Question for undervolters:
How long did you run a stress test until you deemed a voltage/clock to be stable?
I'm impatient. I only ran each voltage drop in 25 increments at each frequency for about 5-10 minutes at each increment. I ran quadrants, linpacks, antutu benchmark and setcpu cpu stress tests. On my phone, when the voltage was too low, it would lock up and reboot fairly quickly in my testing.
So my methodology, which is probably kind of crappy...
1. Set governor to Performance so the phone would run at max speed all of the time.
2. I use a min of 245 which I wasn't planning on changing so I set my max to 245 also as a start -but obviously you can set your min to whatever and start your max at that same freq.
3. Lower voltage in Incredicontrol -25 and apply. DO NOT SET ON BOOT.
4. Run stress testing, quadrants, linpack, antutu benchmark until I get bored--usually about 5 - 10 minutes at each decrement. (I was doing this while watching tv so it wasn't as boring as it sounds.)
5. If the phone didn't lock up or reboot, repeat steps 3 and 4 until you get a voltage that causes your phone to be unstable then stick with the last good voltage.
6. Repeat steps 2 - 5 for the next higher clock frequency.
7. After I got my table set up the way I wanted, I still didn't set my voltages to be applied on boot until about a day after and it hadn't locked up or rebooted in that timeframe--but that's me.
I got tired of doing this at about 768 mHz so I kind of stopped trying to go much lower than just -25 figuring the phone spends most of its time at idle and lower frequencies anyways.
