Which setcpu profiles do you use?

Hi,
I have installed and added setcpu profiles but i am not sure they are correct choices for me. I have virtuous unity rom with v4 kernel.
ac charging 1.7 ghz max
Battery under 70 1.5 ghz max
Battery under 50 1.2 ghz max
Battery under 30 1.0 ghz max
Temperature over 50 800 mhz max
(All of profiles have minimum 368mhz of speed)
All of them are ondemand but i dont know when to use conservative. And are these clock speeds good for us?
Can you help me about this?

If youre using virtuous unity, you shouldnt use setcpu and use the virtuous overclock app. Its essentially the same but virtuous oc is much faster in changing your speeds.
My speeds for virtuous oc are:
Max wake: 1.5ghz
Min wake: 245mhz
Governer: ondemand
Max sleep: 368mhz
Min sleep: 245mhz
Governer: conservative

I'm using CM7 Nightly
Latest Umaro kernel
Screen off = 280/380 powersave
<101% = 280/1.7 ondemand
<40% = 280/800 conservative
charging = 1.0/1.7 performance
temp >50c - 280/380 powersave

I don't.
As stated in the Unity notes (on their website), and as evilcuber mentions:
Virtuous overclocking daemon will automatically be disabled if an overclocking tools (such as SetCPU or CPU Tuner) is installed. Installing these tools is not advised, as the virtuous_oc daemon responds far more rapidly to screen state changes than any Android (Java) application.

I was using setcpu to see momentary clock speeds then decided to create profiles. So it is better to stay with virtuous OC application. I want to ask another question; does sleep clock speeds of cpu effect waking up time?

Same here, on CM7 though (which has a built in CPU setup). I haven't used SetCPU in months. 806mhz max / 245mhz min, OnDemand governor. One less app running, the same or better battery life, and no sluggishness with profiles.

It can. If you set a low screen off profile like 245/245 or 245/368, your phone may lock down and not wake up properly, or take time to "speed up" when you unlock the phone, which can sometimes be noticeable depending on your phone setup.

the best way is "try and see what happens" I ill try low screen off speeds and try if the hone wake up late. if so, i am going to get clock speeds higher then it was.

Minimum cpu frequency

I am running Bionic cow v7.
Why the minimum clock speed is set to 245Mhz instead of 122Mhz?
Shouldn't setting it to 122Mhz saving a lot of battering while idle?

You can set it as you like using setcpu. It depends on you. Cause default setting is always set to 245mhz.

Yes I know, I am actually using No-frills CPU Control that is free.
I was hoping somebody already did a benchmark to see how changing that setting affects the performances and the battery

KISS-Kernel

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 )

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.
max

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"

What governor did you use and what frequency did you set?
I had same problem when using brazillianwax (and eventually, lulzactive and SavagedZen)
Recommended to use SmartAssV2 for the governor

I set my friend wonder with 368 i believe in min frequency and max 1ghz, and it is still smooth with smartassv2 / lulzactive / brazilianwax. And it is battery friendly either capping the max to 1ghz only. You should try that and see the changes. Although the battery is not drastically save but it is slightly different from capping the max to 1.4. It all depends on the kernel you're using though. Whose kernel you use?
And for your song problem on screen off it is caused by your min frequency it is too low for running app in 192, try to raise the min frequency to 245 / 368. For my friend phone 368 is the most stable for what your facing.

[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
