Operating Frequency Setting [User Define]
When the motherboard is set to JumperFree™ mode, this field allows you
to configure the external frequency of your CPU. Select [User Define] if
you want to make changes to the
CPU Frequency
field. When [Standard]
is selected,
CPU
(external)
Frequency
will be fixed at 100MHz. Configu-
ration options: [Standard] [User Define]
CPU Frequency (if Operating Frequency is set to [User Define])
This feature tells the clock generator which frequency to send to the system
bus and PCI bus.
The bus frequency (external frequency0 multiplied by the
bus frequency equals the CPU speed (the CPU’s internal frequency). Note
that selecting a frequency higher than what the CPU manufacturer
recommends may cause the system to hang or crash.
See
System Hangup
later in this section.
DRAM Frequency
This field determines whether the memory clock frequency is set to be in
synchronous or asynchronous mode with respect to the
CPU Frequency
.
This must be set in conjunction with
CPU
(external)
Frequency
to match
the speed of your SDRAM. When you press <Enter> on this field, the first
available option in the pop-up menu equals the CPU Frequency you select
for the previous field, and the second available option is the CPU Frequency
multiplied by 4/3.
To maintain and ensure system stability
,
DRAM Fre-
quency
is set to [100 MHz] when the BIOS setup default settings are loaded/
selected.
