TEAM n0ob FIRST RELEASE!
Ok after my OverClock How-To, I decided to play with overclocking and see what exactly can be gained from stock Max regulator Voltage (1.3v). I have found that at stock you can get up to around 1.13ghz. It is slightly faster than what pershoots kernel runs (38400khz).
As persiansown says, the standard stock voltage is set to 1275, and the regulator is maxed at 1.3v.
What Kind of gains will you see?
You will notice a difference in games like Asphalt, that use a lot processor. You will notice a decrease in battery life as well. Your linpack scores will vary from about 8.5-9.5 depending on your chip.
I have included pershoots undervolting, 21MB ramhack, and audio hack as well. Several optimizations, following in the footsteps of the Ivan/intersectRaven Kernels. (You could say we KANGED pershoot and just added two frequencies above his)
The frequencies in the kernel from 1113300-1152000 are at stock voltage(1.3v), and I have included the relevant source files. As such they "should" be safe. You never know though! The frequencies below this are Undervolted down to .925v!
This is using SLUB allocator and Deadline IO scheduler.
The recommendation of Team n0ob, is to use set CPU to set your phone to a frequency below 1.11ghz unless you need the extra power for something. Otherwise your battery life will suck and you will stress your processor for no reason.
This is confirmed working on CM-5.0.6-N1.
WARNING!!! THE LONG TERM EFFECTS OF OVERCLOCKING YOUR PROCESSOR CAN INCLUDE:
1. SHORTENED PROCESSOR LIFE
2. OVERHEATING
3. REDUCED BATTERY LIFE
4. BRICKED (IE DEAD DEVICES)
Mod edit: removed link, till source is link to kernel.
I ask that if you notice anything funny that you flash to a more tested kernel and notify this board immediately. This kernel is at stock voltage, but the increased speeds could have adverse effects. Please let us know if you notice any.
Team n0ob takes no responsibility for any damage that may occur to your device.
Credits: pershoot( thanks for the hard work), Kmobs (same), intersectRaven, Ivan (for beginning optimization trend), Rotohammer(experimental random/music/start fix), Cyanogen for awesome roms (whose source this is pulled from), chris soyars, and coolbho3000, Koush for the anykernel updater.
Team n0ob Testers: jlevey, DAMNiaTX Hell! (Thanks)
Following pershoot, I recompiled the Kernel with VFPv3 Optimizations.
resync to 2.6.33.3, old wifi drivers as everyone has problems with the new ones.
Lowered minV to 925. maxV is still 1.3. Voltages are increased to 1.3 only on the 2 frequencies above pershoots 1.113ghz. The other frequencies are undervolted similar to the Kmobs and or the Pershoot values.
Well, by "lowering processor life", how exactly long will my processor last? Does it depend on my phone? My uses? Im all in it for overclocking, and im very aware of said risk.. But processor life I'm not educated in..

Not drastic. Not concrete figures but I've heard figures like instead of something like maybe 6 years, you may get 4-5 years. The processors are designed to last so long that even things that harm them typically still leave them outlasting the upgrade cycle of the user. It depends on the silicon in your phone as well.
Also, Gr8Gorrilla, does this include CM's latest commits from a day or two ago that fixes the pink cam tint issue?
No telling really. It shouldn't be much different than stock. However, as soon as I say that someone will install this brick the phone and blame me. So I am using it and I have a two year contract with T-mobile, I figure it should make it that far.
This is basically pershoots kernel plus 38400 khz. (pershoot in no way endorses this kernel). Take that for what it is worth. The top three voltages 1113, 1132, & 1152, are at stock voltage (1.3v).
I resynced my repo last night before compiling this.
Damn nice kernel is all I have to say

Ok thanks! Definitely flashing this now!
Stock voltage is actually 1.275v. The processor is, however, rated to handle 1.3v (it was originally going to ship at 1.3v, but qualcomm decided to have it ship at 1.275v instead)

I stand corrected. I should have said stock max regulator voltage. I will update the OP.

Nexus FireBall 1.15GHz.
I will be also flashing this kernel update to 1.15 GHz tonight. I want to try and optimize my nexus one to its fully potential capabilities. : )
Updated, Changed Kernel optimizations. Since this kernel follows pershoot, he recommends if you are on 5.0.6 to flash the VFPv3 optimized version.
VFP works great
Hi guys when i unzip their 4 files i know the ko and zimage but the other 2 files do i need to install them too?? and how? thanx in advance.
The other two files are the source files. They there so you can research what changes I have made in the voltage and frequencies and also you could compile this on your own if you want.
Samsung Fascinate CDMA
Rooted MIUI 1.9.16
Did a brief search here looking to understand how to operate overclocking kernals, but find it/me relatively limited.
I have installed and ran Glitch v11 and v12, played around with HL to LL, and made adjustments to undervoltage utilizing Pimp My CPU and Voltage Control. I have also ran Tweak (though not really a kernal).
My question is this,
am I overclocking when I reduce voltage on Mhz's above 1,000?
If not, could someone point me to, or explain how to achieve overclocking on our phones, and
which kernel and governor do you prefer for overclocking?
As an ammended note, I've installed Tegrak Overclock, but am still looking for a user guide...
Thank you for your time.
If you're the running the glitch kernel...use voltage control, not tegrak overclock...over clocking is when you turn the CPU speed above its normal speed..anything over 1GHz.
under volting is when you turn down the voltage frequency to achieve better battery life...
Any one clock speed may perform more or less stable with different under volting unfortunately all of our phones will vary in performance so one setting that works for one may not be the best for another so experimentation is really the best option...this applies for schedulers and governors as well.
I personally overclock as high as I can until it freezes or crashes..then I go 1 setting down...I then try undervolting different steps observing the stability of my phone...when I find what I like,I run it for a few days, then if its still nice and stable I will apply on boot.
The different leakage values are affected by the hardware quality of the chips in our phones which also vary..I start with high and see how high I can overclock..note the setting, then try medium..see how high I can overclock and so on...just as a reference..high leakage creates the most heat and is the least efficient, but works for most phones, while low leakage is the most efficient and generates the least heat and will work with not as many phones

How do you over-clock using Glitch and Voltage Control? I see that Voltage Control goes up to 1,300Mhz, but it's at 0 above 1,000Mhz and can be dropped down to -200mV. Is overclocking just the process of decreasing that voltage on Mhz's above 1,000Mhz's

come on man.. Clock speed (mhz) and undervolting are 2 completely different things.. Forget the voltage.. No changing the voltage is NOT overclocking.. You overclock by changing your maximum clock above 1000mhz which is stock for this phone.. Try long pressing 1200mhz and selecting set as max.. Now your overclocked to 1200mhz..
Sent from the fascinate that holds the record benchmark on antutu
No decreasing the voltage is simply undervolting whether it's over 1000 or under. The idea behind undervolting is increasing battery life, but you can't necessarily go and set each level to the maximum undervolt (200) you half to see what works. Increasing the processor speed is overclocking, stock speed is 1000 so anything over that is over clocked. As far as how far as how far you can over clock depends mostly on 2 things, 1. the kernel your using, ( for example if it shows 1300 in the list that means thats all that specific kernel supports) 2. It varys greatly between phones. For example with glitch you can overclock to 1700 but very few phones can run that high for longer than a few minutes!
Hope that helps.
Sent from my SCH-I500 using xda premium
Yes.. And the fact you say your running glitch and your max oc is only 1300 my guess is you broke your kernel with tegrak overclocks module.. Delete tegrak and stop downloading overclock apps. or any other root app unless you know fully the consequences first.. If after deleting tegrak, and rebooting, if your voltage control don't show a maximum clock of 1700 mhz, then you will need to reflash your glitch kernel

Neh4pres,
Yeah, I kind of feel like a heel. For some reason, I had a brain fart when looking in the 'General' section of Voltage Control. I see now how to overclock.
Regarding ost #6:
When I flashed MIUI 1.9.16, I did not install any kernel; so it was kind of a half truth in that while running 1.9.9 I did have Glitch installd. Nevertheless, I still have Voltage Control installed.
mkropf,
I see that now, and thought as such earlier, but needed some clarification.
Having so many issues with Glitch and 1.9.9, I'm hesitant to install Glitch, but interested to see if it runs better on the newer MIUI...
Thank you two for answering my newbie questions.

Re-installed Glitch v12 ML last night and have it overclocked @ 1,200 with no under-voltage...yet. Want to see any adverse effects.
I started at 1,300 and it locked up then rebooted within 5 minutes.
A concern I have is that now my phone will not Auto Rotate to Landscape even though I have Auto-Rotate 'on' in Settings.
I've scoured Sixstrings Glitch thread to no avail. Though it's not needed anymore, I also flashed the cleaning script just to see if it would make a difference.
Is there a work around or fix for this?
Make sure you're on the latest 9/15 version of the kernel. Anything before that will kill all of your phone's sensors.

For some reason, every time I accessed the keyboard for Google+, it hung, then froze, and 3 of the four times rebooted. The fourth time I needed to remove the battery to reboot. So I re-flashed MIUI 1.9.16 (effectively removing Glitch) and have 0 problems.

You wouldn't want to use my voltages, I put everything way lower than anybody else does or recommends and am just lucky that it is stable for me but it causes the sleep of death for anyone else.
For comparison, just run JT's kernel for a bit and then flash glitch and try it... once you play with OC/UV and voodoo color you won't be able to go back. (you'll be able to but you'd have to be insane.)
First I am aware that overclocking is not "safe" and all that kind of stuff
However for some reason I am unable to OC my SGS2 and run the phone on a steady way.
I have tried several ROMs (stock and custom) with different kernels and OCing apps with no avail.
I am not even able to run at 1.4Ghz or 1.6Ghz without having my phone reboot or hard lock on me.
Is there a particular or recommended setting (most successful combination) that anyone out there can suggest me trying?
Sometimes it will hang under heavy gaming but sometimes even browsing app and regular stuff will cause the phone to reboot or lock. If I work with no OCing at all then everything is fine and dandy.
Thanks, you can see my current configuration @ my signature.
Sounds like a very temperamental cpu. Currently I have the same setup you do and have never had issue with 1400mhz or 1600mhz. Though I usually leave mine at 1200mhz. What app are you running when it hangs?
And just as important, do you have alot running in the background? The modified touchwiz launcher unnamed comes with can be enabled to show a red dot next to the apps that have been opened and are in the background.
If you could list the apps with the red dots.

Not all CPUs can overclock - there's a reason it was sold as a 1.2 GHz chip.
Well as I've mentioned before, it could even hand when browsing through my apps menu, browsing the gallery, playing a game (non in particular) and the funny part is that the phone is not even hot to touch.
What I know for sure if that if no OC = no hangs, no reboots.
I do have the App monitor widget that comes with the stock ROM and currently using it on UnNamed 1.3.1 and I only have Widget Locker App. However I have try closing it and still will happen.
Not sure if maybe this CPU is somehow having an issue that makes it unstable as soon as I OC it.

Now that is new to me, I thought that all of them were OCable. Is there anyway to identify which can be or not OCed?
nope.. just by testing. it does have to do a little bit with the kernel and rom. the roms didnt originally have stable OC. i would assume that all of them do now. one thing you might try is giving them a little more voltage (just a little) at the higher clocks, but be careful. if you increase the voltage that means that you will sink more enery through the cpu and it will get hot quick. make sure you watch the temp.
i find that setcpu is less stable than the built in cm7 oc menu but cm7 doesnt have a voltage menu.
but on the same token... why OC? i can and i did but i dont need to... everything is like butter and i didnt see that huge a gain by OCing it anyways

have you ever overclocked PC CPUs? if you have spent much time doing that, then you would know that not every chip, even within the same model/family, will clock the same. take 2 CPUs, from the same batch, same model, with identical hardware tied to them. you will probably find that one clocks higher stable speeds than the other.
its very likely the proc in your phone just cannot handle the overclocks that the next person's could.
Like pirate said, no two pieces of hardware are identical. Sort of shows how much variance there can be in a manufacturing process. Id guess theres a few chips that come off the same line that arent stable at 1.2 ghz, but they dont make it to the devices, whereas one that can handle a higher clock will. (No sense tossing one that exceeds minimum requirements, thatd just be throwing good hardware away)
You could try nudgin the voltage up and seeing how it behaves, just use caution.

To get mine to overclock to 1.4 and 1.6Ghz I had to actually INCREASE the voltage settings via Voltage control app. So my settings are: 1.6Ghz= 1475mV and 1.4Ghz=1325mV
Try those out and see if is better for you. I tried undervolting the higher voltages and would either lockup or reboot instantly until I tried adding voltages. So you may need to play with your settings to get it to work for you.

Yup, or if they want to sell a "premium" device with a higher clock rate, they will take the parts that test well at 1.4 and sell them as such - meaning parts rated 1.2 will be LESS likely to be overclockable if a device comes out with CPUs rated at 1.4 - like the Galaxy Note did.
Before, anything that could meet the requirements of stable at 1.2 was sold to any Galaxy S II - but now, the premium parts are going into the Note.

I am having the same issue as the original poster on my new GS2. I will have to try the settings you mention but would it be possible to do this and also apply /UV to the remaining lower (1000ghz to 200ghz) processor speeds and maintain stability?
Hey guys,
I have just installed OmegaRom by Team Cooper and what a Rom it is!!! Amazing is an understatement.
Okay so with there new Rom v2, it has an OC kernal built in and it does work...BUT I need to know how to OC the thing safely and squeezing as much performance as possible!
I have it at 825 and min 806 mhz, scaler is performance.
What settings would you pro's recommened?
Thanks!
Edit 1- I am using SetCPU to OC.
"overclock" and "safe" cannot be use in the same sentence, it just wrong.
theres no safe overclocking. moreover each and every device is unique even for the same model.
what is working with others doesnt guarantee it'll works with yours.

I don't Think U mustuse over clocking,even my setting was min245 max 902,the effect just draining more battery,and if using to much can damaging ur prosessor
I know you might think what I'm going to write is unnecessary and going to contradict with your believes here. but I'm going say it anyway.
If you are going to use your device for a long time then I would suggest not to overclock too much. You'll know when something will go wrong with your over-clocking. Your SGA would start rebooting randomly. Heating up would be excessively common once you start overclocking, using your SGA while it's charging. Over clocking will definitely reduce your processor life span. People who do can over clock their device to get the max out of their device and know they're going to change the device in sometime later anyway.

I know you might think what I'm going to write is unnecessary and going to contradict with your believes here. but I'm going say it anyway.
If you are going to use your device for a long time then I would suggest not to overclock too much. You'll know when something will go wrong with your over-clocking. Your SGA would start rebooting randomly. Heating up would be excessively common once you start overclocking, using your SGA while it's charging. Over clocking will definitely reduce your processor life span.

Don't worry! Like I said, I have experience O/C'ing processors etc and I know how bad the effects can be! I am not going for a massive overclock at all. Just a tiny bump in the speed. At the moment, I am running 825mhz and already the speed has improved dramatically. I may go a little further but 902mhz is a bit mental for my liking.

I try CPU Tuner, is similar ti setCPU but is free whit THE END 3.0 custom ROM and use the 864-254 mhz for screen on and 480-122 for screen off whitout problems, previously I use 904 mhz, but sometime it freeze...

SetCPU is free for XDA members and it's the best one ever...period

setCPU is free to if you download it from the forum
These settings have been tested by me all night and all day checking the timesnin each clock state and if it failed it would be a simple fix . This is as stable as can be lowering your temps and increasing batterylife!! No more screen dimming. I stopped the undervolting process at 1728mhz because at 2265mhz regardless the phone would overheat
So here are the specs below
300mhz----750mv
422mhz----750mv
652mhz----750mv
729mhz----750mv these are as low as I could go
883mhz----760mv
960mhz----770mv
1036mhz---780mv
1190mhz---790mv
1267mhz---800mv
1497mhz---810mv
1574mhz---820mv
1728mhz---830mv
These settings are to be inputted directly into setcpu via voltage table proven to work
These settings are also tested daily and improved where flawwed
I figured i would post this since there isnt a single post with manual voltage specs
Good info thanks!
You got it!!
Have any voltages setting for OC?
Are these settings good for gaming?
As posted these voltages are strictly for batterylife however does just fine on gaming. I will work on oc voltages once the cpu limiter is removed from any kernel unfortunate it would be pointless to overclock this handset
Why can't I adjust voltage settings on a stock kernel? I don't get an option to do it in the fauxclock app...

you do know we already have 2 over clocked kernels for tw. so its not exactly pointless.
These settings are for people who want batterylife and to enjoy theyre phone without the screen dimming on them from the cpu overheating on them.. i dont see a point in overclocking the phone. Maybe some quadrants and horrible batterylife
There are some that want the most battery in a device. Others want the most performance. I and others are in the 2nd category. I personally have a zerolemon so battery life is a last priority for me seeing that underclocking this handset is pointless to me. But to each their own. I do aprreciate you taking the time to find out these voltages but to some OC is just as addictive as flashing roms themselves lol!
Thats fine you can enjoy your screen dimming 2.7ghz while i have the zero lemon and underclocked at 1728mhz and undervolted lasting 6 or more days and still screaming fast. Sure there isnt a point to it huh

Thanks a lot for this
MY NOTE 3 BETTA THAN YOURZ
does any one have the stock kernal voltage to maybe compare
i tried these settings
set up fine
300mhz----750mv
422mhz----750mv
652mhz----750mv
729mhz----750mv
883mhz----760mv
960mhz----770mv
having issues on this half
1036mhz---780mv had to set to 800 because it kept freezing blacking out
1190mhz---790mv 820
1267mhz---800mv 850
1497mhz---810mv 885
1574mhz---820mv 900
1728mhz---830mv 915
Stock Kernel Nope.
This WILL not work on a stock TW kernel as SETCPU or Voltage control do not have the ability. The only way to change voltages (unlike the title claims) is to flash a NON stock kernel first.

This is due to variation in chips, when the processors are manufactured they are tested, separated by performance, and priced accordingly (this is called 'product binning'). Those of you using OP's settings with no issues have similar or better processors, and likely could undervolt further.

yes true and i understand
my only reason for saying that is he has a note 2 in his signature plus we have a 2.3ghz processor soo y would it overheat?
plus our cores are handled bit different because we have a snapdragon and well the note 2 has a exynos processor :fingers-crossed:

The clock speed, voltage, and heat are all directly connected; changing any value will affect at least one of the others.

These theories are equally applicable to all processor types. The issue with these one-size-fits-all settings is we are using cpu's from multiple different bins, thus they can tolerate different voltages/clock speeds. It's also worth mentioning that 2 cpu's from the same bin will tolerate different settings (as they came from different wafers) and that even 2 cpu's from the same wafer will likely tolerate different settings (depending on it's location within the wafer).
In other news, I've found THIS extremely useful thread that explains how to go about revealing your bin # (Thanks @toastido for noting that KitKat changed location to /sys/devices/system/soc/soc0/soc_pvs :highfive. The thread also has multiple users end settings and benchmark results.
Last but not least, to finally answer your original question: I found in that thread that your original settings will vary depending on your bin # (There are no universal stock settings) but perhaps you can find someone who posted their original settings from the same bin that you have. Hope it helps, cheers :good:
