Since all this new hype about the phone being rooted has been coming out. Theres on thing I've been concerned with since I've planned on getting the phone. Will we be able to use Setcpu once root is released, and if so can we immediately clock up to 1.5ghz? Is it in the coding already, or is this kernel just officially set at 1.2?
I figured someone might have an answer since they achieved root through the kernel and have poked around in there
We wont know till we all have root. But I highly doubt it, we will most likely need a custom kernel to enable overclocking. and having root doesnt give us kernel source code.
Bah! That's right, I've been so used to having everything available w/ the Evo 4G that I forgot about source code...
Any thoughts on the actual functionality of Setcpu though? Because I know for some phones/kernels Setcpu does not play well (or even at all sometimes) aka early times w/ Tegra 2's (even though their NAND and source coding were completely different)
I'd stay away from SetCPU for the time being, even if a future kernel supports overclocking. Our CPU has two cores with totally independent core clocks, so an app that is only designed to control a single clock wouldn't even know how to deal with our setup.
If I were you I'd try to let go of the old mindset of "faster, faster" and focus on getting rid of bloatware and generally streamlining the OS. This phone is already so fast that overclocking isn't going to accomplish anything except burn the battery faster and maybe return some slightly higher benchmark scores, but you probably won't notice any improvement in speed, because how can you get any faster than "immediate"??

With the flux capacitor they just released of course, dont you read the development forum?
But good point about all the other programs being made for 1 core OCing. We probably wont be able to use anything to overclock with until someone releases a version specifically for this phone.
I prefer to use these programs as a way of undervolting and limiting speed to get better battery life rather than overclocking for more speed.
Well until an optimized ROM and s-off was cracked I just wanted a little more oomph to get sense running a little smoother but I really have no complaints withthe phone. Just wish sense was a little smoother. (Yes twss)

Once we get custom roms without all the bloat I am sure sense will fly

I completely agree, because it ran decently well on the OG evo =)
Right now the jump between 1ghz to 1.1ghz shows no real world benefit. I have a couple of questions:
1. Does overclocking to 1.1ghz effect the battery enought to see a difference?
2. Does undervolting save battery enough to see a difference?
3. If i have a custom kernal but still running at 1ghz, will the battery be the same/worse/better then runnning 1ghz on stock kernel
4. Does undervolting have any negative effects on performance
Thanks in Advance!! XDA RULES!!

Not trying to be rude, but does not answer my question. Why go through the procedure when someone who has already done it or has experience with it is kind enough to post answers.

1 Yes it does, but the phone only uses that frequency when pushed to limits, so not much.
2 Yes, i believe it does.
3 I found faux kernel to drink my battery like water even oj stock clock. Edgan's didnt have that problem.
4 it may cause random reboots if ur UV lvls are beyond the phone's capabilities.
Ps1: hes got a point, all impressions are too personal, they dont translate to universal experience.
Ps2: the greatest use of OC on the atrix right now is the webtop, that really pushes all possible processing power.

Thank You!
Anyone have a ultimate setting for saving battery life in SETCPU for the Motorola Photon?
Bump.. Just bought it myself will read more into it... But if someone has a quick down and dirty on settings for the photon would be appreciated... I did do some initial settings but felt the screen was getting too hot so I aborted the settings I applied.
I stopped using setcpu back when i had an HTC hero (2009). You really don't need it imo lol. Wanna save battery, use an undervolt kernel or turn off mobile data when you're not using it. You could also turn off auto background data sync.
Will look into it, just seemed that the percentage based rules looked attractive inthe program.. Always nice to be able to apply less than rules, greater than etc..
And if you're drinkin' well, you know
That you're my friend and I say
I think I'll have myself a beer
Don't think an app can control our cpu. I've tried setting frequencies only to have them ignored, pretty sure some programs will have the under volt ignored.

Set cpu undervolting my photon def works.. I did notice (not recently though) that under a lot of stress while undervolted itll kick up to a higher voltage though I havnt seen it do that for a long time now..

So there is or is not good reason to use setcpu on the photon?

Its all based on the personal preference man. If you feel the need to use it go ahead. Myself, I don't think its necessary. I mean it's good for setting profiles in different situations (screen on/off,charging etc). Most of the time the kernels baked in settings are good enough but some people combine a custom kernel with setcpu for maximum control over CPU. Setcpu is absolutely pointless unless you're running a custom kernel. Plus if you use cyanogen roms it will allow you to set CPU values within the rom. Again, these are just my thoughts on it man.
Well I'm in the process of trying to get CM9 working, so I guess I wouldn't need it.
Thanks for the clarification.
Can I ask, how did you UV your cpu ? is it somewhere within the setcpu, or it comes from the kernel ? I really don't understand about ocing/uving an android phone, thx.

Custom kernels will allow you to over clock or undervolt. Set CPU just allows you to set clock speed upon boot along with custom profiles. If you install a kernel that allows undervolting it should have the custom values baked in. Again, use set CPU if you please. Joker has a set of custom kernels both uv/oc. I'm using his 1.3 oc kernel for CM7 at the moment but I'm only clocked at 1.2 just testing out. So far its amazing.

Doesn't voltage control also work? When I was using my Epic4g, i preferred voltage control over setcpu since it does both: OC and UV.
However, I'd agree with kennypow3rs that i dont think any of it is necesary with the Photon. It's quite fast already and the battery life is amazing. I hacked my Epic 4g like crazy, through 10 ROMs, OC/UV, Eclair through GB, and I have to say, it was a waste of my time. I am now extremely happy to have the Photon, stock and rooted.

thanks man!
I prefer to use this instead of the ones built in to cm7/9, personal preference i guess.
But the only real reason i use it is for the profiles feature. Which i set my phone to screen off to max at 216mhz(wish i could auto disable while using Pandora), then to any time below 100% battery to max 750mhz (with jokers kernel that disables the 2nd core) and then finely to run full speed when its plugged in.

where can I find those custom value ? and how I set them ?
and while on it, I want to ask since I'm using setCPU to undervolt, what is the normal voltage of 1.2 cpu clock ? I'm noob at this please bear with me, thx
Funny, I have been using SetCPU until Kennypow3rs said something. Although it worked, I have ROM Toolbox Pro. I figured out yesterday, It does all that performance crap and more. Matter fact, I got 15 hours out of my battery (Granted, 7 of those hours I was sleep!)
Lol.

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.

It does? That sounds more like one of the themes that includes TW4.5.
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

I know, this Exynos processor is the best out there right now, forget about Qualcomm's Snapdragon on the Skyrocket. I am just trying to OC for the fun of it

Although it makes me wonder if the CPU could be having an issue, since it hard locks when attempting to.

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?
Hi, i know this is a stupid question and i have tried to do some research before hand. I have never overclocked any of my android devices, as the worrying that it will decrease you phones life span has always worried me, and the fact that overclocking my old htc desire actually made it unstable. But because the galaxy note had the exact same exynos processor as the s2 but clocked to 1.4ghz. does that mean it's perfectly safe to overclock the cpu to 1.4ghz?
The reason why I am asking is because the galaxy note vs s2 videos on youtube show the note to be noticeably faster in everything. Thanks very much

I run my device at 1.6 with absolute stability. Believe it or not, a lot of the processors released in todays devices are meant to handle much higher speeds, but for battery purposes, they dont push the limits. But to answer your question, yes, its perfectly safe to push it to 1.4, and you probably wont notice any more battery drain then your already used to since they make some battery saver tweaks in the aftermarket kernels. I use Siyahs kernel and its awesome.
