CPU Frequency Multiplier This option appears only when you adopt Phenom CPU. However, for safety and system stability, it is not recommended to adjust the value of this item. NB Frequency Multiplier This option appears only when you adopt Phenom CPU. However, for safety and system stability, it is not recommended to adjust the value of this item. Memory Clock This item can be set by the code using [Auto]. You can set one of the standard values as listed: [200MHz (DDRII400)], [266MHz (DDRII533)], [333MHz (DDRII667)] and [400MHz (DDRII800)]. If you adopt Phenom CPU, there is one more option: [533MHz (DDRII1066)]. Flexibility Option The default value of this option is [Disabled]. It will allow better tolerance for memory compatibility when it is set to [Enabled]. CAS Latency (CL) Use this item to adjust the means of memory accessing. Configuration options: [Auto], [3CLK], [4CLK], [5CLK] and [6CLK]. The default value is [Auto]. TRCD Use this to adjust TRCD values. Configuration options: [Auto], [3CLK], [4CLK], [5CLK] and [6CLK]. The default value is [Auto]. TRP Use this to adjust TRP values. Configuration options: [Auto], [3CLK], [4CLK], [5CLK] and [6CLK]. The default value is [Auto]. TRTP Use this to adjust TRTP values. Configuration options: [Auto], [2-4CLK] and [3-5CLK]. The default value is [Auto]. TRAS Use this to adjust TRAS values. Configuration options: [Auto], [5CLK] to [18CLK]. The default value is [Auto]. TRRD Use this to adjust TRRD values. Configuration options: [Auto], [2CLK], [3CLK], [4CLK] and [5CLK]. The default value is [Auto]. TRC Use this to adjust TRC values. Configuration options: [11CLK] to [26CLK]. The default value is [Auto]. TWR Use this to adjust TWR values. Configuration options: [Auto], [3CLK], [4CLK], [5CLK] and [6CLK]. The default value is [Auto]. 37
