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.
System Performance
This item will help you to configure your system performance.
Options: Optimal, Aggressive, Turbo, Expert.
CPU Clock Ratio
Use this item to select a multiplier for the system frontside bus (FSB) frequency. The
value of the multiplier must be set so that:
Multiplier x Frontside Bus Frequency = CPU Clock Speed
For example, if you have a processor that is rated to run at 450 MHz and the
system is running a frontside bus frequency of 100 MHz, you should select a
multiplier of 4.5 so that:
4.5 (Multiplier) x 100 MHz (frontside bus) = 450 MHz (CPU clock)
FSB Frequency
Enables you to set the CPU frontside bus speed. Enables you to subtle tuning FSB.
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.
