I recently changed to Cyanogenmod 10 nightly builds, using Siyah 4.1.5 for the Kernel. Figured I would update my config.

Again, a user (geko95gek) over at XDA Developers has put in a lot of testing creating a “MagicConfig” which I would recommend you checking out over here.

Note: If you decide to do anything like this to your Galaxy S2 and it breaks, I will not be held responsible. 

Rom: CyanogenMod 10 (Nightly)
Baseband: DVLP3 (Telstra)
Kernel: SiyahKernel (Latest)
Applications: ExTweaks

SETTINGS (CPU):

• GENTLE_FAIR_SLEEPERS = Enabled
• CPU Hotplug = Default
• CFS Tweaks = Linux Kernel Defaults
• CPU IDLE Mode = AFTR + LPA (default)
• Smooth Scaling Level = 800Mhz
• MAX CPU LOCK = Dual core mode
• CPU Undervolting = -75mV (all frequencies)
• CPU Step Count = 16 (All available)
• Default CPU Governor = pegasusq
• Default CPU Scheduler = noop
• Scaling Max Freq = 800Mhz
• Scaling Min Freq = 200Mhz

All other CPU settings as stock.

SETTINGS (GPU):

• MALI TOUCH BOOST LEVEL = Step 2
• GPU Freq Step 1 = 40Mhz
• GPU Freq Step 2 = 66Mhz
• GPU Freq Step 3 = 100Mhz
• GPU Freq Step 4 = 200Mhz

SETTINGS (GPU Voltages):

• GPU Voltage Level 1 = 800mV
• GPU Voltage Level 2 = 800mV
• GPU Voltage Level 3 = 800mV
• GPU Voltage Level 4 = 950mV

All other GPU settings as stock.

SETTINGS (Screen, BLN & Misc):

• Touchmove Sensitivity = 3 pixel
• MIN_BL = 40
• MAX_GAMMA = 22

• Android logger = Disabled

All other Screen / Audio / BLN / Misc settings as stock.

Some people have been successful in undervolting the CPU to -100mV, but mine was unstable so went to -75mV. Each result may vary.

Warning: Again, you may break your device or it could blow up and I won’t be held responsible. Just because these settings work for me, doesn’t mean they will for you.
