Memory Frequency
Enables you to select a ratio of the Double Data Rate Synchronous DRAM to match
the installed DRAM frequency 266/333/400MHz. We recommend that you leave this
item at the default value.
When the FSB is 400MHz the options will display 3:4 =>DDR266.
When the FSB is 533MHz the options will display 1:1 =>DDR266, 4:5 =>DDR333 and
Auto =>DDR333 (by SPD).
When the FSB is 800MHz the options will display 1:1=>DDR400, 5:4=>DDR320 and
Auto=>DDR320 (by SPD).
CPU Clock Ratio
Use this item to select a multiplier for the system front side bus (FSB) frequency.
The value of the multiplier must be set so that:
Multiplier x Front side Bus Frequency = CPU Clock Speed
For example, if you have a processor that is rated to run at 800 MHz and the
system is running a front side bus frequency of 100 MHz, you should select a
multiplier of 8 so that:
8 (Multiplier) x 100 MHz (front side bus) = 800 MHz (CPU clock)
Key in the DEC (decimalism) number for the CPU Clock Ratio.
