Service [Q] r394 franco kernel (help voltage setup and volume boost)

Hi guys I need some help regarding with voltage, can someone tell me whats the finest set up for voltage of CPU and GPU? My current set up is

CPU freq. 1536 MHz
Voltage 1325 mV

GPU freq. 512 MHz
Voltage 1200 mV

Usually when I play NBA 2k14, my phone start to gain to much heat then the games starts to flick after a few more seconds it will automatically shutdown.

In addition, I have a problem with volume boost, it seems that it doesn't work even if I change the volume level (franco kernel updater) Since I'm new here I can't post anything in Development section.

Thanks In advance
