CPU Voltage This option appears only when you adopt Phenom CPU. It allows you to adjust the value of CPU voltage. 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. NB Voltage This option appears only when you adopt Phenom CPU. It allows you to adjust the value of NB voltage. 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: [200 MHz (DDR2 400)], [266 MHz (DDR2 533)], [333 MHz (DDR2 667)] and [400MHz (DDR2 800)]. If you adopt Phenom CPU, there is one more option: [533MHz (DDR2 1066)] 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 [25CLK]. The default value is [Auto]. 49
