SOYO SY-6BA+ III manual CPU Host/PCI Clock, CPU Ratio, AGP Clock

Hardware Setup					SY-6BA+ III
(a) CPU Host/PCI Clock
	CPU Host / PCI Clock				Under this item you find the
					frequencies your PCI and
o66/33	o95/31	o115/38	o124/41	o140/35
					AGP slots run at. These
o75/37	o100/33	o117/39	o126/31	o142/35	frequencies are derived
					from the CPU host clock in
o78/39	o105/35	o118/39	o133/33	o144/36
					the following way:
o81/40	o110/36	o120/40	o135/33	o150/37	CPU host clock > 100MHz
					PCI = CPU host clock /3,
o83/40	o112/37	o122/37	o137/34	o155/38
					CPU host clock < 100MHz
o90/30	o113/37	o124/31	o138/34
					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.

(c) AGP Clock

This option allows you to manually adjust the AGP host bus clock frequency to a value determined as a fraction of the CPU host clock. For example:

With a CPU front side bus of 100MHz,

[Auto] sets à When [auto] is selected and the (FSB Frequency) is less then 100MHz, it will be divided by [/ 1]. Otherwise it will be divided by [/ 1.5].

[/ 1] sets à AGP Clock = 100MHz

[/ 1.5] sets à AGP Clock = 66.6MHz

AGP Clock options are:

oAuto

o÷1.0

o÷1.5
