Chapter 2: BIOS setup
DDR Voltage [Auto]
Allows selection of the DDR SDRAM operating voltage. Set to Auto for safe
mode.
Configuration options: [Auto] [2.50V] [2.60V] [2.70V] [2.80V]
Refer to the DDR documentation before setting the memory voltage.
Setting a very high memory voltage may damage the memory module(s)!
The following item appears only when the AI Overclocking item is set to
[Manual].
Memory Clock Mode [Auto]
Allows you to set the memory clock mode.
Configuration options: [Auto] [Sync to CPU] [Async Manual Mode]
Memory Frequency [300]
Allows you to set the memory frequency. This item appears only when the
Memory Clock Mode item is set to [Async Manual Mode].
Configuration options: [100] ~ [300]
Selecting a very high CPU frequency may cause the system to become
unstable! If this happens, revert to the default setting.
CPU Frequency [XXX] (value is auto-detected)
Indicates the frequency sent by the clock generator to the system bus
and PCI bus. The bus frequency (external frequency) multiplied by the bus
multiple equals the CPU speed. The value of this item is auto-detected by
BIOS. The values range from 100 to 400. Use the <+> and <-> keys to
adjust the value.
Overclock Options [Overclock 5%]
Allows you to set the oveclocking options.
Configuration options: [Overclock 5%] [Overclock 10%] [Overclock 15%]
