[. . . ] The parameter can be adjusted from 0~127. Higher parameter means faster CPU fan speed. (Default parameter: 80) The CPU fan runs at full speed when both CPU Smart FAN Control and CPU FAN Manual Control are disabled. (Note) Whether the CPU Smart FAN Control function is supported will depend on the CPU you install. For more detailed information please check at the FAQ section on GIGABYTE's website. - 47 BIOS Setup English Temp of FAN turn off (Default temperature: 0oC) When the CPU temperature is below the value set in this option, the CPU fan will stop spinning. Temp Limit of Low Speed (Default temperature: 20oC) The CPU fan will stop spinning when the CPU temperature is below the value set in Temp of FAN turn off option. The CPU fan will start to spin again with the parameter set in CPU FAN: Low Speed when the CPU temperature exceeds the value set in Temp Limit of Low Speed. Temp Limit of Mid Speed (Default temperature: 50oC) When the CPU temperature exceeds the value set in this option, the CPU fan spins with the parameter specified in CPU FAN: Mid Speed. For example, by default, when the CPU temperature exceeds 50 o C, CPU fan runs with parameter 12. Temp Limit of High Speed (Default temperature: 60oC) When the CPU temperature exceeds the value set in this option, the CPU fan rotates with the parameter specified in CPU FAN: High Speed. For example, by default, when the CPU temperature exceeds 60 o C, CPU fan runs with parameter 80. Temp of full FAN Speed (Default temperature: 70oC) When the CPU temperature exceeds the value set in this option, the CPU fan runs at full speed.

K8 CPU Clock Ratio This setup option will automatically assign by CPU detection. The option will display "Locked" and read only or will not show up if the CPU ratio is not changeable. - 49 BIOS Setup English Current DDR Speed Displays the current DDR speed. DDR clock/Timing Mode Auto Manual Set DDR Clock and Timing Mode automatically. (Default value) Set DDR Clock and Timing Mode manually. CPU/DDR clock Ratio Set the CPU/DDR clock ratio. Options include 2/1, 2/1. 33, 2/1. 5, 2/1. 66, 2/1. 83, 2/2. DDR Speed This item changes according to the value set in CPU/DDR clock Ratio. DDR Timing Auto Manual BIOS will automatically set up the DDR Timing by DRAM SPD data. (Default value) This item allows user to set DDR Timing manually. Set CAS Latency to1. 5/2/2. 5/3 (Default value:2. 5) BIOS will automatically detect the minimum RAS Active Time. Set the minimum RAS Active Time to 5T~15T (Default value:6T) Set DRAM RAS to CAS Delay to 2T/3T/4T/5T/6T/7T. (Default value:3T) BIOS will automatically detect the Row Precharge Time. Set the Row Precharge Time to 2T/3T/4T/5T/6T/7T. (Default value:3T) BIOS will automatically detect the Row to Row delay. (Default value:2T) Set Row Cycle Time to 7T~22T.
