Can some one help with guide on how to overclock. What are the difference schedulers and what does they mean? Also someone can share their PMC Volt setup so I can have a starting reference.
TIA
You can't overclock your CPU until you flash a custom oc kernel on your phone. You have to look in the dev section for those of course. From there on you can use apps like SetCPU or Antutu to overclock your CPU.
Hope this helped

I have flashed MIUI with SwiftExtreme-loc kernel. I want to know how to do the overclocking? I was looking for an example to set voltage and scheduler
Allright in that case try to install the app called Antutu CPU master. With this, you can overclock your CPU. I'm not really sure whether swiftextreme supports governor changing because I'm using IronKernel myself. But if it does then you should be able to change it with Antutu as well. By the way if Antutu doesn't work you can always use SetCPU.
For undervolting you can use the same app but I can't tell you how much you can undervolt because that's different for every device, rom, kernel etc. The best tip I can give you is to try to uv at each frequency and test whether it remains stable.
Note that our devices can't handle any voltages below 770mv.

All above is correct.
Governors aren't useful on your kernels forget about them.
Schedulers are used for read/write operations on sdcard.
Bfq, deadline, anticipatory, cfq, are some of them. They determine the way the kernel will organize the packets of data before reading or writing them.
Anticipatory is mainly efficient with file systems having a journalization feature, that means ext3, ext4, but not vfat or ext2.
Three two preferred seem to be bfq and deadline.
For more details Wikipedia is your friend.
Hello!
Here is a god summary of Linux/Android schedulers...
http://forum.xda-developers.com/showthread.php?p=20895475
For more details you should look into the kernel threads.
You could either go with the preset of your kernel or try setting up your own OV/UV-table using pimp my cpu or set cpu…
…but in case of the SwiftExtremeKernel you could break more than you achieve. If you want to go with this kernel – just leave it as is, because it is already optimized for longer battery life and OC in case it is needed…
If you want more performance you should look into ironkrnL because it is more optimized for responsiveness and faster kick-in of the second core – vodonka did a hybrid of SwiftExtreme and ironkrnL – you could try it.
…just follow the ironkrnL-threat.

GingerDX V19..
in cpu setting > available governors.....what this is ??
smartass.
conservative.
ondemand.
userspace.
powersave.
performance.
This are the features? let your battery faster? I could spend the description of all? and which option makes the ROM faster?
smartass
Based on interactive, but better.
conservative
Available in some kernels. It is similar to the ondemand governor, but will scale the CPU up more gradually to better fit demand. Conservative provides a less responsive experience than ondemand, but can save battery.
ondemand
Available in most kernels, and the default governor in most kernels. When the CPU load reaches a certain point (see "up threshold" in Advanced Settings), ondemand will rapidly scale the CPU up to meet demand, then gradually scale the CPU down when it isn't needed.
userspace
A method for controlling the CPU speed that isn't currently used by SetCPU. For best results, do not use the userspace governor.
powersave
Available in some kernels. It will keep the CPU running at the "min" set value at all times.
performance
Available in most kernels. It will keep the CPU running at the "max" set value at all times. This is a bit more efficient than simply setting "max" and "min" to the same value and using ondemand because the system will not waste resources scanning for the CPU load. This governor is recommended for stable benchmarking.
Don't set governor to performance just because it's "performance". It will not increase your phone's speed in any way. Better use ondemand. For performance, I suggest ondemand. For battery smartass.
Smartass is based on ondemand governor but better and not on interactive
I got reboot when I enable smartass on gingerDX, any sugession?

Few solutions
- u must not exceed the overclock limit (710 Mhz). So, change it or dint use oc
-everytime it reboots,just enter xrecovery and clear cache and dalvik cache

LDX has known problems with smartass. the only workaround is to either flash stock kernel and revert or u need to do a fullwipe
Hey does someone know the overclock configuration that was posted on the Overcome page once? I'm running on Overcome 4.1 with the belonging Kernel which allows me to get to 1.6ghz (theoretically) and I'd like to overclock to 1.2ghz.
I'd be very grateful if you could help me
Edit: I found this http://forum.xda-developers.com/showthread.php?t=1036020 but does this guide also apply to Overcome 4.1?
Just use Voltage Control or SetCPU. It's really not that hard at all. Just be careful with your voltages-overvolting will eat your battery more but may allow you to reach higher frequencies, and undervolting may get you better battery life but may make your tab unstable.
As a reference, I have my Tab running at 100-1.4 with smartassv2 and stock voltages on the Overcome 4.0 kernel.

thanks ;-) but which sheduler do you use?
for those who also have problems with overclocking and for
the newbies (like me =-D) I found this page which describes the usage of shedulers
and governors http://forum.xda-developers.com/showthread.php?p=19846297
IO Scheduler: CFQ
Governor: Smartassv2
At least that's what I use on my phone. I just left everything alone on my tab.
Sent from my SCH-I510 using xda premium
thanks, you helped me a lot ;-)
I'm using Voltage Control on 1.3ghz with stock voltages on smartassv2 and deadline and it runs pretty stable
Thanks, useful tip for me too.
I use SetCPU
OC max 1.3GHz, min 100MHz
-75mV from 100Mhz --> 1.0GHz and then -50 from 1.0GHz to 1.3GHz
PLUS various profiles to set max to 800MHz whilst screen off etc etc
that's exactly the same that I did =-D=-D=-D
That's pretty much what I have. OP, sorry I couldn't answer your PM, my tab is currently bricked and I haven't had the chance to recover it.

yea I have time =-D that's not so important, just make sure your tab runs again ;-)

This is what worked for me as well, just don't check"set at boot" option till you've tried that speed for a few days and you config proves stable.

Haha, I did check that option when I foolishly set the OC max to 1.6GHz
...I was just able to uninstall between one of the many lopping reboots
Anyway all, sorted now. In fact I have reverted to stock voltage for 1GHz up to 1.3GHz because playing Trial Xtreme2 would cause a reboot when I'd exited the game - seem's all ok now *touches wood*
I'm using emanoN V4 with No-Frills, and since CM7.1 with SetCPU, I always used 'ondemand' as Governor.
But reading other posts on other devices forums about this, some people say SmartassV2 is the best...
So, as each device is different (specially by the ARM version and manufacturer), I decided to begin this conversation here, and listen to what people with the same device as me has to say about it.
So which Governor do you consider the best for SGM?
Im using cm7.2, setting at nofrilis Governor : SavagedZen io : sio and undervolt at cm setting, give more battery life.
Sory for bad english

Thanks for the reply, but as I can see on No-Frills, sio is th I/O Scheduler, that is already set. I'm asking here about the Governor.
Ondemand and set noop
Sent from my GT-S5570 using xda premium
on emanonV4 i use Smartassv2 nd i/o noop
I see that people are very divided between ondemand and SmartassV2.
Now with sio and noop as I/O Scheduler.
Anyone else would like to share?
i will say ondemand because cpu will be set at lowest frequency and when you need it it will set at higher frquency which will save your battery and if you want performance then no lag will be good
The principle of the ondemand governor I'd already figured out (and actually didn't like it, very rough).
I would like to hear more about the principle of the SmartassV2, whereas since this morning I'm using SmartassV2 + noop and I noticed my SGM way smoother than with ondemand + sio.
Now is wait and see if the battery is sucked more.

smartassV2 is a re-working of the original smartass governor, it allows for the CPU to scale through all frequencies from the lowest you set to the highest, based on the load occuring. Basically it scales CPU based on realtime needs of the system, saV2 supposedly incorporates some more agressive settings for screen off, and I believe quicker scaling than the original smartass.

Thanks a lot, man! And now I think that I had made my choice:
Governor: SmartassV2
I/O Scheduler: noop
Highly recommended!
Which is the best gaming kernel and rom
.....????
Sent from my GT-N7000 using xda app-developers app
Best gaming kernel ?
The latest AniDroid kernel.
Underclock it to 250MHz @850mV.
Overclock it to 1.6GHz @1300mV.
Undervolt each frequency.
Overclock the GPU to 400MHz.
Install ChainFire Engine from the Market.
The ROM doesn't matter much, but I'd stay clear from TouchWizz because its bloated.
Something like sixstrings's AOKP Build 40. Or ParanoidAndroid v0.5. Or some other ROM.
The most efficient IO is Simple IO governor, aka SIO. Benchmarks show it as weak, but its actually the best one, eveyone knows this.
The most efficient governor for the N7000 is interactiveX.
lulzactiv and pegasusQ don't seem to work well for many people (me included).
When gaming something intensive (GTA3, DeadTrigger, Flash games, etc) you might one to change it to "Performance" governor. But it will drain your battery fast, so have it charging or have a spare battery handy. And remember to deactive "Performance" governor back to interactiveX (or otherwise Hotplug or Ondemand).
Besides this, try experimenting with different set ups. You could get different results, and find what works best for you.
OK. THREAD CAN NOW BE CLOSED. DON'T FORGET THE THANKS BUTTON.
how i configure CastagnaKernel OV for have max performance without trasform in cheese my cpu? what the governor? the i/o scheduler and the processor mhz?
Sorry for my bad english,but i am an ignorant
OV? Over-volt? do you mean OC? Overclock or UV? Undervolt
smartassV2/SIO (personal favourites)
245mhz/1800mhz (so default settings)
And I think you can better post this in the topic itself, and you will never turn your cpu into cheese, i once ran a benchmark at 2.016Ghz, and it just turned off

I remembered the cranium kernel at 2016 mhz..it became really hot...
Ondemand( little bit tweaked) 368 1804 sio...that s perfect
Q.D.E.
It would be better if you post this on kernel's thread I think there is no need to made a new post about that and sorry but and I'm not trying to be disrespectful. however you can use smartassv2 245-1800mhz that's a good choice.
Sent from my GT-I9001 using xda premium
the combination of default: lulzactive + sio is very performant (CFS version)
or you can try the governor lagfree
if you want the best reactivity using the BFS kernel version,
but is less multitasking
