OC Genie Button Operation This field is used to enable disable OC Genie function DRAM Ratio This setting controls the ratio of memory frequency to enable the memory to run at different frequency combinations Adjusted DRAM Frequency It shows the adjusted DRAM frequency Read only DRAM Timing Mode Select whether DRAM timing is controlled by the SPD Serial Presence Detect EEPROM on the DRAM module Setting to Auto enables DRAM timings and the following Advanced DRAM Configuration sub menu to be determined by BIOS based on the configurations on the SPD Selecting Manual allows users to con figure the DRAM timings and the following related Advanced DRAM Configura tion sub menu manually Advanced DRAM Configuration Press Enter to enter the sub menu In this sub menu you can adjust the ad vanced DRAM timing Command Rate This setting controls the DRAM command rate tCL This controls the CAS latency which determines the timing delay in clock cycles before SDRAM starts a read command after receiving it 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 cy cles the faster the DRAM performance tRP This setting 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 tRAS This setting determines the time RAS takes to read from and write to memory cell tRFC This setting determines the time RFC takes to read from and write to a memory cell tWR Minimum time interval between end of write data burst and the start of a pre charge command Allows sense amplifiers to restore data to cells
