You can set the maximum frequency to 1100 mhz and the minimum to 200 Mhz

Hi Funky Pear. In the Governor tab there are several entries. What settings should I enter for all those entries? And in cfq, what value do I choose?

There could be many governors depenting on kernel.
Can you tell me which governors are available??

If you want general reaponsiveness set row instead of cfq. And bfq is better for multitasking.

Row?? What do you mean? There are only 3 options which are: noop, deadline and cfq.
Ok,then use deadline instead of cfq

Deadline:
Goal is to minimize I/O latency or starvation of a request. The same is achieved by round robin policy to be fair among multiple I/O requests. Five queues are aggressively used to reorder incoming requests.
Advantages:
Nearly a real time scheduler.
Excels in reducing latency of any given single I/O.
Best scheduler for database access and queries.
Bandwidth requirement of a process - what percentage of CPU it needs, is easily calculated.
Like noop, a good scheduler for solid state/flash drives.
Disadvantages:
When system is overloaded, set of processes that may miss deadline is largely unpredictable.

Does anyone ever change the min. clock speed?
Well I don't
you don't have to change the minimum frequencies.
i change my maximum clock at 1497MHz & keep my minimum at 245MHz.
try to use Titanium-KISS kernel from Maxwen, dude

I would but I'm on CDMA.
Can someone explain what the schedulers do? I understand the base meaning but I'm wondering what to choose for what?
noop?
deadline?
cfq?
sio?

excuse me; have question about this kernel; i couldn't post in the original thread;
by setting the min clock speed to 768MHZ & the max to 1407MHZ, How much voltage does it spend? by setting the min to 245MHZ & max to 1024MHZ how much? i overclocked to 1407MHZ , i saw more smoothness and speed; but i felt that its consuming more power!
is overclocking harmful to CPU? ( always overclocking )
Rom: MY One V RC4.0 FX

Hi
Political correct answer:
Of course OC "can" harm your device - like all OC´ing
Realistic answer:
Most One V devices can handle OCing up to 1.5 without problems
but since this may be specific to chip manifacturing there is no
guarantee that it is. Therefore before using any OC you should
test it very carefully.
And also - Of course running the chip at higher frequencies needs
more power. Simply physics .)
In "normal" daily use the difference is not big because the cpu will
not run at high frequencies most of the time. If you do things
like "heavy" gaming this is of course forcing the cpu to run faster.
To reduce the "effect" a little bit there is a kernel feature called
Undervolting (UV) with that you can reduce the voltage for
specific frequencies. Like OC this is device specific. So some
devices can run stable with more reduced voltage then others
BTW: why to you set the min frequency to 768?
This will limit that the frequency cannot go lower then that if the
device is idle. Running at 245 needs of course less power then 768
max
Thanks for the nice info, well, i heard that some users said that the best frequency for " My One V" rom:
Minimum: 768MHZ
MAX: 1407
I'm using "Set CPU" to OC
So setting the min frequency to 245MHZ will save more power, right?

Yes - especially for the time before the device can go into
"deep sleep" when beeing idle.
The only "disadvantage" is that depending on the govener that you use
there might be a small lag before the frequency scales up
Actually it depends if you notice it at all
If you use govener ondemand it should be no problem
if you use e.g. smartassV2 you might consider thinking about
using some tunables that will reduce that behaviour.

Thanks, yeah, i meant for normal activities, like checking Facebook,mail, watching movies ... So ondemand mode would be better

What is your recommend governor to integrate with your Titanium-KISS kernel and what is your favourite I/O Scheduler tweaks, for daily use & heavy gaming?
I'm using smartassV2 & i set my I/O Scheduler to deadline until now, because it's peoples favourite
Should i change it to ondemmand to gain a better performance?
Hi
Actually there is already a lot of information about your question
in the KISS kernel thread.
Especially about how to tweak smartassV2 based on "profiles"

Hello
Can any one tell me what the option in the Performance means?
1- Governor
2- IO Scheduler
3-Set on Boot
and what effect will be on each drop down menu item on the phone when over clocking or under as in attached immages also
I tried to search but failed or might be not searched too good.
Thanks in advance,

They're pretty simple to understand. The governor tab just sets what CPU governor your device will use. The IO scheduler tab just sets which IO scheduler it will use. And the Set on Boot tab is pretty self explanatory. Do some research as to what each specific governor and IO scheduler does and it will make much more sense.
if you spell kernel right people might take you more seriously, just a thought.

I don't use SetCPU (way over complicated for no good reason) but Kernel Tweaker. With my experience on the F4k kernel:
JB - Interactive
KK - Smartass V2
IO Scheduler: normal phone use ROW. If you have some regular write operation, CFQ. I've tried SIO, ZEN and NOOP, overrated. While NOOP and ZEN feels really responsive (like mininium lag) but it unstable. As for SIO I don't see what people see in it. It not particularly faster, and nor battery friendly. At least that what I saw on my S3 with Pegasus governor. And I don't use benchmark, this is a pure observe from normal day-to-day use on open app, multi-tasking, browsing, etc. I've tried all mention governor for at least a week.
As for UV, I've done -1.5V (yes, not a typo) on my phone. Again, I don't bench or play games, just regular day-to-day email, browsing, photo, etc.
I'm on JB 4.2.2 Stock and using SmartAssV2 + ROW. Max freq. on 2.05Ghz. Working fine so far.
Check out this thread: http://forum.xda-developers.com/showthread.php?t=2686845 for undervolting results part (I'm guessing it's in your SET CPU too).

I'm using f4ction kernel 1.3.0 with 90hardlimit_2.05Ghz.zip flashed after the kernel with TWRP.
Also, i like CPU Control, which is very easy to use.
I don't need set cpu anymore. I turn on air plane mode at night so battery life can be longer.
And checked on cpu's cores, system automaticly control frequences.
Using SetCPU the Charging with USB takes ages
Do I need to set a profile as I have tried other apps to change stuff but this seems to be the only option for me with a modified Stock Rom
Have used these settings so far with no lags or issues .. can someone pease clarify if this is ok...
SET SCREEN OFF
CPU - 810 - 384 Gov: Interactive / Priority 100
SCREEN ON
CPU - 1566 -384 Gov : OnDemand / Deadline / Priority 52
BATTERY <45
CPU - 1026 - 394 Gov: OnDemand / CFQ / Priority 50
SLEEP 00:45 - 08.25
CPU - 584 - 384 Gov: Powersave / CFQ / Priority 49
What about Battery or CPU Temp?

Powersave governor is a governor that locks on the lowest possible speed provide by the kernel. No point on setting a speed range since it doesn't dynamically switch between them.
Well as I mention above, I don't recommend using schedule beside ROW or CFQ. If anyone still thinks SIO, NOOP, Deadline is significantly faster/better than CFQ this is a very interesting test: http://www.phoronix.com/scan.php?page=article&item=linux_iosched_2012
i've been using this phone for about 2 years now and recently moved (about a few months ago) to using a custom rom (crdroid 7.1.2). it was running smooth and cool until day the clockspeed decided to lock itself at 2000 MHz (checked using cpu-z). I do not know if this is normal but the phone's temperature goes up to 36C on idle. i thought the problem was with the Lspeed app (+custom kernel) so i uninstalled it but it didn't work. I also factory resetting it, but still not luck. will updating the firmware resolve my issue? if not, what other available solutions are there?

If you are using Fast Charging, that heating is entirely normal (happens to me too)
But heating during idle is not normal. Try changing CPU governor to something else. (like schedutil or powersave)

use Rootify, select the CPU tab located at the top then change it.
The app sometimes gets stuck at Loading screen though.

ok so it does work when i change the cpu govenor, but the only option that actually works is 'powersave' (as well as 'userspace'). all the other ones still sets it to 2GHz. 'userspace' seems to have a somewhat of an improvement but it's only setting everything to a constant value. is there a way have it set to balanced mode?

powersave forces the processor to work in the lowest frequency availible, thus consuming less power.
userspace allows the app to set the CPU frequency whatever it wants. This isn't supposed to be used in Android since changing CPU speed thorough an app is super uncommon.
Others like ondemand normally keep the power low but starts using the higher frequencies if a processor intensive app is launched.
You can learn which governors do what in this post so you can set the most suitable one for you.
