System (host) clock frequency changes were made using the BIOS screen shown in
Figure 3.6. The frequency display shows the results of increasing the system clock
setting from 100 MHz to 105 MHz with the resulting processor speed increase from
3.90 GHz to 4.09 GHz (39x105 MHz = 4.09 GHz).

Increased to 105 MHz

NOTE
The multipliers for the processor were left unchanged from the default of 39 and only
the host clock frequency was increased. Since the speeds of the other board
subsystems are derived from the host clock, the memory speed will be increased as
well. This increase may require memory setting adjustments to restore stability.
Consult Section 3.6.5 for more information on memory settings.
