Flashing Boeffla Kernel 4.0(Latest) for Max Performance on Samsung S3

This article is a follow up of my previous post on How to upgrade Samsung S3 I9300 with CM 12.1(Lollipop 5.1.1) and flash Boeffla Kernel 4.0

*NOTE 1 :- I HIGHLY DISCOURAGE INSTALLING OF G-APPS, IT WILL LAG YOUR PHONE TO ITS END.IF YOU ARE FOND OF PLAYSTORE, THEN I PREFER UNINSTALLING EVERY GOOGLE APPS OTHER THAN PLAYSTORE OR SOME MANDATORY APPS LIKE YOUTUBE OR GMAIL.

*NOTE 2 :- BOEFFLA KERNEL FOR CM 12.1 IS STILL ALPHA AND IT HAD REACHED ITS EOL(END OF LIFE).

No more NOTES :D.For real, after flashing both ROM and Boeffla, I am getting high performance compared to previous CM versions and it is pretty stable, and can be used as a daily driver.

• Move to http://www.boeffla-kernel.de/index.php/downloads-samsung-phones and select the appropriate version by scrolling down, as shown below.

• After downloading the latest zip file, move it to your phone and reboot to custom recovery CWM or TWRP or PHILZ, that you have installed in your phone.
• Just flash the copied zip file using "Install zip from sdcard".
• Now reboot.(It may take some time to boot up, as the kernel changed).
• Voila!!!You got Boeffla latest kernel for S3, running flawlessly.

Tweaks to boost your phone to 40-50% faster.

• After installing the Boeffla Config V2.apk ,click open the application from the app drawer.
• Give root permissions to the application if you are notified to give.
• The below picture shows ma phone's overview through the config application.

• Now select CPU section and adjust the frequencies and tweaks as shown in the below picture.As you can see ,it will boost your phone to its max by squeezing your processor speed from 1.4 Ghz to 1.7 Ghz.

• Now here comes the real tweak for gamers.Select the GPU section.And set the values as shown in the below picture.You may get bugged or get random reboots,if then just reduce the values correspondingly until your phone seems stable.But for me the below values are good and ma graphics processing works at its max..

• Its better for you to give an overvolt +50 mV to your GPU for stability like below picture.

• Now go to the Governor/IO section and select a governor shown as in the below picture.I prefer you to try every governors and select the best one for you.For me ,my phone seems good with "pegausq" governor.

Some other miscellaneous tweaks

• As you know ,generally samsung's every mobile phones or tablets out in the market got low sound volume but got better quality audio.By tweaking the sound part of the kernel ,you can achieve above 80% of the current stock volume.You may adjust the sound on your own ,my preference is shown in below picture.

• Configure some other miscellaneous tweaks like in the pictures below.

You could also read my bench mark result after flashing the above kernel. Wow Samsung S3 with 30084(impossible) as score from AnTuTu benchmark testing.
