So I downloaded the DX/D2 Overclock app from the market, but I don't really know what to set it to. I'm a heavy texted that uses a bit of 3G. Not a lot of gaming, the most I do is Angry Birds or a GameBoy emulator.
Based on that information, what would be some good overclock values for me to set?

personally, i would set it at a medium voltage with the scaling govenor on performance and the scaling bars set to max 1000 and min whatever you like....i keep it at 1000/1000 but battery is costly

If you want to overclock I use the 1.25 low voltage.
After seeing this thread I got the app and I'm at 1.15 ulta low voltage. Voltage is similar to stock.
Stock. Overclock
Slot 1 - 400Mhz 33v 400Mhz 36v
Slot 2 - 600Mhz 48v 700Mhz 51v
Slot 3 - 800Mhz 58v 900Mhz 56v
Slot 4 - 1000Mhz 62v 1150Mhz 62v
Not a massive increase in speed but still noticeable. Hopefully keeping the voltage close will help prevent overheating. Probably stay at 1.15 for a few days to see how everything goes. If it's stable and doesn't overheat and depending on how it affects battery life I might crank it up and see how it goes.

I run 1.35ghz low voltage. Rock solid and no heat issues.
As long as you don't set it to boot with untested settings you should be fine experimenting. I tweak settings and run quadrant to check for performance. Trial and error.

(Q) can anyone tell me the consequences of overclocking too high

Your phone will reboot, it burns through your battery life quicker and overall can be hard on the hardware for your phone over an extended period of time....same as a computer

Cool that's what I thought...I recently installed the GB them and I thought that had something to do with it but them remembered that I had boosted the clock sod....hasn't booted on me since I dropped it back down a lil.

I find that often the highest overclock kernel's usually don't work for most people. Pick one a few notches down and you will most likely enjoy the benefits of overclocking without any issues.
With ultra low voltage kernels, it is possible to overclock and still use less battery since the lower voltage requires a lower current.
I have Droid X overclock app from jrummy and was running at ULV until I decided to see what the lowest possible vsel is while keeping stability. What is vsel anyway? Is it actually voltage? so stock at 350000mhz has 32 volts to the cpu? And also is it bad to run my phone as low as it is. I have had no reboots in over a week sense I applied "custom" settings below
Stock settings
350000=32
500000=40
800000=53
1000000=62
Lowest setting
350000=17
500000=27
800000=37
1000000=47
Has anyone tried to push the voltage above 1350mv on their phones?
I think that my Core 2 has a recommended maximum voltage of 1.36v and while overclocking I've pushed it to about 1.45v 24/7. I know that PCs and phones have differences and that with the added voltage comes with risk of your HD2 having a short life. Some people make it seem as if the voltage hits 1375mv it will disintegrate on the spot..
I just want to see if i could get a more stable Overclock or even push it a little further, 1228 perhaps?
Anyone? Im sure someone knows something...

Hi,
I'm reading topics like franco kernel or faux kernel or cpu binning, and i don't understand what undervolting is using for... And how doing it ?
Plus, i don't understand what cpu binning is for, even if i get there is cpu slow and some fast.
Thanks for your answer !

The binning decides which voltages you can run your cpu on, those with better "quality" cpu (faster) can run a lower voltage. This does not affect frequencies, so you don't have to worry if you have a nominal binned cpu for example.
As a general guideline, I've read that faster can be undervolted -150 mV, fast -100 mV and nominal -50 mV.
YOUR MILEAGE MAY VARY, SO ALWAYS USE PRECAUTIONS WHEN DEALING WITH UNDERVOLTNING. USE ON YOUR OWN RISK
How to find out which binning you have and more information:
IAmAN00bie said:
Hey fellow Nexus 4 owners, I heard a lot of rumors that the "Nexus 4 uses left-over parts" from the Optimus G. To that end, I want to find out the general quality of our CPUs.
Basically, when Qualcomm makes the APQ8064 chip that you see in our Nexus 4, there are 4 different "types" based on how it meets their quality standards. These are Slow, Nominal, Fast, and Faster. The main difference IIRC between these types is how stable each can handle undervolting. CPUs that are "Fast" for example come pre-configured at a lower nominal voltage than a "Nominal" type CPU, and more so than a "Slow" type. (Does this account for how some people's phones generate less heat? Maybe, maybe not. IIRC, there's like only a -100mV difference between Faster and Slow out of the box, however Faster CPUs should be able to handle lower voltages than Slow-type.)
To find out what binned CPU you have, I recommend the following:
YOU MUST BE ROOTED!
1) Install Terminal Emulator
2) Reboot your phone
3) Open Terminal Emulator, and type:
Code:
su
dmesg | grep PVS
A line should be outputted that tells you what type you have.
For example, mine is NOMINAL. http://i.imgur.com/MUXrs.png

Is running a lower voltage is dealing with performances or only with battery ?

It only affects battery (mostly temperature actually). Basically how good your chip is determines how much voltage it requires to run at a certain speed. Because not all chips are created equal and the manufacturer has to make sure that all of the chips run stable, they set the voltage levels at a conservatively high number. This means that unless your chip is the worst chip that LG expects to produce, you can run your cpu at lower voltages than stock.
It was theorized that the binning of the cpu would be a good indicator of how good your chip is but it looks like it might not be the case.
To undervolt, you have to first flash a kernel that supports it (most custom kernels do) and then download an app like Franco kernel updater or system tuner and you can start adjusting voltages.
Some things to note before you start: if you undervolt too low your cpu becomes unstable which means it will freeze your phone and force it to restart. This does NOT damage anything physically so don't be afraid of it. But this means that you should not have the app set voltages on boot while you are experimenting with them. This would open up the possibility that you set a voltage to an unstable level, forcing your phone to reboot, upon which the app will reapply the instable voltage. This will keep you in a boot loop and force you to re flash the kernel) and/or rom. Just keep it manual until you have set of stable voltages.
Good luck!

I have a nominal one. The default for the lowest frequency (384, i dont remember exactly) is 900. I made a -150 for all frequencies. it has been running for 3 days without a restart. And for my own feeling, games as well as the whole phone run normally. And when running games, it is less hot than using the default one (900).
Hm, i see, thanks !
Another (and i hope the last one) question, how could i know if i set the voltage to the right value ? Is this any app for testing if it crash ?

Basically if it runs, you're fine. You want to find the lowest voltage for each frequency at which your phone will run normally. One way of doing this is setting your min and your max cpu frequency to the one that you're testing and adjust the voltage and run a cpu intensive task like a benchmarking or playing a video. However, I find that they are a little more finicky than that and you may find that in normal usage, a voltage that you tested doing that will still crash your phone.
I personally do it over a week or so normally using my phone and gradually adjusting the voltages down to the lowest stable
