CPU Speed [Manual]
When the motherboard is set to JumperFree™ mode, this field allows you
to select the internal speed of your CPU. Once a specific CPU speed is
selected, the correct values will be filled in for the subsequent 3 fields. Se-
lect [Manual] if you want to make changes to the subsequent 3 fields. Con-
figuration options: [Manual] [300MHz] [350MHz]...[733MHz]
CPU Core:Bus Freq. Multiple (when CPU Speed is set to [Manual])
This field is for unlocked processors only. If your socket 370 processor’s
Frequency Multiple is locked, setting the Frequency Multiple here will have
no effect. This field sets the frequency multiple between the CPU’s internal
frequency and external frequency. This must be set in conjunction with CPU
Bus Frequency to match the speed of your CPU. Configuration options:
[2.0x] [2.5x] [3.0x]...[7.0x] [7.5x] [8.0x]
CPU/SDRAM/PCI Freq. Ratio (when CPU Speed is set to [Manual])
This field determines whether the memory clock frequency is set to be in
synchronous or asynchronous mode with respect to the CPU Bus Frequency.
Each of the two memory data transfer methods leads to a set of 16 CPU Bus
Frequency selections. Configuration options: [2/3/1] [3/3/1]
CPU Bus Frequency (MHz) (when CPU Speed is set to [Manual])
This feature tells the clock generator what frequency to send to the CPU, DRAM,
and chipset. The bus frequency (external frequency) multiplied by the bus mul-
tiple equals the CPU’s internal frequency (the CPU speed). The configuration
options vary depending on the CPU/SDRAM/PCI Freqency Ratio.
