Currently looking into the process of OC'ing and UV'ing. It would be cool to see what results you guys have got and what difference in battery life you perceive!

Im currently at stock 😁

I have the same PVS CPU than you with 0,9 Volt at 384Mhz and 1,05 Volt at 1,5GHz.
I could undervolt 50mV accross the board; undervolt the lowest frequenz (384Mhz) to 0,73 Volt and overclock the CPU to 2,0Ghz max.

Im running Cyanogenmod with Glitch Kernel and use Trickster Mod for OC and CPU UV.
With Glitch Kernel I can even undervolt the GPU 100mv accross the board with an increased max GPU of 450Mhz.
(More is possible, but I nearly dont play games with my tablet)

With this I get about 8 hours of SOD time with Surfing.
When I'm on a long business trip and use my N7 for (Kindle and pdf) offline book reading I reach something like 13-15hours SOD time.

I know a bit how i can get to know my cpu's pvs stepping, but since you have the same as me, what is it exactly? And is it considered a fast, normal or slow binned cpu?

Whats the best way to test stability? Ive got this app https://play.google.com/store/apps/d...into.stability but i dont seem to get any wiser... Anyone know what i should do?

yup, run that for like 30mins on classic test, should be fine if it doesn't crash

I did that, but with voltages that are stable there, antutu crashes. And with voltages that are antutu stable, my device crashes randomly. I can run the scaling test with very low voltages across the board for more than an hour and it doesnt crash.
With other apps it just crashes.

This is an experimental undervolt that rarely crashes when switching apps:

I dont know which clock speed and its corresponsing voltage is unstable because the clock speed ranges from 384 to 1512 mhz and i dont have a crash log.

So I added 12.5 mV across the board, and this hasnt crashed so far!

But, being the perfectionist that I am, I want the Ultimate Undervolt. Is there a way to see what frequency you are running when it crashes?

I achieve stable 700mV at 1026MHz...

30mins stress run on "stability test" app and on stress run on "setCpu"

At 1134MHz the tablet freezes for the first time when I switch to 7875mV

Isn't it weird??

I dont think the stability test app is working. I could undervolt 1512 mhz to 900mV and have it run stable, but everyday use stable is with 987.5mV

Will you post your voltage table?
What are the Kernel setup settings that you choose and have you ever OCed to 2.2 and still get good undervolting?
