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,
Auto". Using the "Auto, Auto, Auto" option will instruct the system to automatically calculate these
frequencies based on the factory default "CPU Host Frequency" setting, the current "CPU Host
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.

onfiguration Suggestions
Before attempting overclocking, you should write down all
variables described in the previous sections. This is so you can return to the original values if you run
into problems.
The next suggestion is to adjust in small steps and not to increase the options too fast. This is
especially true with Voltage since increasing the voltage can significantly increase temperature. After
adjusting the BIOS settings and rebooting your system, always check the CPU temperatures that ar
d
isplayed in the BIOS Setup Utility (HW Section). Tolerable temperatures for your CPU will be
listed with the specificati
ons provided by your CPU manufacturer.
Because increasing voltages is the biggest factor in increasing temperatures, you s

Formulas (using the "Auto, Auto, Auto option)
AGP frequency
= current CPU Host Frequency / 1.5
PCI frequency
= current CPU Host Frequency / 3
SRC frequency
= current CPU Host Frequency / 1
AGP frequency
= current CP
PCI frequency
= current CP
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
