For try1, check
1. it can boot or not
2. if it can boot, will it force reboot when screen off

How is screen off.
Will it reboot everytimes screening off
Voltage table for overclocking is depending on device chip.
You may have to tune it by any systools or editing init.qcom.post_boot.sh (simply +25mV for each step)

governor and cpu hotplug policy tweaked for battery and performace balance
Under default setting, cpu might not fullload during benchmark
if you want to benchmark, set governor: performance

Hi, @lyfkevin!
how can i OC GPU? Can you give me some detail?
I notice that GPU performance is not good as ICS stock rom

check #2 post
also u can use
fauxclock, kernel tuner etc.

hungnguyen490 · Apr 15, 2013

thank you!
if i want to oc gpu frequency in 3d, i have to do some steps like:

adb shell

su

cat /proc/kmsg | grep 'echo 320000000 > /sys/devices/platform/kgsl-3d0.0/kgsl/kgsl-3d0/max_gpuclk'

Right?

mrTechnoy · Apr 18, 2013

is it normal?

It is laggy in my end. Do I need to change something for it to fully work or what? I am new to using different kernels for phone so I am sorry.

It rebooted 1 time when downloading kernel tuner in playstore

sixline · Apr 19, 2013

Kernel works well and I am using it with tdmcode's aokp rom. It rebooted at 1st just after lockscreen appears but never again. I don' have any issues, its smooth.
