4.4 Advanced Menu
CPU Speed [Manual]
When the motherboard is set to JumperFree™ mode, this field allows you
to select the internal frequency of the CPU. Select [Manual] if you want to
make changes to the two subsequent fields. Note that selecting a
frequency higher than the CPU manufacturer recommends may cause the
system to hang or crash.
The item CPU Frequency Multiple is accessible only if you have an
unlocked processor. If your processor frequency multiple is locked, you
cannot change the setting of this item.
CPU Frequency Multiple (when CPU Speed is set to [Manual])
This field sets the frequency multiple between the CPU’s internal
frequency (CPU speed) and external frequency. Set this field in
conjunction with CPU Frequency (MHz) to match the speed of the CPU.
System memory can only operate at a frequency higher than or equal
to the CPU front side bus frequency. Refer to Table 1.4.2 “FSB/DDR
Support Table” on page 1-8 for more information.
