Memory Remap Feature Use this item to enable or disable memory remap feature. Configuration options: [Enabled] and [Disabled]. The default value is [Disabled]. DRAM Frequency If [Auto] is selected, the motherboard will detect the memory module(s) inserted and assigns appropriate frequency automatically. You may select [333MHz (DDR2 667)], [400MHz (DDR2 800)] or [533MHz (DDR2 1066)] for DDR2 memory modules, or select [400MHz (DDR3 800)], [533MHz (DDR3 1066)], [667MHz (DDR3 1333)] or [800MHz (DDR3 1600)] for DDR3 memory modules. The configuration options depend on the CPU and memory module you adopt on this motherboard. Please refer to page 8 for the CPU FSB frequency and its corresponding memory support frequency. Flexibility Option The default value of this option is [Disabled]. It will allow better tolerance for memory compatibility when it is set to [Enabled]. DRAM tCL Use this item to adjust the means of memory accessing. Configuration options for DDR2 memory modules are [3], [4], [5], [6] and [Auto]. Configuration options for DDR3 memory modules are are [5], [6], [7], [8], [9], [10], [11] and [Auto]. DRAM tRCD This controls the latency between the DRAM active command and the read / write command. Configuration options: [Auto], [3 DRAM Clocks] to [15 DRAM Clocks]. DRAM tRP This controls the idle clocks after a precharge command is issued. Configuration options: [Auto], [3 DRAM Clocks] to [15 DRAM Clocks]. 57
