The following item appears only when you set the Ai Overclock Tuner item to [Manual], [N.O.S.] and [X.M.P.].

PCIE Frequency [Auto]

Allows you to set the PCI Express frequency. Use the <+> and <-> keys to adjust the PCIE frequency. The values range from 100 to 150.

4.4.4DRAM Frequency [Auto]

Allows you to set the DDR2 operating frequency.

Configuration options: [Auto] [DDR2-667MHz] [DDR2-800MHz] [DDR2-835MHz] [DDR2-1002MHz] [DDR2-1066MHz] [DDR2-1111MHz] [DDR2-133MHz] [DDR2- *1200 MHz*]

The DRAM Frequency configuration options vary with the FSB Frequency settings.

Selecting a very high DRAM frequency may cause the system to become unstable! If this happens, revert to the default setting.
