[LG Optimus Black] knzo:
Note 31/07/2011: Updated for Nova Script

Note 10/08/2011: The method is a bit different but you get the overall idea after reading this

II. How to overclock (applies to Nova)

So, you just want to overclock eh?

Ok, you have several ways to do this:

a) Using Nova built-in overclock script

b) Typing commands by hand (terminal, adb, etc)

(No, SetCPU does not work on OMAP devices, only for choosing governors)

I will also cover how you get your Optimus Black to auto-overclock (at least in Nova).

But first of all,

very very important

, please open this spreadsheet - it has a listing of values of clocks and the corresponding voltages which can be: stock ones, low ones, ultra low ones and high ones. For speed & battery compromise, I suggest low ones. However, if you're a gamer, you better stick with stock for instance.

Print that.

Done? let's move on.

a) Using Nova built-in overclock script

Now, I made a hilariously simple script for you to use on Nova to facilitate your overclock.

You just have to open the terminal application and:

Type "su" (without ""), press enter, click allow if it asks - very important step (needs root).

Type "nova" (without ""), press enter and congratulations, you've just entered the nova (overclock) script!

There just choose "overclock!". Remember, first the voltage, then the clock.

For example:

Type "su" (without "") on terminal, press enter. Click allow if it asks.

Type "nova" (without "") on terminal, press enter.

Type "1" (without "") and press enter.

Type "62" (without "") and press enter.

Type "1100000" (without ""; this is 1.1 Ghz) and press enter.

Enjoy your overclocked and undervolted phone.

Oh, terminal emulator has some kinks:

- If your keyboard disappears hit menu button and click 'toggle soft keyboard'.

- If you exit and it stays on the statusbar, re-enter terminal, hit menu button and click 'reset'.

P.S. You can also run this via ADB.

But how to auto-overclock on boot?

Now in latest Nova Script it will ask you if you want to set them on boot!

If by some reason you didn't test and found out that your device is stable with those settings and you can't boot your device or if it does it's all laggy and craps, you can just power it off, remove microSD card, use an adapter and put it on your PC or laptop and remove the file, then insert the microSD card back and reboot the phone. I chose a file in the microSD card especially because of this safeguard.

b) Typing commands by hand

If you're feeling too pro for the overclock script, you can just type them by hand:

- echo "xx" > /proc/overclock/max_vsel

- echo "xxxxxxx" > /proc/overclock/max_rate

If you want to auto-overclock, use the same method as above.

This is it. Simple.

A few reminders

:

Voltage first; then frequency.

Check the table in the beginning of the post for frequencies and recommended voltages

Frequency has to be for example 1200000, not 1.2. It's in Mhz, not Ghz.

Test the **** out of your device with a frequency/voltage before setting it at boot.

Most Optimus Black won't be stable beyond 1.2 Ghz.

If you can't boot or are having problems because of auto-overclock, just delete the file.

Done.
