How do you over clock?

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.

[Q] queation about SetCpu

ok, i searched for the problem i had but couldnt find anything relevant. i hope someone can direct me to it, if there is any already, or give me an answer,
i downloaded Setcpu and ive seen most of people using "conservative" scaling for better battery life, but i dont see that option in the app. i just see ondemand, userspace and performance.
any idea if im doing something wrong?
and also i would appreciate if someone can tell me the settings for longer battery life? wanted to try it but didnt understand that much.
thanks.
btw im using virus rom rc3 with stock kernel.

The governors are kernel specific- if the kernel doesn't support it, it won't show up as an option. In your case, conservative scaling is not supported by the kernel you are using.

oh ok. now i got it. thanks for the info.

Both Netarchy and Kings kernels have "conservative" governors on them. One of the top ways to conserve battery is to make a profile setting for Screen Off where you set the min and max freq to the lowest possible setting. For me though I can go to 128 Mhz, I get too much lag on wake-up and therefore set to 384. Your phone may do better.
Someone also made a thread that describes the advanced settings. Tweaking those can also improve battery life as well.

[Q] cm7 and setcpu update

[Q] cm7 cpu setting or setcpu?
well atm i am running an evo 4g with cm7 and i just switched my kernel to savaged zen and it's running great. my phone was rebooting on its own w/ the regular cm7 kernel i think its b/c i was using setcpu and people are saying it messes up cm7.
so i was wondering if anyone knew if i can use setcpu with cm7 and savaged as the kernel or if it's possible to make profiles on the cpu settings on cm7 i saw some1 post somewhere that you can but they never explained how.
p.s. please also visit this thread on battery life

AFirst of all, all SavagedZen kernels are Havs kernels (as far as I remember, I'll double check in a few). Anyway, if you are using a Havs kernel, changing cpu settings is pointless/counteractive. I would either leave the settings alone or switch to a no-havs kernel. You can check in settings>about phone.
EDIT: However, if you must mess with the settings, you can find them in Cyanogenmod Settings under Performance Settings. I don't know of a way to set profiles from that screen, though - only max/min & governor.

hi i have an evo running cm7 and i had setcpu and my phone kept restarting however i looked up setcpu again in the market and it said that they just ran an update to stop the problem with cm7, does this mean that setcpu is better to use than the cpu setting in cm7?

You shouldn't need setcpu use the cpu setting in cm7. They put it there for a reason, those guys are sharp!

I still use setcpu because I like my screen off profiles etc. You should update your setcpu if it prompted you to. I think the latest changes were for cm7/GB.

I believe the SavageZen governor is a specially tweaked/optimized version of the SmartAss governor.
And if you use Smartass/SavageZen governor, I think it also automatically undervolts when sleeping, and essentially mimics what a screen-off profile in SetCPU would do.

In CM Settings, go to Performance Settings & then CPU settings. Under available governors choose SavagedZen or Smartass. I'd try them out & see which you like the most. I prefer SavagedZen, I seem to get better battery life & performance.

Personally I have never needed a task killer while on CM7, so I am going to recommend against it.

Well I had talked to someone else that is using it like that and they said they get amazing battery life
Sent from my PC36100 using XDA Premium App

I say no toward any kind of task killer. First of all, they're pointless. You're killing stuff that isn't using any power to begin with, which then restarts anyway. The task killer itself is actually doing something, running on a set schedule, where as the tasks you're killing are just sitting in memory for faster opening.
It bugs me that even the techs at Sprint recommend it, so every person that doesn't know anything about how their phone works thinks it's necessary. Then in the market for every clock widget you see everyone going "like zomg the clock doesn't keep time your app sucks 1*" because the damn task killer is killing it. That's if they can even figure out how to use it & not complain that it "won't open", despite clear instructions on how to put a widget on your screen.
Sorry, totally went off on a rant there.
But yeah, stay away from task killers & let Android do its job. You don't have to have a ton of memory free for your phone to run perfectly fine under normal usage. I don't notice a difference between 300mb & 50mb free. If you don't worry about it, you won't either.
Free memory does not equal more battery.

Cpu

Im good on everything else except when it comes the CPU thing. I have no idea what the numbers mean when you set the CPU for some reason. To slow the phones resources when the screen is off right? Can anyone point me to the direction of an app that can do this? What about an app that turns the data off once I turn the screens off. A free one. Thank you and sorry if Im not making sense or sounding dumb

SetCPU can modify the processor speed and allow you to set a profiles. However, you're running Tiamat so if you haven't changed anything your default governor is smartass which has a built in screen off profile of 128min/384max.
As far as turning data off, check out ultimatejuice. There is a free version that is limited in what it does, but it might be worth paying for. Also, for battery saving, check out my EVO link in my sig for some undervolting mods.

You can set the cpu governor with a program called setCPU on the marketplace. You can further control the CPU by flashing another kernel. What ROM are you running? Stock? I would try the netarchy kernel (newest version) if you're running a sense-based ROM.. I've found it has phenomenal battery life (medium use i get 15-20hrs) and I'm overclocked to 1.152ghz.
A program called tasker can also make your data connection go off and back on with the screen. I'm unsure how to set the profile but I do know thats possible. Try looking around here: http://tasker.wikidot.com You should be able to find something about it.
EDIT: Nevermind about netarchy, did not see your signature on your ROM and kernel.

ok, so ur on aosp and tiamat. try changing governer to smartass. will give you much better battery life, and you won't have to worry about 'numbers'.
btw the numbers are the cycles per second, or the speed the cpu works at. i personally underclock to 537 (998 is stock) to save a bunch of battery, and it still runs perfectly fine for me (cm7 with tiamat)

Plus im pretty much sticking with MIUI....I usually use the 25 vipervolting. Now I'm on tiamat v4.0.3. Are you saying sense I'm using tiamat its already set to smartass, so it'll be unnecessary to use the setcpu app? Also I like savZen to what's the default governor on that? Final question, turning the data off when the screen goes off using ultimatejuice unnecessary if I'm running tiamat? Sorry for the bombarding of questions thanks again

Yes, most of the scripts lower by a certain range. So it all depends on the kernel you are running. Some of my scripts (Extreme, Insane, v2 scripts) specify all the voltages so no matter what kernel you're running, it sets the voltages to exact values. If you can go lower than -25 and you're stable, do it!
I find SetCPU unnecessary. I only have it installed because I use it for testing my mods and things, but I that's the only reason. But smartass is good enough for me, no other governors give me as good batter life. Defauly governor on SZ is their own governor (SavagedZen) it's based on interactive, I believe. There is more info on their site.
Tiamat (or any kernel for that matter) don't turn off 3G when the screen is off. You would need an app to do that.

I couldn't agree more. Setting up a basic screen off profile with a conservative setting is useful, otherwise it actually gets in the way of already built in kernel benefits, actually undoing them in many cases. I stopped using setcpu a while ago and my battery life has not suffered at all.

[Q] MIUI Set CPU settings

Whats up guys? I have a question about using the Set CPU app.
Is it really worth it to use this app? Will it actually make an improvement in my battery life?
I don't want to use this app to speed up my phone, but to make it better on battery life.
I know you can set up profiles, but I'm not sure on what good setting would be to use. Can anyone give me some insight on this?
Also I'm running the latest version on MIUI and the Tiamat kernel.
P.S. Is there better kernels to be used then Tiamat?
Thanks in advance.

maybe it's just me, but am getting better bat life with the stock kernal. I ran the tiamat for a few days, switched back and it was obvious to me.

With Tiamat the default governor is smartass, which has a built in setting for when the screen is off, that only lets the phone see a max of 368640, which will save on battery life and does.
Now if you want to get into using your own profiles then an app such as Setcpu can be helpful.
I have been using this and this in place of Setcpu. It's a little faster reacting to the changes form screen off to on. Just another option.
I like the Tiamat Kernels as well as JD's Kernels. They both work well with Miui, at least on my phone anyway.

I've used Set CPU for awhile, but then got away from it. I'm back on it now since MIUI doesn't have a built in OC. I would try the two PacerguyDon suggested. I have used the andrev_oc it is fine. The second one appears to have more functions than Set CPU. Set CPU doesn't allow you to under volt if that is what you are looking for.
I saw that Set CPU is $0.99 on Amazon, if you want it. However, I would try the other two for free and donate to the one you like best.
I have been using JD's Kernel the last few days and it seems to provide better battery life than stock. I originally tried using the Smartass govenor, but had to go back to On Demand. The Smartass was causing screen wake delay when receiving a call.
I stole this from another PacerguyDon's post and it breaks down the different govenors found in most OC apps.
Govenors

Set CPU is free for XDA members. It also does allow undervolting according to their post.
