Gigabyte GA-8S661FXM-775 CPU Smart FAN Mode, Configure Dram Timing, CAS Latency Setting

English

CPU Smart FAN Mode

This option is available only when CPU Smart FAN Control is enabled.

Auto	BIOS autodetects the type of CPU fan you installed and sets the optimal CPU
	Smart FAN control mode for it. (Default Value)
Voltage	Set to Voltage when you use a CPU fan with a 3-pin fan power cable.
PWM	Set to PWM when you use a CPU fan with a 4-pin fan power cable.

In fact, the Voltage option can be used for CPU fans with 3-pin or 4-pin power cables. However, some 4-pin CPU fan power cables are not designed following Intel 4-wire fans PWM control specifications. With such CPU fans, selecting PWM will not effectively reduce the fan speed.

Configure DRAM Timing

Auto	BIOS will automatically set up the DRAM Timing by DRAM SPD data.
	(Default value)
Manual	This item allows user to set DRAM Timing manually.

CAS Latency Setting

2T/2.5T/3T	Set CAS Latency to 2T/2.5T/3T (Default value is 3T).
Auto	BIOS will automatically detect CAS Latency.
