[Q] How big pottential is for Underclock/UV? - Galaxy S III Q&A, Help & Troubleshooting

I got galaxy s phone and is pretty annoying that when I choose clock 400MHz phone hang up while screen off.
I think with good launcher on 4 core I rly don't need more than 200MHz clock. Games Like Nova 3 are fluid on even 600MHz clock, OFC limit here is GPU...
How about SGS3? How low clock and UV are possible to set up.

it is possible in s3.flash a custom kernel and use tools like voltage control or setcpu or nstools to UC?UV

How low clock can you set? Is it stable? On SGS when screen have gone off at max 400MHz, phone did not wake up.

SetCPU x10 mini Settings

Could anyone please tell me the settings and profiles that will give my x10 mini the best battery save? thanks
actually there is already a preset for that ..the "powersave" one..
Easy, just put both bars in 122880MHz..
Your phone are going to be rrrrreeeaaaallllyyy slow, but you save lots of milliamps
Use ondemand only. And set min to 122 and max to 600.
I use a profile when screen is off that set min to 128 and max to 320, ondemand too.
Step 1: Once the app has downloaded from the market open it.
Step 2: Hit auto recommend speeds on the first boot up of the app.
Step 3: Click the profile tab at the top.
Step 4: Hit Add Profile.
Step 5: The profile button selects what happens for the CPU to under clock or over clock. The max is the max the CPU will reach; the min is the minimum the CPU will reach.
Step 6: Profile: Screen off. Max: set to minimum. Min: set to minimum. Scaling: set to Conservative. Priority: set to 100. Press okay, and hit Enable.

Has anyone had problems with random freezes and reboots with SetCPU installed? I've had a couple random reboots, so for now I've uninstalled SetCPU to see if the problem goes away. I also have Advanced Task Killer installed but it wasn't set to kill tasks automatically.

Setting SetCPU like that is not very smart. For example, You have Your screen off, someone is calling You, what happens? You get the call ringer after few seconds (sometimes even 10-15!). Reminds of old Symbian versions? But just this. Next example - You have Your screen off, and You receive sms. What happens if You are using Handcent, and have to go to the app manually after phone wakes up? It takes ages... But if You have more than 1000 massages in Your inbox, and a new one come, and You get it after screen wakes up it can even lead to a reboot.
Lets add some random weird situations if You are listening to Your player while the screen is off... using some third party apps, etc...
Setting the minimum CPU for the screen off is not a good idea. Don't do that, or the phone will fail You in most unwanted cases.
so what are you guys using?
I am 122-600 on normal ondemand
and screen off on 122-256 ondemand
Anyone with better profiles?
just dont overclock!!!
why not? I see you are running 729/600.
WHY is your min 600?
Use smartass governor - auto profile, just upgrade to gingerbread.. best profile yet..
Set normal use 122Mhz-729Mhz 100% Priority
Set for charging: 122Mhz-245Mhz (or similar) - 100% Priority
Set for screen off 122-245 (or similar) - 100% Priority
^ this saved me battery when I used my phone for so much else besides calling and texting.
for good batter backup....set the minimum as 122Mhz and the max as 480 Mhz....anything above 748 and below 480 will get u into "restart & restore"...however, there is a overclock module allowing you to overclock to 825 Mhz (but dats juss fr "testin"...u'll lose battery like a freak and will get awfully hot readings)

Only a handful devices supports being clocked to 825Mhz but it's very dangerous.
I doubt you can raise the clock speed to 825Mhz without the phone freezing up.

Some have succeeded, but I doubt their phones lasted very long after that.
Just wondering, is the phones processor under the right side of the keyboard? cause after a few minutes @ 710Mhz, that area is hot. Since I switched to the smartass governor, it rarely is hot anymore (due to the fact it mostly spends time @ 245/320Mhz
Um... question?
Shouldn't the phone go into deep sleep when the screen is off with no cpu activity?
Also install cpu spy and see what the cpu is doing for how long.

1. The cpu does not make the most heat... it's the 3G radio.
2. Cpu should deep sleep automatically.
My OC prifile for mini pro:
Standard profile- 122 - 825mhz
If Battery < 15% then 122 - 600 "this gets rid of crashes due to low power OC"
Also.. i asked some of the developers that made the modules for overclocking and undervolting.
It's undervolting there is no upward voltage bump so it can't really nuke a cpu.
But you can nuke the power circuits if you use heavy internet on 3G and charge at the same time.
How can I put over 600 Mhz?
My SetCPU makes 600 Mhz the max. I want to put just on 700, but I can't. What is the problem?
@Felimenta97:
You don't have any overclock-enabler module installed/insmodded or if using any CM-based ROM, the corresponding setting is disabled.
I'm using smartass with 122-320 for screen off and ondemand with 320-729 for normal, no problems so far
The max MHz I could get was 729MHz, 748MHz worked but after some time the CPU got 'pegged' as said in the logcat
Tried the 825MHz setting that only caused a freeze and boot loop, forcing me to do some fast adb commands to get rid of the overclock

[Q] Best Setcpu profiles?

Hello,
I am wondering what the best Setcpu profiles are for SGSII when you want performance while awake and save as much as possible in Idle.
Can I put it all the way down to 500mHz while screen off and still be able to run background processes properly?
I don't really see why this shouldn't work. I had it set like that, but I also have it set to 500MHz when active quite often, as this is enough for many applications. Still, that might not be necessary, as it resides in this state quite much of the time anyway.
Since I have undervolted my phone recently, I had to set the "screen off" profile to 800MHz so that the screen comes up (otherwise, it wouldn't). But in the end, it probably doesn't matter too much what you have set for that profile, as the phone should be sleeping most of the time anyway, shouldn't it?

Profiles are useless, the ondemand governor should scale down your cpu by default when not in use, that' s the whole point of this governor!

ICS kernel CPU throttle

I am starting to believe that the ICS kernel scales properly although some people may claim it only scales from min to max.
I noticed on the stock GB kernel, the exact same thing happens when trying to use CPU controlling apps such as setcpu. However, for BOTH GB and ICS without using CPU controlling app, I can see the in between frequencies being used. When I try adjusting the slider THEN it starts the freaking out in terms of min/max. (Rom toolbox)
I even notice the battery life worsen tremendously when trying to use setcpu, antutu, etc on STOCK frequencies. Perhaps it has to do with people trying to use CPU apps on a kernel with the perflock enabled?
With the absence of a CPU controlling app on ICS , my battery can last the SAME (not worse, for sure) as it on GB.
Perhaps this can help those who complain about bad battery life on ICS
Sent from my ADR6425LVW using XDA
You don't need to wonder anymore! Its a function built into HTC kernels called "perflock" and its function is to continually reset the values for the min and max frequencies in order to prevent other applications such as setCPU from taking control over the CPU frequencies.
I've been using SEbastianFM's ICS OC kernel with setCPU. You are correct, that it does scale properly even though the min/max frequencies hop around. If you take notice of the current frequency, its usually appropriate for the current load level.
Furthermore, if use setCPU profiles to control the CPU speed, I've noticed it prevents the kernel from periodically reverting back to its default speed and governor settings. setCPU occasionally crashes (FC's) about once a day on me, but since I have the widget on my homescreen I notice it starts right back up again within a second or two and starts controlling the CPU speed again.

Using Tasker for CPU control?

I would like manually create settings for when my CPU is overclocked and underclocked and I was hoping to find some help with this. I want my phone to underclock to roughly 800mhz - 900mhz when the screen is off, battery is bellow 20% and when the phone is above a certain temperature and overclocked to 1.1ghz at all other times. How would I go about doing this? I am new to tasker and there doesn't seem to be an option for CPU controll. If someone could advise me how to do it, rather than just direct me somewhere I can download a profile, I would appreciate it.
I am using a HTC Desire with VJ's CM 10.1 rom (performance control is not in settings as of now, using daemon to overclock)

[TIP] Music lags while locked? Don't worry! [13/03/2013]

Have you ever faced and issue with music while your phone is locked?​
Don't worry! I had them too! They're caused by the minimal CPU frequency. Set your min frequency to 245mhz instead of 122. That will fix your issue. Here's an awesome app that will help you to adjust your CPU, GPU and more!
