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.

help needed SETCPU problems

Hey guys im having trouble with my phone when setcpu is running. When ever i come out of lock screen it takes a few seconds to be able to do stuff on my phone, like its waking up from sleep. Also some times i get this message and it has to reboot.
"Sorry activity htc sense (in application HTC Sense) is not responding."
Im running the 2.6.32.15 king # 4 kernel.
My set CPU settings are on 1.15 GHz max and 460800 MHz min. Im running conservative at the moment but it does it on other scaling like performance and on demand. my setting for screen off is 460min 614 max.
Is there anything im doing wrong? or should i be using a different kernel? What kernels are the best? Thanks

I would bump up the lower end to about 600. I have have issues lower than that coming out of sleep.

im running virtuous 2.7
power saving kernel
Main Profile is 245-998 ondemand
Screen Off is 245-384 ondemand
I do not have that problem... but it would be a lie if I told you i didn't before!
I was having this problem you are talking about when my main profile was set to conservative.
EDIT: Back up your setcpu + settings in titanium... Uninstall it (or freeze it) and see if the kernel can run it just fine cause it probably will. Most kernels already have the settings for optimum performance and even the devs who make them (like hydra) say that it will work best without setcpu.
Source: http://www.hydrakernel.net/hydra_kernels_information.htm
"I recommend not using the setcpu controls or governor with these kernels. Let the stock governor do the work. If you have setcpu installed I recommend clearing out the settings before flashing the kernels. You can use it to monitor cpu speeds or an app from the market called systempanel if so desired."

Need a little help

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

Sense Kernel with Mikfroyo 4.5

Hey guys,
I'm about to update from 4.4 Mikfroyo to 4.5 and I was looking to get suggestions of what Netarchy kernel to use. I currently have 4.3.1-cfs-havs-nosbc installed. Should I go with a sbc? Also, are you guys using setcpu to set the peramiters or does the kernel do it on its own? If you need to use setcpu, what settings and profiles do I need to set. I am currently set using setcpu at 1190 MHz max and 245 Mhz Min. Scaling is set to ondemand. Thank you all for any help

how are you updating i have 4.4 also, do you just flash over current setup without wiping anything.

Don't believe all the hype....
I've been using sbc since beta and I've had no problems/overcharging
+ you get an additional 10% battery, based on usually when you pick up your phone (without sbc)drops down to 90% pretty fast
Swyped from a galaxy far far away......

Which one do you use? Do you use Setcpu and what settings to you do? Thank you

[Noob Guide] What is and How to Undervolt

Hello, i wanna share my experience undervolting.
For people who dont know what undervolting is, its the power or energy that the battery send to the CPU with determinate clock speed.
For example:
384 Mhz is the lowest frequency of our CPU, it has a 800mv volt in the stock ROM with stock kernel.
So in theory, the battery send 800mv to the CPU when it runs at 384 Mhz.
The effect of undervolt the CPU is bassically get more battery life and at the same time reduce the temperature of the phone.Less energy send less battery used and less hot phone in our hands.
How to Undervolt
Im running Stock ROM with Ruby Kernel stable.
For undervolt you need a kernel that support it, you can do it in all rom if the kernel support that.
If you want to Undervolt, i recommend you to use Trickster MOD.
You can Undervolt maybe -50mv all frequencies and see how it goes. Some people can even in best cases undervolt -200 mv. But you need patience to test slowly.
DONT TICK SET AT BOOT IF NOT TESTED.
That why you cant:
For example if you undervolt -100mv and if not stable, and you have set at boot ticked, it will freeze the screen and after reboot it will happen again.
After you set the mv for undervolt, download from play store CPU stability test and run it.
It will test all CPU frequencies to see if it is stable.
If you dont get any SoD, congratulations its stable.
My undervolt settings are -100 or in some cases -75 mv and very stable. My battery temp is 30 C°.

Thank you very much

What is needed to undervolt?

Thanks for the info. What are your battery stats after undervolting? How does it suffer other operations of our mobile like browsing or gaming etc ?
Sent from my LG-E975 using xda app-developers app

You need to first make a backup, install a custom kernel, install trickster mod, and from there apply what this discussion is talking about. Good luck!

Bootloader unlocked with freegee and some kernel for your rom that supports undervolt.

Depends on the kernel. I am using Trickster Mod with Viper ZVC kernel. There are other control apps available -- some of them are kernel-specific, some are more universal (Kernel Tuner, Android Tuner, System Tuner, etc.). Look in your kernel's thread -- the developer usually tells which control app(s) to use with it.

Thank you, I'm using AK kernel with UKM and Synapse app from google playstore. Using E-975 (intl.). Can you suggest if I should change the global setting or the individual settings for frequencies ? I had recently (soft) bricked my phone by running benchmark at ~1900mhz CPU and 487mhz GPU (like a villain, I know. Re-connected battery to save it... phew..). I'm really cautious now and I just want it to be less hot and save some battery, that's all. Any guidance would be really appreciated... thanks
