MS-7025 ATX Mainboard CAS# Latency (Tcl) This controls the CAS latency, which determines the timing delay (in clock cycles) before SDRAM starts a read command after receiving it. Settings: [Auto], [CL=2.0], [CL=2.5], [CL=3.0]. [CL=2.0] increases the system performance the most while [CL=3.0] provides the most stable performance. RAS# to CAS# delay (Trcd) When DRAM is refreshed, both rows and columns are addressed separately. This setup item allows you to determine the timing of the transition from RAS (row address strobe) to CAS (column address strobe). The less the clock cycles, the faster the DRAM performance. Setting options: [Auto], [2 Bus Clocks], [3 Bus Clocks], [4 Bus Clocks], [5 Bus Clocks], [6 Bus Clocks], [7 Bus Clocks]. Min RAS# active Time (Tras) When the DDR Timing Setting by is set to [Manual], the field is adjustable. This setting determines the time RAS takes to read from and write to a memory cell. Setting options: [Auto], [5 Bus Clocks], [6 Bus Clocks], [7 Bus Clocks], [8 Bus Clocks], [9 Bus Clocks], [10 Bus Clocks], [11 Bus Clocks], [12 Bus Clocks], [13 Bus Clocks], [14 Bus Clocks], [15 Bus Clocks]. Row Precharge Time (Trp) This item controls the number of cycles for Row Address Strobe (RAS) to be allowed to precharge. If insufficient time is allowed for the RAS to accumulate its charge before DRAM refresh, refreshing may be incomplete and DRAM may fail to retain data. This item applies only when synchronous DRAM is installed in the system. Available settings: [Auto], [2 Bus Clocks], [3 Bus Clocks], [4 Bus Clocks], [5 Bus Clocks], [6 Bus Clocks]. High Performance Mode This field allows you to select the DDR timing setting. Setting to [Optimized] enables Adjust DDR Memory Frequency automatically to be determined by SPD. Selecting [Manual] allows users to configure these fields manually. Setting options: [Optimized], [Manual]. Aggressive Timing This item allows you to enable or disable the memory clock. When [Enabled] is selected, the timing delay of memory will be shorten to increase the performance. Setting options: [Enabled], [Disabled]. Dynamic Overclocking Dynamic Overclocking Technology is the automatic overclocking function, included in the MSITM's newly developed CoreCellTM Technology. It is designed to detect the load balance of CPU while running programs, and to adjust the best CPU frequency automatically. When the motherboard detects CPU is running programs, it will speed up CPU automatically to make the program run smoothly and faster. When the CPU is temporarily suspending or staying in the low load balance, it will restore the default settings instead. Usually the Dynamic Overclocking Technology will be powered only when users' PC need to run huge amount of data like 3D games or the video process, and the CPU frequency need to be boosted up to enhance the overall performance. 3-24
