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]. Memory Controller Mode This option appears only when you adopt Phenom CPU. It allows you to adjust the memory controller mode. Configuration options: [Unganged] and [Ganged]. The default value is [Unganged]. Power Down Enable Use this item to enable or disable DDR power down mode. Bank Interleaving Interleaving allows memory accesses to be spread out over banks on the same node, or accross nodes, decreasing access contention. Channel Interleaving This option appears only when you adopt Phenom CPU. It allows you to enable Channel Memory Interleaving. Configuration options: [Disabled], [XOR of Address bit [20:16, 6]], [XOR of Address bit [20:16, 9]], [Address bits 6] and [Address bits 12]. The default value is [XOR of Address bit [20:16, 6]]. CAS Latency (CL) Use this item to adjust the means of memory accessing. Configuration options: [Auto], [3CLK] to [7CLK]. The default value is [Auto]. TRCD Use this to adjust TRCD values. Configuration options: [Auto], [3CLK] to [6CLK]. The default value is [Auto]. 40
