System Performance
This item will help you to configure your system performance, selecting higher
performance may cause instability.
Options: Optimal, Aggressive, Turbo, Expert.
CPU Clock Ratio
Use this item to select a multiplier to set the CPU frequency. See FSB Frequency
item below for explanation.
FSB Frequency
Enables you to increment the CPU’s clock generator at 1 MHz step. This works
together with CPU Clock Ratio (above) to set the CPU operating frequency.
CPU Clock Generator x CPU Clock Ratio = CPU Frequency
For example, if you have a processor that is rated at 2.4GHz and the clock generator
is 200MHz, then 200MHz x 12 = 2.4GHz
Note: Overclocking failure will cause no display on the monitor. To overcome
this switch off the power supply and switch on again. Restart the
system, press and hold <Insert> key. This will revert the BIOS to default
or initial setting.
CPU Interface
Allows you to set CPU/FSB parameters for CPU most stable or overclocked.
Options: Optimal, Aggressive.
Memory Frequency
Enables you to select the memory frequency.
Options: By SPD, 50%, 60%, 66%, 75%, 80%, 83%, 100%, 120%, 125%, 133%, 150%,
166%, 200%, Auto.
Below is a list of Auto mode table for reference.

Note: Auto mode ensures the
memory init module
initializes the memory
controller for the best
performance based on the
FSB and DDR SPD
capabilities.
