CPU FSB frequency will be 34.5MHz x 4 =138MHz.
The SDRAM working frequency will be 34.5MHz x 3 =103.5MHz.
And the PCI bus working frequency will be 34.5MHz x 1 = 34.5MHz.
Giving you all the proper values (within a few MHz or so, its
never exactly precise.)
ABIT patented technology, SoftMenu™ allows you to adjust the FSB working
frequency, when you adjust the working frequency, please choose the proper values
for the FSB : SDRAM : PCI for your CPU. For example:
A CPU rated for 66MHz FSB ( such as Celeron
66MHz (2:3:1) (each divided by 2): 66MHz : 100MHz : 33MHz
or a CPU rated for 100MHz FSB (such as Pentium
PGA)
100MHz (3:3:1) (each divided by 3) 100MHz : 100MHz : 33MHz
or a CPU rated for 133MHz FSB (such as a Pentium
FC-PGA)
133MHz (4:3:1) (each divided by 4) 133MHz : 100MHz : 33MHz
Note: the various components and their corresponding "bus speeds" should still
work fine, nonetheless going too far "out of spec" may cause system damage
or malfunction. System performance will depend mainly on the quality of the
components used.
CPU bus speed above 66MHz/100MHz/133MHz supported but not guaranteed due to
the PCI and chipset specs.
Multiplier Factor:
You can choose from the following multiplier factors:
2.0
6.5
11.0
However, differences will exist because of the various brands and types available.
