• The frequency ratio of processors greater than 8x has been
locked by the manufacturer and will no longer have the
flexibility of using extended ratios. Therefore, the system will
use the processor’s factory default ratio.
Note:
• Use a PS/2 or AT (requires a DIN to mini DIN adapter)
keyboard for method 2.
• When using a 66MHz FSB processor with PC-100 SDRAM
DIMM, the system memor y clock is 3/2 of the CPU’s
external bus clock and the PCI clock is 1/2 of the CPU’s
external bus clock.
• When using a 100MHz FSB processor with PC-100
SDRAM DIMM, the system memor y clock is the same as
the CPU’s external bus clock and the PCI clock is 1/3 of
the CPU’s external bus clock.
• When using a 133MHz FSB processor with PC-100
SDRAM DIMM, the system memor y clock is 3/4 of the
CPU’s external bus clock and the PCI clock is 1/4 of the
CPU’s external bus clock.
• When using a 133MHz FSB processor with PC-133
SDRAM DIMM, the system memor y clock is the same as
the CPU’s external bus clock and the PCI clock is 1/4 of
the CPU’s external bus clock.
