Settings: [By SPD, 100 MHz, 133 MHz, 166 MHz, 200MHz, 266MHz] DRAM Timing The value in this field depends on the memory modules installed in your system. Changing the value from the factory setting is not recommended unless you install new memory that has a different performance rating than the original modules. Settings: [Manual, Auto By SPD, Turbo, Ultra] SDRAM CAS Latency [DDR/DDR2] This item is for setting the speed it takes for the memory module to complete a command. Generally, a lower setting will improve the performance of your system. However, if your system becomes less stable, you should change it to a higher setting. This field is only available when "DRAM Timing" is set to "Manual". Settings: [1.5/2, 2/3, 2.5/4, 3/5] 54
