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

Which set cpu scaling govenor works like stock? I never knew the difference between all the options.
On demand is stock
Conservative is basically like stock but will help battery life
Performance keeps it running at max always
I powersave keeps it at minimum that's all I really know

ok idk ow to overclock correctly i need a way to make this sense 3.5 rom less laggy an run more smoothly, can anybody help me with this???
Yes just use Daemon Controller (basically functions the same as SetCPU) and set your maximum frequency. For most ROMs I would set it around 1.5Ghz, and set the governor to smartass or smartassv2. The governors will depend on the kernel you're using. For a good sense kernel, I would use this one.
Additionally, you can download Incredicontrol via the market and that will enable you to adjust your voltages, based on the frequency steps. A lot of people prefer to bump the voltage up or down 25% to increase performance or reduce battery drain.
I AM NOT RESPONSIBLE FOR ANY PAIN AND SUFFERING YOUR DEVICE MAY INCUR.
If I helped, slap my Thanks button around a bit.

0k the number says 245760 i cant tell which is the 1.5 ghz?
245mhz... That is your lowest frequency. You'll set that as your minimum. Your max should be set at 1497mhz. It'll have some numbers straggling on the end but disregard them. 1497mhz = 1.5Ghz.

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"

uh, okay...i'll re-read the info once again :good:
Hi i have ARHD on my phone with the XM Kernel. I was slightly suprised in the Trickster MOD app, the max clock speed is 1.3ghz. Yes i know i can OC to 1.5 but im not sure what is setting this. When i had ARHD installed with stock kernel it was showing 1.3 as default. I assume that was set by the ROM. But i installed this kernel and still has 1.3 as the default.
Also the default govenor settings for the gaming one has the boost_freq set at 1300000, which is 1.3ghz, that can be changed to 1.5 also. But surely the boost freq would be the max freq no matter if you move the slider to 1.5 in the basic controls? But i would be suprised that the gaming govenor would underclock the cpu, surely for gaming you would want the phone maxed out?
Is this expected with the XM Kernel and the ARHD? And if so, is there any things i can change in the govenor settings to make sure it performs at absolute max?
It's kernel related; Xmisters' kernels since 188 have a hard cap(1.3Ghz) by default, but using trickster mod, or another o/c apk, you can raise it to the stock 1.5Ghz(tick 'set on boot' to ensure it stays at 1.5) The best settings are trial and error, tbh, I use touchdemand/sio though smartmax seems to be the best balance.
Thanks for the answer. i can change it to 1.5 easy enough, but if you look in the govenor control, the boost_freq is is set to 1300000. If i left it at that, would it prevent the cpu from going up to 1.5?

you have sleep (lowest CPU can go), ideal freq(the speed the CPU aims for while awake), touch poke (when you touch the screen), boost (what it boosts too to prevent lag) and max (CPU flat out)
Setting the boost to 1.3 will still allow the could to run at full speed.

That makes sense, cheers. So its probably a good idea to leave it as it is then.
Well, I am rooted and on cyanogenmod 10.1..
If I understand corrrctly, you can underclock the device with just an app?
If so, what app can I use (considering its DHD rooted with CyanogenMod 10.1)?

Ace OC tool!

I think the reason I like the Andrev OC Daemon is because you can automate it to use a lower CPU setting when in deep sleep.
For example, when the screen is on, you can set the max CPU to 1.2 MHz, and set it to reduce this to 256 KHz when you lock your phone.
So easy to use, and the battery lasts an incredible duration longer. I've had 0% decrease in battery for the past 2 hours with the phone on, but on standby.
Highly recommended.

Sorry if i misunderstood, but there are performance settings in Settings menu of CM 10.1.So i have set max CPU frequency to 806 MHz and min to 149 MHz and marked "set on boot". Isn't it underclocking ? Off course you can't undervolt the CPU, but he asks just to underclock.

Yes, that would be underclocking, which has shown results in battery improvements. Essentially, you are trading speed for battery life and its all about getting the balance right.
Obviously, when the screen is turned off, and the phone is inactive, you do not need the CPU to hit heights of 806 MHz, which is where Andrev OC Daemon comes in..
You can set it so that the phone uses up to 806 MHz when active, yet not exceed 149 MHz when the screen is inactive.
I have seen VAST improvements in my battery life using this OC/UC tool.
And I really can't over-exaggerate the 'vast' in that sentence..
