#over_voltage	CPU/GPU core voltage adjustment. [-16,8] equates to [0.8V,1.4V] with 0.025V steps. 
#		In other words, specifying -16 will give 0.8V as the GPU/core voltage, and specifying 8 will give 1.4V. 
#		For defaults see table below. Values above 6 are only allowed when force_turbo is specified: this sets the warranty bit if over_voltage_* is also set.
#over_voltage_sdram	Sets over_voltage_sdram_c, over_voltage_sdram_i, and over_voltage_sdram_p together.
#over_voltage_sdram_c	SDRAM controller voltage adjustment. [-16,8] equates to [0.8V,1.4V] with 0.025V steps. The default value is 0 (1.2V).
#over_voltage_sdram_i	SDRAM I/O voltage adjustment. [-16,8] equates to [0.8V,1.4V] with 0.025V steps. The default value is 0 (1.2V).
#over_voltage_sdram_p	SDRAM phy voltage adjustment. [-16,8] equates to [0.8V,1.4V] with 0.025V steps. The default value is 0 (1.2V).
