Custom Kernel for the Nexus 7 Brings Huge Performance Boost

One of the biggest advantages of owning an Android device is having the ability to customize not only the interface, but the system settings itself. Part of that includes flashing a custom kernel, which can bring all sorts of enhancements to a variety of levels. Such settings include specifying voltages, underclock or overclock speeds of the CPU, custom color settings. You get the idea.

XDA Senior member clemsyn has created a modified kernel for the Nexus 7 called the Elite Kernel, which is a modified version of the Motley kernel originally created by XDA Senior Member _motley. Hit the break for the list of tweaks this customized kernel brings.

  • JRCU is implemented
  • Lowest backlight setting set to 5 (save battery and better reading at night, if you have screen flicker issue it will be more noticable because of this so I suggest covering the ground pin of wifi)
  • Core voltage increased from 1200 to 1250mv on the high side to hit 1.7 frequency and 600 GPU but decreased from 950 to 900mv on the low side.
  • Increased CPU voltage to 1240mv for 1.7 frequency but allows decreased 750mv in low side
  • Increased GPU clock to 600 and pixclock increased (please let me know if you have problems on screen due to pixclock increase but so far no issues on testers)
  • Built using gcc 4.5.2 ( I know, I’m an oldie)
  • DVFS core table completely changed to allow max clock of host1x and pll_c and hit most max frequencies.
  • Enable Thermal_Sys to throttle at 68 (BTW, if you are using system tuner, the reading is +10 as per secret)

The enhancements seem to be geared towards gaming, so if you love gaming on your Nexus, especially titles such as Dead Trigger, then this modification may be for you. It should be noted that not all Nexus 7 tablets will be able to handle this kernel due to the aggressive lowering of voltages. If you want to give this a try, we recommend taking a Nandroid backup before attempting any modification of this sort. Hit the source link for more information.

Happy Modding!
