(2) CPU Frequency
Available [CPU Frequency] settings on your SY-6BA+ IV Motherboard
are detailed in the following table.
CPU Frequency (MHz)
Manual 350MHz (100 x 3.5)
266MHz (66 x 4 ) 400MHz (100 x 4 )
300MHz (66 x 4.5) 450MHz (100 x 4.5)
333MHz (66 x 5 ) 500MHz (100 x 5 )
366MHz (66 x 5.5) 550MHz (100 x 5.5)
400MHz (66 x 6 ) 600MHz (100 x 6 )
433MHz (66 x 6. 5) 650MHz (100 x 6.5)
466MHz ( 66 x 7 ) 700MHz (100 x 7 )
500MHz ( 66 x 7.5)
Select the working frequency of
your Pentium
®
III, Pentium
®
II,
Celeron processor among these
preset values.
Note: Mark the checkbox that
corresponds to the working
frequency of your Pentium
®
III,
Pentium
®
II, Celeron processor
in case the CMOS configuration
should be lost.
If you set this field to [Manual], you are then required to fill in the next
two consecutive fields: (a) the CPU Host/PCI Clock, and (b) the CPU
Ratio.
(a) CPU Host/PCI Clock
CPU Host / PCI Clock
o66/33 o95/31 o115/38 o124/41 o140/35
o75/37 o100/33 o117/39 o126/31 o142/35
o78/39 o105/35 o118/39 o133/33 o144/36
o81/40 o110/36 o120/40 o135/33 o150/37
o83/40 o112/37 o122/37 o137/34 o155/38
o90/30 o113/37 o124/31 o138/34
Under this item you find the
frequencies your PCI and AGP
slots run at. These frequencies
are derived from the CPU host
clock in the following way:
CPU host clock > 100MHz
PCI = CPU host clock /3,
CPU host clock < 100MHz
PCI = CPU host clock /2,
(b) CPU Ratio
After you have selected the CPU Host/ PCI Clock, choose the right
multiplier for the CPU. CPU Ratio options are:
o x 2 o x 2.5 o x 3 o x 3.5 o x 4
o x 4.5 o x 5 o x 5.5 o x 6 o x 6.5
o x 7 o x 7.5 o x 8
The CPU frequency is then defined as [host clock freq.] x [multiplier], and
should the working frequency of your CPUs processor.
