Galaxy S2, Cyanogenmod 10, SiyahKernel and ExTweaks

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
  • mDNIe Negative Toggle = Disabled
  • LED Timeout = Use ROM defaults (disabled)
  • LED Fade Out = no
  • LED On With Touch = no
  • LED Voltage Level = 2700mV
  • 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.
