I have already searched for this, and i have no clear answer to me... Sorry if this question is repeated again.
My question is: underclock downs the speed of the processor and it increases the life of the processor and the battery. If I do with SetCPU which have profiles and "recommended" speeds to maximum and minimum, and set in one of these, is secure for my phone? there are some dangers? cons??
Thanks all!
Note: sorry for my poor english
Underclocking is safe, overclocking is not.

what is the purpose of changing the GHZ in cpu?
i dont understand this bit
can someone explain please
cheers!
Its to overclock or uderclock,or both,depending on the kernel,with a custom kernel,you can select between different options of cpu speed,and put some profiles,like when you have your screen off,charging via usb or ac,and many more.
the pros: you can have a faster phone,with the right settings,and if the kernel has underclock settings you can improve your battery life using less cpu,
the cons: at maximun speed you can damage your chip,if you use it to much time.(maximun speed is more to show off,cause it improves your benchmarks)
so is up to you what settings result better for your phone,and of course it also depends if your are a heave phone user.
cheers!
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.
Ok i searched google and here but didnt find a decent answer..
its just noob questions but i hope you guys could give me simple answers..
1. apart from getting better battery life, what's the difference between 1.2ghz with no undervolt and 1.2ghz with, let's say, -50mv undervolt?? what's the advantage/disadvantage?
2. what's better for performance/battery, 800mhz no undervolt or 1.2ghz with -50mv undervolt?
3. what's the gpu for? is it for games only?
4. is the cpu or gpu which controls the browser, i mean for rendering web pages/images/videos? for example, if i set the gpu to the lowest possible tweaks and underclock it will it affect how fast the browser render pages?
I hope you bare with me, it's been a really long time i want to ask these and find answers..

1)If you undervolt the CPU Core(s) gets less power, which is better for battery life, but maybe will decrease performance @ this CPU step
2)Performance: for sure 1.2Ghz (800Mhz is less than the Galaxy S )
Battery: you have to find out yourself which Kernel/ROM/CPU-config fits best for you!
3)The GPU is for everything grafical in some way (especially for Games etc.)
4)Maybe...
I really don't know but I don't think only the GPU "renders" webpages

Hello,
I installed cyanogenmod a few months ago and want to overclock now. Anybody who knows if it is dangerous? Is it possible that your cpu breaks down faster because of the overclocking? which are the acceptable cpu settings?
thanks

It's not that dangerous, but your cpu will wear out faster than normal, because a highter clockspeed means more heat. Acceptable cpu-settings? Depends... most phones seem to handle 691 without problems, anything above that is luck of the draw.
Set your desired cpu-settings (don't use set-on-boot)
If the setting is higher than your cpu can handle you will start experiencing crashes. If you have found a stable frequency for your phone, you can set it on boot so you don't have to think about that every time you restart your phone. If you set an unstable frequency and use set-on-boot, you will get a bootloop.

So the higher the frequency, the faster the cpu will wear out, just because of the heat. I will keep an eye on that.
thanks

When playing high-end games, I always put the cpu-clockspeed to 729 mhz...
Hi Guys,
Little question. Have somebody experience how much you can underclocking the CPU?
I asking because I want to save battery and I don't need the 2,5 ghz in my daily use.
But I heard that phone doesn't wake up if you I set the CPU frequency too low.
I am using Carbon Rom 5.1 and have root access.
PS: I have testing a little bit. My frequencies are working (using the App CPU Tuner and the recommended minimum frequency seems to be 300mhz. So I take this frequenz for my minimum).
PPS: So the thread can be deleted
