DDR:CPU Ratio
This item allows you to adjust your "DRAM:CPU Clock Ratio" and overclock the DDR speeds of
the system. The options that are available for this item will depend on the factory default setting for
the "CPU Host Frequency" BIOS field according to the table below.
Factory Default
CPU Host Fre quency
100
133

AGP/PCI/SRC Speed Setting
This item determines the AGP, PCI and SRC frequencies (speed settings). You can set these
frequencies using the supplied BIOS options. One of the options available to you is "Auto,
Auto". Using the "Auto, Auto, Auto" op
fr equencies based on the factory default "CPU Host Frequency"
Frequency" setting and the formulas in the table below. Note that the factory default "CPU Host
Frequency" is the value of the "CPU Host Frequency" when you first received your system.
Factory Default
"CPU Host
Frequency"

133

To determine your new frequencies, you must first take the factory default "CPU Host Frequency"
and then determine the corresponding formulas according to the table above. Second, take the c
"CPU Host Frequency" setting and apply it to the formulas to arrive at your new frequencies.
For example, if your factory default "C
F requency" to 133, your AGP, PCI and SRC frequencies will be as follows:
AGP Frequency = 133 / 1.5 = 88.67
PCI Frequency = 133 / 3
SRC Frequency = 133 / 1
Available Options
Default (default), 2.00X, 2.50X, 2.66 X (Turbo)
Default (default), 1.33X, 1
2 .50X
tion will instruct the system to automatically calculate these
Formulas (using the "Auto, Auto, Auto" option)
AGP frequency = current CPU Host Frequency / 1.5
PCI frequency = current CPU
SRC frequency = current CPU Host Frequency / 1
AGP frequency = current CPU Host Frequency / 2
PCI frequency = current CPU Host Frequency / 4
SRC frequency = current CPU Host Frequency / 1.33
AGP frequency = current CPU Host Frequency / 3
PCI frequency = current CPU Host Frequency / 6
SRC frequency = current CPU Host Frequency / 2
