DRAM Frequency [Auto]
Allows you to set the DDR2 operating frequency.
Configuration options: [Auto] [DDR2-400MHz] [DDR2-533MHz] [DDR-667MHz]
Selecting a very high DRAM frequency may cause the system to become
unstable! If this happens, revert to the default setting.
The following item appears only when you set the
AI Overclocking
item to
[Manual].
CPU Frequency [XXX]
Displays the frequency sent by the clock generator to the system bus and PCI bus.
The value of this item is auto-detected by the BIOS. Use the
<+>
and
<->
keys to
adjust the CPU frequency. You can also type the desired CPU frequency using the
numeric keypad. The values range from 100 to 400. Refer to the table below for
the correct Front Side Bus and CPU External Frequency settings.
PCI Express Frequency [Auto]
Allows you to set the PCI Express frequency. This item is set to [Auto] by default.
Configuration options: [Auto] [90]...[150]
PCI Clock Synchronization Mode [To PCI Express]
Allows you to synchronize the PCI frequency with the PCI Express or CPU
frequency. Configuration options: [To PCI Express] [ Fixed 33.3MHz]
[Fixed 36.3MHz] [Fixed 40.0MHz]
Memory Voltage [Auto]
Allows you to select the DDR2 reference voltage.
Configuration options: [Auto] [1.812V] [1.904V]
Refer to the DDR2 documentation before adjusting the memory voltage. Setting a
very high memory voltage may damage the memory module(s)!
