DRAM Frequency [Auto] Allows you to set the DDR operating frequency. Configuration options: [Auto] [533 MHz] [667 Mhz] Configure DRAM Timing by SPD [Enabled] When this item is enabled, the DRAM timing parameters are set according to the DRAM SPD (Serial Presence Detect). 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. Configuration options: [Disabled] [Enabled] DRAM CAS# Latency [5 Clocks] Controls the latency between the SDRAM read command and the time the data actually becomes available. Configuration options: [5] [4] [3] DRAM RAS# to CAS# Delay [6 DRAM Clocks] Controls the latency between the DDR SDRAM active command and the read/write command. Configuration options: [2 DRAM Clocks] [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. Configuration options: [2 DRAM Clocks] [3 DRAM Clocks] [4 DRAM Clocks] [5 DRAM Clocks] [6 DRAM Clocks] DRAM RAS# Activate to Precharge [15 DRAM Clocks] Configuration options: [4 DRAM Clocks] [5 DRAM Clocks] ~ [15 DRAM Clocks] Boots Graphic Adapter Priority [PEG/PCI] Allows selection of the graphics controller to use as primary boot device. Configuration options: [PCI/PEG] [PEG/PCI] PEG Port Configuration PEG Port [Auto] Allows you to set or disable the PCI Express Graphic port.
