DRAM Frequency [Auto]
When Congure DRAM Timing by SPD is enabled, you are not allowed to change
the setting of this item. The motherboard automatically sets the DDR operating
frequency according to the DRAM SPD. When Congure DRAM Timing by SPD
is disabled, this item allows you to set the DDR operating frequency manually.
Conguration options: [Auto] [667 MHz] [800 MHz]
Congure DRAM Timing by SPD [Enabled]
When this item is enabled, the DRAM timing parameters are set according to the
DRAM Serial Presence Detect (SPD). When disabled, you can manually set the
DRAM timing parameters through the DRAM sub-items. The following sub-items
appear when this item is disabled. Conguration options: [Disabled] [Enabled]
DRAM CAS# Latency [5]
Controls the latency between the SDRAM read command and the time the
data actually becomes available. Conguration options: [3] [4] [5] [6]
DRAM RAS# to CAS# Delay [6 DRAM Clocks]
Controls the latency between the DDR SDRAM active command and the
read/write command. Conguration options: [3 DRAM Clocks] [4 DRAM
Clocks] [5 DRAM Clocks] [6 DRAM Clocks]
DRAM RAS# Precharge [6 DRAM Clocks]
Controls the idle clocks after issuing a precharge command to the DDR
SDRAM. Conguration options: [3 DRAM Clocks] [4 DRAM Clocks] [5 DRAM
Clocks] [6 DRAM Clocks]
DRAM RAS# Activate to Precharge Delay [15 DRAM Clocks]
Conguration options: [9 DRAM Clocks] [10 DRAM Clocks] ~ [15 DRAM
Clocks]
