3.5.5.2 Memory Performance Options
The Memory Configuration BIOS page contains all the memory timing options that can
be adjusted.
NOTE
For each of the timings, except the multipliers, lower number settings correspond with
higher performance and potential memory system instability.

3.5.5.3 Determining Memory Frequency
Increasing the host clock frequency will increase the memory speed, in addition to the
processor frequency. Note that the memory is not run directly from the host clock.
The memory clock frequency is generated by the processor using input from the host
clock signal received from the Intel P67 PCH. The default memory clock frequency
runs at 133.3 MHz. Increasing the system clock frequency affects the memory
frequency according to the following formula:
Memory frequency = (memory multiplier) * (percent increase in host clock) *
(133.3 MHz)
