myself contemplating if I should make any changes with SetCPU. Lots of options, and Unnamed has all the different governor options, etc. just really looking for some best practices that people who overclock often.
Would appreciate seeing what you consider to be stable overclock options that give a good boost without causing excessive heat/stability issues.
I'm coming at SetCPU with limited experience so I do appreciate any tips that might see rudimentary, or if there are better resources that teach about this I'd appreciate any links as would like to get a better technical understanding of all this. Thanks in advance.
I use No Frills CPU, and I just set it to 1.6 max/ondemand. Absolutely no heat issues or stability issues, so I just stuck with it. Battery life is good.
most maybe but only by a little bit. a good number of people underclock and undervolt their devices to try and get better battery life. to be honest, the newer phones dont need overclocking to handle the current apps and stuff. the older phones like the nexus one and older need overclocking tho. i leave my gs2 stock. what we really need is dual core support before OC becomes worth it on my phone. ymmv
I have never overclocked mine, phone runs smooth as butter at 1.2 so I don't see the need to go farther. Plus I like my battery lasting more than 24 hours...
I overclock my s2. im running unamed 1.3.0. I like run different speeds at different at different battery percents. 1.6 till 75% 1.4 till 50% 1.2 till 25% 1000 till 15% 800mhz till dead. i had some problems with 1.4 ghz but i tweeked the voltage and that did solved my problem. I'm at 50% battery with normal usage. display 1hr 25mn phone calls for 47min and android os for 56min. my phone doesn't get any hotter then it did before i overclocked. I just did it to say i did. It will prolly help a little unless you like emulators then it will help alot. i have to overclock my iconia a500 to 1.6 if i want to play n64 games.
I'm on UnNamed 1.3.1 with the latest entropy dd kernel and am very happy with the stock CPU speed

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.
What do you all say?

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.
I installed the webtop over hdmi mod on my Atrix and while testing it out, it got very warm in my hand. I opened the setcpu app and noticed that while overclocked to 1.3GHz, the CPU was running at 75C! I lowered it back down to the stock 1GHz and the temp slowly went down and settled at 63C.
It seems that while in webtop mode, the CPU is taxed at 100% all the time so I'm wondering if it's safe to stay overclocked when using webtop.
Everyone has different opinions of what is too hot around here.
IMO the cooler the better. IMI No Atrix should have a temp above 60c and I'm not even comfortable with above 50c either...

I have experienced the same problem and worried that something may fry.... I have had mine overclocked at 1.45 using debian linux and all of a suddent he phone freezes and restarts.... Since it did it to me the second time I have kept my phone at 1Ghz... I am new at this so please don't beat me up too bad for being a noob... Just want to see if maybe undervolting it a little might help or hurt it?
Thanks in advance
Here are some tips I can offer
1.Try re-flashing your custom kernel and see if that fixes the web-top thing and over heating
Whenever the phone is plugged to the web-top it will naturally overheat so it's kinda expected remember now it's gotta work harder since its displaying on lap-dock or TV,but if you can cook an egg on it it might be too hot...lol
2.Set profile for temperature on setcpu so this way once you reach for example 100F your phone will clock down a little and so it might help the heat issue.You can set even more than one temp profile so this way when it reaches 96 it goes down a little then when it reaches 100 it will clock down a little more and such.
3.If that doesn't help,which in my situation it did.Flash a different kernel mayb it's just the one you're using that is causing funny stuff to happen.
Edit: not sure but i think undervolting helps battery but causes more heat,I myself don't undervolt I just created litterally a bunch of setcpu profiles for battery level,screen off,incall,charging,temp,and time and I'm getting 13 hour days at 1.3Ghz and temp profiles have been helping by clocking down when it's too hot therefore saving battery and drastic overheating.I dontlike my phone going anything over 104F it gets me paranoid,but that's just me.
I tried reflashing the kernel but it didn't change anything. I'm using Faux's 1.3GHz overclock kernel for Gingerbread (2.6.32.9). Is there something else I should be using?

Do what sktrix said in rest of his post.
I use the stopgap 1.0GHz kernel, and UV does lower temperatures. I would definitely try UV'ing a wee bit. You don't need to go crazy. I am using the following with great results for both temp and battery life:
-50
-50
-75
-75
-75
-100
-100
My setcpu profile clocks it back if I reach 60C, (I idle in the low to mid 30's). Under heavy load I reach around 52C max which is quite acceptable.
Now, granted I am not using Webtop, but the end result for UV should be the same. Lower temps and better battery life. You may also want to try just using 1.0GHz when on Webtop. The phone has more than enough power at this clock speed.
There is a bug with faux's kernel that causes the webtop to clock the phone at max speeds until restart.

I know I'm straying from my correct forums here, however I have an LG Optimus 2X which like the Atrix, is a Tegra 2 CPU.
Our phones get VERY hot, I have had my CPU up to 86C before I decided to back off the stress test. CPUs are very good at handling high temperatures, and IMO you will see no ill effects from doing so, I am unsure of whether or not the Tegra 2 has thermal throttling/shut down, but in my experience they should be fine to around 80C.
The only issue I can forsee is the battery, batteries HATE high temperatures and it is awful for their life span, this is why your laptop batteries turn to crap after 1-2 years, even if low charge cycles, because they are always hot.
I would not be concerned about anything in the 70C realm, at all.

Experienced this countless times. More with the latest 1.45Ghz, but it did happen on the previous release. When I dopped the mhz with setcpu, it wont scale but stay at max cpu. It even did it a few times without using the webtop.

So which overclocked kernel is best for webtop? I too have noticed where the CPU hangs at 100% at 1.45Ghz for a while when disconnected but it is always there when im in webtop mode.... How is Faux 1.3Ghz kernel with webtop?

It will still hang at 1.3ghz, though it's a known bug. I just stick with the 1.0 enhanced, there's no noticeable real-world difference from going over 1.0ghz anyway, it's just a benchmark gimmick. Right now, the software that's out there is optimized to run on existing hardware w/o overclocks. I've run Shadowgun at 1.45ghz and didn't see any difference over the 1.0 enhanced.
Now, if we were trying to run games that were coded specifically or faster-paced chipsets then we'd need overclocking to catch up much like you would in the PC arena. That, however, is not happening in the cell phone market just yet.

Read the history at the following:

You will see a lot more optimization than just upping the clock speed. One of the reasons the 1.0GHz kernel works much better than the stock kernel. Also, the ability to undervolt saving battery life.
IMO there is no need for 1.3GHz or 1.45GHz in everyday use of a phone. The only benefit is for OC'ing bragging rights. Until we can control phone temperatures better, it's pointless to risk the substantial heat increase on ALL internal components for extended periods of time which results from much increased CPU temperatures.

I see... guess that explains why the phone doesn't really feel any faster when it's overclocked. I'll flash the 1GHz kernel then.
Thanks for the info.
Not sure if this is the same with phones but normally a CPU should stay at 40C idle and 50C load. Maximum would be 60C while benching or something.
If it goes above that I would definitely underclock/undervolt.

also has other fixes besides overclocking you can go read them in the kernel threads
Just wondering if anyone has done this with success. I have heard of speeds as high as 2GHz and was skeptical of this being safe. I figured it would cause some overheating issues. Also what is the best app for this? If this is done is there any noticeable differences in performance(most likely as this doubles the CPU power)? How much battery life lost? Is it worth it?
Thanks
Seriously, use the search or take a peek in the dev section. 1.6 GHz is no problem at the moment. Oh, and for me, it is worth it.
Check out vipercontrol mod in dev. Section. Allows overclock to either 1.5 or 1.6ghz. PRIME CAN EASILY HANDLE this as it was tested by Asus themselves on those speeds. It was seen in the source at first but we couldn't use it. NOW Viperboy made it possible to use those higher speeds. Its more of a mild to normal overclock. Its very easy to do. You will need to install vipercontrol mod to your prime and also terminal emulator. INSTRUCTIONS are in that thread.
WE have even found another method to run parallel to vipercontrol mod to allow overclocking of all 4 cores to 1.6Ghz. Vipercontrol, St the moment, doesn't do that by itself. JUST ALLOWS normal overclocking as Asus had it.
Seems kind of odd that ASUS backed off on the performance by 30% don't you think? Maybe they just wanted to do more testing, or maybe it was a last minute change based on their first prototypes.
Mine seems OK at 1.6, but I don't feel the need to overclock it in general use - unlike my phone which I think will have a shorter life as a device anyway.

I think it was more about more money down the road. AS I'm sure you've heard of Lenovo tablet coming out months down the road. Its gonna use exact same tegra3 chip except with the 1.6ghz enabled on it.
THINK of it this way, why would Asus/Nvidia release its first quad core device already at 1.6ghz? Its already the most powerful tablet at its current state. They did this so down the line when newer tablets come out, it'll be more incentive to like the device or think it's more powerful if its clocked higher. If prime came out with 1.6ghz enabled already, then how would that look to consumers who buy tablets months later that have exact same speeds. PRIME would be the better value and those newer tablets wouldn't be all that appealing, As far as power goes. SO the newer manufacturers can have something to boast about. Like hey look at our device its clocked higher therefore more powerful. Another reason also they didn't enable it on the Prime was for battery life. At its current state, stock, prime gets excellent battery life no matter what mode you in really. HAVING 1.6ghz enabled, as I do now, drains the battery at least at the same rate as performance mode or more. PLusbif you add the extra boost to vipercontrol overclock using system tuner, then battery really drains alot faster. Because then I have all 4 cores running Max 1.6ghz at the same time. Viper control doesn't go that extreme, yet.
YOU ALSO have to remember Asus and Nvidia designed the Prime together. SO prime n tegra3 speeds are really a testing ground for future setups in future tablets. That's how we were already able to see the higher speeds a couple updates back but couldn't use them till vioerboy made it possible or you figured out how to do it with root and going into /system/etc and executing the cpu5.sh script.
I LOVE the overclock but find myself now going to stock speeds to see how they compare. STOCK speeds are really good, especially with ICS. EVERYthing is smooth n superfast.. Overclocking does make it even faster but the tradeoff is slightly faster battery drain. PLUS there's nothing out now that stock prime really can't handle. SO no real use for needing to overclock, yet. UNLESS you just want your device to be the fastest it can be. I keep switching now. Lol. Ill have it on stock speeds n as soon as I see a mention of overclock. It compels me to do it. N vs. Versa. ACTUALLY. Even with vioerboy overclock, battery life is still good. Just not as good as it would be on stock configuration. Now once bootloader unlocked, we will see overclocking paired with undervolting. So we can get Max speed and Max battery life. Or at least get the overclock to get same battery life or better as stock configuration. DONT be surprised if you see us hitting 2Ghz overclock soon. Its coming. Then if paired with system tuner, we could have all 4 cores running @ 2Ghz a piece all at the same time. unbelievable!
Hello! i am in the process of overclocking my thunderbolt in order to get better performance with the eternity rom, and i was wondering what you guys oc your phones to? and if you do, what program/setting do you use to do so? (i plan to use a script in init after have found suitable settings)
I, personally, find it pointless to OC the Thunderbolt. The phone is fast and smooth enough for me on the stock speed, plus the battery life is bad enough without adding more strain to it.
However, if you insist on OC'ing, 1.2GHz is a safe bet. Some people can get to 1.4GHz, but then you run into freezing and random reboots. Also remember that individual phones handle overclocking differently. Where one phone can run perfect at 1.4GHz, another might freeze instantly when going that high.
Good OC'ing programs include SetCPU, No Frills CPU, and ROM Toolbox.
I don't overclock. That being said i have OC'd my phone b4 i have had it up to 1.8 Ghz stable, but it doesnt seem to make anything run faster. I use the Thundershed version of CM7 and its super fast. I dont think it could get much faster. and without overclocking i get better battery life.
thanks for the info actually ended up going with the lean kernel which is oc'd on the kernel level, works fairly well

pros- increased speed and less lagging,
cons- short battery time, increased temprature.
Is it possible to underclock it to get more battery or shelf life from the phone?
we can overclock and underclock if we install custom karnel..

Overclock will give you temporary boosts and lets you to showoff, and to get super high benchmark scores , but its not for regular use
Overclocking reduces battery performance and increases heating of device, which might cause your device to get unstable
and of course high temp = bad for the hardware so be careful
My SE mini works very well at 1610 Mhz.No crash,no instability but I use high frequency for max 2-3 hours or when I want to play without lagging
Pros
Immensely fast speed
Massive score on Quadrant
No lag or crashes
Cons
Battery life goes down fast
Phone temp goes up - Massive problem
Phone might get bricked if the phone gets unstable (Happened to my friend)
I only overclock my phone whenever I play games or need to switch between apps constantly. Though I always keep on 1024 as that is the default setting
Recently I overclocked to 2ghz was chkin stability and gosh I burned my battery, its workin but fone keeps restarting n I had to buy new one!! Dis is d con
Pro: faster n better performance!!
Overclock can cuz serious damage too!! But its fine to showoff a lil but in controlled envionment for a short tym!

Overclocking is not actually advisable because there are chances that it will affect your phone and might screw it up in the long run .
Battery drain is inevitable and you will experience it .
Phone will heat up
It may not be good for the other internal components because of the over heat-unlike computers a mobile is not actually equipped with much of cooling system.
There is a good reason why the manufacturer has set a clock speed ,otherwise isn't it better for them to just overclock a phone and sell it for a higher price ?
People who design the custom kernels are just telling the maximum possible value they could overclock to.
Pros-
Bigger numbers
Little more faster performance
it recommended to not overclock always..just overclock when you really need it..
What are peoples thoughts on a modest overclock to bring me back up to the performance I am used to?
Say taking an ACTIVE up to 1300 or so.
With these new NON-OC kernels, are they undervolted? I have seen claims of absolutely massive battery life and I'm reasonably sure some of those were using cpu throttling and an overclock.
So confused at this point. Also heard some of the newer ACTIVE handsets cannot even be rooted.

As in most things if you not overdo it you can enjoy the benefits of better performance without risking your phone.My xperia mini is running up to 1200 (1024 stock). Also minimum speed 122 instead of 245.So better performance when you need it and lower consumption when phone is sleeping.Overall i got the same battery life, 2-3 days as with stock rom.The best thing to do is get an app that lets you make profiles.Like when screen is off min cpu 122 - max cpu 384 etc...
I don't know about these new kernels you're talking about but cpu throttling is something stock kernels do also (if by cpu throttling you mean cpu speed adjustment)
