performance.

BCLK Frequency [XXX]

This item appears when you set the AI Overclock Tuner item to [Manual], [D.O.C.P.] or [X.M.P.] and allows you to adjust the Internal Base Clock (BCLK). Use the <+> and <-> keys to adjust the value. You can also type the desired value using the numeric keypad. The values range from 80 to 500.

PCIE Frequency [XXX]

This item appears only when you set the AI Overclock Tuner item to [Manual] and allows you to set the PCI Express frequency. Use the <+> and <-> keys to adjust the PCIE frequency. The values range from 100 to 200.

2.4.7DRAM Frequency [Auto]

Allows you to set the DDR3 operating frequency.

Configuration options when set the AI Overclock Tuner item to [Auto] or [X.M.P.]: [Auto] [DDR3-800MHz] [DDR3-1066MHz] [DDR3-1333MHz] [DDR3-1600] Configuration options when set the AI Overclock Tuner item to [D.O.C.P]:

[Auto] [DDR3-900MHz] [DDR3-1200MHz] [DDR3-1500MHz] [DDR3-1800]

• The DRAM Frequency configuration options vary with the BCLK Frequency item settings.

•According to Intel CPU spec, CPUs with a core frequency of 2.66G support the maximum DIMM frequency of up to DDR3 1333. To use DIMMs of a higher frequency with a 2.66G CPU, enable the DRAM O.C. Profile feature in BIOS. Refer to section 2.4.2 Ai Overclock Tuner for details.

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

2.4.8QPI Frequency [Auto]

Allows you to set the QuickPath Interconnect (QPI) frequency.

Configuration options: [Auto] [4270MHz] [4800MHz]
