Basically I have the stock 3.70 rooted and all types of stuff. What I want to do is use a kernel that has the overclock set to a frequency 100% of the time. I dont want to use an overclock app.
If possible, are there any stock(based) roms that are overclocked out of the box, without the need for an overclock app? Ideally I would like to flash a kernel on the stock that I have now and have that kernel run the clock speeds at the overclock speed, for example 1.2ghz(example), 100% of the time with no throttling or governor.
thank you in advance for your input.
umm.. ..excuse my ignorance but why in the hell would you want to do that?
So your saying when you and your phone went to sleep you want to be max oc'd....
This is easily done with setcpu profiles and I don't think its a good idea just on battery life alone let alone stress from constant oc
swyped from my cm7 w/4G
Thisss , would kill the phone. No doubt at all. Even no over clock running at type clock 100% of the time would kill the phone..

Does anyone know how to over clock you're DI to say 1.2? Thanks for any help.
You first need to root your phone, then install a kernel that is compatible with whatever rom you are using, then you need to install an OCing app like SetCPU and adjust accordingly.
I'm rooted running the 2.2 RUU and I have set cpu. So do I just need a kernal? Which one?
i reccomend King Kernel bfs #4, best freaken kernel ever... its located... here
so when i install this kernal is it ok to just bump the cpu speed up to 1.2? are there any guides to do this?

A lot of factors come into play when you start overclocking, every rom will respond differently.
The first thing to do before anything is to do a complete nandroid back up.
When overclocking keep in mind that the more you overclock the more chances you have of making your system unstable.
I have experimented a quite a bit and I have found that the King Kernal #4 seems to work well for me and at 1.2 it seems to be pretty stable. Any higher than that and my phone will sometimes re-boot itself for no apparent reason.
Again, your rom may handle things different so experiment and see what works best for you.
And remember - Do a complete backup first!
I'm using the number 4 kernal and it only goes to 1.19 is this what you mean by 1.2? I have to keep mine at 1.1 ghz at 1.19 my di gets unstable
Ya that's as high as they can oc these chips. I can only get to 115 safely 119 just crashes. But the charging experience will be better than stock with the BFS #4.

Could you guys please tell me what your settings for setcpu are?
I want better battery life and a faster cpu but im noticing that my phone almost needs a wake up time when i come out of screen off.
Thanks so much

If you are experiencing slow wake up, try increasing the min cpu speed to something around 460. Better batt life and increased speed takes a lot of experimenting. Your OC speed might differ from others due to differences in the phones cpu. For example, I have never been able to oc to 1.19 without the phone freezing or rebooting. My phone can handle 1152 but 1113 is perfect. In my opinion, ROMs have something to due with best batt-speed combo. I am running Ruby 1.1.1 with a setcpu profile of Screen off=245 without any wake lag. Other ROMs I have tried had wake up lag at that speed profile.
My set up:
(ROM-ASOP) Ruby 1.1.1
King's #1 ASOP "I told you so"- only works with ASOP
With the ROM's "Gem" performance scaling setting off, I use setcpu to OC to 1113, min is 245. I have a profile set to SCREEN OFF = 384 max/245 min.
I haven't worried about battery life since I started using King's kernals (I've tried them all with every compatible ROM on xda). I have several posts elsewhere on XDA showing 12 plus hours on a single bump charge and heavy phone use. Good enough for me. Stock cpu speed plus Sense ROM seems slow to me now.....to each his own though.
I hope to get some help because i value the opinions of those on this forum. Currently i am running virtuous 2.7 with virt. kernal v2. I am rooted, s-off, 2.15.xx radio. I want performance without draining my battery. What are the best settings to use in setcpu?
I did try king's kernal #4, but it was rebooting. switched kernals this morning.
One other app I use in conjunction with SetCPU is MinFreeManager. This will readjust your free ram to a higher standard. But with SetCPU I have it at 1113/Ondemand with no custom profiles. One other thing I really don't set is the Set on Boot option. I don't know why but I do. So with SkyRaider Vanilla 3.0 RC3/ KingX Kernel #4/ and MinFreeManager my phone fly's. I can't say for certain what settings you need for your phone but 1113-1115 is preferred by "most" phones and keep the set on boot option off. I keep a Galaxy S live wallpaper running and pandora while browsing the web and no lag what-so-ever.
CyanogenMod 6.0.2 and KingX kernel #1 with the same setup runs almost as smooth.
Hope this helps you out.
I am new to the setcpu app I am wondering how do I know how much frequency my min and max should be to help my phone out more. Can anyone help me on that plz?

It will depend on which ROM and kernel you're running, but generally, overclocking doesn't do much good for you. I do however run my Main Max @ 1113 and Min @ 245. I then have a profile set for Screen Off Max @ 245, Min @ 245. This has helped a lot with battery life. This is on CM6.1.1 and the SBC stock kernel.
Also, there are the Scaling options. They will vary based on the kernel you're using. Generally, their names speak for themselves, so pick appropriately. I use Interactive when available, or Ondemand as a second choice. If you choose Performance, you will stay clocked at the highest speed until over ridden by a profile, so don't bother with that one unless it's for testing only.
One thing to think about is that Setcpu doesn't play well with HAVS, so if you're running a kernel with that built in, they will be fighting each other.
Also, if you're running a stock based rom with a stock kernel, you will need to disable Perflock if you want Setcpu to be able to really do it's job. So, while in Setcpu, tap Menu > Perflock Disbaler and attempt to disable perflock. Once it is successful, pick set on boot and close that window. Now Setcpu can work properly and you can start saving battery.
If you're primary goal is to get amazing battery life, I highly reccommend you try some of the new SBC kernels that have trickle charging built in. That's what I've been using since they came out, and it is amazing what a little tweak can do for you. SBC Kernel Thread
What are the safe/stable clockspeeds for underclocking and overclocking my Desire Z? Also, what app do I use? Like, I don't mind paying for the app (as long as it's not too expensive)
Sent from my HTC Vision using XDA App
SetCPU can be used to overclock if you're rooted. Depending on the ROM and Kernel combination, overclocking to about 1.3ghz is usually safe. Some go up to 1.5ghz or even 1.8ghz, but are often quite unstable depending on other configurations you have in your ROM.
As far as underclocking goes, some custom kernels clock all the way down to 122mhz, I've been using a streamline5 kernel on CM7 (which offers 122mhz min) and haven't had any ill effects with this.
I have the Virtuous Sense ROM (with it's default kernel, although it does have other kernels which can give other cpu speeds), right now but might try out another ROM soon (maybe) do you know what's the min and safe max for this ROM?
Also, can I just set a particular clock speed (e.g. 500MHz) and it should be ok or is there any stability difference between say 500MHz and 505MHz? Just curious. I looked at SetCPU and it looks like a good one. Also, if the clock speed I set makes things go wrong, can I revert it or can I get stuck with it and need to do a wipe?

No, there's no need to set a particular clock speed. Just whatever works for you. I wouldn't recommend going under 800mhz, as the phone will really really bog down even with normal use.
I haven't used that particular ROM, but I'm assuming anywhere around 1.3ghz should be safe on the upper limit. Like I said before, anything above that might start to cause issues. You might also want to consider the battery life implications of severe overclocking.
You can change the clock speed any time you want. If you're having wakeup or heat or any other issues just go back to SetCPU and change the max clock speed again. You can also use profiles in SetCPU to change the clock speed when the phone is overheating, or when the screen is off, or when the battery gets to a certain %. There are tons of posts detailing how others have setup their SetCPU profiles.
One last note, don't forget to check the box for "Set on Boot" in SetCPU, this way your changes aren't undone on reboot.
Thank, I think I got everything I need to know in your last reply
I'm on CM7, with the CM7 kernel, and clocked in at 1.5GHz, and have no problems, and the rom is super fast. And I use SetCPU.
I'm quite happy with the stock ROM. Is it possible to overclock it? Do I just need to install a overclockable kernel? Will I lose any functionality due to bugs/etc? What's the most reliable kernel for O/C?
Thanks,
Nick
It is possible to OC it only via a custom kernel.............so i recommend that you try the Dust kernel by einstein.frat
Yea he's right. what you need is only being rooted and recovery for flashing kernel..and of course a program which controls your cpu such as setcpu..
i recommend you kernel that cm7 used with last update. it supports 864mhz even and with no stuck( and battery drain )if you search for it on xda i am sure you will find..

In any way......DO NOT use the CM7 kernel...........an AOSP kernel is a bit different from the Stock(sense) one.................................it won't work
Thanks all. It looks like I'll give the dust kernel a try.
Are there preset CPU MHz settings for overclocking or is any integer value allowable? Most of the overclocking threads talk about 768Mhz, 806Mhz. My guess it's probably constrained by some clock multiplier factor.
oww i am happy to learn that
Plzzz reply which wills sbe the best overclock kernel for stock miui 12
Every time I try to underclock the CPU as soon as I leave the app the sliders go back to where they were originally. Even after applying on boot. Am I doing something wrong?

Since you've given virtually no information, I will assume that your phone is unrooted and/or running with the stock kernel. You will need to address both to be able to underclock.
Because underclocking is silly.

I'm not running EX. Does it use init.d or config script? Those may overwrite whatever method you're using to underclock at boot.
Underclocking-saving battery
Is a BIG LYE
CPU will not use full power (max freq) when not need.
Dont forget what is Mhz (how MUCH things CPU can do in what TIME) the only deffrent bettwen underclocked and overclocked is TIME.312Mhz will do something in 5 mins,but 2 Ghz will do it in 1 second. It just do faster,but battery use is same,count yourself
1. You warmed up a dusty thread.
2. Battery-work isn't simply product of time and frequency: longer low tasks eats fewer capacity than shorter peak ones.
