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.

Configuration
Before attempting overclocking, you should write down all of the default BIOS settings for the
variables described in the previous sections. This is so yo

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 are
displayed in the BIOS Setup Utility (HW Section). Tolerable temperatures for your CPU will be
listed with the specifications provided by your CPU manufacturer.
Because increasing voltages is the biggest factor in increasing temperatures, you should only increase
