Hello, I would like to know, what is best setcpu speed to use maximum and minimum? My maximum currently is 768 and minimum 245. on scalling I checked: ondemand, or should i need to check something else? And I picked set on boot. Sorry for the questions.

it completely depends on the rom you are using and which cpu speed ssuits your phone the best as there is no confirmation which will work the best

Hello, I have an HTC thunderbolt, rooted with CM7, and installed setcpu and used autodetect and I put the CPU govern to "conservative" with minimum GHz 245 and maximum 1.8GHz and I am just wondering if this is safe? because I read some threads about Compatible kernels and I jave no idea what that means, they were also talkimg about undervolting, which agaim I do not know means, anyways thanks for reading

If your device will run reliably at 1.8GHz, then there's not much to worry about as long as the voltage isn't too high. High voltages and heat can shorten the SoC's life or kill it altogether. Generally, I don't recommend running that fast because the performance increase isn't as great from 1.6GHz to 1.8GHz as it is from 1.41GHz to 1.6GHz. These cores weren't meant to run any faster than 1.5GHz really, and anything past that doesn't increase the performance as much as the numbers might suggest.
Also, a conservative governor probably isn't ideal if you're willing to run a device that fast. That governor would seldom, if ever, use that kind of speed. I'd suggest smartass, smartassV2, ondemand, or interactive if you're looking to see a good boost in performance.
If you're looking for an app to view and adjust voltages, IncrediControl works well. For all the nitty-gritty of overclocking, I'd recommend reading my OC guide. It's in the "Second Post" of my Q&A thread. If you've got any questions, feel free to hit me up.
So does over clocking just speed things up? What are the real benefits

I look at it like this. My screen eats up most of my battery. The less time it's on, the better. Overclocking uses more power for the CPU, but the display spends less time telling you it's waiting. It doesn't really add functionality, just speed and efficiency.
I m on cyanogenmod 7.2 by fat.. i just wanna know which is the best governor for faster performance and better battery saving...
Pls do reply

Depends on user requirements but for me it is smartass v2

SmartassV2 suits best for my regular usage.
I use SetCPU to set diff CPU frequencies. (zImage v1.5 kernel)
Normal: 160 Min 735 Max -- SmartassV2
Charging: 120 Min 600 Max -- SmartassV2
Screen Off: 240 Min 320 Max -- Ondemand
Temp > 40C: 120 Min 480 Max -- Ondemand
Battery <11%: 120 Min 320 Max -- Conservative

SmartAss V2 is more balanced yet more battery wise than Ondemand.
InteractiveX is I think the best battery saver

u shouldnt be doing that.
ever wonder why nofrills cpu control doesnt include cpu freq/governor changing based on profile? because the author stated that those changing should be done natively by the cpu governor, not by the phone itself.
and smartassv2 already include max cpu freq on screen off profile and for my kernel i already set it to 320. same as ondemandx, savagedzen, interactivex and smartass, i already set screen off max at 320.

Me too, conservatibe has the best powee savin.g. Of course, litte bit slower but not even noticeable, and good battery life.

Conservative + underclocked = Amazing battery life (nothing extraordinary but amazing from Ace's low standard)
And performance....wen gaming...wid just slight overclocking...with charger plugged in.....with back cover out...feels like its gonna burst into flames...

I'm getting what your point is. But, I have several questions:
1) Why that guy developed an application -No-Frills CPU Control when all the features he presented where available under Settings > CyanogenMod Settings > Performance?
(And then he said "you might need a custom ROM like CyanogenMod", if he didn't give profile feature)
2) When I go to /sys/devices/system/cpu/cpu0/cpufreq/smartass I can't read any of its set frequencies.
3) And how come SetCPU is any different then switching the governor manually? Standard procedure also changes the governor as SetCPU does. So how come it is harmful? Just because SetCPU might switch profile too often?
I used SetCPU just to save more battery. I'll disable SetCPU and observe CPUSpy stats and let you know about freqs switching.
No Frills works on a stock ROM dude, he said you might need to use CM because maybe he's afraid stock kernel has a freqlock thingy.

Best governor, hmm which state ? Arnold, that artist ? Hhhhh
Linux kernel governor, hmmm I dont care on these. I use default ondemand, and burnout battery that I dont care, as long as i can see elctricity terminal or I have to use 60Ah car battery in my back hhhhhh.
I didnt use my ace on scientific processing, connecting thousand of android doing parallel processing looking for alien. So 8 hours battery is enough for me.

Hello,
I'm writing this thread to know which processor options would be optimal in our minis. The best settings, which give me the best performance/battery, I've found are:
CPU Governor: SMARTASSV2 (Default)
Min Freq: 19MHz
Max Freq: 748MHz
Undervolt: TRUE
I'm also using Apex Launcher. Which settings are you using?
Note: This are just my results, be careful when you change your processor settings.

Whats the purpose of Undervolting when you have it's max frequency as overclock?

Because it undervolts on every frequency below 600, and his minimum is 19, so when the phone is idle or doesn't need all of the processing power he saves battery
The SmartAss governor is very good at picking the right frequencies for any given job, so it doesn't allways run on 748Mhz, not even when you're using the phone.

That is the same very purpose of SMARTASSV2 to undervolt your device when idle or on sleepmode and overclocks it when on process. So ticking the undervolt wont affect your device because the one that manage the frequency will be the COUgovernor.

The SmartAss Governor only governs the frequencies, not the voltage that the Processor uses. there is a difference between the speed the cpu runs on (Mhz) and the amount of Electricity (Volts) it gets fed
Say Qualcomm has said it needs 5 volts to run at the stock frequency of 600Mhz, then the processor will always get 5 Volts, no matter which frequency it uses.
Undervolting will feed it less than the 5Volts when the frequencies are lower, SmartAss won't do that, it will run the 19Mhz still on 5Volts.
(Voltages are examples, i don't know the exact values, but I know that running on 122 or less will be stable on less than half of the nominal power)

nice to see some piece of truth over here (not perfect, but well explained)
de-noobing is good from time to time
xda is overcrowded of false answers given by people thinking they know but don't
anywhere, at anytime, newbies asking get fake answers from people wanting to help but failing to do so , due to lack of knowledge.
as everyone, i might be one of these, but try not to be.
make sure you know what you are talking about before spreading your (incomplete or false) knowledge

Hey, thanks a lot for all the replies. I had no idea why my settings worked like i wanted.
I just installed the cpu-z to see the processor information and i notice that the maximum clok speed of s2 is 1.20 ghz but it only reach maximum upto 800mhz the clok speed not reach it maximum at 1200mhz why? What is the problem explain i am in worrie.

Powersaving mode limits your CPU to 800mhz.

Um, maybe it's a stupid question but is the InteractiveX governor ramp up to highest possible maximum frequency or just to User maximum configuration freq? Im asking because it is not stated.
