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.

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,
