I'm running at the following settings which have been fully stable for 2 months now. Siyah 1.8.9 + CM 10.1 (24/01/2013 nightly - I still feel this one has given me the best battery life so far combined with the undervolting). These are the settings I'm on right now:

CPU:
  • Governor - pegasusq
  • Max Frequency - 1600 MHz
  • Min Frequency - 200 MHz

CPU Voltages:
  • 1600 MHz - 1250000 ÁV
  • 1500 MHz - 1200000 ÁV
  • 1400 MHz - 1187500 ÁV
  • 1300 MHz - 1137500 ÁV
  • 1200 MHz - 1087600 ÁV
  • 1100 MHz - 1037500 ÁV
  • 1000 MHz - 987500 ÁV
  • 900 MHz - 937500 ÁV
  • 800 MHz - 900000 ÁV
  • 700 MHz - 875000 ÁV
  • 600 MHz - 850000 ÁV
  • 500 MHz - 837500 ÁV
  • 400 MHz - 812500 ÁV
  • 300 MHz - 762500 ÁV
  • 200 MHz - 737500 ÁV

GPU Steppings:
  • 1st Step - 266 MHz
  • 2nd Step - 350 MHz
  • 3rd Step - 440 MHz
  • 4th Step - 533 MHz
  • 5th Step - 600 MHz

GPU Voltages:
  • 1st Step - 875 mV
  • 2nd Step - 925 mV
  • 3rd Step - 975 mV
  • 4th Step - 1000 mV
  • 5th Step - 1025 mV

The GPU settings aren't anything special, but the CPU undervolting is pretty extreme (more than -125000 microvolts for some steppings). These settings probably won't be 100% stable for most people.

As I can see you have also for cpu undervolting -125mV! I think that one is also extreme. And how about cpu, battery temperature?

I'm looking for some way to add more voltage on GPU than 1.2v as Siyah kernel offers. Mine runs 700MHz @ 1.05v but completely locks up on 800MHz @ 1.2v.

The best way is to find it out yourself by following the steps in op for an optimal value
