The following item appears only when the AI Overclocking item is set to [AI N.O.S.] or [Manual].

Memory Voltage [Auto]

Allows selection of the DDR SDRAM operating voltage. Set to Auto for safe mode. Configuration options: [2.60V] [2.70V] [2.80V] [2.90V] [Auto]

Refer to the DDR documentation before setting the memory voltage. Setting a very high memory voltage may damage the memory module(s)!

Chipset Core Voltage [Auto]

Allows selection of the chipset core voltage.

Configuration options: [1.50V] [1.60V] [Auto]

CPU VCore Voltage [Auto]

Allows selection of the CPU VCore voltage. The configuration options vary depending on the CPU installed. Setting to Auto allows the BIOS to detect the VCore voltage of the CPU installed.

Refer to the CPU documentation before setting the CPU VCore voltage. A very high Vcore voltage can severely damage the CPU!

FSB Termination Voltage [Auto]

Sets the Front Side Bus (FSB) termination voltage.

Configuration options: [1.20V] [1.40V] [Auto]

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. Refer to the following table for the correct Front Side Bus and CPU External Frequency settings. Use the <+> and <-> keys to adjust the value.

Table 4.4.2 FSB/CPU External Frequency Synchronization

 

Front Side Bus

CPU External Frequency

 

FSB 800

200 MHz

 

 

 

 

FSB 533

133 MHz

 

 

 

 

FSB 400

100 MHz

Selecting a very high CPU frequency may cause the system to become unstable! If this happens, revert to the default setting.
