After checking the manual, I managed to find the following:
I'm guessing this is the "C6" you're referring to:
1) RC6(Render Standby)
Allows you to determine whether to let the onboard graphics enter standby mode to decrease power
consumption. (Default: Enabled) - This will be disabled provided you were referring to this
2) CPU EIST Function
Enables or disables Enhanced Intel SpeedStep Technology (EIST). Depending on CPU loading, Intel EIST technology can dynamically and effectively lower the CPU voltage and core frequency to decrease average power consumption and heat production. Auto lets the BIOS automatically configure this setting.
(Default: Auto) - This will be disabled
3) CPU Enhanced Halt (C1E)
Enables or disables Intel CPU Enhanced Halt (C1E) function, a CPU power-saving function in system halt state. When enabled, the CPU core frequency and voltage will be reduced during system halt state to
decrease power consumption. Auto lets the BIOS automatically configure this setting. (Default: Auto) - What should this be set to?
4) C3/C6 State Support
Allows you to determine whether to let the CPU enter C3/C6 mode in system halt state. When enabled, the
CPU core frequency and voltage will be reduced during system halt state to decrease power consumption.
The C3/C6 state is a more enhanced power-saving state than C1. Auto lets the BIOS automatically configure this setting. (Default: Auto) - Should I set this to C3 or Off?
