2-18 Chapter 2: BIOS information
DDR Reference Voltage [Auto]
Allows selection of the DDR SDRAM operating voltage.
Configuration options: [2.85V] [2.75V] [2.65V] [2.55V] [Auto]
AGP VDDQ voltage [Auto]
Allows selection of the AGP operating voltage.
Configuration options: [1.80V] [1.70V] [1.60V] [1.50V] [Auto]
Refer to the CPU documentation before setting the CPU VCore voltage. A very
high Vcore voltage may severely damage the CPU!
Selecting a very high AGP/PCI frequency may cause the system to become
unstable! If this happens, revert to the default setting.
CPU VCore Voltage [Auto]
Allows you to select a specific CPU VCore voltage.
Configuration options: [Auto] [1.9500V] [1.9250V] [1.9000V] [1.8750V] [1.8500V]
[1.8250V] [1.8000V] [1.7750] [1.7500V] [1.7250V] [1.7000V] [1.6750V] [1.6500V]
[1.6250V] [1.6000V]
DRAM Frequency [Auto]
Allows you to set the DDR operating frequency depending on the CPU installed.
Configuration options: [266 MHz] [Auto]: for FSB 400 CPU, [333 MHz] [266MHz]
[Auto]: for FSB 533 CPU, [400 MHz] [333 MHz] [266 MHz] [Auto]: for FSB 800
CPU.
AGP/PCI Frequency (MHz) [Auto]
Allows you to adjust to a higher AGP/PCI frequency for better system performance
and overclocking capability. Configuration options: [Auto] [66.66/33.33]
[72.73/36.36] [80.00/40.00]
Refer to the AGP/DDR documentation before setting the AGP or DDR voltage. A
very high Vcore voltage may severely damage the AGP card, DDR DIMM
modules or chipset!
