Been wondering this for a few days. Does setCPU raise CPU voltage when it overclocks ?
Because if it doesn't, then battery life shouldn't be affected.
I'm not sure about SetCPU itself, but in order to overclock, the voltage must be raised anyway - for example on my milestone ( using milestone-overclock ) when i set the maximum to 1.2Ghz, i have to change it to 80vsel. ... so battery life will be affected when you load a custom ROM or load the kernel module to overclock.
so when you load the overclocked setting in setCPU, it uses the vsel specifed from there, right? which would result in more voltage
Guys, can you help me out?
Something odd has been happening on my phone. I run Matrix kernel 9.5 on Lazy Governor and everything's fine, but when i turn it to Ondemand the phone starts to reboot randomly.
Does anybody know what can it be?
Thanks!
Try running different min and Max frequencies and see if that helps.

have you fiddled with the voltages
I tried different min and max frequencies and I also played a little bit with voltages. What i realized is that if the voltage is too low for a particular frequency my phone reboots. Do you know how can i teste how far i can get with OC?? If i OC to 1.2GHz for instance, and my phone reboots... Can i put a higher voltage to 1.2 frequency in order to get it working?
Thanks in advance!
Try to increase the voltage as small as possible until it not reboot
But be carefull! Increased voltage can damaged your cpu.
I prefer dont do OC, this device is fast enough on default freq.

I'm in a city where the average temperature is 35° daily and my tablet gets pretty hot using the stock kernel that comes With cm10.1. Which other kernel is best suited for hot environments (ie. Undervolting etc.)
Also hoping for a kernel that extends battery life.

Try NEXT kernel. CPU voltage 100mV lowered than the original voltage. GPU and IVA (multimedia co-processor) voltage 25mV lowered than the original voltage.

Next kernel from me too! Just perfect!
There isnt a best kernel to use in a hot country. Any Kernel that allows for overclocking and is stable will work for you. You can then set it however you want.
NEXT kernel non overclock version (*-nooc-*) feels quite cool on my P3100.
Hi, I have some questions with kernels, overclock and governor. I'm using cm10.1 or cm11 or any JB or KitKat and I have some questions:
1- Wich are the best governor for daily use?
2- Wich are the safe levels to overclock the phone?
3- I saw that a lot of people uses OC in Min 122 and Max 806, Is this possible with few risks?
4- Wich are the risks of OC?
5- Should I use a specific kernel? Or the one with the customs ROMs are enough?
5- More questions after I get more information.
Thanks.
PD: I made this thread because the others OC threads are very old, before JB and when ICS was just released I think.
OC 806 can damage your phone for ever manage carefully this

And what are the safest levels? And best governors? Im actually using smartass min 480 max 729
Overclocking will not "damage your phone for ever." Some of the P500s are stable at higher clock speeds than others, which is typical of mobile CPUs (even the two cores of my Sensation's CPU are stable at different maximum clock speeds). IIRC, my Optimus T was only stable up to 729 MHz. If you try to overclock higher than your phone is capable of, then it will freeze or reboot. There really isn't a "safest" level; any clock speed that your phone is stable at is going to be perfectly safe. Run a stability test or benchmark app from the Play store to check stability. IIRC, another easy way to test stability on the P500 is to open a camera app. The camera tends to crash the phone when the CPU is clocked too high. If you manage to crash the phone by doing any of that, then I recommend dropping down to a lower clock speed. Otherwise, the phone is fine and you can test a higher clock speed. FWIW, I'm pretty sure that most P500s are stable up to 729 MHz, but many of them are not stable higher than that.
I personally like to use Interactive governor. I think I used Interactive with min 480 and max 729 on my Optimus T. Governors Explained

1. I use smartass as governor (well on the jenkins build). It has a balanced battery and performance I think.
2. Regarding safe level, no overclock is safe, unless it is specified that the processor can handle overclocking over a certain period of time. That's why it is designed for a certain clock speed, because at the guaranteed clock speed you can get the most out of your processor without even breaking it.
3. Well overclocking on android depends on the ability of the kernel to handle overclocking situations. Some kernel can handle overclocking very well that the noticable errors are up to a minimum level. While setting the frequency to Min 122 and Max 806, it is not really safe to go to a maximum of 806 Mhz. As specified the maximum (safe) frequency of the processor is 600. so even going for 601 above or to 710 even if other claim that 710 is still a stable frequency will not guarantee that it will we stable at 710. Regarding the risk. overclocking in the first place is risky.
unless yo go y.o.l.o over your hardware.
4. Risks are. 4a. going beyond the maximum temperature your hardware can handle. can lead to fire (yeah it is true).4b. boot failure 4.c crashing of applications. 4.d etc etc.
5. Before, we use to have different kernel developers and different rom developers. as the the passed by and newer devices are being developed, some migrated to newer devices and abandoned the development for our beloved phone. Now I think only 1 developer is still developing (original development not just cuztomizing and stuffs it with design) androidmeda (check "jenkins armv6") and the kernel included in the rom is sufficient enough to handle overclocking (used it and set the freq to 320 - 710 at smartass). I also use sweetnsour's kernel before but i think he too abandoned the development)

That isn't true. Processor manufacturing is inexact, so some processors end up with higher clock speed capability than others. As the maker of a device, you have to set the clock speed low enough that ALL of the processors in ALL of the devices function properly. Setting the clock speed conservatively means that most or all of the devices are actually capable of functioning at a higher clock speed, which in most cases -- and certainly in the case of the P500 -- is completely safe. And it is extremely naive of you to believe that every processor or computer you buy is running at the "best and safest" speed as tested by the manufacturer. CPUs are often significantly underclocked simply to allow manufacturers to differentiate pricing. The same thing is done with finished products, including smartphones. For example, my HTC Sensation has a Qualcomm MSM8260 clocked (originally) at 1200 MHz. The HTC Sensation XE has the exact same processor clocked at 1500 MHz.

Again, it is nonsense to say that overclocking this phone "is not really safe." You won't find one example anywhere of a person who has damaged this phone by overclocking it. These things don't get hot enough at any clock speed to damage the hardware.
4. Risks are. 4a. going beyond the maximum temperature your hardware can handle. can lead to fire (yeah it is true).4b. boot failure 4.c crashing of applications. 4.d etc etc.

4.a. Heat is probably the only legitimate concern with overclocking a smartphone, and that's exactly why there is no risk with the P500 -- it doesn't get anywhere near hot enough, at any clock speed, to cause any damage.
4.b. This shouldn't be a problem. If your phone is not setting clock speed on boot, then a crash/reboot will send your phone back to the original clock speed. Even if you make a mistake and change a clock speed that is being set on boot (which I actually did by accident just yesterday), you can boot directly into recovery and restore a backup.
4.c. Who cares? As I said before, if your system is unstable as a result of overclocking, then you should lower the clock speed. That isn't a problem.
4.d. *sigh*
But to each his own. If you don't want to go "yolo" with your antiquated $50 smartphone, then by all means, keep it at 600 MHz. Nevertheless, there is absolutely no way that you would damage it by overclocking, regardless of what you may believe.
Well, its overclocking and not overcloaking.
Small error, but make changes in the OP

I wrote it bad in the title, but in the middle of the post it was OK. Thanks anyway, ****ing spanish that you read it like you write it, or viceversa.

The phone won't work above 729MHz. And the only risk i can thinknof is depleting battery life faster.
Im actually using interactive min 480 max 806.
That permit no lag and normal reactivity.
Obviously there is a battery drain than normal.
I've also use a seeder application.
I am having trouble regarding these: undervolt
maximum cpu frequency
maximum gpu frequency
cpu thermal throttling
So i downloaded kernel :Sultan-kernel-Pure-v1.7.0-Pyramid-Aroma.zip
6.5MB, which I think is the latest one. But i am not familiar with those because it is my frist time to flash my own rom and kernel. I've done everything right but can you help me set up the kernel? which is best? because there are numbers in it and i dont know what to choose. Also what is best setting for saving battery life? overclock, underclock, undervolt, cpu freq, gpu freq, thermal throttling., what are those
I also apologize for posting like 3 threads for this because im a newbie. I hope you consider. HELP me please.

for good battery life put these settings:
cpu freq: whatever freq you want but maximum at 1.5ghz
gpu freq:266mhz
undervolt:whatever value you want but maximum -50mv
