MS-7511 Mainboard Adjust CPU FSB Frequency This item allows you to select the CPU Front Side Bus clock frequency (in MHz). Adjust CPU Ratio This item is used to adjust CPU clock multiplier (ratio). It is available only when the processor supports this function. Advance DRAM Configuration Press to enter the sub-menu and the following screen appears. DRAM Timing Mode This field has the capacity to automatically detect all of the DRAM timing. If you set this field to [Manual], some fields will appear and selectable. tRC W hen the DRAM Timing M ode sets to [Manual], the field is adjustable. The rowcycle time determines the minimum number of clock cycles a memory row takesto complete a full cycle, from row activation up to the precharging of the ac t i ver ow . tRRD W hen the DRAM Timing Mode sets to [Manual], the field is adjustable. Specifies the active-to-active delay of different banks. Time interval between a read and a precharge command. tRCD W hen the DRAM Timing Mode sets to [Manual], the field is adjustable. W hen 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. CAS# Latency (CL) W hen the DRAM Timing Mode sets to [Manual], the field is adjustable. This controls the CAS latency, which determines the timing delay (in clock cycles) before SDRAM starts a read command after receiving it. tRAS W hen the DRAM Timing Mode sets to [Manual], this field is adjustable. This setting determines the time RAS takes to read from and write to memory cell. tRP W hen the DRAM Timing Mode sets to [Manual], this field is adjustable. This setting controls the number of cycles for Row Address Strobe (RAS) to be 3-20
