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] Manually set clock speed?

I've used SetCPU in the past and have determined that my max stable clock speed is 113600; I've also read that using SetCPU to control clock speed can create some problems.
How would one go about manually overclocking the phone without using SetCPU? I was looking around in /sys/devices/system/cpu/cpu0/cpufreq and it looks like there are kernel settings there, just want to make sure I don't bork anything in the process
Thanks in advance!

From my understanding is that if you get an overclock kernel it will basically run in the same fashion as your current kernel (as far as governing speed goes) except you'll have a higher max frequency.

SetCPU is the GUI to do what you are talking about... Are you looking to go past 1.113? I can only get to 1.113, but if I run Hyrda's OCOV kernel I can get to 1.15.
I would say if you don't know what you are doing, I wouldn't mess with it. Nandroid is handy if you do.

I'm running invisiblek's #16 kernel but max clock speed is showing 998. Not trying to go over 1.13 but thought I read somewhere about being able to manually change it in the system files somewhere without using SetCPU.
IIRC the idea was to use SetCPU to determine your max stable clock speed, then change it manually in a system file somewhere and then not use SetCPU.

Try uninstalling/reinstalling setCPU. I've had issues every once in a while when flashing a new ROM, then doing the app only restore from a TI backup cause issues.

Personally I can't say I've ever had any problems using SetCPU, but if there's a way to make it default to 1.13 without having another process running then I am all for it, thus my question. Just don't know where to change it

I can tell you i am 99.9% sure that you were right with the file location in your first post.
If you check chads thread SOMEWHERE in there i think its mentioned... Sorry to say but i have no idea where.

Here's a script that Ziggy wrote, you can edit it to your needs and flash it and fix permissions. Without editing it's set at 1.113GHz Interactive screen on and .384GHz Ondemand screen off if I remember correctly. It also has another tweak (memory management I believe?). But hey, it's a start.

Much appreciated guys, I will check out Chad's thread again and look at that script. I just don't see the need for SetCPU if I can just plug in my known stable values and roll it like that Thanks again!

Fixed lol sorry

LOL Blah! :-D

I have tried editing those files and it does not seem to change the clock speed. Anyone who has successfully done it manually could you please list all the specific files. Also im going to examine the script that was linked and see if i can tweak it a bit. Ill post any findings here.

I use the custom kernel #18 and setcpu, clocked to 1.115 easily with cm6.1. works awesome and smokin fast.

I edited Ziggy's script using EditPad lite (free, just Google it) since I'm on Windows so as not to change the format. Flashed from recovery then fixed permission in Root Explorer. Worked like a charm.

[HELP PLEASE] Need assistance for Battery performance with collins tweak

Ok,i have a lot of questions.
And i really am in need of AWESOME BATTERY LIFE.
I was told that collins tweak runs the best,so i tried it out with RefinedEvo 1.2
it was AWESOME in 3 hours i got to 90% with Netarchy's 4.1.9 CFS Nohavs.
i just flashed the collins tweak over it the Rom and it worked.
It was the best battery life,I ever had but now i cant get it back.
everytime i flash it from another rom or some sort it wont give me the same results.
i didnt touch the collins tweak until now,since im trying to put it on RefinedEvo again or Myns Rom.
But i dont really know how to properly use it. the GUIDE TAUGHT ME NOTHING.
i mean i dont see KSOFT ANYWHERE. and i dont even know what it means. but i see it in others screen shots but i cant find it in my own phone on terminal emulator. what do i do? do i run it as root? do i run it t 1152mhz or 998mhz? i know i should be running it at 998mhz to get better battery life,right?
but i am and i see no change? and i try to customize but it doesnt really help,i dont wanna funk with it. what governor should i keep it on smartass is the best right? but i heard it doesnt play nice with it.
PLEASE SOMEONE OFFER ME ASSISTANCE.
like how to properly do it?
and if i flash another kernel on the rom what do i wipe? everything like dalvik cache,cache,and data/factory reset? what do i need to do?
do i have to do any battery mods? like unplug when its green then plug it when its blank and what not?
what can i do? PLEASEE. i've TRIED ALMOST EVERYTHING. NOTHING WILL GIVE ME GREAT RESULTS!
i mean i use SetCPU and that was BEAST.
but i hear collins tweak is much better.
help me,please!
sorry,for really spamming this crap.
but i really need help and nobody would help.
i mean i bet you guys all needed help one time or another.
I need to know-
how to flash something properly without ruining anything.
how to properly run collins tweak
how to get the best battery life i can
what kernels would run best with the Tweak on Myns Rom.
RLS3 or 4?
maybe setcpu profiles?
BASICALLY,What Kernel do i use to get the best battery performace on Myns rom RLS4 or RefinedEVO 1.2
to run smooth and quick enough but can last me a best battery i can get with the Tweak flashed over it.
PS.I WILL DONATE TO ANYONE THAT CAN GIVE ME VERY BEST DESCRIPTIVE INSTRUCTIONS,REAL HELP, WITH ALL THE NEEDS FOR MY BEST BATTERY LIFE.

Ok i will try to do my best helping you. I will warn you i am not a pro on collins but have used it and feel i have a simi decent understanding.
First it is my understanding the rom you are using has to "support it" reading the post myn made about ti tells the other rom devs what they need to do to support it. Obviously myn's rom (post rls2) supports the tweak however i am not sure about RefinedEvo as i dont have experience with it.
First "how to flash something properly without ruining anything"
This depends on what you are flashing. If it is a new rom i always suggest wiping data/factory, cache, and dalvik and most will recommend wiping cache and dalvik twice to be safe.
For a kernel, theme, and most tweaks it is not necessary to wipe the data. It is a good practice to wipe cache and dalvik before you flash anything (as well as make a nand back up of course)
if you follow this you shouldn't screw up anything.
second "how to properly run collins tweak"
For myn's the way i would set it up is to
1) flash myns (with wiping etc) boot it up.
2) go back to recovery and then flash your kernel and any theme you want then boot up again fully
3)go back to recovery and flash the collins tweak.
if you flash collins tweak before the kernel is when you seem to have the highest chance of problems.
For myns collins is set and ready to go after this to my understanding with the default options. I find the default options are fine for my personal use. It is possible i could tweak it more to squeeze out a little more life but havent found it necessary.
third"how to get the best battery life i can"
for me the best battery life i have been able to get on any given rom is using collins and ultimate juice to turn off mobile data when my screen is off. This is a tricky subject because i see different posts all the time of people bragging about "63 hours" of time on there phone. if you look at their screen shots it is easy to see why. they didnt use there phone at all. if you see someone bragging about there charge time and android system is 2%, and dialer isnt on the list i would ignore anything they have to say. The normal time for people who use there phone is about 16 hours of life or less depending on how heavily they use it. The only reason i bring this up is to make sure you have realistic goals. Obviously if you dont use your phone much at all you can go longer.
forth "what kernels would run best with the Tweak on Myns Rom."
I personally use netarchy no havs. DO NOT use a smartass (with havs) kernel with collins. they cause issues and you will normally get worse battery life. you can also use the stock htc kernel if you prefer
Fifth "RLS3 or 4?"
its up to you but i normally suggest at least trying the latest version of roms before downgrading. I have had no problems so far with rls4
last " maybe setcpu profiles?"
no you do not want to use setcpu and collins. To give an understanding why. Basically HAVS set cpu profiles and collins all do a similar function. they scale your cpu speed depending on how it is set up. having a mix of these causes issues because one may say the cpu should be at 500mhz and another may come along and say 900mhz and then it overrides the previous setting where the first one then tries to set it back to 500. additionally how they determine it on demand, conservative etc can be different so they end up fighting with each other. this can cause additional battery drain and negates the effects of the tweaks.
in my opinion the best you can do is to flash mun rls 4 with netarchy kernel no havs (cfs) and then the collins tweak flashed over it. If you want additional life you can try juice defender/ultimate defender as well if there are times when your phone screen is off for decent chunks of time.

Wow thank you.
That really helped.
But I knew alot of those things just recently.I actually need help finding out what kernel to use I know netarchy nohavs CFS but which one 4.2.1 or 4.1.9? That's my problem.
can I use the htc kernel# 17 with the tweak or no?
I know not to use Setcpu with collins tweak.
But really,I can't use a havs kernel like CFS more aggressive by netarchy and collins tweak? It will give me bad battery life?!
I don't know what to do, should I use Setcpu or collins tweak?
What rom and what exact kernel tho?
For the tweak what governor should I use?
I mean I know when you use Setcpu you use smartass governor because it runs best right?
Can I get some help on that please?
well does RLS 4 run great with collins tweak? Will kings BFS or CFS# 9 work great with the tweak? I want optimal battery life. I once had 30 hrs with very very very heavy use.
Btw I want to customize the settings on the tweak what do I use?
What's ksoft?
How do I know if the tweak is working properly?
And if I can improve it.
But overall that was great. Your the only one to respond.
Id gladly donate,please some more help would be great.

[Q] AOSP, Kernals, and a Newbie.

I am fairly new to this scene.
I recently got an EVO and decided I hated Sense so I went looking for a stock ROM. Light and fast. I have tried Cyanogenmod7 and Salvage Mod. The thing is, the battery life I am getting with these ROMs is awful. Cyanogen I was losing 20% an hour with the screen off, the phone untouched. Salvage Mod, I am down to 85% in an hour and a half.
I have read about kernals and how they can help with battery life, speed up performance, etc. What are some that I should look into using and how do I go about applying them? Is there a failsafe if its a bad flash?
Also since Sense feels so slow and bloated (to me at least) what are some other good AOSP ROM's out there? That have a little more to it but is not loaded down with unnecessary tools I will never use.

Personally I run:
rom: CM7 Nightlies
Kernel: Tiamat 4.0.6 [3.3.7 is the GOD of battery life]
Mods: Viper mod, undervolted at 825mv floor and -100mv
CPU: Under clocked at 128 min and 537 max
Many people use my setup now and get great results, so I would recommend it to you.

Doesnt the nightly ROM tend to have more issues or do they run better than the stable builds?
What are the Mods? Viper, and then what does it mean undervolted at 825mv floor and -100mv?
Thanks for the help thus far!

mods = modification type tools
viperMOD is a mod put out by viperboy. it allows you to undervolt your kernel.
less voltage should translate to less battery consumption. take your time and read the post, it may look intimidating but it's rather simple. NOTE: if you lower your voltage too much your EVO will get stuck at the boot screen during the next reboot. do not fear...simply go into recovery and reflash your nightly this will reset your voltages. i'd suggest lowering the voltage in increments of 25 or 50 till it hangs then raise it by 25. run with that for a few days to see how it feels.
you may want to look at the Supercharger script (see signature), its not a battery saving mod, its more for memory management and system responsiveness. again, the OP looks intimidating but a reflash will reset your system. (ie: you will have to rerun both ViperMOD and SuperCharger each time you flash a new nightly)
nightly's may or may not be more stable than the RC. it all depends on what was added the day before. the easiest way to find a good nightly is to scan thru the nightly thread for a nightly that is a day or two old...if it causes issues folks will cry and moan in that thread...once you get a nightly that works well for you i'd suggest you stick with it until the link below indicates a new feature or fix that you need/want.
this page will list the EVO related changes included in the latest nightly
http://cm-nightlies.appspot.com/?device=supersonic
see signature links to viper, super and nightly threads.
have fun.

Salvage is awesome. Extremely light and plays well with V6 Scripts. Try them all out, give them a least a couple of days each.

How long does it take for the battery life to stabilize? Its looking like Salvage is averaging out to about 10% an hour, but I know I could do a whole lot better than that.
Any other Mods, kernals, or ROMs (especially AOSP) you guys would recommend?

After flashing a rom, charge the phone up to 100%, then go into recovery and wipe the battery stats; you'll see the change in roughly 2-3 days, as it has to 'settle' in.

note: there is a difference between a SBC and nonSBC kernel. this has to do with charging the battery. there are some folks that do like/trust SBC and others (myself included) that appreciate SBC. basically, SBC pretty much ensures that if you plug in your phone at night before you sleep when you take it off the charger in the morning you will have 100% battery to work with. Stock (or nonSBC kernels) will charge to 100% then stop charging and drain to 90% then charge to 100% rinse repeat. this means that when you take it off the charger you will have somewhere between 90-100% charge.
also, keep note of which applications are sync'ing and at what interval.
for example: do you need facebook to sync each hour? do you need weather to sync each hour? etc.

Also you might want to try SavagedZen RC4 and/or its kernels. They have built in HAVS (like Vipermod) and on the fly SBC (you can just uncheck and check it off)..

Jakister, do you have a link to that ROM? Reading up on it, it sounds awesome. I followed the main thread and the link to download it is dead
Nevermind, it must have just been down when I tried to DL it.

Try this one: http://mirror.savaged-zen.com/ forgot abt that dead link..happened to me when u try it from "mirror" instead from "download now" link. Works?

That one worked! I have flashed the Tiamat (sp?) kernal and the battery life was great for awhile but then it started to dive again. Also, the GPS could never grab ahold on the Cyogen mod. One of these days I will get it right!
Any other AOSP kernals you guys would recommend me look into? I also have the smartass governor on and have my CPU marked to go from 245-729. Do I need to make that lower? I figured 729 was a good compromise from 998
Any other AOSP Roms you guys would recommend?
I have looked at
Salvage Mod
Savaged Zen
Cyanogen Mod
Are there any other ones worth looking into? I think I need to figure out undervolting or find a better kernal

My Configuration
Savaged-Zen kernels have a new download server which can be found here: http://sz.munkibizness.com/ I personally use MIUI with a Savaged-Zen kernel along with viperMOD and Supercharger V6 for speed and simplicity.

How do Vipermod and Supercharger work exactly? You change the settings for those in the Terminal?

Yes, you change the settings for them in the Terminal. However, for vipermod, I use Terminal Emulator (available free in the Market) and for Supercharger V6 I use Script Manager (available free in Market also) and BusyBox Installer (in Market). For BusyBox Installer, make sure you have 1.18.2 or lower installed from within the app.

[Q] Is it better to run scripts or programs?

I have been doing some research and I am getting all sorts of confused now. What is easier on the battery/os/basically everything? Would it be more effecient to run scripts like V6, or to run programs as in Car-o-Dopes tutorial? I am just looking for something that takes the stress off of the os and battery, thus having a faster system and better/longer battery life. Right now I am running CM 7.1, Tiamat SBC 4.1, Vipermod -75 (I think), V6 script with 3G optimizer, along with SetCPU profiles. Any insite/ideas will be helpful.
