CPU External Frequency
FSB Strap to North Bridge [Auto]
Configuration options: [Auto] [200MHz] [266MHz] [333MHz] [400MHz]
DRAM Frequency [Auto]
Allows you to set the DDR2 operating frequency.
Configuration options: [Auto] [DDR2-667MHz] [DDR2-800MHz] [DDR2-835MHz]
[DDR2-887MHz] [DDR2-1002 MHz] [DDR2-1066MHz] [DDR2-1111MHz] [DDR2-1002 MHz] [DDR2-1066MHz] [DDR2-1111MHz]
[DDR2-*1200MHz*]
The DDR2 frequency reaches 1200 MHz after overclocking.
A very high DRAM frequency may cause the system to become unstable! If this
happens, revert to the default setting.
The configuration options may vary depending on the CPU level you select.
DRAM Command Rate [Auto]
Select [1N] to obtain better DRAM performance; select [2N] to enhance DRAM
overclocking ability. Configuration options: [Auto] [1N] [2N]
