I specified SetCPU to have my speed at 245 min 768 max. It stays there, but then with time goes back up to 998 max. I disabled perflock, should that fix the problem?
what kernel? what ROM?
disabling perflock should fix that
i have some issues also, my evo cant take anything over 998,,it reboots but my brothers work perfect with high setup.. why could that be

There were a few different evos made so not all of them can handle oc'ing there was hw0001 - hw0004 do to the high demand of the evo when it came out something like that.
Edit: Also even the same hw version can be different.

Stock kernel with stock rom (but removed bloatware/rooted system tweaks). Perflock disabled appeared to have fixed it. Thanks!

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 have been bouncing back in and forth from rom to rom. Most are great. Warm 2.2, DamageControl, and Virus (currently running). The issue I'm having is no matter witch rom or kernal I run on my Evo froyo, every time I install Setcpu within a couple of hours my launcher (no matter witch one) stops working. I have gone into root to reinstall, install and uninstall and nothing works. All Rome are affected by what I can tell. I'm finding the problem to be with setcpu. I'm surprised if can't find much information on this. Does anyone have ideas?

Yea, setcpu can improve things but also causes issues elsewhere. I was using launcher pro for a while, and using that in conjunction with setcpu gave me nothing but poor battery life and terrible freezing. I have since then stopped using setcpu and my phone works fine. Besides the difference between 1ghz and 1.1-1.2 is negligible on the Evo unless your benchmarking imo

Stop putting your phone's minimum frequency at 128 or 245MHz. Also, tweak your launcher's memory settings properly.

I did all that already. I had my screen off set to 384mhz, im no novice, setcpu has great benefits but has some negatives also.
OP, try ziggys 10/26 kernel. It has scripts that handle oc'ing up to 1.13ghz using interactive governer WITHOUT using setcpu

I use SetCPU and Launcher Pro Plus and have used these 2 on every ROM I have used...which is a LOT!! My screen off is set to 245 and I OC to around 1228. I have NEVER had any issues on amy ROM. I dont know what is causing your issue but it isnt SetCPU and Launcher Pro....
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 have htc wildfire s ...i hav rooted ...i want to overclock it 806 mhz.....pls tell me the procedure to overclock..
I am using htc wildfire rom ..pls help
First you need a kernel that supports overclocking.
If you using a stock Rom then look for the kernel that matches your Android version eg. 2.3.3 or 2.3.5 you will find them in the development section posted by Jikantaru
If you install a custom Rom then it will most likely have an overclockable kernel baked in.
To change clock settings I recommend 'no frills CPU' search it in the market or you could use set CPU.
Once you install one of the above apps then change the min and max sliders to the desired frequency.
if we over clock it much does it effect the speed or hardware of the phone?
Your phone may hang.
There is SetCPU for XDA members:

You will definitely get better performance and it shouldn't cause you any problems.
Use no frills CPU I find its better than set CPU, when restarting your phone set CPU doesn't keep your overclock settings even though its set on boot.
As for the govonor settings I would choose smartass2 and noop for the scheduler.
I would keep the minimum frequency on 245MHz it can go lower but it could cause some issues (lag and slow unlocking and waking)
Note: not all cpu's are capable of running at the same speed, I'm lucky mine can run at 806MHz but some people have issues.
If you notice any problems like freezing etc, then drop the speed to a lower frequency until you find the sweet spot for your CPU.
I had mine at 806 MHz with no problems

Should be fine mate.
But remember if in the very unlikely event something does go wrong I wont be held responsible.
youll have to need an overclock kernel for that. (and a rom which supports one)
go for dust kernel or cake kernel! These two are well known for high end kernels!
So I just got my galaxy S3 sgh-i747, I have rooted it, installed a custom kernel (ktoonsez Sammy kernel) and installed the pro version of setCPU.
The problem I am having is that even though I set an overclock limit to 1674 mHz, setCPU will occasionally boost it to 1890 for no apparent reason. This causes my phone to heat up immensely and renders it unstable.
I have also tried profiles (one for screen on, other for screen off) yet even with the profiles and notifications I get, the app still acts up. I am wondering if the widget and the app are just glitchy and displaying those speeds but not really setting the CPU at that level...
Here are some screenshots for clarification:
Edit: Sigh.. I cannot post screenshots..
But basically in my screens I show that the slider is set to a max of 1674 yet in another screenshot it shows that my time spent at 1890 mhz is 40%.... yikes
Has anyone experienced this before? How would I go about fixing this?
Thanks for any help!

Try voltage control, it's what ktoonsez recommends for his kernel and works like a champ for me.

You running old version of sammy kernel ? get newest 8-15b , i to use setcpu and have no such problems , very early versions of his kernel did that.
Post a link to the new kernel...8-11 buikd is fine setcpu and system tuner is the best 2 there is imo
