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.

Installed kernel, now buggy sound on video.

Hi guys,
I'm a bit of a noob so please bear with me. I recently rooted my phone (SGH-I747M Telus), I have CWM recovery installed. I was interested in overclocking so I installed this kernel on my stock rooted rom (I installed the "sammy" one). I also cleared the delvik cache, cache, and fixed permissions before rebooting. Now I'm having a weird problem with video playback. I get these bleep like sounds, like you might hear on a spaceship, lol. The normal audio plays in addition to these sounds. Yet, regular audio plays fine (mp3s), same with youtube. So, my question is, why? Is there any way of fixing this? I'd rather not play around the stock ROM. I made a backup before doing anything and recently tried to restore the boot, but I got an invalid md5 check.
-JC

Okay, I was able to fix my problem by flashing the stock at&t kernel... but I would still like to be able to overclock... is there another kernel that I can try or a way to fix the problem with the kernel I already tried? Thanks.

If you still want to try previous kernel your problem might be because of heavy undervolting , kernel creator posted this voltage chart.
You can experiment by increasing voltage and see if that helps.
Or you can just try this faux kernel , its pretty good also, we don't have many kernel choices for Samsung based roms at this early development cycle.

Thanks for the reply... but I was able to fix the problem. It was something wrong with the settings of SetCPU which I installed earlier. I changed it from on demand to performance and now all is well. Now I have a question about battery life. Will overclocking drain battery a lot faster? I imagine it would only make a difference if I was doing CPU intensive things.

Well.. performance setting makes it so that your CPU runs 100% all the time. I don't think that will be battery friendly . Overclock generally uses more power and battery longevity will depend on your usage.
You can try messing with setcpu settings. Try Conservative, then limit minimum speed to 384 and max to your preference. Try your movie again.
Current kernels and setcpu are a bit quirky.

I had the same issues on ktoonsez Sammy. Ended up back at stock AT&T. I've heard it's an issue with many of the kernels but a fix is on the way. Couldn't find a way to get rid of it, but that's not to say it can't be done. Don't have much time to tinker right now.

Its a known issue on ktoonsez kernel. Flash faux's kernel, it has the same features (as well as GPU OC) and doesn't have the audio issue.

Performance and Kernel trouble

Hy all,
I'm running JB Sourcery V5.1 (latest) and I had some trouble wih the speed.
The ROM comes with it's own kernel, it allows me to overclock my GNex to 1.4 GHz top (screen attached).
I ran a Benchmark and poor results. See from the screen, the results are lower than what a Gnex should be !
I tried to flash Franco Kernel but the device won't reboot, it stays on "Google" and never starts the bootanimation (i had to do a wipe to make it boot).
So if you are on JBSourcery, is there a way to overclock it more than 1.4 GHz ?
Why does the Franco Kernel block the boot ?
Not every Kernel can be flashed on every ROM ?
Thanks for the answers like always !

I managed to make the franco kernel work.
There's a section in the JBSourcery tools dedicated to kernels. This ROM is amazing really.
Anyway, thanks i guess ^^

As you can see in the Quadrant screenshot, the I/O Performance probably is the problem. Wich I/O scheduler do you use?

I'll check the scheduler settings.

Hy,
The settings are :
Read ahead buffer size : 1024
Scheduler : deadline
I never touched these so I don't really know what there here for ...

You base your performance based on a number spit out from Quadrant...
Here's a novel thought: How does it actually work for you? Are you having problems with it lagging during certain operations?

Yea, Cilrazz is right. If your system is smooth you shouldn't care about the Quadrant results at all.
To answer your other questions:
a) You can not use every Kernel with every ROM, there migth be some incompatibilities.
b) If you want to overclock more than 1.4GHz, you'll need another ROM, wich allows that. But you probably won't need that for smoothness or performance during standard use. In fact a lot of people have underclocked their CPU's to 10.6GHz and the GNex is still more than fast enough for everyday use, while saving a lot of battery with this lower voltage.
c) concerning the I/O sheduler. wich schedulers do you have available, maybe another than deadline does work better for you (personaly 'fiops' works best for me) ...ah and I'm pretty sure, you should set the read ahead buffer size to aprox. 2048 for better performance.
d) I don't know whats your exact problem with the franco Kernel. Have you tried a clean flash? (means: wipe cache+dalvik, factory reset, format system, install ROM, kernel, GApps, wipe cache+dalvik) -- ! make a backup first, you will loose your settings, when resetting to factory and loose your app and app data on format system !
Ah and i'm pretty new here too, so be carefull not everything i'm saying is 100% right. :fingers-crossed:

The benchmark results were only here to show the lack of speed that i had. But i really had speed trouble and i couldnt screen that ^^
But now it's all good. Thanks for the answer tho'

Hey,
Thanks for the big answer mate.
I'll try to answer step by step
B/ I did manage to flash the Franco kernel but using the download kernel feature in the settings (maybe a special version). The over clocking is for the gaming actually like Modern Combat, but the device becomes hot as the sun ! (Not good).
C/ I never touched the I/O zone. It works pretty fine this way so I won't mess with that ^^
Thanks for the answer tho'. Very much appreciated!

How to make phone snappier?

Hi all,
I've been running DKstunna's CM9 global rom with aeroeven's v14 kernel for a few weeks now. It's a great stable ICS rom that makes for a great daily driver.
My question is if anyone has tips to make the phone snappier. For example, if I hit the search button, it takes a full 4 or 5 seconds before google now comes up. Another example, if I'm installing an app, there is significant slowdown all over the place.
I know I'm working with a phone a few generations old, but does anyone have tips to make the phone snappier? I'm open to everything, including flashing new roms, new kernels, etc. All I'd be wary of is flashing roms that would decrease phone stability.
BTW I did a search! but didn't see anything.

You probably didn't know what to search for...hence the results. You need to look for overclocking, cpu governors, minfree settings, zip align, and there are others that speed up your phone.
First: under performance settings, what max cpu frequency do you have it checked as? And what governor are you using - I personally like smartassv2.
Second: try a different kernel if you have already overclocked and set the governor.
Third: try a script like v6 supercharger. There are a lot of them that take care of some of the above mentioned stuff for you.

Thanks for all this! You are correct, I clearly had no idea what to look for.
My min cpu frequency is 245 mhz, max is 1024 mhz. The governor is smartassv2 - it must have flashed along with another rom/kernel I may have tried in the past.

[Q] phone crashing

Need help or advice , last week i've been using lollipop rom, im not familiar to the new settings and setups on this so i explore and try the kernel settings. I set my kernel setting to maximum, like cpu which is about 1750 mhz all cores and gpu 450 thermal off etc. Because i hve been seen some comment that the lollipop rom reaches to about 27000 k antutu score . i tried it by my settings which is my phone crashed while testing it to about 25% of testing. Now i just go back to sling rom and try again to test with no modification with the kernel or any optimizing the performance and im surprise that it crashed too and tested with putting my phone on the freezer which i guess im having phone temperature problem but it crashed too. Now while charging and testing in the same time it completes the benchmarking of my phone.
I guess my battery is the reason my phone is crashing when on the heavy load of using
Or some hardware issues? Like cpu,gpu ??
Sorryto my bad english and explanation. Thanks

See this thread and check you PVS value of CPU....
http://forum.xda-developers.com/nexus-4/general/poll-cpu-binning-t2052496
If you are getting slower or slow PVS, try to increase the voltage of 1750mhz freq and run the benchmark...
Hope it helps

Thank you . the result of my PVS is 4. I also suspect that i have low voltage to run the processor thats why when im doing benchmark it shutdown even playing COC.
How can i change my voltage and what is the default voltage ? Thank you again.
